Nope, take it on a track, the m3 is going to beat it by just a little.
The corvette's top speed (from factory) is, i believe, 36 miles per hour more than the M3. The m3 has short gear ratio's for it's higher end, which is why on a track, the M3 will accelerate faster out of corners than a Vette.
I mean, don't get me wrong, I think the vette is awesome, but just because it is fast, doesn't take away the fact that it's made by GM, with (recent) GM quality [thumbd]
