Audi's philosophy is "advancement through technology" and that's not something found lacking in the TTS. The engine is based on the highly-revered 2.0-liter, four-cylinder, turbocharged TSFI unit. Featuring direct injection, the powerplant contains a host of modifications over the standard motor (as installed the {{{Volkswagen GTI}}}, among other vehicles), including a beefier engine block, cylinder heads, and connecting rods. The turbocharger is new too -- able to produce up to 1.2 bar of air pressure -- and intake and exhaust systems have been optimized for both increased performance and increased aural delight. A revised intercooler lowers the temperature of the intake charge to maximize the amount of air flowing into the engine.

The result is a whopping 72-horsepower and 51-lb-ft increase over the standard 2.0 TSFI unit, for a total of 272 horses and 258 lb-ft of torque. All that power is sent through Audi's Quattro four-wheel drive to each wheel, resulting in a 5.2 second 0 to 62 mph dash (the Roadster lags just 0.2 seconds behind due to its slightly less aerodynamic profile). Keep the throttle pegged and the TTS' computer will stop you at a top speed of 155 mph whether your roof goes down or not. The TTS will only be available in the U.S. with Audi's version of the dual-clutch DSG transmission, the S tronic. But fear not, Audi claims that transmission provides for faster acceleration times than the manual box that's standard in Europe.
