Audi is turning the Wörthersee 2013 into the “Home of quattro”. At the large gathering from May 8 to 11 in Reifnitz (Kärnten), the premium brand will unveil the Audi TT ultra quattro concept – which combines minimal weight and maximum sportiness. A wide range of high-performance cars will also give fans another taste of sportiness. In addition to the legendary Sport quattro S1, the very latest RS models and thoroughbred race cars are also on show. The Audi R18 e-tron quattro, which was the first hybrid car to win the 24 Hours of Le Mans last year, will also be part of the action at the lakeside.

At the start of May every year, the Wörthersee is the place to be for every car and Audi aficionado. Audi will therefore be showcasing a special highlight in 2013: the Audi TT ultra quattro concept. The showcar combines a lean 1,111 kilograms (2,449.34 lb) total weight with a 2.0 TFSI engine, whose 228 kW (310 hp) and 400 Nm effortlessly propel the coupé. From a standstill the TT ultra quattro concept is catapulted in 4.2 seconds to 100 km/h (62.14 mph). Its power-to-weight ratio of 3.6 kg/hp is on a par with thoroughbred super sports cars. And it is also worthwhile looking at the detail, not least because the concept car pays homage to automotive lightweight construction.

Even the current series-production car with a body weight of just 206 kilograms (454.15 lb) plus 98 kilograms (216.05 lb) for the detachable body parts is testimony to the outstanding lightweight construction expertise of Audi. The engineers from Ingolstadt and Neckarsulm concertedly fine-tuned the Audi Space Frame (ASF) in the current TT generation to come up with the body for the Wörthersee showcar, shedding another 43 kilograms (94.80 lb) from the body structure. Together with the optimized detachable body parts, the result is a weight saving of 100 kilograms (220.46 lb).

Audi has adopted an intelligent mix of materials according to the motto: the right amount of the right material in the right place. The Audi TT ultra quattro concept uses carbon-fiber reinforced polymer (CFRP) in the rear end, the center tunnel, in the B-pillars and in the roof. Magnesium components in the floor and as hinge reinforcement reduce weight even further.

The combination of lightness and sportiness is also reflected in the looks. Compared with the series-production model, the Audi designers have substantially honed the showcar’s contours even further. With its large spoilers, the TT ultra quattro concept proudly displays its motorsport genes. The base of the rear wing is manufactured as a supporting component from milled aluminum, while the wing, as a functional element, is made of visible carbon.

The concept car is painted in the special color crystal white. The CFRP used on the exterior adds a striking touch on the hood, the roof, the sides and the trunk. In the interior the same material also adorns the door trim, the center console and the cross-bracing that replaces the rear seat bench. The developers have also fitted the bucket seats from the R8 GT to the concept study; their chassis alone, made out of fiberglass-reinforced plastic (FRP), reduce weight by 22 kilograms (48.50 lb). The driver does not have to make any compromises when it comes to equipment and appointments: air conditioning, electric window controls and an electromechanical parking brake come as standard on the TT ultra quattro concept. A veritable highlight: the exterior mirrors are replaced by compact cameras which transfer the images directly into the digital cockpit.

To reverse the weight spiral, the Audi ultra lightweight construction concept is applied to all elements in the automobile. The developers have further optimized each component. The front brakes feature ceramic discs with an aluminum fixed caliper, the exhaust system made out of titanium ends in a single central tailpipe. The wheels also reduce weight by 20 kilograms (44.09 lb). Spokes made out of high-strength aluminum are bolted directly to the CFRP wheel.

Every gram counts, particularly on the suspension. Here the unsprung masses have been reduced, thus improving comfort and handling. On the TT ultra quattro concept the coil springs are not made out of steel but from fiberglass-reinforced plastic (FRP). The core of the all-new springs consists of long glass fibers twisted together and impregnated with epoxy resin. A machine wraps additional fibers around this core, which is only a few millimeters in diameter, at alternating angles of plus and minus 45 degrees to the longitudinal axis. These layers support each other and act in either compression or tension. The use of FRP at this point cuts weight by 40 percent while maintaining good characteristics – 6 kilograms (13.23 lb) in relation to the car as a whole.

To further hone the handling of the TT, the developers have taken away weight from the ends of the car and moved it into the middle. The lithium-ion starter battery, for instance, is located in the interior under the driver’s seat. It is much smaller than a lead battery and weighs as little as just under four kilograms (8.82 lb).

Overall, all these lightweight construction measures make the concept car about 300 kilograms (661.39 lb) lighter than the comparable sporty series-production model. All of which helps minimize the inertial mass that the 228 kW (310 hp) 2.0-liter TFSI engine contends with during acceleration. The modified high-end four-cylinder unit develops its maximum torque of 400 Nm between 1,900 and 5,000 rpm, putting it on a par with the power of the V8. Modifications to the crankcase, the crankshaft, the balancer shafts, the flywheel, the oil sump, the bolts and certain ancillary units that make the engine 25 kilograms (55.12 lb) lighter have all helped get the engine into tip-top shape.

Thus the Audi TT ultra quattro concept offers the kind of driving experience that automotive fans on the Wörthersee expect from a genuine high-performance model. Like the “Ur-quattro” from 1980 and more than five million series-production vehicles since, this year’s showcar is also fitted with the quattro permanent all-wheel drive. Grip is therefore always ensured despite the impressive performance. With its six speed transmission, the TT ultra quattro concept is 1.3 seconds faster than the series-production model when accelerating from 0 to 100 km/h (62.14 mph). The top speed is 280 km/h (173.98 mph).

The Audi showcar demonstrates the technical possibilities of an intelligent mix of materials. In this way considerable weight savings can even be achieved on an existing series-production model. Usage of these technologies is conceivable for future small-batch series.

Audi has taken the somewhat unusual step of unveiling much of the interior of its upcoming TT Coupe at the 2014 Consumer Electronics Show in Las Vegas. That's unusual, because they haven't shown us the car yet. Perhaps we shouldn't be surprised – with the proliferation of technology in automobiles these days, it's probably time we start considering them as much electronic devices as transportation devices.

While Audi has long been recognized as a leader in interior design, this new TT features an instrument cluster that is wildly different from what we've become accustomed to from the Four-Ring brand. Audi is calling its fully digital system a "virtual cockpit," and with its 12.3-inch LCD screen situated directly in front of the driver, it does away with the company's traditional Multi-Media Interface (MMI) display in the center stack. Two modes are offered, one classic option with large gauges and another more oriented to infotainment.

Besides electronics, the actual hard parts of the interior also show plenty of new thinking. With the removal of the central screen, Audi has been able to streamline its instrument panel to resemble a wing of sorts, with jet-like HVAC vents that house their own controls. Two more points for controls are presented to the driver, with buttons on the flat-bottom steering wheel and another set on the center tunnel.

The Audi TT offroad concept breaks the mold, combining the sportiness of a coupe with the lifestyle and utility of a compact SUV. The four-door model, which Audi is presenting at the Beijing International Automobile Exhibition, adds an entirely new expression to the Audi design language. Its plug-in hybrid drive with two electric motors and a system output of 300 kW (408 hp) provides for dynamic performance, yet consumes on average just 1.9 liters of fuel per 100 kilometers (123.8 US mpg).

“The Audi TT offroad concept provides a glimpse of how we might imagine a new model in the future TT family,” says Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development. “It combines the sporty genes of the TT with the strengths of a compact Audi SUV. Its plug-in hybrid drive with the option of inductive charging is a major step toward the mobility of the future. We chose to present the Audi TT offroad concept in China, our second domestic market, because it represents the urban mobility of tomorrow: It is sustainable, dynamic, intelligent and connected.”

The plug-in hybrid drive

The plug-in hybrid drive in the Audi TT offroad concept delivers 300 kW (408 hp) of system output and 650 Nm (479.2 lb-ft) of system torque. The show car accelerates from 0 to 100 km/h (62.1 mph) in 5.2 seconds and reaches the electronically governed top speed of 250 km/h (155.3 mph) without any trouble. It consumes just 1.9 liters of fuel per 100 kilometers (123.8 US mpg), a CO2 equivalent of 45 grams per kilometer (72.4 g/mile).
The Audi TT offroad concept can drive over 50 kilometers (31.1 miles) solely on electric power and thus with zero local emissions, and has a total range of up to 880 kilometers (546.8 miles).

The combustion engine is a 2.0 TFSI producing 215 kW (292 hp) and 380 Nm (280.3 lb-ft) of torque. The two-liter, four-cylinder unit with the large turbocharger is packed with Audi's potent efficiency technology. At part load, indirect injection supplements gasoline direct injection for lower fuel consumption. The exhaust manifold is integrated into the cylinder head – the foundation for the high-performance thermal management system.

A separating clutch links the transverse 2.0 TFSI to an electric motor producing 40 kW and 220 Nm (162.3 lb-ft) of torque. The slim, disc-shaped electric motor is integrated into the six-speed e-S tronic. The dual-clutch transmissions sends the torque to the front wheels. Mounted on the rear axle of the Audi TT offroad concept is a second electric motor independent of this drive unit. This produces a maximum of 85 kW and 270 Nm (199.1 lb-ft).

In front of the rear axle is a liquid-cooled, lithium-ion battery comprising eight modules. It contributes to the balanced 54:46 weight distribution between the front and rear axles and to the low center of gravity. The battery stores up to 12 kWh of energy, enough for an electric range of 50 kilometers (31.1 miles). An Audi wall box, which manages the energy feed conveniently and intelligently and can deal with a variety of voltages and outlets, is used for stationary charging.

The show car is also designed for use with Audi Wireless Charging technology for contactless inductive charging. The infrastructure side – a plate with a coil and an inverter (AC/AC converter) – is placed on the parking spot of the Audi TT offroad concept and connected to the power grid. The charging process begins automatically when the car drives onto the plate. The alternating magnetic field of the infrastructure side induces a 3.3 kW alternating current across the air gap in the secondary coil, which is integrated into the vehicle. The current is inverted and fed into the electrical system.

Charging stops automatically when the battery is fully charged. It takes about as long as charging via a cable, and the driver can interrupt the process at any time. The Audi Wireless Charging technology is more than 90 percent efficient, and is not affected by weather factors such as rain, snow or ice. The alternating field, which is only generated when a car is on the plate, is not harmful for people or animals.

The intelligent plug-in hybrid concept of the Audi TT offroad concept really shines when driving, making the show car every bit as efficient as it is sporty. The Audi drive select management system offers three driving modes. EV mode gives priority to electric driving. In this case, the front drive unit is inactive, and the electric motor at the rear axle with its powerful torque can rapidly accelerate the four-door car to a maximum of 130 km/h (80.8 mph). In Hybrid mode, all three drives work together in various ways as necessary. In many situations the front electric motor assumes the role of a generator.

Powered by the engine, it recharges the battery and thus extends the electric range. Full system output is available in Sport mode. During “boosting,” i.e. strong acceleration, the rear electric motor works together with the 2.0 TFSI. The same thing happens when the hybrid management system decides that all-wheel drive is appropriate. In such situations, e.g. on a slippery road or in light off-road conditions, this essentially makes the Audi TT offroad concept an e-tron quattro.

When the driver takes his or her foot off the accelerator, free-wheeling or “coasting” is activated. Recuperation occurs here at low speeds and when braking. The driver can use the “Hold” and “Charge” functions in the MMI system to specifically influence the battery's charge state, e.g. to increase storage of electric energy so that it can be used over the final kilometers to the destination.

Chassis

The Audi TT offroad concept shows its strong character on any road surface and in any terrain. On asphalt the show car is sporty and composed, and it can easily handle light terrain thanks to its high ground clearance, short overhangs and e-tron quattro all-wheel drive. 255/40-series tires are mounted on 21-inch wheels, whose delicate five-arm design draws on the look of the Audi e-tron models. Dark trim provides contrast.

Many of the components of the McPherson front suspension are made of aluminum; the four-link rear axle handles longitudinal and transverse forces separately. The ratio of the progressive steering changes with the steering input. The Audi drive select system allows the driver to modify the function of various technical modules in multiple steps.

Driver assistance systems

The Audi TT offroad concept show car features two Audi driver assistance systems that are almost ready for production: the intersection assistant and online traffic light information technology. The intersection assistant aims to help to avoid side-impact collisions, or reduce their severity, where lanes merge and at intersections. Radar sensors and a wide-angle video camera scan zones to the front and sides of the car. If the system detects a vehicle approaching from the side and assesses it to be critical, graduated warnings are displayed in the Audi virtual cockpit.

Online traffic light information is a technology that connects the Audi TT offroad concept via the cell phone network to the central traffic computer, which controls the traffic light systems in the city. Based on the information from this system, the Audi virtual cockpit shows the driver what speed to drive in order to reach the next traffic light while it is green. The cockpit displays the time remaining when waiting for the light to turn green.

Body

Like many of the brand's new production models, the Audi TT offroad concept is also based on the versatile modular transverse matrix (MQB). The body of the show car is based on the ASF (Audi Space Frame) principle and features a hybrid concept with both steel and aluminum components. Together with the battery package of the plug-in hybrid drive system, it gives the compact crossover a low center of gravity, which is a prerequisite for its sporty performance.

Exterior design

4.39 meters (16.2 ft) long, 1.85 meters (6.1 ft) wide and a wheelbase of 2.63 meters (8.6 ft) – in these dimensions the Audi TT offroad concept resembles today's compact SUV, the Audi Q3*. At 1.53 meters (5.0 ft) tall, however, it is 8 centimeters (3.2 in) shorter, making its sporty character obvious at first glance. The Sonora Yellow outer skin appears to have been modeled from a solid block; the interplay of the clearly drawn lines and the muscularly taut surfaces produces a highly dramatic design. It uses the design language of the Audi TT*, but places its elements in a new context.

Horizontal lines dominate at the front of the new Audi TT offroad concept. The broad Singleframe grille bearing the four rings is sculpturally embedded in the body. Two subtle indents in the lower region make the grille appear lighter. Narrow louvers in the grille insert form a structure typical of the Audi e-tron models.

The large air inlets below the Matrix LED headlights are framed in sharp edges and structured with louvers. A third, flat inlet below the grille joins them together. Inside is a blade that increases downforce on the front axle and makes the front of the Audi TT offroad concept appear even wider.

When viewed from the side, the relationship between the show car and the Audi TT* is even more apparent. The overhangs are short; the greenhouse is sportily low and drawn in sharply toward the top. The height ratio is 30:70. The window design follows the sporty coupe line. The roof contour drops down again early; fine light-refracting edges make the powerful, very flat C-pillars appear lighter.

The Audi TT offroad concept has a powerful, hunkered-down stance on the road. The broad semi-circles of the wheel wells form separate geometric bodies, sharply accentuating the massive wheels. The front wheel well intersects the joint of the engine hood, which runs above the door as a tornado line and continues to the rear of the car.

The inner arc segments of the wheel wells are painted in contrasting gray. Together with the bottom zone of the sill strips, which is also gray, they reduce the visual weight of the body and underscore the robust character of the show car. Adorned with a quattro logo, the sill itself forms a bold light-refracting edge.

At the rear, horizontal lines frame athletically taut surfaces. The offset bumper envelopes the two round tailpipes of the exhaust system. A blade with a quattro logo connects them and provides for visual width.

Interior

The interior of the Audi TT offroad concept offers space for four. The rear seat can accommodate two adults comfortably. The slim sport seats with integrated head restraints ensure lateral hold. The side bolsters of the front seats are very strongly contoured.

The design ideas of the new TT were also the inspiration for the sporty interior of the show car. The top of the instrument panel is designed as a wing. This is supported by a visible aluminum structure that as a horizontal design element incorporates the air vents and underscores the width of the interior. The round air vents are reminiscent of jet engines and incorporate the air conditioning controls. The slender instrument panel is focused on the driver.

Besides elements from the TT*, the design of the center console and the doors of the show car also include numerous elements from the Q family, such as a robustly designed tunnel support and functional cup holders in front of the shift lever.

A large number of functions can be controlled via the multifunction steering wheel or the MMI terminal on the center tunnel console. The menu structure is oriented on a smart phone, with all key functions easy to reach. The driver can use finger gestures on the touchpad of the MMI terminal to zoom or scroll in lists and maps. All other functions can be easily controlled via the multifunction steering wheel without having to look away from the road.

Serving as the display instrument is the Audi virtual cockpit. The 12.3-inch TFT display produces high-quality 3D graphics. The driver can customize the display with the push of a button. The classic view is dominated by the speedometer and the power meter for the plug-in hybrid drive. In Infotainment mode, elements such as the navigation map or online traffic information displays take center stage. The Audi virtual cockpit also displays detailed information on charging with the Audi Wireless Charging technology.

The center tunnel console, which extends all the way to the back seat, contains numerous cup holders and storage bins. One of these is reserved for the Audi phone box, which connects the driver's cell phone to the on-board electronics and also charges it inductively, when necessary.

The show car's ventilation system also includes an ionizer – an updated version of the system used in the A6* and the A8*. Ionization significantly improves the quality of the air in the cabin. The standard cabin air filters also remove particulates from the air and are unmatched by the immediate competition. Thanks to the systematic further development of these filters, even allergens will be neutralized in the future. An LED light in the interior of the air vent lights up when the ionizer is turned on.

The show car is equipped with three Audi Smart Displays. The fast tablets serve as a mobile infotainment system for use inside and outside of the car. From DVD or TV streaming to controlling the radio or navigation planning, the Audi Smart Display is extremely versatile. One click on the “more” button in the start menu establishes an Internet connection via Audi connect at LTE speed. The user now has access to all of the functions of the Android operating system, from browsing with Google Chrome to visiting the Google Play store.

The Audi Smart Display was systematically developed for use in cars and can easily withstand even extreme temperatures. Rear seat passengers can place the display in special mountings on the backs of the front seats. All three displays can be used simultaneously. When not using the displays, passengers in the rear seat can stow them in a specially designed slot between the seats, where the displays are also recharged. The front seat passenger can store the display in the glove compartment.

Two loudspeakers for the Bang & Olufsen Advanced Sound System are installed in the head restraints of the individual seats. They provide for optimal surround sound throughout the cabin to create a special sound experience. The head restraint speakers are also used for voice announcements and telephony. This guarantees extraordinarily good sound quality and outstanding speech transmission even during fast, sporty driving.
A custom-designed box in the trunk contains a 1:8-scale radio-controlled (RC) car. There is also space for the battery and tools. The power-folding individual rear seats allow for a nearly flat cargo floor.

In keeping with the sporty character of the show car, the interior features fine materials and a combination of light and dark gray tones. Granite Gray Fine Nappa leather is used on the rim of the steering wheel and in the outer zones of the door liners. The headliner, the pillar covers, the door panels and the center tunnel are covered with matching Alcantara. The door armrests, the center tunnel console and the seats with diamond-patterned stitching are covered in very soft, luxurious Stone Gray leather from the Italian company Poltrona Frau.

A completely revised edition of a modern classic is ready to take center stage: The Audi TT and Audi TTS will celebrate their world premieres at the Geneva Motor Show (these vehicle are currently not available for sale. they do not yet have a general type approval and are therefore not covered by Directive 1999/94/EC.). The third generation of the compact sports car is again captivating, with its emotional design and dynamic qualities. The new Coupé is characterized by the use of innovative technologies in its engine and in its control and display concept, including the Audi virtual cockpit.
“The Audi TT is the epitome of an authentic design icon and a top-performance driving machine,” explains Prof. Dr. Ulrich Hackenberg, Member of the Board of Management of AUDI AG for Technical Development. “With the new generation, we are making this technology even easier for the driver to experience – just as they would expect from a real sports car.”

Exterior design

When the first-generation Audi TT came on the market in 1998 it was a design revolution – its strictly geometrical, formally coherent design language made it an icon with huge charisma. For the third TT generation, the Audi designers have returned to many of these ideas and placed them in a new context that is as dynamic as it is diverse.

The front of the new TT is dominated by horizontal lines. The Singleframe grille is much broader and flatter than that of the previous model, with a powerful line dividing it into two zones. Starting in the top corners of the grille, sharp contours run in a V across the hood, which bears the four Audi rings – as on the Audi R8 high-performance sports car (combined fuel consumption in l/100 km: 14.9 – 12.4 (15.79 – 18.97 US mpg); combined CO2 emissions in g/km: 349 – 289 (561.66 – 465.10 g/mile). The air intakes feature struts that direct part of the flow away from the front to the flanks.

The flat headlights give the new TT’s face a determined look. Xenon plus units are standard, and Audi can optionally provide LED headlights or ones in pioneering Audi Matrix LED technology, where the high beam is generated by controllable individual LEDs. On both versions, there is an unmistakable contour created by the separating strip in the headlights, which is illuminated by light guides.

The Matrix LED headlights consist of 12 LEDs and include another Audi innovation: dynamic turn signals that light up sequentially in the direction in which the driver is steering. The predictive cornering light uses navigation data to move the cone of light into the curve before the steering wheel is turned.

From the side, the new Audi TT is equally lean and muscular; it rests low on the road as if ready to pounce. At 4.18 meters (13.71 feet), the Coupé is almost exactly the same length as its predecessor, though its wheelbase has grown by 37 mm (1.46 in) to 2,505 mm (8.22 ft), making for especially short overhangs. It is 1,832 mm (6.01 ft) wide, and has the same height as the previous model at 1,353 mm (4.44 ft).

A lot of the details of the new Audi TT’s profile are reminiscent of the first-generation of the modern classic. The contour of the sill creates a striking refracting edge, while the broad wheel arches form their own geometric bodies. The front wheel arch breaches the line of the hood, which continues over the door as a tornado line and runs almost horizontally through to the tail as a strong body shoulder.

The flat greenhouse gives the impression of being an independent unit and the slight kink in the rear side window gives it additional tension. The fuel flap on the right side panel is the classic circle and surrounded by socket screws; a light tap on the TT logo and the flap opens. This shape is again reminiscent of the first-generation TT. What is new is that there is no tank lid beneath the flap. This means that there is nothing to be unscrewed and the pump nozzle slots straight into the tank neck, just like in motor racing.

Specifically at the tail, horizontal lines underline the impression of the new TT’s sporty width. Together with the LED and Audi Matrix LED headlights, the tail lights also have dynamic turn signals. Another parallel to the front headlights: the strip in the tail lights, which also form a daytime running light contour – another Audi innovation. The third brake light is an extremely narrow strip positioned under the edge of the rear spoiler. It plays an essential part in defining the tail light silhouette.

At a speed of 120 km/h (74.56 mph) a spoiler extends from the trunk lid to improve both air resistance and downforce. All models have two large round exhaust tailpipes. These are again reminiscent of the original TT. Like all Audi S models, the TTS exhales through four oval tailpipes.
The optional S line exterior package makes the design of the bumpers, air intakes, Singleframe grille, sills and the rear diffuser even sharper and sportier. And handling is even more dynamic, with 18” wheels and a body that rests 10 mm (0.39 in) lower.

Body

Lightweight construction is one of Audi’s greatest areas of expertise. The second-generation Audi TT already featured an Audi Space Frame (ASF) body made from aluminum and steel. For the new TT, Audi has systematically taken this composite construction principle even further, in line with the idea: the right amount of the right material in the right place for optimal functions.

The Coupé’s underbody structure has optimized axle loads and is made of modern, high-strength and ultra-high-strength steel alloys. In the sections of the passenger cell that are subject to the most structural stress, form-hardened steel panels, which are both ultra-high-strength and light are used – these constitute 17 percent of the body’s weight. The side sills and roof frame are made of extruded aluminum profiles that are integrated into the structure using cast aluminum nodes. This structural principle creates a very rigid and safe bodyshell. The aluminum side sections and roof complete the structure. The hood, doors and trunk lid are also made of this light metal.

All in all, the Audi engineers have, for the second time in a row, succeeded in significantly reducing the unladen weight of the Audi TT. At the first model change in 2006, up to 90 kg (198.42 lb) were saved, and the 2.0 TFSI engine variant of the new TT weighs just 1,230 kg (2,711.69 lb). This makes it around 50 kg (110.23 lb) lighter than its predecessor.

The low overall weight is further proof of Audi’s expertise in lightweight construction. It impacts positively especially on acceleration, handling and fuel consumption.

Interior

Clearly structured volumes with a taut surface and light, almost floating lines – the interior is the embodiment of the new Audi TT’s pure sports car character. As with the exterior, horizontal lines and surfaces emphasize the width of the interior. The center tunnel console, which supports the calves when driving fast through bends, and the door panels have similar flowing shapes.

The rule was once again: “less is more.” Clear, purist lines underscore both the lightness and the uncompromising sportiness of the Audi TT’s interior. Two other ingenious design and technically innovative tricks enabled the designers to create an instrument panel that is impressively slender: The instrument cluster and the MMI screen have been combined to form a central, digital unit – the so-called Audi virtual cockpit. In addition, the controls for the air conditioning system are positioned directly in the air vents.

Seen from above, the instrument panel resembles the wing of an aircraft; the round air vents – a classic TT feature – are reminiscent of jet engines with their turbine-like design. The vents also contain all the controls for the standard air conditioning system and the optional automatic air conditioning system (standard in the TTS). The controls for seat heating, temperature, direction, air distribution and air flow strength are located at their center; the setting selected is shown on small displays in the automatic air conditioning system. The horizontal control panel is located under the central air vents. The 3D-designed toggle switches activate the hazard warning lights, Audi drive select and the assistance functions.

The standard sports seats in the new Audi TT have integrated head restraints and are positioned lower than in the predecessor model. Compared with the seats in the predecessor model, they are more than five kilograms (11.02 lb) lighter. As an option – and as standard in the TTS – there are newly developed S sport seats with highly contoured and pneumatically adjustable side sections that are exceptionally comfortable and provide excellent support.

The new multifunction steering wheel has a flattened rim, and aluminum-look clasps encompass the spokes. It also has a driver airbag that takes up 40 percent less space without compromising safety, and hence emphasizes the sense of visual lightness.

Countless details demonstrate the high standards which Audi places on interior design and craftsmanship. They include the newly designed, split gear lever, the very precisely engaging MMI rotary pushbutton and the finely finished loudspeaker covers with light guides in the optional Bang & Olufsen sound system.

As a 2+2 seater, the new Audi TT is a sports car that is highly suitable for everyday use. The trunk has a capacity of 305 liters (10.77 cubic feet), which is 13 liters (0.46 cubic feet) more than before, and can be extended by folding the rear seat backrests forward.

Colors and equipment

The new Audi TT offers a far more distinct and colorful range of colors than its predecessor. There are 11 exterior colors, one of which is exclusively for the S line. Seven of the colors in the range are new for the TT, and two of these are completely new for Audi: Nano Gray and Tango Red. There are also two additional paints available for the TTS – crystal-effect Panther Black and the highly expressive Sepang Blue.

There is a completely new range of colors for the interior, too – the Audi TT and the TTS each offer three interior colors to choose from. For the first time, Audi is offering a two-tone interior including sporty contrasting stitching for S line models.

The equipment for the new Audi TTS includes extended interior elements that add individually selectable color accents to the S sport seats clasps, the sides of the center console and the rings of the air vents. Customers with exquisite taste have many options for customization. Upholstery in various cloths and leather grades are available for the seats, as well as three leather packages. The S sport seats have characteristic diamond quilting in the center section.

One special highlight is the exclusive design selection which comprises a combination of two fine leather colors: dark murillo brown on the seats and a slightly metallic shimmering stone-grey pearl on the armrests, knee supports and cowl. Alternating contrasting stitching, dark aluminum, matching paint for the extended interior elements and a special woven floor mat are further features of this elegant upholstery and trim.

For the TTS, the Audi designers have come up with an innovative technical laser texture for the wings of the instrument panel: It has a honeycomb-patterned, slightly raised surface that gives the Audi TTS a unique sporty feel.

Controls and displays

The operating concept for the new TTS has been revised from the ground up – in line with the consistent sports car character, all the elements focus on the driver. There are two variants of the multifunction steering wheel available. Drivers selecting the top version can activate almost all functions from the steering wheel without taking their eyes off the road.

The second control unit is the likewise newly developed MMI terminal on the console of the center tunnel. Two toggle switches activate the navigation/map, telephone, radio and media menus. There are two buttons on both sides of the central rotary pushbutton, supplemented by a main menu and a back button. The driver can easily enter destinations using the touchpad on the top of the rotary pushbutton (from the Connectivity package upwards) – the MMI touch recognizes your personal handwriting. It is also possible to scroll through lists or zoom in on maps.

The menu structure of the MMI resembles that of a smartphone, including the free-text search. All important functions can be accessed directly. One special highlight is the MMI direct search. This enables you to start writing immediately when navigating, without having to use a set form. In most cases, inputting four letters is enough for you to see relevant destinations throughout Europe. The two side buttons activate context-dependent functions (right button) and options (left button). The operating logic is easy to understand and conveys a completely novel “joy of use.”

Alongside the operations possible using the control panel, the Audi TT offers a further possibility: the voice control system. Audi is also breaking new ground in this area, too. For the first time in the Audi TT, natural voice controls are used that enable simple commands – such as “Take me to Munich” or “I want to talk to Sabine” – to control the vehicle systems without having to take your hands off the steering wheel.

Instead of the conventional analog displays, the new TT has the Audi virtual cockpit on board – this fully digital instrument cluster sets new standards with its dynamic animations and precise graphics. Drivers can choose between two display modes: In the classic view, the speedometer and rev counter are in the foreground; in “infotainment” mode the virtual instruments are smaller. The space that becomes free as a result provides ample room for other functions, such as the navigation map. In the Audi TTS there is a third, sporty mode. Here, the centrally positioned rev counter dominates the display.

With a resolution of 1,440 x 540 pixels, the 12.3” TFT screen boasts brilliantly sharp images. At work in the background is a Tegra 30 graphic processor from market leader Nvidia’s Tegra 3 series. At the lower edge of the Audi virtual cockpit, the displays for outside temperature, time and mileage are permanently visible. Warning or information symbols may also appear there.

Engine

(All consumption and output figures are provisional) Audi offers the new TT and TTS with three different four-cylinder engines with turbocharging and direct injection. Their power output ranges from 135 kW (184 hp) to 228 kW (310 hp). The two TFSI gasoline engines and the TDI combine athletic power with trailblazing efficiency. The start-stop system is a standard feature.
For the launch of the TT, the 2.0 TDI will be available with manual shift and front-wheel drive. It delivers 135 kW (184 hp) and torque of 380 Nm (280.27 lb-ft). The new sports car can thus accelerate from 0 to 100 km/h (62.14 mph) in 7.2 seconds and reaches a top speed of 235 km/h (146.02 mph). Standard fuel consumption is a mere 4.2 liters per 100 km (56.00 US mpg), which translates into CO2 emissions of 110 g/km (177.03 g/mile), a new record low level in the sports car world.

The 2.0 TDI features two balancer shafts in the crankcase, adjustable camshafts and a common rail injection system delivering maximum pressure of 2,000 bar. The Audi TT 2.0 TDI meets the Euro 6 standard and, thanks to its high efficiency, bears the “ultra” label.

The 2.0 TFSI is available in two versions – a 169 kW (230 hp) version for the TT and a 228 kW (310 hp) version for the TTS. In both versions it unites various ultramodern technologies – the additional indirect injection supplementing the direct injection of the FSI, the Audi valvelift system (AVS) to adjust the valve stroke on the exhaust side and thermal management, which uses a rotary valve module and an exhaust manifold integrated into the cylinder head.

In the Audi TT, the 2.0 TFSI delivers torque of 370 Nm (272.90 lb-ft) from 1,600 to 4,300 rpm. It accelerates the Coupé – which has a six-speed manual transmission and front-wheel drive – from 0 to 100 km/h (62.14 mph) in 6.0 seconds, and on up to an electronically governed top speed of 250 km/h (155.34 mph).

On the version with six-speed S tronic and quattro all-wheel drive, the key figures are as follows: the sprint from 0 to 100 km/h (62.14 mph) takes 5.3 seconds; top speed is 250 km/h (155.34 mph); fuel consumption of 6.8 liters per 100 km (34.59 US mpg) and CO2 emissions of 159 g per km (255.89 g/mile). The dual-clutch transmission shifts through the six gears without any noticeable interruption in traction, and in manual model it can be controlled by paddles on the steering wheel. In the “efficiency” mode of Audi drive select, the S tronic selects freewheel as soon as the driver takes his or her foot off the gas pedal.

The Audi TTS is a peak performer. It covers the standard sprint in 4.7 seconds; its top speed is electronically governed at 250 km/h (155.34 mph). The 2.0 TFSI produces 380 Nm (280.27 lb-ft) of torque at an engine speed of between 1,800 and 5,700 rpm. Controllable flaps in the exhaust system modulate the sporty sound and make it even richer. A manual transmission is standard. The S tronic option includes launch control, which regulates maximum acceleration from a standstill.
quattro drive

In the new Audi TT, quattro permanent all-wheel drive delivers additional stability, traction and driving fun. It has been consistently advanced and optimized especially for the new TT. Its electro-hydraulically controlled multi-plate clutch is mounted on the rear axle. The special pump design reduces weight by around 1.5 kg (3.31 lb) compared with the previous model. The distribution of drive torque between the axles is controlled electronically within fractions of a second.

The intelligence of quattro drive – in other words, the software that determines precisely the possible torque distribution between the front and rear axles – is a completely new development especially for the TT. The innovative control philosophy continuously senses the ambient conditions, driving status and the driver’s wishes. This means that the ideal distribution of torque is calculated and the TT’s dynamic drive characteristics enhanced in every situation.

By networking quattro drive with Audi drive select, the driver of the new Audi TT can adjust the all-wheel-drive properties to suit his or her individual requirements. In “auto” mode, this produces optimum traction and balanced driving dynamics. In “dynamic” mode, torque is distributed to the rear axle earlier and to a higher degree, which means that driving dynamics are enhanced further, especially on surfaces with low friction coefficients.

Alongside optimizing the driving dynamics, the advances made to quattro drive also focused on the subject of efficiency. In the drive select “efficiency” mode the torque distribution is adjusted to optimize the level of efficiency. Determining driving conditions and driver type precisely allows for efficiency-optimized all-wheel-drive control – which can even result in the temporary shutdown of the quattro drive system. In this operating state, the intelligent software carefully monitors the driving situation and activates the all-wheel drive before torque is once again required at all four wheels. In this way, quattro drive provides optimum efficiency along with a level of traction and dynamic handling that is typically quattro.

Chassis

The chassis also reflects the technological expertise behind the new Audi TT. The front suspension is based on a McPherson system; aluminum components reduce the weight of the unsprung chassis masses. The four-link rear suspension can process the longitudinal and transverse forces separately.

One particular highlight is the new third generation of the adaptive damper control system, Audi magnetic ride. Compared with the previous version, it has been improved in terms of characteristic spread, control dynamics and precision as well as user friendliness. Audi magnetic ride can be adjusted to three settings (comfort – auto – dynamic) via Audi drive select and, at the press of a button, either makes the compact sports car hug the road more tightly or lets it glide smoothly across the road irrespective of which mode the driver selects. Magnetic ride technology delivers ultra-swift wheel-selective control of the damper forces, which means that in all driving situations there is optimum contact between wheel and road.

In this way, the new Audi TT’s superb driving dynamics are further optimized, and body control also ensures good comfort behavior. The system is unique in this market segment. Audi magnetic ride is standard on the Audi TTS and is available as an option for all other TT versions.

Another highlight is the standard progressive steering – its rack is designed such that the ratio becomes more direct as the steering is turned. In this way, the new TT can be steered agilely and precisely with little movement of the steering wheel in downtown traffic and on winding country roads. The electromechanically driven and thus highly efficient progressive steering adapts its assistance to speed and forms the basis for the optional assistance systems – Audi active lane assist and park assist.

With its elaborate chassis design and firm setup, the new Audi TT handles superbly in all situations. The body is lowered by 10 mm (0.39 inch) on the TTS, with the S line sport package and with the adaptive damper control system, Audi magnetic ride.

The dynamic driving system known as Audi drive select is an option for the new Audi TT, but standard on the TTS. It controls the engine characteristics and the steering assistance. The driver can choose between comfort, auto, dynamic, efficiency and individual modes. In addition, Audi drive select influences several optional modules – the S tronic, quattro drive, the Audi magnetic ride system, which at the press of a button makes the compact sports car hug the road even more closely, and the engine sound. In efficiency mode, Audi drive select influences the air conditioning and the start-stop system accordingly.

There are 11 different wheel versions available. The TT 2.0 TFSI and the 2.0 TDI come as standard with 17” forged wheels in five-spoke design, each of which weighs only 8.7 kg (19.18 lb), and with size 225/50 tires. On request, Audi can supply other wheel designs with diameters of 17”, 18” or 19”, and tires up to 245/35 R19. quattro GmbH also offers wheels with a diameter of up to 20”.

The front discs are ventilated and, depending on engine version, have a diameter of up to 338 mm (13.31 in). The new electromechanical parking brake that the driver actuates by pressing a button is integrated into the rear braking system. The TTS uses newly developed aluminum fixed-caliper brakes to slow the front wheels; these are five kilograms (11.02 lb) lighter than on the predecessor model – another example of Audi’s expertise in lightweight construction.

The electronic stabilization control (ESC), which can be switched off either partly or completely, perfectly complements the car’s sporty handling. When driving through bends, torque vectoring takes effect. If required, the drive torque is distributed from the inside front wheel to the outside front wheel (front-wheel drive) or, on quattro models, to the rear wheels, too. Thanks to the difference in propulsive forces, the car turns very easily into the curve, which is helpful for the driver. In this way, bends can be navigated with great precision and neutrally. This significantly boosts the TT’s dynamism and stability. Sport mode supports particularly sporty driving, facilitating steering and control when drifting.

The way that all components interact and harmonize enhances agile handling and consequently the driving pleasure that an Audi TT offers – just as you would expect of a sports car.

Equipment

All versions of the new Audi TT Coupé come with a generous range of standard equipment. Alongside those features already mentioned above, the MMI radio and the electromechanical parking brake deserve a special mention. The options include – alongside the S sport seat with numerous leather and trim variants – the convenience key, hold assist, high-beam assist, the LED interior lighting package, front seat heating, and the storage and luggage compartment package.

As regards infotainment, customers can choose from various options. The connectivity package boasts a touchpad, MMI touch. At the top of the modular range is the MMI Navigation plus with its large flash memory, two card readers, DVD drive, Bluetooth interface and voice control system. The T30 chip from market leader Nvidia’s Tegra 3 series, which is used in the new generation of the modular infotainment platform, controls all navigation and multimedia functions in the car and, together with the processor, presents all content in the Audi virtual cockpit.

The Audi connect system complements the MMI Navigation plus perfectly – it connects the new TT to the internet using the fast LTE transmission standard. The integrated Wi-Fi hotspot means passengers can surf the internet and e-mail as they please, while the driver can rely on the customized Audi connect services.

The infotainment package is rounded out by attractive components. The Audi Phone Box smoothly links a cell phone to the car. Its centerpiece is a universal planar antenna which is integrated into the storage tray in the center armrest. Thanks to close-range coupling, the phone communicates with the flat planar antenna, which uses an amplifier to transmit the signals to the car antenna.

The Bang & Olufsen Sound System features a 14-channel amplifier and 12 loudspeakers; the woofers in the doors gleam in the dark thanks to an adjustable, discrete light conductor.

Powerful assistance systems make driving the new TT an even more pleasurable experience. As an option the car can be equipped with Audi side assist, which uses rear-mounted radar sensors to help drivers change lane more safely; camera-based traffic sign recognition; Audi active lane assist, which helps the driver if required by steadily correcting steering or warning him or her if there is a danger of unintentionally drifting out of lane and the park assist system with display of surroundings, which independently guides the car into suitable spaces.
