Audi are diluting the TT brand a lot though, they're also bring out a 1.8T as well. The TT TDi will soon be on company car lists everywhere, a bit like the 2.0 Z4 is/was.
I don't especially mind diesel engines, but the problem with most of them is that they are dead below 1800rpm, explosive between 1800-3600 and then the power tails off drastically above that. The performance is also usually blunted by exceptionally long gearing, so although they have a lot of torque at the crank, the torque at the wheels is usually little different to equivalent petrol models.
At least the TT is 4WD.
