I cut this from another site, and he makes some good points
The best thing about Vector was some of the people it used to hire and have as consultants. People that have been through those doors have designed such cars as the McLaren F1, Shelby Cobra, 935's, numerous Ferraris, BMWs, Indy, F1 cars, etc.
The worst thing about Vector is that management could never decide what to do with a car like this in a dwindling market, and the fact that Weigert hired morons to just answer yes to him and never improve the car. But it was a hell of publicity campaign while it lasted. You add it up, 15 years, 40-50 million dollars, and only 15 cars ever built. The original engine was a 6 liter V-8 with twin H-3 turbos. This engine was good for 600-620 HP max non emissioned, and 530-550 Hp max with 1992 emission standards.
The Vector could never do 207, and 250-260 is just ludicrous. A slippery Porsche 916 with 1200+ Hp could barely manage mid 240's. And the Vector has probably 50% more frontal area. Max velocity for the W-8 168 mph, period. Weigert would never change his brick-in-the-wind design, so the car was stuck with a .55 coefficient of drag (considering the average Kenworth in new plastic is a mere .43 cd).
The old W-8 and the WX-3/M12 prototype shown, have curb weights of 3700 lbs. The WX-3/M12 prototype which has been in Newsweek is an old W-8 prototype in some new glass with the same old V-8 engine and chassis, not a new car.

Mistake #1- He should have not given that car to piss-head Agassi like that.
Mistake #2- He should have designed that car better, the front end was draggy as hell. And he always claimed it could do 250 mph.
Maybe he was a talented designer and inventor, but it looks to me like he was too pig-headed to take advice from the other designers and he ultimately failed.
