Hi Yannis,How are you?

The rumors i have red on the net tell about a 4.2FSI engine (high revs: 8250rpm/8300rpm) with 2 small turbos at low pressure (like the 335i) and, maybe with variable geometry system (like the 997 turbo).
So power will be increased to a minimum of 450 PS. But the very interesting point is the torque: a minimum of 600nm: a mighty thrust in every condition.

The second important point is the QVT. This new generation of "quattro" will be lighter,faster and less expensive in terms of engine's power absorbed by the 4x4.

The engine situated in a better (like the A5) position will decrease the understeer tendency.
