Audi TTS

2008 Audi TTS
Audi Press Release

Audi TTS 2008Audi 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-litre TFSI high-performance engine delivering a mighty 200 kW (272 hp). 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 (272 hp), 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-litre 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 litres of fuel per 100 kilometres (29.375 mpg) in the Coupe when partnered by the six-speed manual transmission, while the figure for the roadster averages 8.2 l/100 km (28.659 mpg). These figures are improved by 0.1 and 0.2 l/100 km (by 0.372 and 0.716 mpg), respectively, if the optional S tronic dual-clutch transmission is fitted.

Audi TTS 2008S 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 millimetres
(0.39 in) – to deliver uncompromisingly dynamic handling. Its front suspension is mainly made of aluminium, 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 aluminium. ASF (Audi Space Frame) technology optimises axle load distribution and reduces the overall weight. The manual Coupe weighs just 1,395 kilograms (3,075.45 lbs), which equates to a power-to-weight ratio of 5.1 kg/hp (11.24 lbs/hp).
