Whats the C63 1/4 mile time?Still a walk in the park.
The current crop of Audis have been on a diet but nothing significant - in fact it's only just brought them in under the C63!
Let's compare the current (2.9 V6 TT) and slightly older RS4 (4.2 V8 FSI) with the OP's C63 running a genuine 615BHP.
C63
1730KG / 615BHP = 355BHP per ton
RS4 (Current)
1715KG / 450BHP = 262BHP per ton
RS4 (Just before current)
1795KG / 450BHP = 250BHP per ton
No amount of cornering ability / handling will help when the C63 is miles ahead in the distance!
If all cars are standard, it's a different story as the power is much closer.
