It is simply traction limited at these speeds as most cars with a similar much power to weight ratio. M-DCT will absoultely help but it will only help in 0-60 if they get the launch control software perfect (and hopefully offer it in the US as well). Again my comments about the AWD RS4 are appropriate - faster than similar cars by quite a bit in the lower speeds but losing out at higher speeds due to high drive train losses.

Actually they are dead on with the 40,000 miles, they are not dead on with the brand new figures. You're right 4.7-4.2 is not 0.4, that's why i said around 0.4(0.3,0.4,0.5).
My point is, your figures with e46 M3 to 60 @4.5 and you Cartest results of 4.84 is a diifference of 0.34, and that's acceptable. Should'nt the 4.7 and 4.2 difference of 0.5 on the ISF results be acceptable as well? In other words, there is a margin of error. I don't think it's necessarily an exact science. In terms of the RS4, remember it is close to 200lbs heavier.
