Even more eye-catching than the coupe, the second-generation TT roadster is a more aggressive, muscular car than its predecessor. Audi equips the TT with a choice of a 2.0L turbo or a 3.2L V-6. The V-6 can be mated to a 6-speed S tronic automatic gearbox or a 6-speed manual driving all four wheels. The FWD 2.0L gets the S tronic transmission only. Compared to the TT Coupe, the slightly heavier Roadster seats only two passengers, so interior storage suffers. The Roadster's fabric top is fully power-actuated and fits over the rollover hoops behind the seats. A comprehensive option list includes nine different alloy wheels designs (17 to 19-inches), special leather interior trim, S line sports package, DVD navigation, and Bose audio system.

An S performance model joins the TT coupe and convertible lineup. The TTS is powered by a 265-bhp, turbocharged 2.0L four-cylinder engine. All U.S. models will be equipped with the S-tronic sequential manual and quattro AWD. The TTS will also employ a magnetic ride damping system. Quattro AWD is now available with the base 2.0l engine. A manual top becomes standard on 2.0L models with the power top as an option.
