The Vector W2 is a concept car constructed by Vector Motors in 1978. The concept went into production as the Vector W8 in 1990. The name comes from the "W" for Jerry Wiegert (designer and founder of Vector Motors) and "2" for the number of turbochargers. The car is fully functional. It has a Bosch fuel injected twin-turbocharged 350 cid (5.7 L) aluminum Chevrolet V8 engine that producees over 600 hp (450 kW) and over 600 ft·lbf (800 N·m) of torque. The top speed is a claimed 242 mph (389 km/h). The car went through a number of improvements in performance, technology, updated styling exercises, as well as color changes. It was displayed at international auto shows worldwide, and featured in many automotive publications. The car covered over 100000 mi in testing, more than any other concept car. In 1990, the concept went into production as the Vector W8. Only a handful cars were constructed before the company went bankrupt. Currently, the Vector W2 prototype is inoperable, but is slated for restoration.
