The Audi TT is the entry-level sports car in the Audi/VW AG selection of performance cars, and is aimed directly at the segment leading cars from BMW and Porsche.

The TT blends the original Bauhaus styling with Audi's current modern design theme and advanced technology. The coupes spaceframe is 69% aluminum and 31% steel (roadster = 58/42%), with most of the steel in the rear to offset the weight of the engine and better balance the car. All TT's are all-wheel drive and are powered by a 200-hp turbocharged direct-injection 2.0-liter four-cylinder with a six-speed automatic S-tronic as the only transmission choice. Safety features include front, side and knee airbags, run-flat tires with pressure monitoring and 4-wheel anti-lock brakes and stability control.

Changes for 2010 include the elimination of the front-wheel drive and 3.2 models, new standard features such as a power top on the roadster, Bluetooth and HomeLink.
