2009 Audi TTS

Audi is taking the wraps off a new sports car at the North American International Auto Show in Detroit on Sunday, January 13, 2008 with the Audi TTS, the top of the TT model line. It will be coming to dealer showrooms in the early summer (late November 2008 in the U.S.). Under its hood lies a two-liter TFSI high-performance engine delivering a mighty 200 kW or 272 hp (265 hp in the U.S.). This intense power propels the TTS Coupe to 100 km/h (62.14 mph) from a standstill in just 5.2 seconds and on to a governor-limited top speed of 250 km/h (155.34 mph). 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 200 kW or 272 hp (265 hp in the U.S.), it is its peak torque of 350 Nm (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 8.0 liters of fuel per 100 kilometers (29.375 mpg – European specification) in the Coupe when partnered by the six-speed manual transmission (not available in the U.S.), while the figure for the roadster averages 8.2 l/100 km (28.659 mpg – European specification). These figures are improved by 0.1 and 0.2 l/100 km (by 0.372 and 0.716 mpg – European specification), respectively, if the optional S tronic dual-clutch transmission is fitted (exclusively offered in the U.S.).

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 100 km/h (62.14 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 10 millimeters (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 1,395 kilograms (3,075.45 lbs – European specification), which equates to a power-to-weight ratio of 5.1 kg/hp (11.24 lbs/hp – European specification).

Powerful looks: 18-inch wheels plus new headlights

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 TTS Roadster comes with an electrohydraulic drive for the soft top, a power wind deflector, plus, for added practicality, a load-through facility. The rear seats in the Coupe have a split-folding design, allowing luggage capacity to be increased from 290 to 700 liters (10.24 to 24.72 cubic ft.). The hard-top TTS is priced at 44,900 euros and the convertible version at 47,750 euros.

The unveiling of the TTS also marks something of an anniversary for Audi: It was 10 years ago that the TT Coupe first took to the road, swiftly acquiring the status of design icon. And the TT has stayed firmly in the fast lane ever since.

The Drivetrain

The TFSI engine fitted in the TTS summons its power from a displacement of 1984 cc, and blends two separate Audi technologies – gasoline direct injection and turbocharging – to form a partnership that is perfect for a sports car. It is with good reason that an international jury of motoring journalists has crowned the two-liter four-cylinder power unit 'Engine of the Year' three times in succession since 2005.

It is not only the 200 kW or 272 hp (265 hp in the U.S.) of output that makes the TFSI so scintillating, there's its hefty pulling power too – the maximum torque of 350 Nm (258.15 lb-ft) is constantly on tap from 2,500 up to 5,000 rpm. The Coupe with manual transmission (not available in the U.S.) takes just 5.4 seconds to race from zero to 100 km/h (62.14 mph), while a mere 4.4 seconds are required to speed up from 80 to 120 km/h (49.71 to 74.56 mph) in fourth gear. The Roadster is almost as impressive, recording times of 5.6 and 4.6 seconds respectively for the same two exercises. The electronic limiter calls a halt to this outstanding propulsion at a speed of 250 km/h

(155.34 mph) in both models.

Compared to the engine it was derived from, the two-liter power unit has undergone extensive reengineering and strengthening to ready it for operation in the TTS – overhauled areas include the engine block, the cylinder head, the pistons, the connecting rods and the turbocharger, which can build up as much as 1.2 bar of relative air pressure. The intake and exhaust systems have undergone elaborate honing to allow the refined four-cylinder engine to both breathe freely and generate a powerful, resonant soundtrack. An optimized and highly efficient intercooler lowers the temperature of the compressed air, producing a crucial increase in the quantity of air supplied for combustion.

Thanks to its outstanding efficiency, the TFSI has impressive fuel consumption of 7.9 liters per 100 km (29.747 mpg – European specification) in the Coupe when partnered by the S tronic transmission, and just 8.0 l/100 km (29.375 mpg – European specification) in the Roadster. The two-liter engine is extremely light, weighing in at 153 kilograms (337.31 lbs). This has considerable benefits for the overall weight of the TTS as well as for the axle load distribution and, consequently, for the vehicle's handling.

High-tech gearshifting: S tronic

Transmission of the engine's power is handled as standard in the TTS by a manual six-speed gearshift (not available in the U.S.) with a light-weight magnesium housing. As an alternative, customers can opt for S tronic (exclusively offered in the U.S.), which operates using six gears and two clutches positioned one behind the other. At high engine loads and rev speeds, it is capable of shifting in just two-tenths of a second. As a result of this high-speed shift work and its dynamic start-off capabilities, the dual-clutch transmission from Audi shaves a whole two-tenths off the time taken for the sprint from zero to 100 km/h (62.14 mph) in both the Coupe and the Roadster.

S tronic, which likewise boasts excellent efficiency, also allows the driver to shift gears manually using the one-touch lever or by means of paddles on the steering wheel, just like in a racing car. There is also a choice of two automatic operating modes: N for 'Normal' and S for 'Sport.' The clutches also have an adaptive design, enabling the start-off characteristics to be varied – whereas caution is exercised on slippery surfaces, full power can be unleashed at the driver's command when there is firm grip.

The standard-specification quattro permanent all-wheel drive ensures loss-free transfer of the engine's power to the road. With drive power being delivered to all four wheels, the TTS is able to accelerate quicker and more safely than its rivals, delivering dynamism coupled with supreme stability under all conditions.

At the heart of the quattro system is an electronically controlled and hydraulically operated multi-plate clutch, which now works even faster than ever thanks to a new pressure reservoir. If required, all of the drive force can be redirected from the front to the rear wheels within a matter of milliseconds. To make allowance for the high torques produced by the TFSI engine in the TTS, the drive train has been reinforced as required.

The Chassis

Audi has opted for a McPherson front suspension with lower triangular wishbones for the TTS. The suspension is largely made of aluminum, thereby reducing the unsprung masses. With a view to increasing rigidity, the subframe is bolted to the body at six points. The sensitive, high-precision power steering is driven electromechanically, a technology that improves fuel consumption by 0.2 liters per 100 km (0.716 mpg). The characteristics of the steering's power assistance have been adapted to reflect the dynamic nature of the TTS.

The four-link rear suspension offers considerable benefits for vehicle handling, as it is capable of dealing with the longitudinal and lateral forces separately from one another. All of the links are made from high-strength grades of steel, while modified bearings emphasize the taut feel of the TTS. The coil springs and shock absorbers are fitted separately from one another, meaning that they take up little space.

The TTS comes standard with 18-inch cast aluminum wheels that sport the five-arm parallel-spoke S design and are shod with 245/40-size tires. Further wheel variants are optionally available, including a new 19-inch cast aluminum wheel designed by quattro GmbH (USA pricing and options are still TBD). The exceptionally dynamic top-of-the-line TT model comes equipped with a high-performance braking system. Large disks are fitted front and rear, with the front disks being internally ventilated too. Inside the black-painted calipers, which bear the TTS emblem at the front, are the sport brake pads. Audi has devised a second, sporty level for the ESP stabilization program which enables controlled drifting.

Audi magnetic ride – crisp and versatile

The TTS rolls off the production line equipped with yet another high-tech solution — the Audi magnetic ride adaptive suspension system. Circulating inside the damper pistons is a special fluid containing minute magnetic particles. When an electrical voltage is applied, the oil's flow properties change the characteristics of the suspension.

Audi magnetic ride works adaptively, meaning that it adjusts automatically to suit the prevailing conditions. The driver can select one of two suspension settings. In 'Normal' mode, when oil viscosity is high, the TTS offers a well-balanced, comfortable ride. In the 'Sport' setting, meaning low viscosity, the TTS harnesses all of the potential of its sports suspension – which lowers the body by 10 millimeters (0.39 in.) – to deliver uncompromisingly dynamic handling.

The Audi generates non-stop fun at the wheel as it speeds around corners like a go-cart with absolute crispness and precision, seemingly glued to the road. Any body roll is suppressed from the moment the vehicle starts to turn. The steering becomes more responsive and direct, and selective bracing of the wheels makes the self-steering more neutral.

The Body

The superior performance of the TTS can be partly attributed to the technology of its bodywork, whose hybrid construction combines two different types of materials. Steel is used at the rear end, while the front and center sections of the body are built from lightweight aluminum.

Audi first developed this principle, known as the Audi Space Frame (ASF), in the early 1990s, triggering a revolution in body manufacturing. Extruded sections, pressure die-castings and load-bearing aluminum panels together form a light, rigid and extremely safe structure. On the Coupe, the side sections and the roof are laser welded together, producing a precision seamless joint — another clear indication of how Audi strives for perfection when building its cars.

The construction of the TTS has the added major benefit of optimizing distribution of the axle loads and reducing the vehicle's total weight. The Coupe's body weighs a mere 206 kilograms (454.15 lbs), of which 140 kg (308.65 lbs) is aluminum and 66 kg (145.51 lbs) steel. In the case of the TTS Roadster, whose body incorporates special reinforcements, the figure is 251 kilograms (553.36 lbs). All in all, the manual version of the Coupe weighs in at just 1,395 kilograms (3,075.45 lbs), equating to a power-to-weight ratio of 5.1 kilograms (11.24 lbs – European specification)) per hp. The Roadster's weight of 1,455 kilograms (3,207.73 lbs), meanwhile, corresponds to a ratio of 5.4 kg/hp (11.90 lbs/hp – European specification).

The Audi TTS instantly stands out as the dynamic flagship of the TT model line. One of the design highlights is undoubtedly the headlights – newly designed bi-xenon units featuring a horizontal strip of white LEDs that serve as daytime running lights. The single-frame grill in a platinum gray finish is embellished with slender chrome strips, while large air intakes in the restyled front apron add to the striking look.

When viewed in profile, it is not only the large 18-inch wheels that stand out; the widened, deeper door sills are equally eye-catching. A muscular rear bumper, a gray-colored diffusor trim, plus two sets of twin tailpipes protruding from the left and the right inject the vehicle's tail with a sporty character all of its own. The spoiler on the TTS extends automatically when the speed reaches 120 km/h

(74.56 mph) and retracts again when it drops back to 80 km/h (49.71 mph).

Both the Coupe and the Roadster measure 4,198 millimeters (13.77 ft) long and 1,842 mm (6.04 ft) wide; the hard-top TTS is 1,345 mm (4.41 ft) in height, its open-top counterpart 1,350 mm (4.43 ft). The Roadster features an electrohydraulically operated soft top which opens and closes in twelve seconds, even on the move at speeds below 50 km/h (31.07 mph). The soft top incorporates a large glass rear window and folds in a 'Z' shape. Neither a tonneau cover nor a cover flap is needed. Extra matting between the headlining and the outer skin improves insulation, and an electrically extending/retracting wind deflector shields the occupants' necks from drafts when the hood is down.

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.

The driver information system with its new, high-resolution white display concentrates all important information where it can be clearly seen by the driver, and includes a timer function that is able to record lap times on race tracks. Mobile entertainment out on the road comes in the form of the chorus audio system with CD player.

As well as being great fun to drive, the new sports car from Audi boasts a host of credentials that make it eminently suitable for day-to-day use. The Roadster is available with an optional load-through facility complete with removable ski bag for added practicality. The trunk has a capacity of 250 liters (8.83 cubic ft). The rear seats in the Coupe have a split-folding design, allowing luggage capacity to be increased from 290 to 700 liters (10.24 to 24.72 cubic ft.).

The Features (Pricing and Equipment TBD prior to U.S. Launch)

Sales of the TTS will begin in the early summer (late November 2008 in the U.S.). The Coupe is priced at 44,900 euros and the Roadster at 47,750 euros (TBD in the U.S.). The TT line's dynamic top model comes generously equipped. Its list of features includes quattro permanent all-wheel drive, the Audi magnetic ride adaptive suspension system, 18-inch aluminum wheels, xenon plus headlights with LED daytime running lights, plus – on the Roadster – the fully automatic soft top including power wind deflector.

The interior is dominated by the multifunctional leather sports steering wheel. The extended aluminum styling and heated sports seats with their leather/Alcantara upholstery are further highlights. An automatic air conditioning system and Isofix child seat mountings on the front passenger seat are designed to enhance both comfort and safety.

The list of optional extras includes two navigation systems, a Bose sound system, an iPod port, an LED interior lighting package, electrically adjustable seats, as well as the Audi adaptive light dynamic cornering light system. The S tronic dual-clutch transmission is an Audi technology that remains unmatched by anything the competition has to offer.

Ten Years of Audi TT – A Decade of Success

The unveiling of the TTS marks something of an anniversary for Audi: It was 10 years ago that the TT Coupe first took to the road, swiftly acquiring the status of a design icon. Ever since then the TT has been going from one strength to the next, in both hard-top and open-top form.

The prototype that was premiered by Audi at the Frankfurt Motor Show in September 1995, painted in silver gray, instantly captured the imagination of the show visitors. The strict consistency of its puristic form drew on the Bauhaus style of the 1920s. The solidly built body, the sleek glass house, the strict geometry of the shoulder line and circular arcs, the large wheels and the aluminum tank cap – all of these elements added up to deliver a new statement from Audi, the innovative technology brand. A few weeks later the Roadster appeared at the Tokyo Motor Show where it was also a tremendous hit.

The Coupe started to roll off the production line in 1998, followed one year later by the Roadster. The shortened floor assembly of the Audi A3 proved to form an ideal base for the car – its wheel suspension endowed the TT with dynamic handling characteristics. The puristic design was also retained for the interior. Here, the classic emblem of the TT concept, the circle, had a leading role to play, featuring in the styling of the air outlets and many of the controls.

The first TT was powered by the turbocharged 1.8-liter four-cylinder drive unit, which came in two different versions. The basic unit delivered an output of 132 kW (180 hp) and the top version 165 kW (225 hp). The more powerful engine was available exclusively with a six-speed manual transmission and quattro drive. Customers buying the basic version had the choice of either the six-speed technology again or front-wheel drive combined with a five-speed transmission.

Audi started to expand the range of drivetrain options in 2001. First came a new version of the 1.8-liter unit generating 110 kW (150 hp), followed in 2003 by a 3.2 liter V6 developing 184 kW (250 hp). This new engine could be matched with the S tronic dual-clutch transmission as an option. The six-speed tiptronic transmission became available for the 132 kW (180 hp) four-cylinder model with front-wheel drive. In 2005, this engine's output was increased to 140 kW (190 hp) and the power output of the entry-level unit jumped to 120 kW (163 hp). Production of the coupe and roadster versions of the first TT model series ended in 2006 and 2007 respectively.

As the 20th Century neared its end, it appeared as if car design, too, was taking its final gasps. The automobile was being replaced by a device more akin to a rolling computer than an instrument of freedom. Romance was being drained from the automotive scene as cars like the Toyota Prius became more fashionable than performance cars and isolated SUVs towered above the fine-handling sedans and wagons that seemed to have fallen out of public favor.

The problem was obvious: technology, safety features, and environmental concerns were reshaping the priorities of the automobile, and no manufacturer could figure out how to work those ingredients into the recipe for a truly exciting car. The problem was obvious, but the solution was not.

One manufacturer would come through, though, with a car that satisfied the evolving automotive zeitgeist even as it appealed to the more traditionally stimulating automotive values of beauty and driving excitement. That manufacturer was Audi, and the car was the TT.

By the late 1990s, Audi had established a remarkably strong brand identity considering the difficulties faced by the company just a decade prior. When Audi was charting out new territory in the 1980s through its pioneering developments in all-wheel-drive technology and aerodynamics, the company made sure to not lock itself into a strict brand image as had the other mainstream German automakers. Volkswagen produced cars for the masses, BMW produced cars for the driving enthusiast, and Mercedes-Benz produced cars for those who preferred (and could afford) supreme comfort and solidity.

Audi, conversely, did not adopt strictly static elements, such as sportiness or luxuriousness, as it defined its products in the 1980s. Audi instead developed a dynamic formula for creating cars that could be sporty, luxurious, and even fashionable through their remarkable ability to embrace technology and apply the ever-changing ideas of auto design to an innovative and capable product.

So while BMW tried to make their cars quick and Mercedes-Benz tried to make their cars comfortable, Audi tried only to produce a better car by riding the crests of technological waves. This strategy, after years of application, created the clear brand image that Audi has today. The 1980s saw Audi develop one of the most radically aerodynamic sedans of its time, as well as the successful use of all-wheel-drive as a means of improving handling in all weather conditions.

It followed naturally, then, that Audi should be one of the first automakers to successfully create a new type of car for the new millennium—a car that applied modern ideas, including the technology responsible for creating some of the most uninspiring and over-processed automobiles that the world had ever known, to an exciting and innovative package.

When the Audi TT was introduced in 1998 for the 1999 model year, it was an absolute sensation. Everything about it spoke to a new generation of automotive design. Though the TT would eventually be offered with a six-cylinder power plant, it was initially offered only with a turbocharged four-cylinder—a brave step for a car aimed at six-cylindered rivals from Porsche and BMW. The TT was available with front-wheel-drive, or with 'quattro' all-wheel-drive, both of which offered better foul-weather traction than rear-wheel-driven competitors.

The real audacity of the TT did not come from its small-displacement engine or its odd choice of drive wheels, though, but from its radical appearance dictated by J Mays and Freeman Thomas. With its Bauhaus-inspired design language, replete with perfectly sculpted fender flares and a bold roofline, the TT's design was bristling with the ideas of a new automotive age. The look was remarkably solid, an effect accentuated on silver TTs, which appeared to have been milled from a single block of billet aluminum.

The interior, too, was revolutionary. The extensive use of real aluminum to accent high-quality black plastics and leather was a trend-setting idea that, over a decade later, still looks modern and exciting. Martin Smith is credited with the TT's interior design, and his careful work created a cockpit that exuded the same brilliant sense of modernity and style as the car's outer skin.

The TT was beautiful, and it was also exciting to drive—although some of that excitement was unwanted. The Audi TT was based upon the same platform that underpinned the Volkswagen Golf, and should never have been considered a true sports car. Its price, power levels, and stunning looks, though, meant that some of its competitors were thoroughbred sporting machines like the Porsche Boxster. This led to unfavorable handling characteristics, where the TT showed that its racetrack capabilities were not in line with its striking appearance. Unpredictable oversteer prevented the TT from realizing any sporting aspirations it may have had, though it is likely that Audi always intended for the car to be more of a stylistic sensation than an accomplished track tool.

Any handling issues that the Audi TT had at its limits of adhesion were forgotten entirely in around-town driving, where the TT cosseted its pilot with the comfort, security, and unique style of a thoroughly modern vehicle.

A Roadster version of the TT, replacing the Coupe's pretty roofline and useless rear seat with a folding soft top and a polished pair of roll-over hoops, was offered after the first year of TT production. The Roadster was a sensible addition and a successful seller, adding the option of open-air motoring to the supremely stylish TT lineup.

The Audi TT was one of the first cars to embrace the technology of the new millennium in a unique and exciting manner. It may have relied heavily upon its looks to garner attention, but its bold appearance was as innovative and fresh as any other part of the car. The Audi TT proved that excitement can exist even in a modern automotive climate that is often at odds with the traditional elements of vehicular fun—and that's quite an achievement for a company that, just a few decades ago, was an unfamiliar name to most Americans.

A two-door compact sports car, the Audi TT was manufactured by Audi Hungaria Motor Kft. in Gyor, Hungary since 1998 for the German automaker and Volkswagen Group subsidiary AUDI A.G. Today the TT is now in its second generation, and both generations have been available in two car body styles; as a 2+2 Coupe or two-seater Roadster. Both versions have been built on consecutive generations of the Volkswagen Group A platform beginning with the A4. Due to the platform-sharing, the TT has identical powertrain and suspension layouts as its related platform-mates; which includes a front-mounted transversely orientated engine, front-wheel drive or Haldex Traction-based Quattro on-demand four-wheel drive system, and fully independent front suspension using MacPherson struts.

In the spring of 1994 at the Volkswagen Group Design Center in California the styling of the Audi TT began. The TT was originally unveiled as a concept car at the 1995 Frankfurt Motor Show. J Mays and Freeman Thomas were credited for the design, along with Martin Smith and Romulus Rost who contributed to the award-winning interior design. The TT takes its name from the successful motor racing tradition of NSU in the British Isle of Man TT motorcycle race. In 1911 NSU began competing in the TT, and eventually merged into the company now known as Audi. The Audi TT follows the NUS 1000TT, 1200TT and TTS cars of the 1960s in taking their names from the race.

Enabling seamless design features on the first-generation TT was a previously unused laser beam welding adaptation, but which actually delayed its introduction. In the beginning Audi didn t offer any type of automatic transmission option for TT. From 2003 though a dual clutch six-speed Direct-Shift Gearbox became available, with the U.K. TT variants becoming the world s first user of a dual clutch transmission configured for a right-hand drive car. Though the major world first for a road car equipped with a dual clutch transmission was claimed earlier by a Volkswagen Group platform-mate; the left hand drive Volkswagen Golf Mk4 R32.

With an internal designation Typ 8N, the production model was introduced as a Coupe in September of 1998, followed closely by a roadster in August of 1999. The production model was based on the Volkswagen Group A4 platform as used for the Volkswagen Golf Mk4, the original Audi A3, the Skoda Octavia and others. Compared to the concept the production model was styled only a little different from the concept, except for the slightly re-profiled bumpers, and the addition of a rear quarterlight windows behind the doors. In October of 1998 the factory production commenced.

After a series of high-speed accidents in Europe, early TT models gained press coverage. During abrupt lane changes or sharp turns crashes were reported along with related fatalities that occurred at speeds in excess of 110 mph. Late in 1999 and early in 2000, both the coupe and roadster models were recalled to improve predictability of the car s handling at extreme high-speeds. Newly added were Audi s Electronic Stability Programme, and rear spoiler, along with suspension modifications. All of the changes and updates were subsequently incorporated into future series production version of the vehicle. In June of 2006 factory production of this generation ended.

Sharing an identical powertrain layout as its related Volkswagen Group platform-mates mechanically, the TT utilizes a transversely mounted internal combustion engine, with either front-wheel drive, or quattro on-demand four-wheel drive. Initially it was available with a 1.8 liter inline four-cylinder 20-valve turbocharged engine in two states of DIN-rated power outputs; 178 hp and 222 hp. All of these engine share the identical fundamental design, however the 166 kW version features a larger K04 turbocharger, an additional intercooler on the right side, forged connecting rods, a dual tailpipe exhaust and several other internals; which were designed to accommodate the increase in turbo boost; from around 10 lbs per square inch to 15 lbs per square inch. Branded as Quattro ; Haldex Traction enabled four wheel drive which was optional on the 180 engine, and was standard on the more powerful 225 version.

In early 2003 the original four cylinder engine range was integrated with a 184 kilowatts 3.2 liter VR6 engine, which came standard with the Quattro four-wheel drive system. The following July, a new six-speed dual clutch transmission called the Direct-Shift Gearbox which improved acceleration through much reduced shift times, was available, along with a stiffer suspension.

In 2005, Audi unveiled the Coupe-only limited edition Audi TT Quattro Sport. The Quattro sport was built by Audi A.G. high performance specialist subsidiary Quattro GmbH and it featured increased power from its 1.8 liter turbocharged engine rising to 27 hp and 236 lb ft of torque. It also was reduced in weight by 165 lbs which allowed it to reach 0 to 62.1 mph in just 5.9 seconds and it had a top speed of 155.3 mph. Audi achieved this weight lot by deleting the spare wheel, the removal of the rear parcel shelf and rear seats along with deleting the standard fitment air conditioning. On the inside, the Quattro sport featured lightweight fixed-back Recaro bucket seats. You could tell the Quattro Sport from the other TT Coupes by its two-tone paint scheme and the exclusive 18 15-spoe cast aluminum alloy wheels, plus the identical body kit fitted to the TT 3.2 V6, up-rated suspension settings, black exhaust tailpipes, V6-spec brakes with red-painted calipers up front and new wheels that were wider at the rear which greatly improved handling.

The first generation TT has undergone two U.S. class action lawsuits affective specific models. In 2007, Pearson, Soter, Simon, Warshaw and Penny at LLP and the Law Office of Robert L. Starr filed a class action lawsuit against Volkswagen Group of America claimed that the timing belts for model year 1999-2003 Audi and Volkswagen cars equipped with a 1.8 liter turbocharged engine fail prematurely. The vehicles included in the suit are the Audi TT, Audi A4 and the Volkswagen Passet. The plain claims that the timing belts fail prior to the service interval, as stated in the owner s manual. In May of 2008 the parties had reached a class-wide settlement and preliminary approval of the settlement was granted by the court. Another lawsuit entered May of 2008 alleged that the instrument clusters on 2000-2005 model year Audi TTs were defective.

For 2000, the original generation Audi TT was nominated for the North American Car of the Year award. For 2000 and 2001 it was also on Car and Driver magazine s Ten Best list.

In 2005, a sneak-peak of the second-generation TT was revealed in the form of the Audi Shooting Brake concept car at the Tokyo Motor Show in 2005. The concept featured angular styling, and a shooting brake two-door hatchback body style, and was an insight into the new TT design. On April 6, 2006 Audi unveiled the second-generation TT; internal designation Typ 8J. Constructed on the Volkswagen Group A5 platform, the 2nd generation TT utilized aluminum in the front body panels and steel in the rear which enhanced its near-neutral front-to-rear weight distribution. This vehicle was available in front-wheel drive or quattro four-wheel drive layout and it was available once again as a 2+2 Coupe and as a two-seater Roadster. In comparison to the previous generation, this newest generation is five inches longer and three inches wider. In August of 2006 factory production began.

In the beginning the powertrain options only included petrol engines, which consist of either one of two inline four cylinder engines; the all-new 1.8 liter EA888 Turbocharged Fuel Stratified Injection or the more common and established EA113-variant 2.0 liter TFSI. Derived from the Audi Le Mans endurance race cars, the Fuel Stratified Injection and offers advanced power output and cleaner emissions. Brought over from the previous year the 3.2 liter V6 badged VR6 engine was also available in the Canadian model. In the 2009 model year the 2.0 TSFI Quattro models with the latest EA888 engine.

Standard on this generation was a six-speed manual transmission with the six-speed Direct-Shift Gearbox as optional for all but 1.8 liter engine. Standard on V6 models was Quattro on-demand four-wheel drive, once again using the Haldex Traction clutch, but not available on 1.8 TFSI. The new 8J TT now featured a multi-link fully independent rear suspension which complimented the front independent suspension, much like all its PQ35 platform buddies. Audi Magnetic Ride was Audis new active suspension which enhanced the entire suspension system and was available as an option. This extra feature was based on Delphi s MagneRide, a suspension which utilized magneto rheological dampers. Also new on this TT was an updated rear spoiler that automatically extends at speeds greater than 75 mph and retracts again below 50 mph. This spoiler can be manually controlled by the driver through a switch on the dash.

Debuted at the 2008 Geneva Motor Show, the 2.0 TDI Quattro is the first diesel engined version of the Audi TT in the European market. As the name implies, it is only available with Quattro, and is available in Coupe and Roadster version. Power came from the new 2.0 liter Turbocharged Direct Injection engine, now with 16 valves, double overhead camshaft, 1,800-bar common rail fuel delivery and eight-hole piezo fuel injections that produces a DIN-rated output of 168 bhp at 4,200 revolutions per minute and torque of 258 lb/ft at 1,750 to 2,500 rpm. This model also includes a six-speed manual transmission.

Acceleration was rated from 0 to 62.1mph on the Coupe in just 7.5 seconds and could reach a top speed of 140.4 mph. The Roadster was slightly less aerodynamic and reached 0 to 62.1 mph in 7.7 seconds and had a top speed of 138 mph. Audi claims that the average fuel consumption for the Cope variant with the 2.0 TDI engine is 5.3 liters which achieves a CO2 emissions rating of 139 gram. The Roadster TDI achieves an average of 51.4 mph and CO2 of 144 gram.

Audi released the first Audi S model of the TT range at the 2008 North American International Auto Show in Detroit with a heavily revised 2.0 TFSI engine. The cylinder block, fuel injectors and cylinder head were all modified from the base 2.0 TFSI engine. Along with additional modifications, this engine produces a DIN-rated motive power output of 268 bhp and generates a torque turning force of 258 lb ft of torque from 2,500 to 5,000 rpm. The S was available with a choice of either a six-speed close-ratio manual transmission or a six-speed S tronic transmission. The S tronic gearbox was the only available transmission in the United States and it was only available with Quattro four-wheel drive as standard.

The suspension in the S was lowed by 0.4 inches in comparison to the standard models and included Audi Magnetic Ride as standard and a all-new two-stage sports-biased Electronic Stability Programme . Clamped by a single-piston gloss black caliper which was embellished with a bold TTS logo was the radially ventilated front disc brakes and a lap time that was prominently displayed in the center of the instrument cluster. Standard on the S were 9Jx18 5-parallel-spoke design alloy roadwheels with 245/40 ZR18 high performance tires. 19 5-spoke star wheels and tires were optional on this vehicle. Compared to the standard model the exterior featured some updates with a TTS body styling with a newly redesigned front, redesigned rear bumper, side sill extensions, four exhaust tailpipes and larger air intakes. The TTS s Coupe performance was recorded at 0-62.1mph in just 5.4 seconds, with the Roadster just two-tenths slower at 5.6 seconds. The top speed is electronically limited to 155mph.At the 2008 Isle of Man TT motorcycle races Audi offered 8 TTS cars for official use.

At the 2008 W rthersee Tour at P rtschach am W rthersee in Austria Audi debuted a new show car variant of the second generation Audi TT; the TT Clubsport Quattro. It was shown only in an open-topped speedster variant, and its 2.0 TFSI engine was tuned to give 296 bhp. The soft top from the standard TT Roadster disappeared and was replaced with two humps , along with two substantial roll bars. The Clubsport Quattro featured LED daytime running lamps, black-painted single frame grill , an aggressive body kit with large frontal air intakes and a lower spoiler lip. The axle trip was widened 2.6 inches with bolder and wider wheel arch extensions, wider side sills, polished 19-inch alloys and 255-section tires, and the rear were twin polished stainless steel oval tailpipes next to a new rear diffuser.

On the inside the Clubsport Quattro featured racing bucket seats, a six-speak S tronic dual-clutch transmission with Quattro four-wheel drive, TTS spec brakes and lightweight aluminum detail throughout the interior. Though Audi has not ruled out the possibility of a small scale production, it was primarily a show car .

Debuted at the 2009 Geneva Auto Show, Audi released the first ever compact sports car Audi RS model; the new Audi TT RS which was available from 2009 in Coupe and Roadster variants. Developed by Audi s high performance subsidiary Quattro GmbH at Neckarsulm, the new TT RS harks back to the sporting legacy of 1980s Audi Quattros with their high performance five-cylinder turbocharged engines. The TT RS included an all-new 2.5 liter inline five-cylinder Turbocharged Fuel Stratified Injection petrol engine which produced a DIN-rated motive power output of 335 bhp from 5,4000 to 6,700 rpm and a torque of 450 newton meters at 1,600-5,300 rpm.

The Audi RS2 Avant and all Audi RS models afterwards were assembled at the Quattro GmbH factory in Neckarsulm, Germany.

Featuring a new short-shift close-ratio six-speed manual transmission the TT RS is only available with Audi s trademark Quattro four-wheel drive system, like all RS models. The TT RS utilized a specially adapted version of the latest generation multi-plate clutch from Haldex Traction. The Quattro system included addition like a constant velocity joint before the cardan propeller shaft and a compact rear-axle differential that was up-rated to cope with the increased torque from the five cylinder turbo engine. The TT RS featured a 0.4 inch lower ride height like the TTS and featured optional Audi Magnetic Ride and rides on a standard 18 inch road wheels with 245/45 ZR18 tires. The front discs on the TT RS are clamped by gloss black painted four-piston calipers which featured the RS logo and the braes were up-rated to include two-piece cross-drilled and radially vented front discs sized at 14.6 inches in diameter. The rear ventilated discs were 12.2 inches in diameter.
