Even more eye-catching than the coupe, the second-generation TT roadster is a more aggressive, muscular car than its predecessor. Competitors such as the BMW Z4, Mercedes-Benz SLK, and Nissan 350Z offer more performance, but the only the TT inspires slavish imitation. 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.

The second generation TT features all-new styling and larger proportions. The TT is 2 inches wider in track and wheelbase, and almost 5 inches longer in overall length. Front-wheel-drive entry-level TT models are powered by a 200hp 2.0L turbocharged four cylinder. Uplevel models feature all-wheel-drive and a 3.2L V6 engine.
