2009-12 Acura RL changes

All information is straight from Acura's press releases

2009 Acura RL - Introduction

Acura's flagship, the new RL sedan, again proves that refined luxury need not be replete of performance adrenaline. The new 2009 Acura RL combines added performance, improved technology, more aggressive styling and safety features to Acura's premier sedan that was already top tier amongst luxury performance sedans. It would be hard to find a production car at any price that offers more advanced electronic technology or drive system sophistication. Now, the new 2009 RL allows the driver to be even more connected to the world-through improved connection with the road along with improved electronic connectivity to the world around them.

The previous RL offered an abundance of consumer friendly technology for the driver and passengers including satellite-linked Acura Navigation System with Voice Recognition™, AcuraLink® Real-time traffic information, Bluetooth® HandsFreeLink® cellular phone connectivity, DVD-Audio stereo entertainment, Active Noise Cancellation, and GPS-linked solar-sensing automatic climate control. The 2009 RL furthers cutting edge technology with the addition of new high-tech items including AcuraLink® weather, a new Note function for XM® Radio, Traffic Rerouting™, Active Sound Control, Smart Entry, Bluetooth® Audio and HandsFreeLink® that now features over 700 voice commands along with substantially improved voice recognition. Technology abounds in the drivetrain in the form of improved Super Handling All-Wheel Drive™, a revised steering rack system, upgraded coil springs, better performing shock absorbers, larger rear stabilizer bar, and more aggressive wheels and tires. Performance improves with the RL thanks to a new 3.7-liter V-6 engine that incorporates the first ever SOHC use of VTEC® valvetrain actuation for both the intake and exhaust valves.

For 2009, Acura will again offer three different trim packages on the RL:
  • RL: in addition to the potent new 3.7L V-6 engine and Super Handling All-Wheel Drive™, the RL is equipped with standard Bose® Surround Sound audio system, Bluetooth® HandsFreeLink® connectivity and solar sensing climate control.
  • RL with Technology Package includes: Acura Satellite Navigation System with Voice Recognition™, AcuraLink® Real-time traffic, AcuraLink® weather, rear view back-up camera, Active Front Lighting System (AFS), ventilated front seats, and a wood/leather steering wheel and shift knob.
  • RL with Technology Package plus CMBS™: on top of the Technology Package, the CMBS™ equipped model includes Acura's Collision Mitigation Braking System™ (CMBS™), Adaptive Cruise Control (ACC), and genuine wood instrument panel trim.
CMBS™ uses a millimeter-wave radar unit mounted inside the RL's new power plenum front grille to detect vehicles ahead to monitor potential rear-end collisions, to alert the driver when the likelihood of a collision increases, and to help reduce the impact on front occupants by pre-tensioning the front seatbelts and applying the brakes should a collision prove to be imminent.

RL with Technology Package plus CMBS™ also adds the convenience of Adaptive Cruise Control (ACC). The ACC also uses the radar system mounted inside the front grille to measure the distance between the RL and the vehicle directly ahead. To compensate for varying traffic flow, ACC continually adjusts vehicle speed by automatically applying throttle or braking to maintain a consistent following distance interval.

The innovation built into the new RL begins with the most powerful engine ever offered in an Acura sedan. An all-new 3.7-liter V-6 engine develops 300 horsepower and 271 lb-ft of torque thanks to an innovative new VTEC™ valvetrain system for both the intake and exhaust valves, a higher compression ratio, along with a special dual-stage magnesium intake manifold that enables the intake to function as a single- or dual-plenum manifold design based on engine operating parameters. In addition to developing improved power and torque, the RL engine meets tough CARB ULEV-2 emission standards and delivers good fuel economy. The RL's engine bay appears more upscale thanks to a new surround panel assembly that reduces visual distractions and focuses attention directly on the all-new 3.7-liter V-6 engine.

To handle the higher power of the 3.7-liter engine, a new version of the Sequential SportShift 5-speed automatic transmission is fitted to the 2009 RL. Featuring new "smart" F1®-style steering wheel mounted paddle shifters and a new straight-gate console mounted gear selector, the RL driver now has more gear control than ever before.

The RL's acclaimed Super Handling All-Wheel Drive™ (SH-AWD™) system returns for 2009, but is now quicker responding and better performing. There are numerous traction advantages of all-wheel drive, yet SH-AWD™ does a key function that is not available with traditional AWD systems- SH-AWD™ utilizes torque vectoring to increase the rotation speed of an outside rear wheel during aggressive cornering to help the car turn more effectively while under power. This "yaw" function reduces the cornering load on the front tires to minimize understeer, to improve handling balance, and to escalate total cornering grip.

The 2009 RL's new exterior styling is not only more aggressive, but delivers excellent aerodynamics and reduced rear lift at high speeds. The RL's more athletic style foreshadows the power beneath the new blow-formed aluminum hood. The RL's shape is taut and athletic, and its acceleration and cornering performance allow it to challenge the most capable German and Japanese sports sedans. Comfort, quietness and ride quality are also on a par with performance sedan competitors. For 2009, eight exterior colors are available-5 of which are new-including a new pearl pigment process that improves luster and shine.

To further enhance handling and ride comfort, the new RL retains a fully independent suspension system with front double-wishbone and rear multi-link architecture. For 2009 the RL features higher rate coil springs, larger diameter rear stabilizer bar, stiffer subframe mount bushings and improved design steering rack components. To further improve handling and looks, new 18-inch diameter 7-spoke aluminum wheels are matched with more aggressive tires (replacing the previous 17-inch wheel/tire offering).

Inside, the 2009 RL features a more elegantly styled interior that includes more room for rear seat passengers, easier-to-use front seat belts, front door-mounted pull pockets, softer arm rests, redesigned vents, larger/clearer lettering for HVAC controls, and easier actuation of climate control functions. A revised steering wheel and genuine wood dashboard trim (included with the CMBS™ package) and metal-look accents is now fitted to the RL along with a transmission shift knob with simulated wood trim. Complementing the steering wheel are upgraded gauges that incorporate brushed metal accents for enhanced appearance. For 2009, additional insulation, a more high-tech design of Acura's acoustic glass windshield, and a new Active Sound Control noise abatement system team to further reduce the RL's already quiet cabin.

The RL's perforated leather front seats now incorporate six levels of heated/cooled ventilation. Moreover, just like the driver's seat, the passenger front seat now has 10-way power adjustability. For 2009, the center panel controls are now more intuitive and are surrounded by a new background color along with improved quality wood patterned panels. These interior upgrades are complimented by advanced electronics that include a satellite-linked Acura Navigation System with Voice Activation™ along with the innovative AcuraLink® satellite communication system with Real-time traffic and (new for 2009) AcuraLink® weather. The RL is the first vehicle on the market to feature in-dash integrated, continually updated real-time weather information in a single-screen format. The spectacular Acura/Bose® 10-speaker Sound System with DVD-Audio returns but is now upgraded to include Bluetooth® Audio, a new Note function for XM® Radio, improved button legibility, a USB connectivity port, and even richer audio sound.

The 2009 RL retains Acura's extremely rigid Advanced Compatibility Engineering™ (ACE™) body structure that features extensive use of high-tensile steel and lightweight aluminum components to take construction beyond conventional safety protocols while keeping overall vehicle weight in check. The ACE™ structure's front-mounted polygonal main frame is designed to help prevent cabin deformation by distributing forces through multiple major load bearing pathways-and away from the passenger compartment. For 2009, to enhance safety a new Active Headrest Restraint System is built into the front seats to improve neck and head protection in the event in a rear impact collision. To further aid in safety, the RL includes as standard a passenger seatbelt reminder, Tire Pressure Monitoring System (TPMS), and six airbags. These advances team to make the RL the most powerful, best handling, most luxurious and safest sedan Acura has ever built.

MARKET SUMMARY

V-6 powered sedans are the highest volume models in the RL's segment-the mid premium segment. Because they represent the core of the market, Acura decided to build the best V-6 powered luxury performance sedan possible. Replacing the previous 290-hp 3.5L V-6 is a new 3.7L V-6 that employs Acura's first-ever SOHC use of VTEC® for both the intake and exhaust valves. The 3.7L delivers 300 horsepower and 271 lb-ft of torque that is shuttled through a new 5-speed automatic transmission and an upgraded Super Handling All-Wheel Drive™ system. By choosing not to use a V-8, which accounts for only 15-percent of the vehicles sold in this market segment, it meant that the RL would be lighter, more nimble, and better balanced.

Key 6-cylinder competitors in the RL's segment include the Audi A6 3.2, BMW 528i, Lexus GS 350, and Mercedes-Benz E350. However, with its SH-AWD™ system as standard equipment, the RL has a distinct performance and safety advantage over each of its competitors.

POWERTRAIN

Powering the RL is a new aluminum-alloy 3.7-liter VTEC® V-6 that is mounted transversely. The V-6 produces 300 hp and 271 lb-ft of torque while meeting stringent EPA TIER 2 - BIN 5 and CARB ULEV-2 emissions targets. Federal EPA fuel economy is rated at 16/22/19 mpg** (city/highway/combined).
The 2009 RL comes with a new Sequential SportShift 5-speed automatic transmission that includes larger counter shafts, revised gearing, improved clutches along with a new torque converter replete with an improved lock-up assembly. The new transmission is operated via a new straight-gate style console-mounted shifter or by way of a new "smart" F1®-style steering wheel paddle shifter system that now works when the transmission is in Drive (formerly the paddles only operated when in Manual mode). Grade Logic Control is paired with revised transmission shift programming to deliver improved performance and a crisper driving feel.

The RL's defining powertrain feature is Super Handling All-Wheel-Drive™ (SH-AWD™). For 2009 the SH-AWD™ system has been further refined to more quickly transfer a continuously variable amount of engine torque-split between the front and rear wheels as well as with the left and right rear wheels. To help the RL arc through corners with better chassis balance and more total grip, the torque vectoring SH-AWD™ system overdrives the outside rear wheel at a faster speed to generate "yaw" which helps the vehicle rotate into a turn for better, safer handling without understeer.

BODY & CHASSIS

The design of the 2009 RL body combines sophistication with a dose of performance edge to create a luxury performance sedan with an aggressive, dynamic personality.

The unit body chassis design is stiff for superior handling and utilizes a variety of steel grades in different areas where maximum strength is required. In addition, the hood, front fenders, trunk lid, frame, front and rear subframes, bumper beams and major suspension components are manufactured from aluminum to reduce weight. Some of these aluminum components are formed using an advanced "blow forming" process that allows intricate shapes to be created without increasing the weight of the part.

Careful attention was paid to smoothing airflow over, under and around the RL's body, across the windshield wipers and past the flush-mounted side glass. A cowl garnish was installed at the lower part of windshield to reduce air turbulence, while an advanced exterior-mirror design contributes to improved quietness inside the car. Under the RL, engineers further improved the myriad underbody aero panels to route airflow, improve cooling, and reduce vehicle lift at high speeds.

The 2009 RL receives a host of new steering system upgrades that deliver a more responsive, yet more linear steering feel. To further improve the RL's steering accuracy, engineers changed the diameter of the steering valves, improved the design of the steering rack guide, and incorporated an all-new compact noise isolation (CNI) steering joint. In addition, engineers developed revised electronic control parameters for the steering system.

The RL employs an independent front double-wishbone and independent rear multi-link suspension design that uses aluminum arms and steering knuckles which mount to aluminum subframes fit with stiffer frame-to-body bushings. For 2009, the new RL has further optimized chassis and suspension in the form of an upgraded electric assist power steering assembly, improved steering rack components, a new CNI joint, more performance minded coil springs, revised dampers, and a larger rear stabilizer bar. Vehicle Stability Assist™ (VSA®) with traction control, large 4-wheel disc brakes with ABS and new 18x8-inch aluminum-alloy 7-spoke wheels with redesigned tires set new standards for RL dynamic performance.

Technology is present throughout the new RL including all forms of lighting. At night, to help the driver see around corners, the RL's Active Front Lighting System (AFS) incorporates Xenon HID low-beam headlights that can swivel laterally up to 20-degrees when certain steering angle and speed conditions are met. Daytime running lights, LED turn signals integrated in the exterior mirror housings and a Center High-Mounted Stop Lamp (CHMSL) dramatically increase the 2009 RL's visibility. High tech lighting is present in the interior as well, in the form of LED backlit gauges with progressive illumination.

INTERIOR

The interior of the RL is more than just luxurious, sporty, and fully equipped with comfort and convenience features. Technology abounds in the form of the AcuraLink® satellite communication system that debuted the first ever U.S. application of Real-time traffic information as standard equipment. Standard on Navigation-equipped RL's, this feature includes continually updated traffic information for 76 metropolitan areas that the RL driver can easily access to identify traffic congestion on major roadways. The traffic information is delivered in real time via graphics displayed on the RL's navigation screen. This real time information allows the RL driver to re-route to clearer traffic areas without relying on sporadic radio traffic reports. For 2009, new technology comes in the form of Traffic Rerouting™, improved levels of restaurant information with Zagat® ratings, AcuraLink® Real-time weather information, and even a feature that allows for automated vehicle service appointments to be made while driving the RL.

Other RL technology features are equally appealing. As an example, the RL's innovative Adaptive Cruise Control (ACC) system is offered as part of the optional RL Technology Package plus CMBS™. With ACC, when cruise control is activated the system uses radar data to allow the driver to set and maintain a specific following distance interval between the RL and the car directly in front of it. Should the traffic speeds change, the ACC will compensate speed to avoid tailgating. If the driver's response does not sufficiently reduce the risk of a collision, the CMBS™ system will issue a secondary warning consisting of audible, visual and tactile elements as well as light braking to alert the driver to take action. If the closing rate increases so much that a collision becomes unavoidable, CMBS™ can initiate hard braking to reduce the vehicle's speed as well as pre-tension the driver and front passenger seatbelts to help reduce the severity of the crash.

The RL interior features luxurious styling, perforated leather-trimmed seats, and dramatic LED backlit gauges with progressive illumination. The 2009 RL further refines its premium nature with new wood trim for the dash and center console, a wood-trimmed steering wheel and shift knob, redesigned 10-way adjustable (8-way power seat plus 2-way power lumbar support)* heated/cooled front seats, more spacious rear seats, and a more logical layout of HVAC controls with easier-to-read wording.

Premium technologies define the interior just as with the powertrain and chassis. Some of these technologies include: a GPS-linked, solar-sensing, dual-zone, dual-mode automatic climate control system; an Acura/BOSE® 10-speaker surround sound system with DVD-Audio 6-disc changer that provides 500 times the clarity of a typical CD system; USB port connectivity, AUX jack connectivity and DTS® changer; and standard XM® Satellite Radio with an all-new Note function for XM® Radio feature that allows the recording of up to ten seconds of music along with the name of the artist, song title, and even the XM® channel name that can be referred to at a later time.

*Power lumbar support previously listed separately

Premium interior features continue in the form of a new Active Sound Control system that is much advanced over the previous Active Noise Cancellation™ (ANC) system. Whereas ANC dealt specifically with the elimination of low decibel noise entering the cabin, the new Active Sound Control system has a much broader range including the elimination of unwanted high frequency noise. In addition, Active Sound Control is linked to throttle position and engine rpm to provide a quieter cockpit during normal cruising while allowing the 3.7L's muscular sound to be enjoyed during higher rpm, more spirited driving.

Yet, interior technology doesn't end with noise cancellation. When you want to be heard, a new high-directional array microphone system radically improves coverage area and voice "pick up" during noisy conditions- such as when the windows are down. In addition, standard Bluetooth® HandsFreeLink® allows for hands-free phone interface that is compatible with many Bluetooth® phones (visit Acura HandsFreeLink | Bluetooth Connectivity for Acura Cars for a list of applicable phones) for a seamless cellular telephone communication experience while still devoting the driver's full concentration on the task at hand-driving safely. Other interior technologies include a Multi-Information Display (MID), a Tire Pressure Monitoring System (TPMS) with specific tire and pressure indicators, a Maintenance Minder™ system, and a new Smart Entry™ keyless entry and start system.

Premium items commonly only reserved for top end luxury vehicles, such as power rear sunshade and rear door side glass sunshades, are standard with the RL. Plus, to further separate occupants from unwanted outside noises, additional sound proofing insulation has been applied throughout the RL's cabin.

SAFETY

The previous RL earned the highest possible safety ratings (5-star) awarded during frontal (NCAP) and side (SINCAP) crash tests for outboard positions and rollover resistance tests conducted by the U.S. Department of Transportation's Highway Traffic Safety Administration (NHTSA)*. The RL is one of a select few vehicles in the history of the government test program to receive the top ratings in all three categories.
The RL also earned a GOOD safety rating from the Insurance Institute of Highway Safety (IIHS) for frontal offset and side impact tests. With the 2009 RL's front seats that incorporate a new Active Headrest Restraint System, the RL is expected to receive a GOOD rating in IIHS rear crash protection testing while maintaining the top rating in all other categories. If so, the RL (with its standard electronic stability control system termed Vehicle Stability Assist™) would achieve the IIHS's coveted TOP SAFETY PICK status.

With the RL, Acura embraces active as well as passive safety as essential goals. Active safety features can help a driver avoid an accident, and the RL includes standard items such as SH-AWD™, Vehicle Stability Assist™ (VSA®), traction control, and 4-wheel disc brakes. ABS and Brake Assist team to further enhance safety and to generate greater driver control. Xenon HID plasma-arc low-beam headlights and an optional Active Front Lighting System (that allow for up to 20-degrees of lateral headlight movement during cornering) contribute to superior nighttime visibility and enhanced safety.

Safety takes a quantum leap when the RL is optioned with the Technology Package plus CMBS™. This package adds a technological tour de force comprised of the Collision Mitigation Braking System™ (CMBS™) and Adaptive Cruise Control (ACC) systems that team to reduce the occurrence of the RL from colliding with the rear of another vehicle.

To specifically address occupant safety, the RL features Acura's innovative Advanced Compatibility Engineering™ (ACE™) front body structure. ACE™ is designed to help dissipate collision forces in frontal crashes, while enhancing crash protection for RL passengers.

The RL features a driver and front passenger dual-stage, dual-threshold airbag Supplementary Restraint System (SRS). Side curtain airbags that provide head protection for all outboard seating positions are also standard equipment. The RL has seat sensors that monitor the weight on the front passenger seat that will automatically turn off the front passenger side airbag if it detects an occupant who weighs less than 65-pounds. In addition, the RL's front passenger seat is replete with Acura's Occupant Position Detection System (OPDS) that is designed to deactivate the passenger's side airbag if a small statured person (such as a child) leans into the side airbag deployment path.

* Government star ratings are part of the National Highway Traffic Safety Administration's (NHTSA's) New Car Assessment.

CHASSIS OVERVIEW

Quick handling response, nimble performance, high dynamic capabilities, outstanding ride comfort, safety features and a fun-to-drive character aptly describe the 2009 Acura RL chassis. The RL features a highly rigid unit body teamed with an Advanced Compatibility Engineering™ (ACE™) front frame structure to provide an excellent platform for the four-wheel independent suspension. The independent front double-wishbone and independent multi-link rear suspension incorporate numerous aluminum components that reduce unsprung weight to provide better handling, more consistent traction, improved suspension response, and a more supple ride-even on rough roads. Acura's technologically advanced Super Handling All-Wheel Drive™ (SH-AWD™) system returns for 2009, and it has been upgraded with numerous improvements that deliver quicker response, more accurate torque distribution, and new control parameters for the Active Torque Transfer System (ATTS).

For 2009, the new RL has further optimized chassis and suspension in the form of an upgraded electric assist power steering assembly, improved steering rack components, a new compact noise isolation (CNI) steering joint, stiffer subframe mount bushings, more performance minded coil springs, revised dampers, larger rear stabilizer bar, larger diameter aluminum wheels, and more advanced tires. As always, ride quality and road noise isolation were also the focus of substantial engineering effort, so even with its elevated sporting performance, the RL remains quiet and composed.

CHASSIS CONCEPT

The RL was designed to compete squarely with the best luxury sedans from Germany and Japan in dynamic performance, interior luxury appointments, features and quality.

The new RL's unit body design with a fully-independent suspension, Advanced Compatibility Engineering™ (ACE™) front frame structure, and a SH-AWD™ system to provide superb handling precision teamed with outstanding safety. The suspension's optimized geometry provides linear cornering feel, outstanding dry and wet weather cornering capabilities, a flat ride, and a high level of controllability at all times. It also results in an increased feeling of precision and security for the driver and passengers alike.

FRONT DOUBLE-WISHBONE SUSPENSION

The front suspension is a double-wishbone design with a large subframe mount and a special compliance bushing. In addition, the coil spring rate has increased (by 6-percent front and 10.5-percent rear), the dampers have been recalibrated for improved performance, and the rear stabilizer bar increases in diameter by 11-percent. These upgrades combine to reduce chassis attitude changes to ensure a flat ride during acceleration, cornering, and hard braking.

Specific performance goals for the RL suspension included better response over rough roads, improved steering feel, optimized geometry, and overall component ruggedness. The steering knuckles, upper control arms, lower control arms and subframe assembly are all constructed of lightweight aluminum.

REAR MULTI-LINK SUSPENSION

The rear suspension is a multi-link design with a new enlarged subframe mount and a longer upper control arm. As a result, the vehicle roll center is optimized for better turning response, improved cornering stability and more control in extreme conditions.

The optimized geometry results in more linear toe and camber changes during suspension travel. Improved roll stiffness also enhances the RL's cornering capabilities. The suspension design also has anti-lift characteristics to reduce the pitching motion of the body during hard braking.

As a result of the new compliance bushing and the specially designed suspension, harshness and road noise are significantly reduced while ride comfort is measurably improved.

In an effort for weight savings, lightweight aluminum is used in the construction of the control arms and subframe. The components are also stiffer to withstand the higher side loads that improved SH-AWD, the larger 18-inch diameter tires and the stiff unit body design create.

ALUMINUM HYBRID SUBFRAMES

The RL employs front and rear aluminum subframes made by unique high temperature bulge-forming and high vacuum die casting methods. Both manufacturing techniques result in significantly lighter units than would be possible with traditional aluminum hydroform or steel hydroform processes.

To bulge-form these components, within a specially shaped die an aluminum tube is heated and pressurized with air. The ability to shape a component under heat and pressure means that less material can be used thus lowering the overall weight of the finished component.

The aluminum hybrid subframes on the RL save more than 40 lbs compared to comparable steel hydroformed subframes.The subframes are connected to the RL's body using new, stiffer subframe mount bushings that help deter body roll during aggressive cornering.

TIRES

Buyers of premium luxury performance sedans expect a vehicle that delivers superior cornering precision while simultaneously providing a pleasing ride. Since tires directly affect cornering ability, the RL is equipped with the largest tires ever offered on a production Acura sedan. Standard equipment are Michelin Pilot HX MXM4 P245/45R18 M+S all-season tires that deliver outstanding cornering and a compliant ride.

The new 18-inch diameter Michelin Pilot tires were specifically designed for the 2009 RL. Despite a larger wheel diameter with a shorter sidewall aspect ratio, the tires deliver better ride comfort and lower noise while simultaneously improving overall handling. Moreover, the new tire has an improved sidewall appearance compared to the previous RL's 17-inch tire.

Within the trunk of the 2009 RL is a temporary-use Bridgestone T155/70D17 spare tire mounted on a 17x4-inch 12-spoke aluminum wheel.

WHEELS

The 2009 RL features all-new 7-spoke aluminum alloy 18x8-inch wheels. The satin silver wheels not only offer more aesthetic flair versus the previous 17-inch 5-spoke wheels, but they better fill the RL body's wheel openings to generate a lowered ride height appearance. In addition, the new wheels feature a concave, back-cut spoke design (applied to the back sides of the spokes) that reduces the amount of build material used thus reducing unsprung weight for improved performance and better fuel economy.

ELECTRONICALLY CONTROLLED, SPEED-SENSING, VARIABLE POWER ASSIST RACK-AND-PINION STEERING

Precise steering performance is an essential facet of the 2009 RL. The goals were to combine a light effort, yet linear steering feel at low speeds with a heavier and more solid steering feel at higher speeds. Such a request is beyond the range of traditional steering systems, thus the RL uses a unique electronically-controlled, speed-sensing, variable power assist rack and pinion steering system. Together with SH-AWD™ and the neutral handling characteristics of the chassis, the RL is engineered to feel like a smaller car than it actually is.

Compared to traditional mechanically controlled hydraulic power steering, the RL's speed-sensing steering assist unit is controlled electronically. Not only does the system free up additional power, but the electronically controlled assist provides a very linear and direct steering feel regardless of vehicle speed. In particular, the on-center feel is very precise and linear, with no discernible "dead spot."

To further improve the RL's steering feel and accuracy, engineers changed the diameter of the steering valves, improved the design of the steering rack guide, and incorporated an all-new CNI steering joint. The previous design was constructed of a soft rubber-to-rubber coupling. On the 2009 RL, the new CNI joint has higher rigidity due to being made of steel matched higher durometer rubber. The result is better steering accuracy with more linear response. In addition, engineers developed revised electronic control parameters for the steering system.

VEHICLE STABILITY ASSISTTM WITH TRACTION CONTROL

Vehicle Stability Assist™ (VSA®) is standard equipment on the RL. VSA® uses electronic traction control and ABS functions, combined with yaw and longitudinal/lateral acceleration sensors to detect if the RL is about to understeer or oversteer. VSA® then reduces engine output and applies one or more individual brakes to help stabilize the vehicle-often done before the driver is even aware of the handling instability.

4-WHEEL VENTILATED DISC BRAKES WITH ABS AND ELECTRONIC BRAKE DISTRIBUTION (EBD)

In keeping with the athletic capabilities of the RL, Acura designers upgraded the 4-wheel disc brakes to create a true high-performance system. They targeted the braking performance of top-level competitors from Audi, BMW and Mercedes-Benz as the benchmark to meet or exceed.

Up front, 12.6-inch diameter cast-iron ventilated rotors team with 4-piston aluminum brake calipers. The multi-piston calipers are extremely rigid and are derived from racing applications. In back, 12.2-inch diameter cast-iron ventilated rotors (attached to their hub via lightweight aluminum collets) are gripped by single-piston aluminum brake calipers. For 2009, the RL receives new rear brake pads that improve performance while simultaneously reducing NVH.

The RL includes Electronic Brake Force Distribution (EBD) that automatically adjusts the front/rear brake pressure to suit conditions, while an anti-lock braking system (ABS) helps the driver retain steering control during hard braking situations. Also affecting braking performance is the RL's 4-channel Vehicle Stability Assist™ (VSA®). The combined attributes of EBD, ABS, VSA®, improved brake pads and the RL's new shocks and springs all team to deliver more reliable, better braking.

BRAKE ASSIST

Brake Assist helps drivers apply full braking pressure in an accident avoidance situation. To do so, a microprocessor continually analyzes and "learns" the driver's normal braking habits- monitoring both the rate of pressure applied and the total pressure that the driver normally applies to the brake system.

If the driver suddenly applies the brakes, Brake Assist brings the system to full ABS activation to help stop the vehicle in the shortest distance possible. It is only activated when the microprocessor detects that certain brake pedal speed and pressure thresholds are reached.

Importantly, Brake Assist helps the driver obtain full braking performance in an emergency. The Brake Assist system deactivates when the driver releases pressure on the brake pedal.

TIRE PRESSURE MONITORING SYSTEM (TPMS)

The onboard Tire Pressure Monitoring System (TPMS) with specific location and pressure indicators warns the driver when the air pressure raises/lowers in any tire. This early notification helps reduce the chance of losing control of the vehicle due to improper tire pressure. Continually monitoring pressure levels is important because a slow leak might not be detectable immediately, but over time could cause significant air loss leading to reduced tire grip or the potential of a blowout.

A sensor mounted on each wheel continually monitors tire pressure and sends a coded signal to an initiator located inboard of the tire on the chassis. The information is then sent to an electronic control unit that compares the values of each tire against an acceptable set of pressure parameters.

When a tire's pressure drops significantly below the proper specification, a "CHECK TIRE PRESSURE" alert appears on the dashboard mounted MID alert screen. The TPMS system can simultaneously display the specific air pressure in all four tires via the MID, making it simple to specifically identify a low tire.

At the driver's preference the display can continually show the air pressure in all four tires. Regardless of whether the driver chooses to monitor the pressures, a warning will still occur if a tire drops below a critical level.

BODY DESIGN & STRUCTURE

The 2009 Acura RL incorporates fresh exterior bodywork that generates a crisper, yet more muscular, luxury performance sedan. The RL combines its dynamic exterior and interior design with advanced body and chassis engineering. The result is distinctive and appealing styling, together with excellent maneuverability on the road. To ensure that the RL has exceptional dynamic capabilities and driving quality, it is outfitted with a lightweight and highly rigid body structure that makes extensive use of both high-tensile steel and aluminum components, and features 4-wheel independent suspension.

DESIGN CONCEPT

Acura designers wanted to create a taut and athletic shape that conveyed the performance capabilities of the RL without sacrificing comfort and capability.

To create an exhilarating, athletic sedan, the designers targeted superior dynamic performance, superb maneuverability, distinctively appealing styling, and a high level of active safety. The result is a top-flight luxury performance sedan able to compete with the Audi A6, BMW 5 Series, Mercedes-Benz E Class and others.

Design Image

With the new 2009 RL, Acura designers set out to employ a new "Keen Edge Dynamic" look of improved character and athleticism. To help craft the fresh design image, styling cues include the following:
  • Improved aerodynamic design with low drag and improved high-speed stability
  • A new "power plenum" front grille that is in design concert with the new Keen Edge Dynamic design grille for all new Acura vehicles
  • A new front hood constructed of lightweight aluminum and designed for increased forward visibility and reduced aerodynamic drag
  • A redesigned trunk lid that reduces rearend lift at high speed and provides added visual character
  • More aggressively styled front and rear bumpers
  • New lower rocker panel side moldings with inset chrome trim accents
  • Flush-mount side glass for reduced wind noise
  • Restyled, more aggressive front headlights that incorporate Active Front Lighting System (AFS)
  • Restyled, more aggressive rear taillights
  • Reverse gear back-up lights integrated into the rear trunk lid for improved visibility
  • New hexagonal-shaped, polished chrome dual exhaust tips
  • Five new exterior color choices
  • All-new pearl paint technology that provides improved luster
Aero Sculpture

The specific aerodynamic properties of the RL complement the styling, safety, dynamic performance, stability, human factors and other considerations. To achieve this high-performance exterior, the RL designers created a strong wedge shape that begins its "momentum" with the hood, continues it with a forward-mounted acoustic glass windshield, and finishes with a short rear overhang. The aerodynamic cabin has flush side glass for reduced drag and less wind noise. With further improved aerodynamic performance, the 2009 RL is designed to look like it moves fast.

The packaging goal for the RL was to create a taught body with short overhangs while simultaneously providing wide interior dimensions for enhanced comfort and convenience.

Controlling the weight of the RL is important for maximum acceleration, road holding and braking performance - so lightweight materials and weight-saving design are key.

BODY STRUCTURE

Light Weight

Producing a lightweight and rigid unit body was essential to making the RL a premium luxury performance sedan. Light weight construction techniques improve every aspect of the RL's dynamic performance and fuel economy, and a rigid structure improves ride and handling quality.

Specific RL strategies employed to reduce body mass include:
  • Aluminum hood, front fenders, trunk lid, and trunk lid frame
  • Aluminum front and rear subframes, suspension arms, front knuckles and bumper beams
  • Magnesium intake manifold, cylinder head covers and seat frames
  • Carbon fiber reinforced composite driveshafts
Structural Solidity

The Acura RL was also designed with the goal of creating an automobile body that provides world-class safety. It was engineered to comply with the latest FMVSS208 occupant crash protection standard and FMVSS301 fuel system integrity standard.

One of the most difficult test modes to achieve is the side collision that models the impact of a RL being struck from the side by an SUV or a pickup truck. To meet these important benchmarks, engineers increased the side section of the frame to comply with new collision regulations (see Safety section for more information). Engineers also chose different material specifications to provide the desired level of stiffness and strength for critical areas, without adding unnecessary weight.
  • The use of aluminum for the front and rear bumper beams, hood, trunk lid and front fenders saves 40 pounds compared to if made from steel.
  • Extremely strong Grade 80 high-tension steel is used for the side sills, under-floor spars, and in the impact-absorbing crumple zones at the front of the side frames
  • High tension Grade 45 steel is used on the front shock mounts, areas of the front passenger-compartment bulkhead, areas of the front subframe mounts, and rear structure
  • Grade 60 steel is used for 31-percent of the body construction
The overall result is a high level of bending and twisting rigidity for the unit body combined with enhanced crashworthiness- all with no additional weight penalty.

ALUMINUM COMPONENTS

The lightweight aluminum front fenders, trunk and trunk frame are formed with an innovative build process called blow forming to achieve complex and pleasing shapes-all with a high level of quality, low cost and lightweight construction. First, the raw aluminum panels are placed in a heated mold and warmed to 500-degrees Celsius. Next, the aluminum panels are forced into the mold with a high-pressure gas. The result is perfectly formed complex shapes that are not possible with traditional stamping methods.

For rigidity, the trunk lid is composed of an inner structural panel and an outer body panel. This 2-piece aluminum structure is crimped together with self-piercing rivets that make the lid highly durable.

DOOR CONSTRUCTION

Safety in side collisions, along with the pursuit of a quality door-closing sound, drove Acura engineers to design unique door structures. Special beams were applied for side-impact safety in both the front and rear doors.

There is no mistaking the quality sound that a well-engineered door makes as it is closes. By positioning door's center of gravity (the height at which its weight is centered) at the same height as the latch, audible vibration and the resulting closing sound can be improved. For improved entry and exit, the rear doors now open 80-degrees.

TRUNK OPENING

The 2009 RL features an all-new, more aerodynamic trunk lid. Specially designed to reduce rear lift during high speeds, the new trunk lid also provides improved styling with a European flair.

The trunk opening is reinforced to retain rigidity while providing a large, low opening for easier loading. Inside, the trunk opening is finished to hide the hinges and to cover the rain gutters (see Interior section for more information).

WINDSHIELD WIPERS

To decrease wind noise levels and improve appearance, the RL incorporates hidden pivots and wiper arms for its speed-sensing, variable intermittent windshield wipers. The pivots are hidden underneath the trailing edge of the hood line to reduce noise levels, improve aerodynamics, and enhance appearance.

The use of a hidden windshield wiper pivot is a world's first. The hidden pivot improves aerodynamic efficiency and reduces visual distraction when the wipers reverse direction. A new cowl garnish below the windshield wipers reduces air turbulance, helping contribute to a significant reduction in wind noise.

AERODYNAMICS

Careful design consideration has been paid to external and underbody design to generate excellent aerodynamics with the new RL. An efficient aerodynamic drag coefficient of 0.30 for the 2009 RL pays dividends in the form of lower wind noise, improved fuel economy, increased performance, and enhanced stability on the highway. For 2009, the RL employs new underbody aerodynamic panels that include redesigned front spoiler, engine undercover, front tire strakes, floor undercovers, rear suspension lower control arm covers, rear tire strakes, exhaust pipe aero plates, and a rear floor cover. The new, reinforced front air dam reduces front end lift while the new rear trunk lid spoiler reduces rear end lift. The RL's underbody covers not only smooth airflow, but also help with rear differential cooling.

XENON HIGH-INTENSITY DISCHARGE (HID) HEADLIGHTS

Traditional headlight bulbs illuminate a tungsten filament inside a sealed bulb containing halogen gas. However, Xenon High-Intensity Discharge (HID) bulbs use an exceptionally high voltage that passes between two electrodes to create a plasma arc. This intense arc accounts for the HID brightness and "daylight-like" illumination.

Xenon is superior to tungsten-halogen bulbs in lumens-or lighting power. The RL's Xenon HID bulbs provide 825 lumens along with a lighting pattern that is both longer and wider than that of traditional non-Xenon bulbs. In addition, the RL's tungsten-halogen high beams provide a wide illumination spread. For the driver, these advances mean greater nighttime illumination for enhanced driving confidence.

Additionally, the Xenon HID low-beam headlight bulbs have a projected life span of 1,500 hours compared to 1,000 hours for a normal bulb.

ACTIVE FRONT LIGHTING SYSTEM

The 2009 RL receives all-new, more aggressively styled front headlight assemblies with integrated brushed-style metallic surrounds and trim accents. Acura RL's equipped with the Technology Package feature an Active Front Lighting System (AFS). The AFS system uses Xenon High-Intensity Discharge (HID) headlights, 55-watt fog lights, and daytime running lights (DRL).

In the Active Front Lighting System, the left low-beam unit can swivel left and the right low beam can swivel right to improve nighttime illumination while cornering, or to help illuminate around the corner of an intersection. This improved illumination allows the RL driver advance warning if a pedestrian, animal, or object is in the way. Each HID headlight can independently swivel laterally up to 20-degrees, with the total amount of movement determined by vehicle speed and steering input.

The Active Front Lighting System uses the following components:
  • Steering angle sensor
  • Vehicle speed sensor
  • Control unit swivels the low beam headlight projector unit via a gearbox motor
  • Reverse switch (cancels AFS when car is backing up)
  • Control switch (turns off AFS at driver's discretion)
  • Instrument panel warning light (illuminates when AFS is turned off)
AFS swivels either the left or right headlight (not both simultaneously) when the following conditions are met:
  • Steering angle is over 12-degrees
  • Vehicle speed is 5 mph or higher (left-hand turns only)
  • Right-hand headlight will swivel even if vehicle is stopped
  • Swivel cancels when speed drops to 3 mph (left-hand turns only)
LED LIGHTING

The 2009 RL features advanced Light Emitting Diode (LED) lighting systems. These include side mirror-integrated directional turn signals, each of which features bright LED lights to alert motorists who are alongside when the RL driver is planning to change lanes or make a turn.

Each rear taillight assembly has an array of 28 LEDs. The taillights use 14 LEDs, arranged as the perimeter of a circle, and the brake lights use an additional 14 LEDs. When the brakes are applied, all 28 LEDs light up, illuminating the entire area. The RL's center high-mounted stop lamp (CHMSL) also uses LEDs. Besides providing a high-tech look, LED lights react quicker (they turn on/off much quicker than traditional bulbs) and produce crisper illumination which translates to greater visibility and improved safety. The projected service life of the RL's LED lights is an impressive 2,000 hours.

DAYTIME RUNNING LIGHTS

In Acura's continual commitment for safety, as with all 2009 Acura models, the new RL features Daytime Running Lights (DRL) to improve visibility while driving.

5 MPH BUMPERS

To minimize repair costs in minor, low-speed collisions, the RL has "5-mph bumpers" front and rear that are designed to absorb low speed impacts without causing any structural damage to the body panels or chassis.

NOISE VIBRATION AND HARSHNESS (NVH)

The elimination of undesirable noise, vibration and harshness (NVH) for the new RL was of primary concern to RL development engineers. Virtually everything that could be the source of these NVH traits was scientifically reviewed and modified during the planning and prototype phases.

For 2009, the RL receives more sound-deadening insulation and unique body separators that use a new stamping design along with injected foam to help quell road noise from entering the RL's interior cabin. As part of the mission to control weight, Acura used lightweight materials wherever possible in the sound-absorbing package, including lightweight sound insulators instead of traditional heavier materials. In addition, revised shock absorber parameters and new coil springs help prevent road harshness from being transmitted to interior occupants. A dual exhaust system fit with six mufflers (of differing size) reduces exhaust noise while cruising. The 2009 RL receives a new acoustic glass front windshield that incorporates an upgraded PVB film to quell wind and windshield wiper noise from entering the cabin.

An all-new, more dynamic Active Sound Control system replaces the previous (more limited) Active Noise Cancellation™ (ANC) system. Sporting a new array of processing technology and sensors, the Active Sound Control system not only dramatically improves sound cancellation but also works throughout the entire engine rpm range whereas the previous ANC system only worked to cancel engine booming noise up to 2000 rpm.

The RL's new Active Sound Control system dramatically reduces high frequency and middle-frequency noise attenuation. Road noise attenuation is also improved over both smooth and rough roads.

Key RL NVH advancements:

Drivetrain
  • Engine mounting system including a hydraulic lower transmission mount
  • Variable volume exhaust mufflers
  • Under-hood insulator
  • Engine cover and undercover
Body
  • Acoustic roof lining
  • Acoustic front and rear inner fender insulator with high-frequency damping materials

Subframes
  • Floating front and rear subframes with four mounting points
Interior
  • Active Sound Control system for noise control
  • Lightweight instrument panel damping materials
  • Thinsulate® insulation in selected areas
Trunk
  • Acoustic design with side, front and lid linings
POWER WINDOWS

The power actuated side door windows on the RL are made of safety-minded tempered glass that is 5 mm thick to reduce cabin noise. Each window features an auto-open and auto-close function, an auto-reverse safety feature, as well as key-off operation. The side glass is a special UV-coated, heat-rejection design "green glass" that helps protect occupants from harmful UV rays and excessive interior heat build-up. In an effort to further reduce cabin heat-as well as to provide added rear seat privacy-the RL features a power operated rear sunshade along with manually operated rear door glass sun shades.

FLUSH MOUNT GLASS

The Acura RL is the first car in the world to have totally flush side glass where it meets the B-pillars. Normally, a gap of about 5 mm exists between side glass and the B-pillar. On the RL, the window guide is on the glass instead of the window frame, which allows the gap to be eliminated. This design results in one continuous uninterrupted plane running along the front side window, across the B-pillar and all the way to the trailing edge of the rear side window. The benefit is improved aerodynamics, a reduction in wind noise, and a cleaner appearance.

EXTERIOR SIDE MIRRORS

To reduce wind rush and turbulence, exterior side mirror housings need to be small and aerodynamic, without unnecessarily reducing the mirror area. On the RL, the power mirror element is sized to fit inside a compact housing to reduce these unwanted characteristics.

The airflow between the mirror housing and the side window glass is crucial for reducing turbulence and noise. Engineers designed this gap as an expanding V-shape, with the gap narrower at the front and wider at the rear. This design helps the airflow decelerate as it flows across the side glass, instead of accelerating as it would if the V-angle were to decrease. The result is smoother airflow and less mid- and high-frequency noise.

For added safety, the mirrors feature integrated directional turn signals to improve visibility and to alert other vehicles of the RL's intended actions. In addition, the side mirrors are heated to deter ice or fog build-up in cold weather conditions and the mirrors feature a special coating that reduces nighttime glare. When the RL driver puts the transmission in Reverse, the mirrors tilt-down to reveal curbs and ground level obstacles to avoid. To generate added convenience, the mirrors feature driver recognition that automatically adjusts their position to preset parameters of a specific driver profile.

EXTERIOR PAINT

The exterior paint on the Acura RL uses an environmentally conscious water-based process. The painting procedure begins with an electrodeposition (ED) primer, which is electrically charged in the paint bath to help the primer better adhere to the metal bodywork. The ED primer is cured at high temperature to improve corrosive durability.

Next applied is a primer-surfacer that is hand sanded to ensure a smooth surface for better appearance. After a waterborne color basecoat is applied, a pair of clearcoats provides depth while helping to protect the base coat from air pollution, acid rain and sun damage.

Eight different exterior colors are available, including four metallic colors and four pearl colors. All eight colors are selectively available with three different interior colors. The chart below shows the available exterior/interior color combinations.EXTERIOR COLOR

SAFETY OVERVIEW

The RL is equipped with a comprehensive array of the latest technologies to enhance active safety (accident avoidance) and passive safety (crash safety performance). Features like Vehicle Stability Assist™ (VSA®) with traction control, heightened handling agility, SH-AWD™ and ABS enhance accident avoidance capability in the RL. Should a collision prove unavoidable, the Advanced Compatibility Engineering™ (ACE™) body structure of the RL is designed to provide added protection for passengers in the event of a collision with a different sized vehicle (a truck or SUV, for example). Inside the RL, side, side curtain and dual-stage front air bag systems work together with sophisticated restraint systems to minimize injury to passengers in sufficient impacts. In addition, the RL has a host of standard features that improve safety such as SH-AWD™ and an Active Front Headlight System. Also enhancing safety is a new windshield washer system with higher pump pressure and a wider spray pattern to help keep the windshield clean for improved visibility and driving safety.

OPTIONAL TECHNOLOGY PACKAGES

For 2009, Acura offers two optional Technology Packages on the RL:
  • RL with Technology Package: Acura Satellite Navigation System, AcuraLink® Real-time traffic and AcuraLink® weather, rear view back-up camera, Active Front Lighting System (AFS), ventilated front seats, and a wood/leather steering wheel and shift knob.
  • RL with Technology Package plus CMBS™: on top of the Technology Package the CMBS™ equipped model includes Acura's Collision Mitigation Braking System™ (CMBS™) that monitors the following distance and closing rate between the RL and the car directly in front of it, warns the driver when a collision is likely and helps reduce impact when a collision becomes unavoidable, Adaptive Cruise Control (ACC), and genuine wood instrument panel trim.
From a safety standpoint, the features of the two Technology Packages help make the 2009 RL one of the most comprehensively equipped vehicles in North America.

COLLISION MITIGATION BRAKING SYSTEM™ (CMBS™)

In 2006, the RL was the first Acura vehicle to offer an optional Collision Mitigation Braking System™ (CMBS™). This revolutionary safety technology monitors potential rear-end collisions, uses audio, visual and tactile signals to alert drivers to the risk of collision, assists brake operation and pre-tensions the front seatbelts to help reduce impact force on occupants and vehicle damage should a collision become unavoidable. Unlike pre-collision systems on competitive vehicles, CMBS™ automatically applies the brakes to help mitigate the severity of a collision.

Using a millimeter-wave radar unit located inside the front grille, the CMBS™ system monitors the distance between the RL and the car directly in front of it up to a distance of 300 feet along with the rate of closure between the two vehicles. If the closing rate increases to a point where a collision is likely to occur (based on relative vehicle speeds and following distance) the CMBS™ system uses visual and audible warnings to prompt the driver to take preventative action. If, based on the driver's response, the system determines that the likelihood of a collision has decreased to an acceptable level, the system will disengage. If the driver's response does not sufficiently reduce the risk of a collision, the CMBS™ system will issue a secondary warning consisting of audible, visual and tactile elements as well as light braking to alert the driver to take action. If the closing rate increases so much that a collision becomes unavoidable, CMBS™ can initiate hard braking to reduce the vehicle's speed as well as pre-tension the driver and front passenger seatbelts to help reduce the severity of the crash.

Collision Mitigation Braking System ™ (CMBS ™) Overview
  1. Stage one: When there is a risk of a collision with the vehicle ahead or if the distance between the vehicles has dropped below the pre-set level, a buzzer sounds and the message "BRAKE" appears on the Multi-Information Display.
  2. Stage two: If the distance between the two vehicles continues to diminish, CMBS™ applies light braking, and an electric motor activates the driver's seat belt E-pretensioner, retracting the seatbelt gently two or three times, providing the driver with a tactile warning. The buzzer sounds again and the word "BRAKE" appears again on the Multi-Information Display.
  3. Stage three: If, after issuing the primary and secondary warnings, the CMBS™ system determines that a collision is unavoidable, the E-pretensioner retracts the driver and front passenger seatbelts with enough force to compensate for seatbelt slack or baggy clothing and activates the brakes forcefully to reduce the speed of impact in the attempt to mitigate the collision effects on the RL and its occupants.
The CMBS™ system functions only when the RL is traveling at over 10 miles per hour and when the speed differential between the RL and the car directly in front it is 10 mile per hour or more. CMBS™ can be turned off by depressing a switch located on the left hand side of the instrument panel.

TIRE PRESSURE MONITORING SYSTEM™ (TPMS™)

An onboard Tire Pressure Monitoring System™ (TPMS™) with location and pressure indicators warns the driver when the air pressure lowers in any tire. This information helps reduce the chance of losing control of the vehicle due to low tire pressure. This is important because a slow leak (such as might be caused by a nail embedded through the tread) might not be detectable immediately but over time could cause significant air loss, reduced tire grip and potentially a blowout.

A sensor mounted on each wheel continually monitors tire pressure and sends a coded signal to an initiator located inboard of the tire on the chassis. The information is then sent to an electronic control unit that compares the values of each tire against an acceptable set of values.

When a tire's pressure drops significantly below the proper specification, a "CHECK TIRE PRESSURE" alert appears on the MID alert screen. The system can simultaneously display the air pressure in all four tires via the MID, making it simple to locate the specific low tire. If there is a fault in the system, a "CHECK TPMS SYSTEM" alert appears. At the driver's preference the display can continually show the air pressure in all four tires. Regardless of whether the driver chooses to monitor the pressures, a warning will still occur if a tire drops below specification.

ADVANCED COMPATIBILITY ENGINEERING™ (ACE™) BODY STRUCTURE

The Advanced Compatibility Engineering™ (ACE™) body structure on the 2009 Acura RL is designed to take vehicle front frame construction beyond conventional safety protocols such as the NHTSA NCAP 35 mph frontal barrier test or the IIHS 40 mph offset frontal crash. The goal of ACE™ is to deliver significantly enhanced occupant protection in a variety of real-world crash conditions. These incidents may include a frontal collision between vehicles of differing heights, weights, dissimilar frame construction design or differing bumper height.

The ACE™ structure uses the engine compartment to efficiently absorb and disperse collision energy during a frontal vehicle-to-vehicle collision. It features a frame structure composed of a highly efficient energy-absorbing main frame, a bulkhead (upper frame) which absorbs the upper part of the collision energy, and a lower member that helps prevent misalignment of the frames of the vehicles involved. This design disperses collision forces over a larger frontal area, which enhances energy absorption of the engine compartment, reduces the chance of deformation of the passenger compartment and results in enhanced occupant protection. At the same time, ACE™ reduces the chance of vertical or lateral misalignment between the RL and other vehicle's safety structures.

During a frontal collision, a conventional body structure generally concentrates the loads from the impact along two pathways running longitudinally through the lower portion of the frame. The ACE™ structure's front-mounted polygonal main frame is designed to prevent cabin deformation by distributing forces through multiple major load bearing pathways-and away from the passenger compartment.

CRASH TESTING

The RL has received the highest ratings given (5 Stars) by NHTSA in frontal and side impact testing as well as rollover resistance. In addition, the RL rated GOOD in Frontal Offset and SICE impact tests conducted by the Insurance Institute for Highway Safety (IIHS). With a new Active Head Restraint system for front seat passengers, the 2009 RL is anticipated to receive a GOOD rating in IIHS rear crash protection evaluation.
  • In the 35 mph NHTSA New Car Assessment Program (NCAP) full frontal barrier test, the RL earned Five Stars, the highest rating for both driver and front passenger
  • In the 38.5 mph SINCAP side test, the RL earned Five Stars, the highest rating for both front and rear outboard passenger
  • In the IIHS 40 mph frontal offset test, the RL earned a GOOD rating
  • In the IIHS 31 mph (50 km/h) Side Impact Collision Evaluation (SICE) test, the RL earned a GOOD rating
  • IIHS rear crash protection rating of GOOD is anticipated for the 2009 RL
*Government star ratings are part of the National Highway Traffic Safety Administration's (NHTSA's) New Car Assessment Program (www.safercar.gov). Model tested with standard side-impact air bags (SABs).

DRIVER AND FRONT PASSENGER DUAL-STAGE, DUAL-THRESHOLD AIRBAG SUPPLEMENTARY RESTRAINT SYSTEM (SRS)

Dual-stage airbags for the driver and front passenger are designed to provide protection for the head and chest during a moderate to severe front collision, while simultaneously helping to reduce injuries. The airbags do both through the use of a dual-stage, dual-threshold airbag technology. Each airbag inflator has two stages. During a severe collision both stages fire simultaneously to provide immediate airbag inflation. Yet, during a moderate collision the igniters fire in sequence, slowing the deployment rate of the airbags.

Besides monitoring the severity of the collision, the airbag modules interpret a signal from the seat belt buckle switch that indicates if the occupants are wearing seat belts.
  • If the front passengers are not wearing seat belts, the inflators will activate simultaneously to make the airbag deploy more quickly.
  • If front passengers are wearing seat belts, the airbags will inflate at a slightly higher threshold.
In the RL, the system also assesses the weight of the front passenger through a seat-mounted weight sensor. If the detected weight is less than a certain amount, the front passenger airbag is turned off. The front passenger airbag also features a seamless instrument panel cover over the airbag for a cleaner, more elegant look.

DRIVER'S AND FRONT PASSENGER'S SIDE AIRBAGS WITH FRONT PASSENGER OCCUPANT POSITION DETECTION SYSTEM (OPDS)

New larger side airbags are mounted in the outboard area of each front seatback. The airbags are designed to provide upper torso protection in the event of a sufficient side impact. The front passenger seat is equipped with Occupant Position Detection System (OPDS), an innovative system designed to deactivate the side air bag if a small child (or small-stature adult) leans into the side air bag deployment path. When the passenger returns to an upright seating position, the side air bag reactivates so it can deploy and help protect the occupant in a side impact. The system utilizes sensors in the passenger seatback to determine the height and position of the occupant, and to determine if it is safe to deploy the side air bag.

SIDE CURTAIN AIRBAGS

In a sufficient side impact, the RL's side curtain airbags deploy from roof modules, providing head protection for front seat as well as outboard rear seat occupants. Side curtain airbags effectively cover the window area from the A-pillar back to the C-pillar. Tests show that the g-forces acting upon an occupant's head are far lower with a side curtain airbag.

LATCH (LOWER ANCHORS AND TETHERS FOR CHILDREN)

The RL includes a LATCH (Lower Anchors and Tethers for CHildren) child-seat mounting system for the outboard rear seats. LATCH features built-in lower anchors and ready-to-use tether attachment points that allow compatible child safety seats to be installed without using the vehicle's seat belt system. The LATCH system simplifies child seat installation when an owner installs a LATCH-compatible child seat. The center rear seat has a tether point, but no lower anchors.

PEDESTRIAN INJURY MITIGATION

Acura's safety interests extend beyond care for vehicle occupants. The RL hood area is specially designed to deform if contact is made with a pedestrian. Underneath the hood are energy-absorbing supports and fender mounts, and the windshield wiper pivots are also deformable in the event that a pedestrian contacts these areas. Research shows that features such as these dramatically improve a pedestrian's chance of survival if struck by a moving vehicle.

INTERIOR OVERVIEW

The 2009 RL interior is designed to integrate richly elegant luxury and efficient design to create an environment in tune with the luxury performance sedan's clearly defined sporting character. At the same time, the interior incorporates the most advanced technology ever built into an Acura- operated in an intuitive and easy-to-use format. Careful integration of the advanced technology ensures that they add to the driver's comfort, control and understanding of the driving situation- all without detracting from the task of driving itself. The premium interior materials and exacting attention to detail highlight the RL's quiet interior.

The new RL interior features many new features including 10-way adjustable (8-way power seat plus 2-way power lumbar support)* front seats now with six levels of heating/cooling adjustability, roomy pull pockets added to the front door panels, optional Blackwood interior trim, longer front seat belt buckles to ease belt connection, and more room for rear seat passengers. To further improve sound isolation, the new RL makes use of more sound deadening material, an acoustic glass windshield, and an all-new Active Sound Control system that helps cancel out interior noise. In addition, revised HVAC and audio controls make for more simple function while new vent outlet adjusters provide easier operation.

For 2009 the new RL ups technology with the addition of high-tech items such as AcuraLink® weather (enabled through XM's new NavWeather® system), a new Note function for XM® Radio, upgraded Zagat® restaurant information, Traffic Rerouting™, Smart Entry, improved voice recognition now with over 700 voice commands, and a new feature that allows for automated service appointment scheduling while driving.

Acura Bluetooth® HandsFreeLink® wireless phone connectivity allows the driver to dial a Bluetooth®-enabled mobile telephone by voice command and satellite-based AcuraLink® allows communication between the RL owner and Acura-thus there has never been a more "connected" vehicle than the RL. The RL is equipped with the new Smart Entry, which allows owners to lock and unlock doors, open the trunk, and start the car without having the keyless remote in the hand.

STYLING AND MATERIALS

The quality of interior materials, fit and finish have received close attention to reflect the discerning nature of the RL owner. The large, bright navigation system display is positioned up high, in the center of the instrument panel within easy line of sight of the driver and passenger. Below the navigation system screen, the satin metal finish of the climate, audio and navigation controls has a clean, technical look. An optional upgraded wood interior sweeps across the instrument panel, is fit to parts of the steering wheel, and adorns the shift knob.

DRIVER-ORIENTED COCKPIT

Acura interior design has always made intuitive functionality a priority. All important systems and controls are within easy reach of the driver. The systems used most frequently-audio, cruise control, Bluetooth® HandsFreeLink® , satellite-linked Acura Navigation System with Voice Recognition™ and Multi-Information Display-have controls positioned on the steering wheel. The main instrumentation is an easy-to-read analog design, supplemented with digital and graphic displays. Even though the RL gives its driver access to many electronic features and conveniences, the interface is simple and welcoming. Sight lines are clear with important items placed within easy view.

Typical of Acura interior design, the soft-touch switchgear of the RL is engineered to deliver a quality feel and positive action. Helpful features make driving easier, such as power side mirrors that can be set to automatically tilt-down when Reverse gear is engaged to make parking simpler. There is also a bottom-hinged throttle pedal to provide a linear feel and natural motion. A large dead pedal on the left side of the driver-side foot well provides extra support for the driver's left foot during spirited driving.

LEATHER-WRAPPED STEERING WHEEL

The leather wrapped steering wheel incorporates the most commonly used controls, allowing the driver to keep their hands on the wheel while using them. Audio system controls are on the upper left spoke, while cruise control buttons are on the upper right spoke. The lower left spoke is reserved for navigation system controls, including a push-to-talk button to activate the voice recognition system that provides voice control of the navigation system, as well as climate control and audio system features.

Also on the left, between the spokes, are controls for Bluetooth® HandsFreeLink®. On the right, between the spokes, are controls for the MID. Tucked out of view, but within fingertip reach, are a pair of F1®-style paddles that upshift and downshift the Sequential SportShift 5-speed automatic transmission.

On models equipped with the available Technology Package plus CMBS™, control buttons for the Adaptive Cruise Control and Collision Mitigation Braking System™ are located on the upper and lower right-hand spokes.

INTERFACE DIAL

Most of the commonly used electronic functions have dedicated controls positioned on the instrument panel or on the steering wheel. Voice control of navigation, climate control, audio and communications functions are available, while an Interface Dial positioned just ahead of the center console-mounted shift lever provides another avenue of control. The Interface Dial is rotated and rocked like a joystick to select function menus displayed on the in-dash navigation screen. A push of the controller selects the highlighted item. Functions controlled by the Interface Dial include:
  • Audio
  • Navigation
  • Climate Control System
  • AcuraLink® satellite communications system
SEATING

Given the luxury mission and performance capabilities of the 2009 RL, seating required extensive engineering development. In particular, the front seats had to blend long-trip comfort with secure lateral support given the cornering potential afforded by the advanced SH-AWD™ system. For 2009, the RL receives new front seats that feature six levels of heating and cooling along with a new Active Headrest Restraint System that is expected to generate a GOOD rating in IIHS' rear crash protection test.

Replacing the previous RL's 8-way adjustable driver seat and 4-way adjustable passenger seat are new seats with 10-ways of power adjustability (8-way power seat plus 2-way power lumbar support) for both seats. Included is a power-adjustable lumbar support mechanism that, with its smooth shape of the articulated lumbar mechanism, matches the human spinal curvature to provide solid support for the occupant's torso and pelvis. All driver's seat power adjustments (except power adjustable lumbar support) are included in the new Smart Entry system that (among many other features) stores a pair of user profiles- one for each of the two key fobs that come standard with the RL.

New (1.57-inch longer) seat belt buckles allow front seat occupants to more easily find the buckle receptors when putting on safety belts. In addition, front seat occupants will also enjoy upgraded armrests with improved padding for a more luxurious feel.

For 2009, the RL offers rear seat occupants even more comfort and room. Redesigned front seat seatbacks are less bulky thus delivering improve rear seat legroom. The lower rear seat cushion has been redesigned to deliver added leg support for rear seat occupants. In the rear seat area, the outer seating positions are carefully engineered-complete with side bolsters-to simultaneously combine luxurious comfort on long trips with solid lateral support.

In front, 4-way adjustable head restraints with an Active Headrest Restraint System are adjustable for height and tilt. In back, the three headrests have a remote retractable feature that allows the driver to lower them with a touch of an overhead button for improved rearward visibility when there are no rear-seat passengers. When carrying rear seat passengers, the rear headrests can be raised manually for use.

The RL seat cushions are constructed of a special urethane with high damping coupled with a wide "S" spring design for better support of the urethane padding. These features work together to reduce the amount of road and engine vibration transmitted to the occupants while simultaneously delivering excellent passenger comfort.

MULTI-INFORMATION DISPLAY AND MAINTENANCE MINDER™

A highly functional instrument panel gives the RL driver instant access to critical information. It also provides important vehicle information via an LCD Multi-Information Display (MID) positioned in the lower section of the speedometer face. Controls positioned at the 4 o'clock position of the steering wheel hub allow the driver to cycle the MID display through multiple screens of information from sources including CMBS™ and ACC.

Trip computer functions include overall mileage, trip mileage, average and instantaneous fuel economy, average speed, fuel range, and elapsed time. The MID also displays outside air temperature, engine oil life (as a percentage), SH-AWD™ torque distribution, and individual tire pressures. The Maintenance Minder™ system alerts the RL driver of upcoming maintenance needs via the MID and should a fault occur with the vehicle, specific warning information will appear (see Engine section for more information).

INTERIOR LIGHTING

The theme of efficient driver control and easy-to-read components carries on after dark in the RL. The analog instruments are backlit with LED lighting and feature high-contrast markings with a subdued blue accent hue. The self-lighting gauge package progressively illuminates thus giving the driver a welcoming feel upon vehicle entry. When the door is first opened, the instrument lighting comes to life and then brightens progressively to 100-percent illumination when the ignition is switched on. The illuminated instrument needles and enunciator lights then come alive, indicating that the car is ready to go. At the end of the drive, the instrument lighting dims progressively.

All the interior switches are illuminated to make them easy to locate at night, including switches on all four doors and the steering wheel. In addition to front and rear overhead interior lights and map lights, the RL also has a complement of low-level interior cabin lighting. Blue front and rear ambient lighting in the ceiling illuminates the front center console and the rear flip-down armrest. The front footwells also have blue ambient lighting that brightens substantially when the doors are opened.

Front and rear interior door handle areas are illuminated to make them easy to find, and the front door storage compartments, glove compartment and the center armrest compartment are all internally illuminated. All four doors have courtesy lights that illuminate when the doors are open. The RL interior lights feature "theater dimming," which can be specifically set by the driver to any of several dimming rates via the Multi-Information Display. The trunk has interior lighting, plus the trunk lid has lighting that illuminates the bumper and sill area when the lid is opened.

INTERIOR CONVENIENCE

The RL interior offers plenty of storage and convenience features for driver and passengers. The front center armrest incorporates a unique dual lid design that allows the padded armrest to be used on one side, while the lid on the opposite side can be opened independently. Moreover, the upper portion of the armrest can be swiveled up to allow access to a large lower storage compartment that can accommodate odd-shaped items such as CD cases. New for 2009 is a USB port that allows for easy connectivity of an iPod®, iPhone® or a removable "memory stick" mass storage device. The USB port is located alongside a traditional AUX jack (that allows connectivity of MP3 music players) in the center console's lower storage compartment. Just forward of the console compartments is a dual beverage holder with an adjustable bottom tray that allows for the accommodation of a wide range of container sizes.

Inside the glove compartment is a separate document box that allows the safe stowage of the RL User Manual as well as important registration and insurance papers. The separate document box arrangement not only keeps paperwork neatly contained, but it also frees up storage space in the main glove box compartment. New for the 2009 RL are one foot long fold-out side pockets mounted in the lower portion of the front door panels.

In the rear seating area, an 8-inch wide fold-down center armrest has a padded top. A pullout dual beverage holder is built into the rear armrest. When no passengers are riding in the back, the rear seat headrests can be automatically folded down to generate improved rearward visibility for the driver.

STRAIGHT-GATE SHIFTER ASSEMBLY

The RL employs a new straight-gate shifter assembly that replaces the previous multi-gate, multi-position shifter. Located in the center console, the new shifter delivers a more intuitive, more easy-to-use design that also takes up less space on the console surface.

CARGO CARRYING VERSATILITY

The RL has a generously sized 13.1 cubic-foot trunk that is fully finished, with all wiring concealed along with the rear parcel shelf speakers and navigation unit being fully protected. The acoustic properties of the trunk and the three rear deck speakers were specially engineered to create the best possible sound performance from the Acura/Bose® DVD-Audio system. To allow room for longer and/or odd shaped items, a locking trunk pass-through is provided. A standard cargo net replete with a network of anchor points help keep trunk cargo securely in position. The spare tire is located out of sight under a folding cover built within the trunk floor.

For a cleaner appearance and to avoid damage to luggage, the lightweight aluminum trunk lid is supported by fully concealed hinge mechanisms. The trunk can be opened via a remote release mounted on the driver's door panel, by pulling the exterior release lever on the trunk lid when carrying the Smart Entry keyless access fob, or with a manual release accessible through the locking trunk pass-through. There is also an emergency trunk opener inside (located near the trunk latch) that can be found in total darkness thanks to a yellow glow-in-the-dark color treatment. For security, a switch is located in the glove box that allows the truck to be locked thus preventing access by valets. In addition, a valet key is provided that will allow a parking attendant to operate the ignition, but will not be able to open the glove box, trunk, or locking trunk pass-through if it is locked by the driver.

SOLAR-SENSING, DUAL-ZONE, DUAL-MODE AUTOMATIC CLIMATE CONTROL SYSTEM

The 2009 RL has a unique GPS-based, solar-sensing, dual-zone, dual-mode automatic climate control system that lets the driver and front passenger set temperature modes to their individual liking. A pair of large adjustable vents in the rear of the center console keeps rear seat occupants comfortable.

For 2009, easier-to-read HVAC buttons and system controls are positioned within easy reach, just below the center instrument panel vents. Also new are redesigned vent outlets with extended fin knobs for improved ease of use. The HVAC system can also be controlled by voice command, and additional custom settings can be accessed through the Interface Dial. The climate control system's control logic is designed to provide smooth operation with subtle changes in airflow. And now, changing vent airflow speed is easier than ever thanks to a new single-action fan control system that replaces the previous RL's more awkward two-stage design.

With its position-sensing ability, the GPS navigation system contributes to overall passenger comfort with a 3D solar sensing feature. Based on continuously updated vehicle position information, the navigation system determines the position of the sun relative to the driver and passenger. Combining this information with input from a solar sensor located on top of the instrument panel, the climate control system automatically adjusts the temperature and airflow from side to side as needed to compensate for asymmetrical solar heating.

System operation can be customized to suit the preferences of the driver and front seat passenger. In addition, using the navigation screen and the Interface Dial, the temperature of the air flowing through the upper vents can be fine-tuned relative to that of the air flowing from the footwell vents.

REAR SUNSHADES

For increased rear seat privacy, reduced solar loading and greater passenger comfort on sunny days, the RL has a power operated rear-window sunshade along with manually operated sunshades for each rear side window.

ACTIVE SOUND CONTROL

The 2009 RL receives a new Active Sound Control system that is much advanced over the previous Active Noise Cancellation™ (ANC) system. Whereas ANC dealt specifically with the elimination of low decibel noise entering the cockpit, the new Active Sound Control system has a much broader range including the elimination of unwanted high frequency noise. In addition, Active Sound Control is linked to throttle position and engine rpm to provide a more quiet cockpit during normal cruising while allowing the 3.7L's muscular sound to be heard more during higher rpm, higher speed driving.

Sporting a new array of processing technology and sensors, the Active Sound Control system not only dramatically improves sound cancellation but also works throughout the entire engine rpm range whereas the previous ANC system only worked to cancel engine booming noise up to 2000 rpm. Moreover, Active Sound Control is specially tuned for various levels of "effect" generated at different throttle positions: during low rpm, Active Sound Control delivers a quiet cabin; during mid-rpm throttle, some of the throaty exhaust note is allowed to enter the cabin; and during high rpm the Active Sound Control system is tuned to allow a more crisp exhaust note to enter the cabin.

The Active Sound Control system operates whenever the car is running, regardless of whether the Acura/Bose® audio system is on or off. There are two microphones mounted in the headliner- one just behind the front overhead console and another just ahead of the overhead rear light module. The microphones capture low-end drivetrain frequencies entering the cabin, and send a signal to the Active Sound Control unit. The Active Sound Control unit then creates a precisely timed reverse phase audio signal that is sent to an amplifier, which powers the door speakers and the subwoofer positioned on the rear deck.

The Active Sound Control dramatically reduces the booming sound of the exhaust, front and rear. In the frequency range below 100 hertz, Active Sound Control results in an impressive 10 dB reduction in noise level. Moreover, the new Active Sound Control system dramatically reduces high frequency and middle-frequency noise attenuation during normal cruising. In addition, road noise attenuation is also improved over both smooth and rough roads.

OVERHEAD CONSOLE

An overhead console in the RL incorporates a variety of useful features. Controls for the standard HomeLink® system and other overhead console features include controls for interior lighting, power sunroof, power rear sunshade and remote retracting rear head restraints.

ACURA/BOSE® 10-SPEAKER SURROUND SOUND SYSTEM WITH 6-DISC CD, DVD-AUDIO AND DTS® CHANGER AND AM/FM TUNER

The RL comes standard with a DVD-Audio system that is engineered to advance the state of the art in production car audio. The ultra-sophisticated system in the RL provides the driver and passengers with a new level of audio enjoyment utilizing a Bose® Cabin Surround® audio system.

Engineered specifically for the RL, the Acura/Bose® 10-speaker Surround Sound System with 6-disc CD, DVD-Audio, DTS® changer and AM/FM tuner delivers surround sound to all seating positions. In addition, the RL's sound system features as standard XM® Satellite Radio that provides 170 channels of digital programming with near-CD quality sound. A text display on the navigation screen provides information on the current program material. XM® provides virtually uninterrupted coverage within the 48 contiguous United States and some of Canada, and a complimentary 3 month XM® subscription is included with the RL. (Note: XM® Satellite Radio is not installed on RL models sold in Alaska and Hawaii as service for these states does not exist at this time.)

The RL's audio system includes a new Note function for XM® Radio that makes it easy to identify songs for later remembrance or purchase. With push of a button, the Note feature can capture a 10 second portion of up to 30 different songs, along with text indicating the song title, artist name, and XM® channel.

The RL has a 6-disc in-dash CD changer that can play DVD-Audio, CD, and MP3 media. DVD-Audio is the next step in audio reproduction technology. Many new music releases are issued in this format, and many older recordings are being re-mastered and reissued to take advantage of the superior sound that DVD-Audio offers. With over 500-times higher resolution than traditional CD audio, DVD-Audio delivers smoother, fuller and far more accurate sound. The DVD-Audio system will not play DVD movies, DVD-Video or DVD-R/RW discs.

To improve sound quality when playing traditional CDs, the sound system includes Centerpoint® logic, which creates simulated surround sound from the two channels of CD data. Another feature, Audiopilot®, automatically adjusts the audio signal in response to exterior noises. Audiopilot® monitors the sound in the RL cabin using the same array microphone used for the Active Sound Control, and then the system adjusts the audio output to compensate. Centerpoint®, Audiopilot®, balance, fader and other functions can be accessed via the easy-to-use Interface Dial. Controls for key audio system functions are positioned within fingertip reach on the RL steering wheel. Select audio system functions can also be accomplished via voice commands.

For more precise audio imaging and impressive sound for listeners in the front and rear seats, 10 speakers are strategically located throughout the RL cabin. Each front door has a 6.5-inch full-range speaker and a separate 1.5-inch tweeter. A 2.5-inch twiddler is centered on the top of the instrument panel. Each rear door has a 6.5-inch full-range speaker, the rear parcel shelf has a 2.5-inch twiddler on each side, with a big 9-inch subwoofer centrally located beneath the rear glass. A total of 260 watts of power drives the 10-speaker system.

In addition to DVD-Audio and traditional CD source inputs, the 2009 RL is fitted with a new USB port that allows for easy connectivity to an iPod® (5th generation or later Apple iPod® or 2nd generation or later iPod Nano®) or iPhone® along with removable "memory stick" mass storage device containing WMA or MP3 format music. The USB port is located alongside a traditional AUX jack (that allows connectivity of MP3 music players) in the center console's lower storage compartment.

The RL's audio system control panel has been upgraded for 2009 to include a larger font size for wording, a color change, and a darker background color for added contrast and improved readability.

BLUETOOTH® HANDSFREELINK® WIRELESS TELEPHONE INTERFACE

Like all Acura's, the RL has a standard Bluetooth® HandsFreeLink® hands free phone interface that is designed to work with many Bluetooth®-enabled mobile phones. Bluetooth® is a radio frequency-based technology that allows portable devices like mobile cellular telephones, PDAs, laptops and other devices communicate wirelessly. The RL's HandsFreeLink® system is compatible with Bluetooth®-enabled cellular phones that have the Hands Free Profile (HFP). (Some early Bluetooth®-enabled phones do not have this communications protocol, but most newly released phones have HFP.) After the driver completes a one-time pairing process, the RL can communicate wirelessly and securely with the driver's cell phone when it is within approximately 10 feet of the car. The phone needs to be on, but can be stowed in a pocket, briefcase, purse, or anywhere inside the RL cabin-thus there is no need to worry about where to place the cellular telephone.

Bluetooth® HandsFreeLink® allows the driver to send or answer telephone calls without removing hands from the steering wheel. When a call comes in, the number of the incoming caller is displayed on the Multi-Information Display (MID) located in the speedometer face. In addition, the phone ring tone is played over the audio system. If the driver chooses to answer the phone call, a press of the steering wheel-mounted "Pick up" button mutes the audio system and the incoming caller is heard over the RL's audio system speakers. Working with a new overhead array microphone, the HandsFreeLink® system cancels "echo effect" and reduces background noise to improve the transmission quality of the driver's speech.

To send a call hands free, the driver can dial the number by voice, again using fingertip controls mounted on the steering wheel to activate the system. The driver also can store frequently called numbers in the system's memory using unique voice tags. Up to six different compatible mobile phones can be paired with the RL's Bluetooth® HandsFreeLink® system at one time.

Additional information can be found at Acura HandsFreeLink | Bluetooth Connectivity for Acura Cars.

ACURALINK® SATELLITE COMMUNICATION SYSTEM WITH REAL-TIME TRAFFIC

RL models within the 48 contiguous United States feature the AcuraLink®satellite communication system with Real-time traffic (when equipped with the Technology Package). AcuraLink® allows for two-way communication between Acura and the vehicle, providing customers with the latest information specific to their vehicle. In cases where communication to and from the Acura Telematics server is needed, the owner's Bluetooth® phone is used (once the owner has enabled its data-transmission function).

AcuraLink® messages consist of a limited amount of text plus expanded details via Text-To-Speech. Each message is prioritized by importance. High priority messages are displayed immediately upon receipt. Other messages trigger an icon on the RL navigation display. Some low priority messages show up only on vehicle start-up to avoid distraction. In all cases, the RL owner can choose to read or listen to the message immediately, or archive it to be retrieved at a later time.

A wide variety of messages can be sent to the RL, including Maintenance Minder® (detailed information regarding your next required maintenance), Quick Tips (information to help you maximize the benefit and enjoyment of RL features), Feature Guide (supplements to the RL Owner's Manual), Diagnostic Info (detailed information and instruction should an onboard system issue arise), and information regarding required vehicle service or repair. The RL owner has complete control over the types of messages they receive. All AcuraLink® preferences can be set via the Owner Link website (www.ahm-ownerlink.com).

Since the system allows two-way data communication between the RL and the Acura Telematics Server, AcuraLink® can provide the owner with vital information that previously has been unavailable. For example, if a warning light should appear on the RL instrument panel, AcuraLink® can be configured to automatically send a trouble code along with the sensor data associated with the fault to the Acura Telematics Server, which analyzes the code, then sends a message back to the RL-such as "A software issue has been detected. It is OK to continue driving. The repair is currently being developed, so you do not need to visit your dealer at this time." You will receive another AcuraLink® message when it is time to visit your dealer to have the system repaired. This way, the owner knows if a particular fault is serious enough to cancel a trip, if it can be dealt with later or if it requires special driving techniques. An icon on the RL navigation display screen indicates an incoming message.
A wide variety of messages can be sent to the RL, including Maintenance Minder™, Quick Tips, Feature Guide and Diagnostic Info. The RL owner can set their preferences for the types of messages they receive in their RL via the Owner Link website.

Since the system allows two-way data communication between the RL and the Acura Telematics Server, AcuraLink® can provide the owner with vital information that previously has been unavailable. For example, if an ABS/BRAKE warning light should appear on the RL instrument panel, AcuraLink® will automatically send a trouble code to the Acura Telematics Server (if the customer selects this preference), which interprets the code, then sends a message back to the RL, such as "ABS and EBD shut down! Drive slowly. Avoid sudden hard braking." This way, the owner knows if a particular fault is serious enough to cancel a trip, if it can be dealt with later or if it requires special driving techniques. The data connection is enabled even if the monthly XM® service package is not in effect.

ACURALINK® REAL-TIME TRAFFIC INFORMATION

The navigation screen can display up-to-the-minute traffic information including flow, accidents, unusual incidents, construction and weather on freeways in 76 major metropolitan areas. The information is part of the XM NavTraffic® feature (aggregated by NAVTEQ™ from multiple sources including police and highway patrol accident reports and transportation departments), and then is transmitted by XM® satellites to the vehicle where it is graphically displayed on the RL's navigation system from a 1/2- to 5-mile scale.

The RL owner can click on an icon on the map to see incident details or select Traffic Incidents by pushing "Enter" on the Interface Dial. Traffic information is continuously updated, allowing drivers to avoid congestion en route and choose the fastest path to their destination. Moreover, you can see traffic incidents, determine average traffic speed and estimate travel time along your chosen route, as you drive it. It can even automatically recalculate results as factors change. Plus, XM NavTraffic® alerts drivers of scheduled traffic incidents such as construction and road closures, plus unscheduled incidents such as accidents and disabled vehicles.

For 2009, the RL's Acura Satellite-based Navigation system advances with new Traffic Rerouting™ functionality, utilizing live data from AcuraLink® Real-time traffic information. When traffic congestion or road incidents are detected along the selected drive route, Traffic Rerouting™ can automatically recalculate a "detour" route and display a pop-up box signifying the route change. The RL driver can also recalculate a route in manual mode simply by selecting "TRAFFIC INCIDENTS" from the Map Info menu followed by selecting the "AVOID" command relevant to an incident. Either method can save time and frustration, thus keeping the Acura driver ahead of the curve. (Note: Traffic Rerouting™ requires a monthly subscription to the XM NavTraffic® service).

With the average rush-hour commuter spending over 50 hours a year sitting in traffic, AcuraLink® Real-time traffic with Traffic Rerouting™ gives RL owners a useful time saving tool on freeways. Unlike sporadic radio or television traffic reports, Real-time traffic provides a constant flow of relevant information reflecting conditions along a driver's chosen route. Real-time traffic data services are offered on a subscription basis for a nominal fee following the 3-month free trial period. In addition to the on-screen traffic information, RL owners who maintain their XM® Satellite Radio service also receive more general audio traffic information that runs on a 2-3 minute loop in selected metropolitan areas.76 major metropolitan markets

ACURALINK® WEATHER

Acura was the first automotive company to offer continually updated "real time" traffic information as standard equipment. Now, Acura again leads the technology front as it is the first to offer an in-dash navigation system with integrated Real-time weather information displayed in a single-screen format. In short, it's almost like having a weather man in your car.
Key features
  • All-new in-dash, single screen integrated AcuraLink® weather
  • Professional grade weather information provided by Baron Services, Inc.
  • Real-time weather information for 21 specific metropolitan areas
  • 1- or 3-day future weather forecasts
  • Severe weather alerts
  • Specific area weather information
AcuraLink® weather (co-developed with XM NavWeather®) is a personal weather tracking system for in-dash automotive GPS navigation system. The system tracks area specific, real-time weather conditions between your current location and your final destination. Plus, it provides near-term weather forecasts. Rather than just offering general weather conditions for a region, the system focuses on the specific weather on your personal drive route. Real-time weather information is continuously updated and delivered to the vehicle navigation system via the RL's built-in GPS satellite receiver.

With data provided by Baron Services, Inc., professional grade weather information (obtained and deciphered from a complex array of National Weather Service information) is now exclusively available to Acura owners. Owners of a new RL will receive a complementary 3-month trial subscription that delivers AcuraLink® weather along with AcuraLink® Real-time traffic and XM® satellite radio. Afterwards, AcuraLink® weather is available alone by monthly subscription or packaged with Real-time weather, with XM® satellite radio, or as a combined package of all three features.

Implementing XM's® proven WX Weather that is the recognized weather information leader in the aviation and marine markets, the AcuraLink® weather technology is further enhanced for specific travel conditions across the United States including 21 specific major metropolitan areas. The information focuses on identifying potential weather threats along with current and future forecast weather conditions.

Current weather conditions are displayed on the navigation screen in an easy-to-read format. Or, if you wish to learn of nearby weather conditions elsewhere than your current driving location, simply move the RL's navigation system cursor to the desired location on the map to obtain info for a specific location. When finished, simply press the "Map" button and information regarding your current location will return.

In addition to providing continually updated weather information, unique Threat Matrix Technology within AcuraLink® weather generates prompts with specific icons (within 46 different categories) informing the RL driver if the vehicle is headed into oncoming severe weather such as a developing snow storm, tornado warning, or ice. With such advance information the RL driver can choose to reroute driving to avoid the severe weather before actually encountering the weather.

If you zoom out all the way on the navigation screen (thus revealing the entire United States), Real-time weather will shows a global look at weather patterns across different areas of the country. Furthermore, if you plan on traveling to different states, Real-time weather offers 1- or 3-day weather forecasts for specific areas of the United States.

System Operation

Based on positioning data from up to 12 orbiting Global Positioning Satellites (GPS), the Acura Navigation System with Voice Recognition™ tracks the RL's position. If the GPS antenna is blocked by a tunnel, tall building or parking garage, an internal gyroscopic system and a speed sensor track the location of the vehicle to keep the mapping information current and reliable until satellite reception is restored. A mapping DVD is located in the trunk within the system's ECU. Updated DVD data discs are available for purchase on an annual basis on-line or by calling 888-549-3798.

The navigation system can be controlled by voice command or by using the Interface Dial. For voice operation, the driver simply presses the "Talk" button on the steering wheel and says any of a number of preset command phrases. The system responds to over 700 command phrases, as well as to spoken city and street names.

When the "Talk" button is pressed, the audio system is automatically muted, and an all-new overhead array microphone receives the command from the driver. Commands can be given in plain English, like "Display gas stations", "Find nearest hospital", or "Find nearest Chinese restaurant." You can choose to display points of interest on the map (such as restaurants or grocery stores), or have the system provide turn-by-turn navigation-all by voice command. The extensive point-of-interest database includes phone numbers, which can be dialed easily by using the Bluetooth® HandsFreeLink® system and the driver's cell phone. Plus, with HandsFreeLink® and a proper Bluetooth® enabled cellular phone you can automatically import your cell phone's phonebook into the navigation system's database.

The Acura Navigation System with Voice Recognition™ can also be controlled via the Interface Dial by choosing menu options or spelling out a word (e.g., an address, business name or place) using the Interface Dial much like a computer mouse to select characters from an on-screen keypad.

The onboard database includes a Zagat® Survey Restaurant Guide. The Interface Dial makes it easy to operate the system as well as to find and select destinations. Voice recognition capability saves time and simplifies operation of the system. The 2009 RL's revised voice recognition technology allows the RL owner to simply speak city and street names aloud, and the system responds by displaying matches available in the database.

ADAPTIVE CRUISE CONTROL (ACC)

For 2009, Acura again offers an optional Technology Package with CMBS™ for the RL that includes Adaptive Cruise Control (ACC). This new vehicle speed and distance control system uses a grille-mounted millimeter-wave radar unit to monitor the distance between the RL and the vehicle directly ahead. Like a conventional cruise control system, the RL's ACC can maintain a pre-set speed. In addition, by combining radar data with data from speed sensors, ACC can regulate the RL's speed to maintain a pre-set following distance interval between it and the vehicle directly ahead. The system is designed for use on open highways and works only when the RL is traveling over 25 miles per hour.

The system is activated by pressing the "ACC" button on the upper right-hand spoke of the steering wheel. When this button is pushed, "ACC" will appear on the Multi-Information Display (located directly below the speedometer) indicating that the ACC system has been turned on. To select the ACC cruising speed, the driver accelerates to a chosen speed and presses the "Decel/Set" button, which is also located on the upper right-hand spoke of the steering wheel. Once selected, the chosen cruising speed is shown on the Multi-Information Display.

The following distance interval is selected by pressing the "Distance" button on the lower right spoke of the steering wheel. Using this button, the driver can choose one of three following intervals: approximately 1 second, 1.5 seconds or 2 seconds, based on the speed of the RL along with the following distance the driver wants to maintain from the car directly ahead. Each time the button is pressed, a "vehicle-shaped" icon on the Multi-information display changes to reflect the chosen following interval:
  • One bar representing approximately a 1-second interval
  • Two bars representing approximately a 1.5-second interval
  • Three bars representing approximately a 2-second interval
Once ACC is activated, the system's electronic control unit (ECU) adjusts the throttle and applies light braking to maintain the chosen following distance interval between the RL and the car directly in front of it. If a vehicle from another lane cuts in front of the RL (between the RL and the car that it has been following) the system will beep and the "vehicle" icon will flash on the Multi-Information Display to alert the driver that a new vehicle has been detected. The system then adjusts the throttle and applies braking to maintain the pre-set following interval between the RL and the new vehicle. A vehicle icon will appear each time a vehicle moves into the ACC system's range. Conversely, when a vehicle moves out of the system's range, the icon changes to an "outlined" image. If the vehicle directly ahead of the RL brakes suddenly, a series of beeps will sound and the word "BRAKE" will appear on the Multi-Information Display warning the driver to apply the brakes.

If the vehicle directly in front of the RL accelerates out of the radar's detection zone or moves to another lane, and another vehicle is not within the system's range, ACC will gradually accelerate the RL until the pre-set cruising speed is achieved. When a vehicle moves out of range, the "vehicle icon" on the Multi-Information Display will change from solid to outline.

The driver can switch between ACC and conventional cruise control by using the "Distance" button located on the steering wheel. Cruise control system status is displayed continuously on the Multi-Information Display.

Because the ACC system's millimeter-wave radar can be affected by rain, snow, fog and other types of inclement weather, the ACC system should not be used during these conditions.

SMART ENTRY KEYLESS ACCESS SYSTEM

The RL features a new Smart Entry vehicle access system with driver recognition for driver's seat, steering wheel, outside mirrors, climate control, audio system settings and presets, and select navigation system settings. This feature allows the RL owner to gain access to the car without ever having to unlock it with the remote transmitter or key. The keyless remote has an electronic unique digital identity. The car can be unlocked when the driver grasps one of the front doors with the keyless remote in his/her possession.

Once the driver has opened the door and is seated, the Smart Entry allows the RL to be start by rotating the ignition switch without inserting a key into the ignition.

To unlock the door, the driver must have the keyless remote in their possession. The remote can remain in a pocket or briefcase as it isn't necessary to have it in hand. The driver simply approaches the car and grasps the door handle to the door.

To lock the doors upon leaving the car, simply touch the raised dimple on outside of the door handle. Alternatively, you can press the Lock button on the keyless remote. All doors will lock simultaneously.

Approaching the driver's side allows the opening of the driver's door only whereas when approaching the passenger's side all four doors can be opened. Via the Multi- Information Display's selectable unlocking feature, the RL owner can preset a preference to have all four doors unlock when the driver's door is engaged.

To open the trunk, simply approach with the remote and pull the lever as it will automatically unlock so you can open the lid. The system will not allow the recognized transmitter to be locked in the trunk.Smart Entry also features a unique "quick vent" feature that (when holding the "unlock" button on the keyless remote for two seconds) instantly lowers all four door windows along with opens the power moonroof to quickly vent built-up interior heat. In addition, by holding the key in the "lock" position, all open windows can be simultaneously raised.

Preferences

The Acura RL comes with two keyless remotes. Each keyless remote can be set with a unique preference, for instance to accommodate the preferences of a husband and wife.

The preferences include driver seat, steering wheel and mirror positions along with select HVAC functions. Other preferences include turning entry lights on or off, audio system pre-sets, air conditioning preferences, and navigation system settings. In the event both owners plan to use the car at the same time, the RL will recognize the keyless remote that approaches first.

Built-in Key

A built-in mechanical key is provided as a back up in the event that the keyless remote battery should fail, although the vehicle will signal the driver when the remote battery is low. In this case the RL can be started with the built-in key. For security purposes when using a valet parking service, you can push a trunk lockout switch located inside the glove box, and then lock the glove box and the trunk pass-through with the key. Take the built-in key from the keyless remote and keep it, then give the keyless remote to the attendant. The valet will be able to start and drive the RL but will be unable to unlock the glove compartment or trunk.

2009 RL INTERIOR ACCESSORIES

A line of Genuine Acura Accessories was developed simultaneously with the RL to provide personalization for the Acura owner. Like all Genuine Acura Accessories, the RL accessories are covered by a 4-year/50,000-mile limited warranty.
