    How does Audi follow this? I can't imagine packaging 3 turbos into a v6 is easy - BMW has the advantage of an inline 6 here. Also, I'd always take a lighter 3 turbo 6 cylinder over a v8 any day.

    My french isn't brilliant but the most interesting bits for me, if I understand it correctly, were the mention of the 300bhp v6 tdi and a petrol v8 that can shut down 4 cylinders to save fuel

    Wow, that's the highest stock reading I've seen. makes me think it's a bit unlikely.

    Thanks guys - very informative. No mention of efficiency/drive train losses though. You'd hope, being newer, that there would be less power loss than the old torsen?

    The red car on the Geneva stand looks great. The squared off wheel arches are quite subtle - maybe they stand out more in a different colour or when you actually see the car in the flesh.

    The heart of the problem here seems to be when the RS5 is released. I had a similar problem in that I wanted a new RS4 but decided to get an S4 until the RS4 arrives. The difference is that I knew...

    Completely agree with you. Having done the MTM upgrade, my S4 is now RS4 quick but it doesn't have the character. If the B7 RS4 had more space in the back I'd take it over the new S4 every time.
