Vector W8
Never heard of the Vector W8? It’s only the craziest supercar as of yet, manufactured between 1989-1993, and inspired by the Alfa Romeo Carabo, which had a futuristic aerodynamic design. This supercar basically merged the design characteristics of the Carabo with technologies and geometry from fighter jets of the era, while utilizing the most advanced aerospace materials.

The vehicle was powered by a Rodeck aluminum resleevable 6.0L racing engine producing 625 hp and 649 lb⋅ft of torque on 8 psi of boost pressure. the engine featured TRW forged pistons, Carrillo stainless-steel connecting rods, stainless-steel valves, roller rocker arms, a forged crank, a dry-sump oiling system with three separate filters and braided stainless-steel hoses, mated to a highly modified Turbo-Hydramatic 425 General Motors three-speed automatic transmission.

Vector claimed the W8 could achieve a top speed of 242 mph and accelerate from 0–60 mph in just 3.9 seconds. During testing at the Bonneville Salt Flats, the W2 prototype reached a maximum speed of 242 mph with a Donovan aluminum block engine that was less powerful than a production W8’s engine.
