Officially unveiled at the Geneva Motor Show on Tuesday, the third generation Audi TT is, visually at least, a gentle evolution of the outgoing model.

However, there are huge changes under the skin.

That's not to say the new car looks identical; it's more angular and masculine especially at the front where the grill is very similar in design to the one found on the range-topping R8 supercar. Yet it's still unmistakably a TT.
