Audi S5 (8T) 2007-2015

[Commodore GS/E]

The old Audi RS6 already has more power than the current M5...

Given that 80's F1 cars mobilized more than 1000 hp from tiny four-bangers, they still have enough room for more power. Ask AMG. They'll always find more.
But as we all know, the question is not "power", but "power to weight". And that's where it all fails.

Bah, everyone knows that sports saloons reached the peak with the E39 M5.

And in any case, it's a sports saloon, not a sportscar, so the key is not power to weight, but being an all rounder. Kind of the bigger more exepnsive brother of the hot hatch.
