The 2009 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 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 with this engine. The all-wheel drive version can also be had with a 250-hp 3.2-liter V6 with the choice of a six-speed manual or a six-speed S-tronic transmission. 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 2009 include the availability of the 2.0T engine with the quattro AWD system as well as new packaging of different trim levels.
