With snazzy styling and peppy performance, the Audi TT and TTS appeal to both the practical and the passionate. The TT has a 220-hp turbo four; the TTS makes 292 hp. Quattro all-wheel drive and a six-speed dual-clutch automatic are standard on both models; a manual, unfortunately, is not offered. The TT is available as both coupe and softtop; the TTS only as a coupe. With well-tuned suspensions, the TT and TTS are effortlessly fast. They blend style with refinement in ways the competition doesn't.
