The W8 was essentially an upgrade of the same company's earlier prototype, the Vector W2. The semi-aluminum monocoque chassis was epoxy bonded and riveted with an aluminum honeycomb structure floor pan, and 5,000 aircraft specification rivets were used in the car's assembly. Everything on the Vector was designed to last the life of the owner, assuming reasonable maintenance.[citation needed] The body was made largely of lightweight carbon fiber and Kevlar, known for its strength, and lightness.[2]The car was based around a Rodeck Aluminum resleevable, 365 cu. in. racing engine coupled to very highly modified Turbo Hydro 425 General Motors three-speed automatic transmissions that had been used in front wheel drive Oldsmobile Toronados dating back some two decades earlier. The engine had intercooled twin-turbos, and produced an advertised 625 bhp (466 kW) at 5700 rpm and 649 lb·ft (880 N·m) of torque on 8 lbs of boost. Boost levels were driver adjustable between 8 and 14 lbs and during dyno testing at the factory the engine put out 1200 bhp at 14 lbs of boost.[1]
