Vector

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 began in 1989 and ceased in the 1990s. The company was recently revived (as Vector Motors Corporation), and is currently developing a new supercar. Vector is credited by some as America's first attempt to compete with European performance car manufacturers like Ferrari, Lamborghini, and Lotus. 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. The only exception to this rule is the Megatech-era M12, wherein the "M" stands for Megatech and the 12 signifies its V12 engine.
