Louis Chevrolet
Also in 1916, American Motors Corporation (unrelated to the later American Motors created by the 1954 merger of Nash-Kelvinator Corporation and Hudson Motor Car Company) was formed in Newark, New Jersey, with Louis Chevrolet as vice president and chief engineer. By 1918 it was producing cars in a plant at Plainfield, New Jersey. In 1923 it merged with the Bessemer Motor Truck Company of Pennsylvania into Bessemer-American Motors Corporation, which lasted less than a year before merging with the Winther and Northway companies into Amalgamated Motors. The latter company apparently ceased soon after.
Vector Motors
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 supercars. When founded, Vector represented America's first attempt to compete with European performance car manufacturers like Ferrari, Lamborghini, and Lotus. Altogether around 50 Vector supercar models were developed and produced during the 1980s and 1990s including some racing versions mostly built using American made components.
