The road-racing-inspired Camaro 1LE performance package returns for 2013 with unique gearing, suspension tuning and tires that make the model capable of more than 1 g of lateral acceleration and a sub-three minute lap time at Virginia International Raceway’s Grand Course. It is offered on Camaro SS coupes with manual transmissions.

All Camaro SS models now feature variable-effort electric power steering and an available dual-mode exhaust system on manual transmission-equipped models. Both features were introduced on the Camaro ZL1.

The 2013 Camaro lineup includes:

• The 323-horsepower (241 kW) V-6-powered LS coupe and LT coupe and convertible – including the 2LS with an EPA-rated 30 mpg on the highway
• The Camaro SS coupe and convertible, with a 6.2L V-8 delivering up to 426 horsepower (318 kW)
• The 580-horsepower (432 kW) supercharged Camaro ZL1 coupe and convertible. (Please see the separate Camaro ZL1 release for complete details.)

In addition to the new performance features offered on the Camaro SS, all 2013 Camaro models offer a wider range of choices and enhancements that will help it remain America’s most popular sports car. New and revised content includes:

• Chevrolet MyLink and color-touch radio standard on LT, SS, and ZL1 models
• Chevrolet MyLink and color-touch radio with GPS map navigation (late availability)
• Hill start assist now standard on all manual transmissions
• ZL1-style shift knob standard on all manual transmissions
• Remote vehicle start now include on 1LT and 1SS with automatic transmission
• Blue Ray Metallic exterior color
• Frameless inside rearview mirror
• New 18-inch and 20-inch wheel designs
• Mojave leather interior trim.

1LE details

The 1LE package is offered on 1SS and 2SS coupe models with an exclusive Tremec TR6060-MM6 six-speed manual transmission. Paired with a numerically higher 3.91 final-drive ratio, the close-ratio gearing of the transmission is tuned for road-racing performance. As with the ZL1, the 1LE transmission features a standard air-to-liquid cooling system for track use.

The 1LE also features exclusive, monotube rear dampers instead of the twin-tube dampers on SS models. The new hardware allowed engineers to tune the 1LE suspension to focus on optimal body-motion control while preserving much of the ride quality and wheel-motion control of the Camaro SS.

Other changes to optimize the 1LE for track-day use include:

• Larger, 27-mm solid front stabilizer bar, and 28-mm solid rear stabilizer bar for improved body control
• Higher-capacity rear-axle half shafts to cope with increased levels of traction
• Strut tower brace for improved steering feel and response
• ZL1-based 20 x 10-inch front and 20 x 10-inch aluminum wheels
• 285/35ZR20 Goodyear Eagle Supercar G:2 tires front and rear (identical to the front tires for ZL1)
•ZL1 wheel bearings, toe links and rear shock mounts for improved on-track performance
• ZL1 high-capacity fuel pump and additional fuel pickups for improved fuel delivery during high-load cornering.

Visually, the 1LE package is distinguished by its matte black hood, front splitter and rear spoiler – as well as the 10-spoke ZL1-based wheels, which are finished in black. The functional front splitter and rear spoiler contribute to the car’s on-track performance by helping to reduce aerodynamic lift at high speeds.

Inside, the 1LE package incorporates the ZL1’s flat-bottom steering wheel, trimmed in sueded-microfiber and designed for easier heel-and-toe driving on the racetrack. The quick-acting, short-throw shifter from the ZL1 is also trimmed in sueded-microfiber.

In anticipation of consumers entering the 1LE in amateur-racing events, Chevrolet is pursuing SCCA approval of the 1LE package for Touring Class competition.

The Camaro 1LE package was introduced in 1988, inspired by Camaro’s involvement in Pro-Am road racing.

MyLink details

Chevrolet’s color touch radio with MyLink infotainment is available on 2013 Camaro LS, SS and ZL1 models. The color touch radio, with a seven-inch touch screen, also can be paired with an available in-dash GPS navigation system – a first for the Camaro.

The color touch radio with MyLink gives customers a higher level of in-vehicle wireless connectivity and customized infotainment options, while building on the safety and security of OnStar. It seamlessly integrates online services such as Pandora® internet radio and Stitcher SmartRadio® using hands-free voice and touch-screen controls via Bluetooth-enabled phones.

MyLink adds stereo audio streaming and wireless control of smartphones, building on the voice-activated Bluetooth hands-free calling capability already offered in most Chevy vehicles. The high-resolution, full-color touch screen display makes media selection easy to navigate. MyLink also retains all the capabilities of today’s entertainment functions, including AM/FM/Sirius XM tuners, auxiliary and USB inputs.

Camaro design and exterior features

Camaro’s heritage-inspired interior and exterior convey sportiness through iconic design cues. A rear spoiler is standard on all models and a variety of stripe packages offers a broad range of personalization features.

LT and SS models are available with the RS package, which adds 20-inch wheel, body-color roof moldings and antenna, as well as high-intensity discharge headlamps. Eighteen-inch wheels are standard on LS and LT model, with 20-inch wheels standard on SS.

The Camaro convertible brings top-down driving fun and style to LT and SS models. And because the architecture for the fifth-generation Camaro was designed to accommodate a convertible model, it gives the cars coupe-like driving dynamics. Four strategic reinforcements enhance the already-stiff body structure to quell the cowl and steering wheel shake common in convertibles. They include:

• A tower-to-tower brace under the hood
• A transmission support reinforcement brace
• Underbody tunnel brace
• Front “X” brace and stiffer cradle as well as rear underbody “V” braces.

All convertible models feature a standard rear vision camera system. It is also standard on 2LT and 2SS models and available on 1LT and 1SS.

Exterior colors include Summit White, Black, Crystal Red Tintcoat, Victory Red, Rally Yellow, Inferno Orange Metallic, Ashen Grey Metallic and Blue Ray Metallic. The convertible top color choices include black and beige.

Camaro interior features

Camaro’s well-executed balance of heritage and contemporary features provides a fun and comfortable environment for up to four. An ambient lighting package on 2LT and 2SS trims gives the interior a special glow with LED light pipe technology.

Driver and passenger seatsfeature six-way adjustable settings (fore/aft, up/down and tilt), with power recline front seats that are standard on LT and SS models. Heated, leather-trimmed seats are part of the 2LT and 2SS trim packages.

Additional comfort and convenienceinclude a standard driver’s foot rest (dead pedal), power windows with express up/down, an auxiliary gauge panel in the center console – standard in 2LT and 2SS – and a new ZL1-inspired shift knob for all manual transmissions. A leather-wrapped, three-spoke steering wheel is standard on LT and SS.

A head-up display, which projects key instrument, Turn-by-Turn navigation and audio system details on the windshield, is part of the 2LT and 2SS trim packages. And complementing the new MyLink infotainment system is a six-speaker sound system on LS, 1LT and 1SS. A 245-watt, Boston Acoustic nine-speaker sounds system is standard on 2LT and 2SS – and available on 1LT and 1SS.

Interior color and trim choices include Black, Beige, Gray, Inferno Orange and Mojave. The Inferno Orange and Mojave combinations include contrast stitching and other details.

Camaro powertrains

Standard in LS and LT models is the LFX-code 3.6L V-6, rated at 323 horsepower (241 kW) and enabling EPA-estimated 30-mpg highway mileage (2LS model). Many lightweight engine features contribute to that, including an integrated cylinder head/exhaust manifold design that saves about 13 pounds per engine, when compared with a conventional, non-integrated design.

Two 6.2L V-8 engines are offered in the Camaro SS, including the L99 on automatic-equipped vehicles and the LS3 on manual-equipped models. Horsepower for the L99 is 400 (298 kW) at 5,900 rpm and torque is 410 lb.-ft. (556 Nm) at 4,300 rpm. The LS3 develops 426 horsepower (318 kW) and 420 lb.-ft. (569 Nm). Output on the L99 is lower than the LS3 because of a slightly lower compression ratio (10.4:1 vs. 10.7:1) and design features of the Active Fuel Management system.

All Camaro models can be equipped with either a six-speed manual or six-speed automatic transmission with TapShift. Equipment and features include:

• The Aisin AY6 six-speed manual is standard with the 3.6L engine, and a Hydra-Matic 6L50 six-speed automatic is optional
• A Tremec TR 6060 six-speed manual is standard on the SS, and the Hydra-Matic 6L80 six-speed automatic is optional
• The SS model’s Tremec TR6060 six-speed manual is designed to handle the high torque characteristics of the LS3 engine and is matched with a 3.45:1 final drive ratio
• A close-ratio version of the Tremec TR6060 is used with the 1LE package and is matched with a 3.91 final drive ratio
• Hill start assist is standard on all manual transmissions.

A dual-mode exhaust system is available on Camaro SS models with the six-speed manual transmission. Similar to the systems found on the ZL1 and Corvette models, this vacuum-actuated system provides a quieter driving experience at low engine speeds and a more aggressive sound at when aggressive acceleration is called for.

Camaro chassis and suspension

Camaro features fully independent front and rear suspensions, with the rear suspension featuring a 4.5-link system that includes a unique, L-shaped upper control arm that attaches to the knuckle at one end and incorporates a ride bushing in the rear. A sub-frame at the rear is double-isolated to minimize vehicle body motions and dampen road imperfections. Coil-over shock absorbers are used in the rear with a decoupled, hollow stabilizer bar. The front suspension has a dual-ball strut system, with a direct-acting stabilizer bar.

Four suspension packages are offered: FE2 sport on LS and LT models; FE3 on SS Convertible models, FE4 performance on SS Coupe models and the FE6 with the 1LE Performance Package.

Four-wheel disc brakes are standard on all models – including Brembo four-piston calipers on SS – with hydraulic brake assist. StabiliTrak electronic stability control is standard on all models. Competitive/sport mode on SS models enhances on-track performance and Performance Launch Control on SS models with the manual transmission optimizes hard-acceleration launches for quicker, more consistent performance.

New for 2013, an electric power steering system developed for the ZL1 is standard on all SS. This variable ratio, variable effort system provides light efforts for easy maneuverability at parking-lot speeds as well as increased resistance at higher speeds, providing more feedback and a more direct steering feel.

Camaro safety and crash-avoidance features

The Camaro is designed to help drivers avoid crashes, while protecting occupants in the event a crash occurs. A strong body structure is designed to absorb crash energy and provide a protective “safety cage” around occupants. In fact, the 2012 Camaro was the first passenger car to receive NHTSA’s revised quadruple 5-star safety rating.

Additional features include:

• Six standard air bags include side curtain air bags, which provide head protection for outboard passengers in the event of a side-impact or rollover crash
• Rear Vision Package includes a rearview camera system to complement the rear park assist feature (standard on 2LT and 2SS; available on 1LT and 1SS)
• StabiliTrak electronic stability control system helps reduce the risk of rollover crashes by keeping the vehicle in the driver’s intended path by applying throttle, braking or a combination of both
• Standard four-wheel disc brake system featuring smooth, quiet operation, longer pad life and more resistance to brake pulsation
• Pretensioners minimize forward movement during a collision, and are standard on the front safety belts. Load-limiting retractors cinch the belt more tightly
• Standard tire pressure monitoring system
• Standard remote keyless entry (RKE) system provides a second function for the red panic button. Drivers can use it to locate their cars without sounding the panic alarm.

OnStar details

Six months of OnStar Directions and Connections service is standard on all Camaro models. OnStar is the global leading provider of connected safety, security and mobility solutions and advanced information technology.

OnStar’s RemoteLink Mobile App allows smartphone users to control vehicle functions, access vehicle information and send directions directly to the vehicle. A new, opt-in service called FamilyLink allows subscribers to stay connected to loved ones by checking the location of their vehicle online or by signing up for vehicle location alerts.

Camaro also features new OnStar button icons. Drivers will notice an updated look for the Hands-Free Calling button, blue OnStar button and red Emergency button.

Chevrolet today introduced the restyled 2014 Camaro line at the New York Auto Show, including the return of the Z/28, the most iconic model in Camaro history.

The 2014 Camaro models feature a revised exterior design that integrates high-performance aerodynamics for more efficient cooling and stability at high speeds. The new Camaro Z/28 also features a full aerodynamics package that creates downforce at speed, which helps make it the most track-capable offering in Camaro’s history.

“As the ultimate track-capable Camaro, this car restores the mission of the original Z/28, and serves as a testament to the expertise of Chevrolet as the best-selling brand of performance cars,” said Mark Reuss, president, GM North America. “The build sheet is the wish list of any racer: lightweight, high-revving, dry-sump LS7 engine; carbon-ceramic brakes; integrated coolers for track use; true aerodynamic downforce, and a significant reduction in curb weight. This car could only come from Chevrolet, and could only be called the Z/28.”

The first Camaro Z/28 was introduced in 1967, created to compete in the Sports Car Club of America's Trans-Am 2 class. It featured a smaller, lighter, 302-cubic-inch V-8 for improved weight balance, as well as quick-ratio steering and a heavy-duty suspension for track use. In keeping with its road-racing focus, the 1967 Camaro Z/28 was not available with an automatic transmission or air conditioning.

While the new Camaro Z/28 is not intended to compete in a specific race series, it is solely focused on track capability. In initial testing, the Camaro Z/28 is three seconds faster per lap than the Camaro ZL1. That extra speed comes from three areas:

Increased grip: The Z/28 is capable of 1.05 g in cornering acceleration, due to comprehensive chassis revisions
Increased stopping power: the Z/28 features Brembo carbon-ceramic brakes capable of 1.5 g in deceleration, and consistent brake feel, lap after lap
Reduced curb weight: The naturally aspirated Z/28 weighs 300 pounds less than the supercharged Camaro ZL1, with changes ranging from lightweight wheels to thinner rear-window glass

Like the original, the 2014 Camaro Z/28 is offered only with a manual transmission. In a nod to modern convenience, air-conditioning is available, but only as an option.

"We set out to make the fastest road-racing Camaro possible that was still street-legal,” said Al Oppenheiser, Camaro chief engineer. “While the Camaro ZL1 offers exceptional performance on the street, the drag strip, and the track, the Z/28 is entirely focused on the track performance. The Z/28 will be too track-focused for most drivers, but offers road-racers one of the most capable track cars ever offered from an automaker.”

The new 2014 Camaro line will arrive at Chevrolet dealers later in 2013. The Camaro Z/28 is expected to be appearing at track events across the United States in spring 2014.

High-performance aerodynamics highlight changes for 2014 Camaro

The 2014 Camaro represents the most significant redesign since the introduction of the fifth-generation Camaro as a concept car in 2006.

“The 2014 Camaro is our opportunity to apply what we have learned listening to our customers, and our continuing development of high-performance models,” said Tom Peters, Camaro exterior design director. “We look for solutions that are both functional and beautiful so that the result is genuine Chevrolet – simple, powerful, honest, and more than expected.”

Compared to the previous model, the design represents a strong visual change front and rear, resulting in a wider, lower, more contemporary appearance. The front fascia features a wider lower opening, and a narrower upper opening that also updates the appearance of the iconic “halo ring” HID headlamps on the Camaro RS package. The functional hood vent on the Camaro SS helps reduce heat and aerodynamic lift. Moving to the rear, the sculptural decklid, horizontal lamps and diffuser complete the powerful statement.

The Camaro Z/28 also features a full aerodynamic package designed to produce downforce at track speeds. At the front, the Z/28 features a large splitter, connected to an underbody panel that further reduces lift. In profile, the Z/28 features fender flares over the front and rear wheels, as well as extended rocker panels that contribute to aerodynamic stability. An aggressive rear spoiler and functional diffuser complete the aerodynamic package.

On the interior, the Camaro Z/28 features trim in a distinctive, matte-metallic finish named Octane, the ZL1 flat-bottomed steering wheel, and standard Recaro seats with microfiber suede inserts. The new seats (also available on the coupe versions of the SS and ZL1 models), feature aggressive bolsters for high-performance driving, as well as seat cutouts inspired by the five-point harnesses found on racing seats. To save weight, both front seats incorporate manual adjustment.

The rear seats of the Z/28 have also been modified for weight reduction. A total of nine pounds (four kilograms) was saved by eliminating the seat-back pass through, as well as using high-density foam in place of the rigid structure of the seat back and steel mesh of the seat bottom.

“Unlike the Ford Mustang Boss 302, we felt it was important to keep the 2+2 configuration of the Camaro Z/28 as Chevrolet already has a world-class two-seat sports car in the Corvette,” said Oppenheiser. “By modifying the construction of the rear seat, we were able to reduce the overall weight of the Z/28 while still preserving the flexibility of 2+2 seating.”

7.0L, LS7 the heart of the Camaro Z/28’s track-capable performance

Like the original, the new Camaro Z/28 forgoes ultimate horsepower and torque for improved weight balance and track performance.

In 1967, the most-powerful engine available in a factory Camaro was a 396 cid V-8 with 375 horsepower. To prepare the Camaro Z/28 for road racing, engineers specified a lighter, 302 cid V-8, officially rated at 290 horsepower. While the 302 was not the choice for drag racers, it proved ideal for sports-car racing.

Today, the most-powerful engine offered is the Camaro ZL1’s supercharged 6.2L LSA, which delivers 580 horsepower. The heart of the 2014 Camaro Z/28 is the lighter, naturally aspirated 7.0L LS7 first introduced in the Corvette Z06.

“The LS7 is ideal for road racing because it delivers amazing performance in a compact, lightweight package,” said Jordan Lee, Small Block chief engineer and program manager. “The broad torque curve and high redline of the LS7 mean fewer shifts are required for each lap, while the lightweight design improves the front-to-rear weight balance for better handling.”

Co-developed with Corvette Racing, the hand-assembled 7.0L (427 cid) V-8 uses a number of high-performance components, including:

Titanium intake valves and connecting rods, and sodium-filled exhaust valves
CNC-ported aluminum cylinder heads
Forged-steel crankshaft and main bearing caps
High-lift camshaft
Hydroformed exhaust headers
11.0:1 compression ratio, and a 7,000 rpm redline.
10.5-quart, dry-sump oiling system

For the Camaro Z/28, the LS7 features unique induction and exhaust systems, and delivers at least 500 horsepower (373 kW) and 470 lb-ft of torque (637 Nm).

The racing-style, cold-air induction system and large K&N air filter provide maximum air flow.

The standard dual mode exhaust system and larger-diameter pipes enable improved air flow. By bypassing the mufflers during acceleration, the system increases both the torque and sound generated by the LS7 engine.

The Camaro Z/28 is exclusively offered with a Tremec TR6060 manual transmission. The six-speed features close-ratio gearing and 3.91:1 final drive ratio, both optimized for the power characteristics of the LS7.

Power is distributed to the rear wheels via a limited-slip differential featuring a helical gear set, rather than traditional clutch packs. The new design enables the driver to apply more power and get through corners faster, by continuously adjusting the torque bias to maximize available traction.

The differential works in unison with Chevrolet’s proprietary Performance Traction Management system, which allows drivers to adjust the level of throttle and brake intervention to match their capability and driving environment.

Unlike some competitors’ “track package” offerings, the Camaro Z/28 makes standard all the cooling systems required for track use. This includes the dry-sump oiling system for the LS7, which is connected to an integral liquid-to-liquid cooling system for engine oil.

A second liquid-to-liquid system provides cooling for the transmission and differential. This system pumps overcooled transmission fluid to a heat exchanger in the rear differential before traveling to the transmission. This reduces differential temperatures as much as 100 degrees F.

Camaro Z/28 chassis delivers 1.05 g in cornering grip

The singular focus of the Camaro Z/28 is most evident in the chassis, where the most has been made of every component for track use, from the ultra-high performance tires to race-proven dampers.

“We used the very best components in the industry to deliver uncompromised performance, lap after lap,” said Mark Stielow, Camaro Z/28 engineering manager. “We made nearly 200 changes to improve the track performance, which cumulatively make the Z/28 capable of 1.05 g in cornering. For perspective, with all other things, equal increasing maximum grip from 1 to 1.05 g can cut up to four seconds per lap.”

The Camaro Z/28 is the one of the first production cars fitted with race-proven, spool-valve dampers. Compared to a conventional damper that offers only two-way tuning for bump and rebound, a spool-valve damper allows four-way adjustment to precisely tune both bump and rebound settings for high-speed and low-speed wheel motions. The wider tuning range allowed engineers to dramatically increase the damper stiffness on the Camaro Z/28 without a significant change in ride quality. Additional chassis changes include stiffer string rates and suspension bushings for improved cornering response.

The Camaro Z/28 features 19-inch diameter wheels and tires, which reduce unsprung weight by 42 pounds (19 kilograms) per car compared to the 20-inch wheels standard on Camaro SS and ZL1. In addition, the smaller diameter wheels lower the center of gravity by 33 millimeters, further improving handling.

At all four corners, the lightweight, forged aluminum wheels are wrapped in massive 305/30ZR19 tires. This is the first production application of ultra-high performance Pirelli PZero Trofeo R tires, and believed to be the widest front tire on any production car.

To fully exploit the grip of the Pirelli tires, the Camaro Z/28 also features Brembo Carbon Ceramic Matrix™ rotors and fixed, monoblock calipers. The large 394 x 36 mm front rotors are paired with six-piston calipers, while the 390 x 32 mm rear rotors are paired four-piston calipers. Compared to similar-size, two-piece steel rotors, the lightweight carbon discs save 28 pounds (12.5 kilograms) per car.

The combination of tire grip and braking power enable the Camaro Z/28 to achieve up to 1.5 g in deceleration. With standard front brake cooling ducts, the Z/28 is also capable of continuous track use unmatched brake feel, lap after lap.

“What makes the Z/28 so addictive is it inspires confidence through every section on the track,” said Stielow. “The incredible, balanced performance helps you carry much more speed through every corner: the brakes are so good you can adjust your braking points later and later; the grip and suspension damping allows you to carry more speed through the apex; and then the limited slip allows you to make the most of the LS7 as you power out of the corner.”

Extensive lightweighting saved 300 pounds over the Camaro ZL1

To optimize the track performance of the Camaro Z/28, the engineering team subjected it to an intensive lightweighting program, saving 100 pounds (45 kilograms) compared to the naturally aspirated Camaro SS and 300 pounds (136 kilograms) to the supercharged Camaro ZL1.

“We looked at every subsystem for opportunities to save weight,” said Oppenheiser. “Our goal was to get rid of everything that didn’t make the car faster, and keep only what was required by law. For example, we wanted to eliminate the audio system completely, but we had to keep a single speaker for the seat-belt chime to meet safety requirements.”

Other examples of weight savings include:
Eliminated the tire-inflator kit, except for Rhode Island and New Hampshire, where it is required by law
Removed interior sound deadener, and carpeting from the trunk
Replaced the standard LN4 battery with a smaller, lightweight, LN3 battery
Specified thinner, 3.2-mm glass for the rear window, compared to 3.5-mm glass on the standard Camaro
HID headlamps and foglights are not available
Air conditioning is only available as a stand-alone option

“The team was so fanatical about saving weight, we even stripped the unused wiring out of the harness when we eliminated the fog lights, speakers, and air conditioning,” said Oppenheiser. “Every ounce saved contributed to making this the most track-capable Camaro we have ever built, and a worthy successor to the Z/28 name.”
