Built for Fun at the Wheel

Audi is taking the wraps off a new sports car - the Audi TTS, the top of the TT model line. It will be coming to dealer showrooms in the early summer. Under its hood lies a two-liter TFSI high-performance engine delivering a mighty 272 bhp. This intense power propels the TTS Coupe to 60 mph from a standstill in just 5 seconds and on to a governor-limited top speed of 155. The Audi TTS is available as both a 2 + 2-seater coupe and as a roadster.

Designed to appeal to a young and dynamic clientele, the TTS represents the Audi brand's Vorsprung durch Technik ("advancement through technology") in its very latest form. The TFSI engine in the TTS takes the two Audi technologies of gasoline direct injection and turbocharging and blends them to form a perfect partnership. Aside from its output of 272 bhp, it is its peak torque of
258.15 lb-ft, which is constantly on tap between 2,500 and 5,000 rpm, that makes the compact and lightweight four-cylinder unit so impressive.

Compared to the engine it was derived from, the two-liter power unit has been reengineered and strengthened in a number of key areas to ready it for operation in the TTS. Thanks to its excellent efficiency, the sporty-sounding TFSI has an average fuel consumption of just 29.375 mpg in the Coupe when partnered by the six-speed manual transmission, while the figure for the roadster averages 28.659 mpg. These figures are improved by 0.372 and 0.716 mpg, respectively, if the optional S tronic dual-clutch transmission is fitted.

S tronic, which deploys two clutches, is capable of performing extremely quick gear shifts at high engine loads and rev speeds; consequently, the time taken to sprint from zero to 60 mph is cut by a further two-tenths of a second in both the Coupe and Roadster. Loss-free transfer of power to the road is the task of the standard quattro permanent all-wheel drive that enables the TTS to accelerate quicker and with greater stability than its rivals. At the heart of this system is a hydraulic multi-plate clutch that works faster than ever thanks to a new pressure reservoir.

The TTS rolls off the production line equipped with yet another high-tech module - the Audi magnetic ride adaptive damping system. This gives the driver the choice of two characteristic settings: "Standard" mode is designed for a well-balanced, comfortable ride, whereas in the "Sport" setting the TTS harnesses all of the potential of its sports suspension - which lowers the body by 0.39 in. - to deliver uncompromisingly dynamic handling. Its front suspension is mainly made of aluminum, while the efficient technology of the precision electromechanical steering also helps to improve fuel consumption considerably. The sports car is safely brought to a standstill by the high-performance braking system with its 17-inch discs.

Yet another factor in the supreme performance of the TTS is the hybrid construction of its body. Steel is used at the rear end, while the front and center sections of the body are built from lightweight aluminum. ASF (Audi Space Frame) technology optimizes axle load distribution and reduces the overall weight. The manual Coupe weighs just 3,075.45 lbs, which equates to a power-to-weight ratio of 11.24 lbs/bhp.

Powerful Looks

The Audi TTS instantly stands out as the dynamic flagship of the TT model line. The standard 18-inch aluminum wheels are a highlight of the exterior design, as are the headlights, comprising newly designed bi-xenon units with LED daytime running lights. Inside, passengers are welcomed by deep-set sports seats trimmed in a mixture of leather and Alcantara, with Silk Nappa leather seat upholstery in four different color combinations available as an option. The gray instrument panel as well as the multifunctional steering wheel add further styling touches.

The Interior

Awaiting the passengers inside are deep-set sports seats featuring seat heating and height adjustment. They come as standard with leather/Alcantara seat covers in either black or black and silver, plus silver-colored contrast stitching. The sports seats are optionally available in Silk Nappa leather upholstery. There is also the option of the Impulse leather package, comprising black trim with silver stitching in the Coupe or chennai brown trim with espresso-colored contrast stitching in the Roadster.

The cockpit in the TTS is molded around the driver like a sleek-fitting suit. Its clean-cut, sporty design and uncompromising quality of construction is another Audi trademark. Instruments with a gray background and white needles, metal pedals, aluminum trim panels, plus a multifunctional leather sports steering wheel with a rim that's flattened at the bottom add further styling touches.

Sporty Passion: The New TT Roadster

Sheer sportiness, a genuine driving experience plus high power reserves - cue the new TT Roadster from Audi. The open-top sports car retains the distinctive lines of its tremendously successful predecessor, but instills them with even greater emotion, performance and dynamism.

Audi offers a choice of two engines for its new TT Roadster. The 3.2-liter V6 power unit generates 250 bhp and is coupled to the quattro drive system as standard. The 2.0 TFSI engine, which blends turbocharging with petrol direct injection technology, delivers 200 bhp to the front wheels. Both model variants can be ordered with the innovative S tronic dual-clutch gearbox as an alternative to the standard six-speed manual shift.

The Exterior Design

With its rigorous geometry and clarity, the design of the first TT Roadster elevated it to the status of a cult classic. Audi has preserved the charismatic design idiom and carefully honed it for the new model.

Whereas the tail end and the roof section seem to flow into one another at the rear of the TT Coupe, the soft top of the TT Roadster forms a clear contrast that gives the overall design a more geometric look. The body's lines brim with power and forward thrust. This impression is underscored by the athletic curves of the vehicle's flanks just as much as by the rising dynamic line above the sill area and the taut, muscular shoulder line. The eye-catching fuel filler cap positioned above the rear right wheel sports a classic aluminum design.

The TT Roadster 3.2 quattro comes as standard with an electro-hydraulically powered soft top, which is available for the 2.0 TFSI as an option. This version of the soft top opens in just 12 seconds at the push of a button, and can even be operated on the move at speeds of up to 30 mph. The fully automatic hood incorporates an additional layer of soundproofing beneath the black headliner for even better acoustic and thermal insulation.

The face of the new Audi TT Roadster has an expressive feel. Wing-shaped plastic elements are embedded into the slanted, sharply tapered headlights to emphasize the three-dimensional depth of the lamp units. At the rear of the car, it is the large tailpipes and the wide diffuser which stand out. The tube-shaped reflectors seem to hover inside the tail light units. As on the Coupe, an electrically powered spoiler rises up out of the boot lid when the speed reaches 75 mph.

The Interior

The interior of the TT Roadster is noticeably larger too, offering extra headroom and elbow room.

Deep-set sports seats provide firm lateral support for both the driver and passenger. The standard-specification leather sports steering wheel features a flat-bottomed rim. The optional Impulse leather trim with its distinctive topstitching already attained cult status when it was offered for the outgoing model; it is one of four different leather trim packages. The 3.2 quattro is upholstered in a combined Alcantara/Leather trim as standard.

The three circular air outlets and the dome shrouding the instrument cluster dials inject the cockpit with characteristic TT flair. As is to be expected of an Audi, the ergonomic concept is perfect and the workmanship of the very finest standard. The increase in the body's dimensions has also benefited luggage space, which has expanded from 210 to 250 liters in both the front-wheel-drive and the quattro variant.

The Drive Train

Like the TT Coupe, the new Roadster is available with a choice of two transverse-mounted petrol engines. Both generate high pulling power and impressive peak output, resulting in out-and-out sporty performance. The four-cylinder engine directs its power to the front wheels, while the V6 powers all four wheels based on the quattro principle offering dynamism and sure roadholding in equal measure. Apart from a sporty six-speed manual shift, both engines are also available in conjunction with the innovative S tronic dual-clutch gearbox for lightning-fast gear changes without any interruption in the power flow.

The V6 unit with its capacity of 3,189 cc delivers 250 bhp and a peak torque of 236 lb-ft which is on tap between 2,500 and 3,000 rpm. The sonorous, ultra-compact long-stroke engine features two continuously adjustable camshafts. The TT Roadster 3.2 quattro sprints from 0 - 60 mph in 5.7 seconds with the S tronic gearbox and can, if necessary, go on to reach a governed top speed of 155 mph. It returns average fuel consumption figures of 9.5 l/100 km.

Power Born from Passion: The New Audi TT Coupe

A cult car, an icon - the Audi TT, launched in the autumn of 1998 - took the sports coupe segment by storm and sharpened the brand profile. Now the second generation of this successful model is making its debut. The new TT Coupe is even more dynamic than its predecessor - in terms of its design, its drivetrain, and its running gear.

The New Audi TT's Exterior

The very architecture of the new Audi TT Coupe embodies the style, stability and power of a pure driving machine. The bullish stance of the base body and the low, narrow styling of the greenhouse together form a sculpture of simple, unfussy lines. The Audi design team has lovingly adopted and enhanced the visual code - the motif of circles and domes - of the predecessor model. The new Audi TT appears more stretched, and even at a standstill seems to be striving to move forward; taut panels emphasize the impression of dynamic movement. The new TT is 5.3 inches longer than its predecessor at 162.9 inches, and 3 inches wider at 71.8 inches.

The body is constructed in the ASF Space Frame design developed by Audi and consists of aluminum and steel. This is the first time that it has combined different materials alongside each other. 69 percent of the superstructure is made of aluminum. The steel components making up the remaining 31 percent are to be found at the rear end, so as to ensure balanced distribution of the axle loads. To improve downforce, a spoiler is extended from the tailgate when the vehicle reaches a speed of 75 mph.

The new Audi TT, like its predecessor, is initially available as a 2 + 2-seater coupe; the separate roadster model is scheduled for later launch. The basic luggage capacity of the easily accessible boot, under its large-format lid, is 290 liters. This capacity can be increased to 700 liters by folding down the rear seat backs. The sports seats provide outstanding side restraint. There is a choice of three different leathers for the covers.

The Cockpit

The cockpit is oriented strictly to the driver and is perfectly ergonomic in design. It embodies the classic circles motif of the TT in a number of ways, such as in the three centre air vents.

Engines: 2.0l Turbocharged Four-cylinder or 3.2-liter V6

Two powerful petrol engines are available to power the car. The 2.0l turbocharged four-cylinder TFSI unit featuring FSI direct injection develops 200 bhp. With a six-speed manual gearbox, it accelerates the TT to 60 mph in just 6.2 seconds, reaching a top speed of 150 mph. The sonorous-sounding, naturally aspirated 3.2-liter V6 engine develops 250 bhp, accelerating from zero to 60 mph in 5.5 seconds and reaching a top speed of 155 mph (electronically governed).

Both engines are equipped with a six-speed manual gearbox. On request they can be combined with the dynamic S-tronic dual-clutch gearbox. Whereas the four-cylinder engine comes with front-wheel drive, the V6 distributes its power across both axles by way of the quattro permanent four-wheel drive system - an exclusive technology feature in the sports coupe segment.

The Suspension

The Audi dynamic suspension was newly developed and tuned for the Audi TT Coupe. One of its hallmarks is its self-steering behavior right up to the handling limits, which ranges from neutral to light understeer. This sporty orientation produces driving fun, agility and supreme handling characteristics.

The track enlargement, with larger wheels ranging from 16 to 19 inches in size, and extensive changes in the area of elastokinematics were key areas of the developers' work. The new multi-link rear suspension ensures optimum driving dynamics at a sports car level.

The high-tech Audi magnetic ride damper system is available as an option. In this system, tiny magnetic particles circulate in the oil inside the shock absorbers. When a voltage is applied to them, they alter the damping characteristics within milliseconds. This adaptive system simultaneously ensures high levels of ride comfort and thoroughly sporty dynamism, according to the specific driving scenario and the preferences of the driver.

Comfortable, Too

The standard features of the new Audi TT include an automatic air conditioning system and a flat-bottomed sports steering wheel. The latter is not only entirely suitable for the sports car but also makes it easier to get in and out. The air vents, steering wheel spokes and many of the controls are finished in an aluminum look.

With regard to options, customers can choose from a variety of high-tech solutions, including the adaptive light dynamic cornering light system and the Audi parking system which aids parking.

The new Audi TT marks the premiere of a new generation of audio systems. It is characterized by state-of-the-art reception and playback technology and intuitive user control. Six so-called softkeys control a variety of functions depending on which menu is selected. The chorus radio system with single CD drive comes as standard. A Bluetooth interface is available for mobile phones. The telephone function can be operated via the MMI, the multifunction steering wheel and by speech control. The operator control for the optional navigation system takes its cues from the exemplary MMI system familiar from the Audi A6, A8 and Q7 model series.

Among the high-performance coupes, the Audi S5 with its combination of V8 FSI technology and quattro permanent all-wheel drive truly stands alone. The eight-cylinder engine with superb power potential is well matched with the specially tuned sports suspension and high-performance brakes.

Design und interior

Unobtrusive but unmistakable design elements inside and out give this athlete among Audi models its unique image. The Audi S5 looks at you with poised power: Its radiator grill is platinum gray and has vertical chrome inlays. Front as well as rear bumpers have a more pronounced outline and an aluminum blade emphasizes the air intake grills.

The aluminum-look outside mirror housings leave no doubt of the S5's personality, and neither do the color-matched door sill trims and the exhaust system with four oval tailpipes. The more strongly pronounced trunk lid spoiler edge provides increased aerodynamic downforce.

But the design of the S5 interior also emphasizes its dynamic character: The S sports seats and sports steering wheel, instruments with gray dials and special aluminum door sill plates create an atmosphere of refined power. The interior leaves a great deal of space for the realization of personal ideas: Audi makes available a wide scope of special materials and colors.

Drivetrain

260 kW (354 hp) is the output of the 4.2-liter eight-cylinder engine in the Audi S5, with a maximum torque of 440 Nm (324.53 lb-ft) already available at 3,500 rpm. In no more than 5.1 seconds, the powerful coupe sprints to 100 km/h (62.14 mph), showing exceptional liveliness, spontaneous response, a continuous power curve and an exhilarating sound. The V8 derives its enormous power potential from the innovative FSI direct injection technology.

It takes only sparing motions to operate the six-speed transmission. The clutch was relocated to behind the differential - a swap which allowed to move the front axle further up and thus achieved a more ideal weight balance. As an option, the sporty six-speed tiptronic is available. The quattro permanent all-wheel drive of course provides perfect traction with variable torque distribution and a basic split of 40 percent to the front and 60 percent to the rear axle.

Chassis

The S sports suspension supports the Audi S5's performance through its dynamic tuning. The high-performance brakes, recognizable by their black painted brake calipers, ensure reliable deceleration. The ESP stabilization system can be suspended in two steps if the driver wishes to investigate the potential of her Audi S5 on a suitable course. The 18-inch wheels are matched to tires of the size 245/40 R 18.

As an option, Audi fits the S5 with the dynamic high-tech drive system, Audi drive select. It allows the driver to shift the characteristics of the throttle, of the tiptronic shift points, and of the power steering support in three modes; and if the navigation system plus is installed as well, the driver can even design their own personal drive program.

As additional components, there are the adaptive shock absorbers and the new Audi dynamic steering system. With its override differential drive it varies the steering ratio depending on driving speed; and in fast turns, the system keeps the S5 safely and dynamically on the road by small, automatically performed corrections.

Equipment

Among the S5 standard equipment there are the xenon plus headlights with their impressive strip of LED daytime running lights and electrically adjustable S sports seats fitted with attractive fabric/leather coverings. As a member of the A5 family, this high-performance coupe can be equipped with state-of-the-art communication and entertainment devices, from the Bang & Olufsen sound system and the intelligent iPod interface to the Bluetooth car telephone.

The S5 can also be equipped with high-tech systems such as adaptive cruise control, Audi side assist, Audi lane assist and Audi parking system advanced. They help maintain distance to the car ahead, assist in changing and maintaining lanes, and make reverse-parking easier by using a camera. For some of the further, highly attractive upgrades, there are 19- and 20-inch wheels as well as the keyless entry system advanced key.

The Audi S5 at a glance:

Engine: displacement 4,163 cc, power output 260 kW (354 hp) at 7,000 rpm, maximum torque 440 Nm (324.53 lb-ft) at 3,500 rpm.

Avant, with the Dynamism of a High-Performance Sports Car

Outstanding top performance and maximum dynamism combined with excellent suitability for everyday use are the impressive features of the new Audi RS 6 Avant, which has been unveiled to the public for the first time at the IAA 2007 in Frankfurt. A newly developed V10 engine with FSI direct injection and twin turbochargers, permanent quattro four-wheel drive and sports suspension with Dynamic Ride Control DRC set the standard for high-performance vehicles in the luxury class. 580 bhp and a maximum torque of 480 lb-ft add up to an unforgettable performance experience. At the same time, the new Audi RS 6 Avant offers a high standard of travel comfort - on long journeys, too.

The new Audi RS 6 will only be available as an Avant to start with, with the unrivalled combination of 580 bhp and a maximum 1,660 liters of luggage space.

The Audi RS 6 is a New Leader in the Performance Category

The Audi RS 6 redefines the term "high performance" in the business class. With its 580 bhp, it is the most powerful model in the current Audi range and - with the exception of pure racing cars like the Le Mans-winning Audi R10 TDI - the most potent Audi of all time. But not only that: it is also clearly superior to all competitors in the top performance category.

The ten-cylinder V-configuration engine in the RS 6 is based on the V10 powerplants of the Audi S6 and Audi S8, but has been redeveloped in practically every respect to attain the significantly higher level of performance. The twin turbochargers ensure an impressively constant stream of power over the entire engine speed range: the mighty peak torque of 480 lb-ft is available across the entire range from 1,500 to 6,250 rpm; maximum output is available between 6,250 and 6,700 rpm.

This powerplant enables the Audi RS 6 Avant to achieve the road performance of a high-performance sports car. It requires just 4.4 seconds for the sprint from a standing start to 60 mph, and reaches the 124 mph mark in a mere 14.9 seconds. Only when the needle touches 155 mph is the propulsive power electronically governed.

The six-speed tiptronic is the perfect complement to the self-confident, powerful character of the RS 6. Its hydraulics and control system have been optimized to achieve exceptionally short shift times; the ratios have been adapted accordingly.

In its basic setting, the center differential distributes 40 percent of the power to the front and 60 percent to the rear wheels - this slightly rear-biased setup produces particularly dynamic handling characteristics.

An Individual Driving Feel

With Dynamic Ride Control the shock absorbers are connected diagonally with each other via two oil lines and two control valves. Body movement - e.g. rolling when cornering at high speed on an uneven road surface - produces flows of oil, which generate additional damping force. As a result, the RS 6 boasts even more directional control through bends and reacts with substantially more precision to the steering inputs of the driver.

Dynamic Ride Control on the new RS 6 can be supplemented if desired with optional three-stage damping. This allows the driver to select the handling characteristics according to his/her personal preferences or chosen route. In the comfort setting, the sports suspension plus provides remarkable ride comfort, in the dynamic program it adjusts superbly to an enthusiastic driving style and in the sport mode it delivers maximum driving precision.

Self-Assured Appearance

Its independent design lends the Audi RS 6 a striking and self-assured look - without any hint of aggression. In fact, the clear front-end design with the remodelled bumper and accentuated apertures evidently follows function: the high-performance powerplant requires a considerable amount of air to breathe as well as for cooling. The fact that it belongs to the RS family is emphasized by the matt aluminum-look single-frame grille featuring a highly polished black guard in a diamond design.

Elegant and Exclusive Interior

The interior of the new RS 6 offers an impressive synthesis of sporty elegance and exclusiveness. The extremely high standard of craftsmanship typical for Audi is complemented by an equally sporty and elegant combination of top-class materials. Carbon fiber, aluminum, leather and Alcantara create an ambience that is unique even in the world of high-performance cars.

The main control element is and remains the steering wheel: on the RS 6 the customer can choose between the multifunction sports steering wheel with a 3-spoke design and the particularly distinctive flat-bottomed RS sports steering wheel, likewise with multifunction controls and shift paddles for the transmission. The cockpit in the typical RS design additionally features a boost pressure gauge. Displays for boost pressure, oil temperature and lap timer can be called up via the driver information system.

Outstanding Torque for the Top Class

Audi is presenting a revolution in the top class at the Detroit Auto Show 2008 - the first 12-cylinder diesel engine in a high-performance roadgoing sports car. The V12 TDI with a displacement of six liters powers a concept car based on the Audi R8. This unit generates a huge 500 bhp and 737.56 lb-ft of torque. Audi is writing a new chapter in diesel technology with this power unit. Equipped with the expertise that Audi has built up through its motor sport activities, the R8 V12 TDI in matt "Grace Silver" embodies superb road handling, pioneering technology and fascinating design.

The V12 TDI is closely related to the engine in the Audi R10, the two-time Le Mans winner - so it catapults the Audi R8 into supercar terrain concerning performance too. It sprints from zero to 60 mph in just 4.2 seconds and its top speed is well over 186.41 mph. The peak torque, reached at only 1,750 rpm, paves the way for effortless acceleration that is unrivaled even at this level.

The Genes of the Winner

Thanks to their high performance and pulling power, all Audi TDI engines are ultra-dynamic sources of power. The brand has often enough demonstrated its sporty character in its production cars, especially the six- and eight-cylinder 3.0 TDI and 4.2 TDI. Audi has also been writing a new chapter in its success story on the racetrack since 2006. The diesel engine in the R10 sports prototype won its very first endurance race at Sebring, Florida, when it was pitted against an entire field of gasoline-engined challengers. But its most crucial victories were surely in 2006 and 2007 in the 24 Hours of Le Mans, when it simply outclassed the international elite.

The V12 TDI race engine in the R10 produces over 650 bhp from a displacement of 5.5 liters, giving it the potential for a top speed as high as 205.05 mph depending on the gear ratios. Its power and sturdiness immediately impressed both fans and experts, who were impressed by its restrained noise level. Unusual for a race engine, this powerful Audi diesel makes barely more than a whisper.

The Drivetrain

Audi's engineers were in an ideal position to use their experience building the racing engine to develop the road version. Like the other power units in this range, the distance between cylinder bore axes on the V12 TDI is 90 mm (3.54 in.). Yet its included angle is 60 degrees, not 90 degrees. This means no free inertial forces or mass moments of inertia can occur with the V12. The results are refined in every respect.

The two turbochargers, which generate up to 2.6 bar of boost pressure, play a crucial role in producing the huge torque of 737.56 lb-ft that the V12 TDI maintains from 1,750 rpm to 3,000 rpm. In developing 500 bhp, the diesel achieves a specific output of 84.3 bhp per liter displacement.

Two large intercoolers reduce the temperature of the compressed air. The V12 has a twin-pipe exhaust system with two particulate filters. The intake system is similar in structure with one air cleaner per cylinder bank, with an airflow meter behind it. Two control units, sharing the workload in a master/slave principle, manage events in the engine.

The Design

The R8 V12 TDI concept with matt "Grace Silver" bodywork looks even wider and more resolute than the core model. It shows its potential through its muscular proportions, accentuated wheel arches and even larger air apertures. The rhombuspattern cover on the air inlets and outlets is the hallmark of Audi's sporty top models and a familiar feature of the current RS generation.

Typical of the side view of the R8 is the sideblade. Much wider in the bottom third, it visually accentuates the engine's position as well as acting as an enlarged air deflector.

The continuous aluminum spoiler lip that connects the front and rear diffusers with side air baffles below the enlarged sills also pays tribute to this version's highly developed dynamic talents.

Ergonomic and Elegant Interior

The interior's design is as sporty and exclusive as the exterior: the characteristic element here is the monoposto - an expansive arc running around the steering wheel and instruments, connecting the driver to the car. The interior consequently picks up on the dynamism of the R8 V12 TDI concept and gives it tactile expression in a form that is accessible the moment you climb in.

The start/stop button for the engine and the Drive Select switch with the Dynamic/Sport/Race settings are arranged on the steering wheel. The latter controls the engine and transmission electronics as well as the magnetic ride dampeners in each of three different modes.

In Race mode, the instrument lighting changes from white to red. The navigation system shows a combined display with lap timer and navigation information for the racetrack being driven. Or supplementary information such as centrifugal force and boost pressure can be called up.
