WAHEY!!! Can't wait.
Place your bets........
Assuming they are both stock, I expect that it will be very close. The RS4 weighs less so might get the jump, although I'm sure that the RS4 revs quite highly and doesn't produce as much torque as the M5 so it might be very close indeed.
I wouldn't expect the extra 14bhp that the RS4 has over the E39 to make many odds at higher speeds. Anyone know the drag co-efficients of them both?
M5 (i) - Le Mans Blue, 218,000 brilliant miles before rust and head gasket failure killed it.
M5 (ii) - Carbon Black, 140,000 miles and counting.
