I've been checking back at this website for a couple years now and thought you guys might be interested. This guy has been using CAD to design an AWD, 800lbs 400hp car for years and just recently finished building and drove it for the first time. The (future) motor is a custom block V8 with a pair of Hayabusa heads. The thing is ridiculous.
Check it out.
Oh, and DP is the guys initials. Not what he loves doing to women. :-\
