Vector Motors Corporation is 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 like 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.

Nearly every car produced by the company is designated the letter "W" (for Wiegert) and a number. A letter "X" after the W (e.g. WX-8) signifies a prototype unit.

In August of 2018 it was reported that the company was still actively developing an entirely new vehicle, the WX-8, a vehicle positioned in the colloquially named "hypercar" category, which it first announced and presented a prototype model of back in 2007.

Founder, principal owner, chief executive, lead designer and engineer Jerry Wiegert died in January of 2021 aged 76, leaving the fate of the company and corporate entity in question.
