Great! New TT models....
Umm... I think the TDi is a good addition, although I think the 123d will still trounce it - I can imagine that diesel 4 being very loud, not sure about the TTRS, I personally think that it's too close to the R8 and I really think it needs real-wheel-drive. TTS - good, but we all know it'll be nowhere near the Cayman dynamically...
Note to Audi, how about a high revving 1.8 FSI 4? With about 180bhp @7500rpm and maybe 160lb/ft@ about 3500 rpm?? If they want a "motorsport" feel, this is the only way to go. Keep it simple.
