C5 Z06 0-150mph 25.5 sec
E90 M3 0-150mph 24.9 sec

The C5 Z06 has lousy aerodynamics compared to the coupe, which explains how and why it comparatively tails off a bit at speed, compared to the M3 (and the current C6, at 23.5 seconds), At, say, a 75 mph cruise based on the OP, aerodynamics is nothing.

So, you're saying that at 75 mph, power to weight is unimportant, and aerodynamics and gearing rule? OK, first things first: I agree that power to weight matters most at a stop, and least when you're approaching top speed.
But, 75 mph? At that speed, the M3 probably needs about 40 hp to cruise, and the Vette, maybe 45? Everything you're making over that is available for acceleration.
Gearing? I don't get it. How does gearing affect all this in the slightest? I get that, at 75 mph, the M3 is at around 6000 rpm in third, making around 320 hp. The Vette is at around 4700, making around 350 hp.
How does gearing trump hp?
