The Audi TT was originally defined by its distinctly curved styling. Now in its second generation, the TT wears more traditional styling around its compact dimensions. The TT is offered as both a 2+2 hatchback coupe and a 2 passenger roadster. Most TT models are powered by a 211-bhp turbocharged four cylinder engine and include a six-speed dual-clutch automated transmission and quattro all-wheel-drive. The higher performance TTS models increase the output of the four-cylinder to 265-bhp. The roadster's fabric top is fully power-actuated and fits over the rollover hoops behind the seats. The TT is similar in size to other small convertibles like the BMW Z4 or Nissan Z. With pricing that overlaps the larger A5 coupe/convertible, the TT is a niche vehicle aimed at a buyer looking for something unique.
