All good, but how they say; look at a slightly tuned m5 vs stock rs4.
So in theory if you did the same modifications to the rs4 it would then once again be faster than the m5.
Isn't that saying like; with a few modifications this Accord can take the .:R32?

the RS4 Avant would be sick though, see them M5 owners getting beat up on by wagon ;)

but, the truth on your statement is, M5 is RWD and RS4 is AWD

the reason the Audi losses over 120mph is because AWD has double the drivetrain loss ... on top of that, as you go faster, drivetrain loss increases ... therefore, the problem is, top speed is highly effected at top speeds ...

the M5 will dominate 100mph + even with lil power mods

and also, the SuperSprint exhaust, cat, header upgrade + software has dyno'd about 40hp increase ... so thats not a good comparison
