Re: 2009 Nissan GT-R Top Speed
Exactly, once mass is in motion - it's in motion. Hell, the mass helps it stay in motion once up to snuff.
If Nissan could find a way to shave 300-400lbs out of the car, and still make it road legal with making it obscenely expensive, I'd be scared to think of the performance benchmarks it could set for a production homologated machine.
And yep Trip, the GT-R's odd shape and bumps actually contribute to a very low CoD.
