My favourite is the 5 pot 2.2, an innovative engine used in so many applications .

For me is the 4.2 Bi Turbo in the RS 6...made with Cosworth I believe ?

Supercar power when it was released back in 2002 and still up there with the best 8 years later

The 4.7 L, Audis first 6 cylinder engine, not bad for 1924

I was lucky enough to have one of these beasts for a short while.... so effortless, so unburstable Incredible used car bargains at circa £25k.

Predates any BMW or Porsche engine

!5.0 V10 Bi-Turbo 580bhp (or 700bhp chipped etc.)!

Drives like a 200mph TGV (fast effortless,precise,comfortable), and probably could pull a train.
