The Vector W8 is a sports car produced by American automobile manufacturer Vector Aeromotive Corporation from 1989 to 1993. It was designed by company founder and chief designer Gerald Wiegert while receiving refinements by Vector's head of engineering David Kostka. The W8 was the production version of the Vector W2 prototype that the company demonstrated throughout the 1980s.

Vector Motors Corporation was an American automobile manufacturer originally based in Wilmington, California. Its history can be traced to Vehicle Design Force, which was founded in 1978 by Gerald Wiegert. Vehicle production by Vector Aeromotive began in 1989 and ceased in 1993. The company was later revived as Vector Motors Corporation, and has continued to develop sports cars. When founded, Vector represented America's first attempt to compete with European performance car manufacturers such as Ferrari and Lamborghini. Altogether around 50 Vector sports car models were developed and produced during the 1980s and 1990s including some racing versions mostly built using American made components.
