From a practical standpoint, does the M3 outrun the corvette b/c of it's torque advantage? I haven't paid attention to acceleration numbers b/c I have started to just think of cars as "fast" "not so fast" and "slow." I have come to realize that, unlike some of you, shaving a half a second off a one minute autocross course doesn't mean anything to me and there are a lot more important factors that go into car choice than 0 to 60 or quarter mile times.
It's all gearing. I'm assuming that JV ignored drivetrain losses (which should be about the same in two front engined, RWD cars anyway).

The M3 has shorter gearing and more revs to work with.
