Sheridan Motor Car Company, produced in the United States from 1920 to 1921, was a short-lived automobile manufacturer based in Muncie, Indiana and notable for being the first automobile brand created from scratch by General Motors rather than acquired by it. Developed under the leadership of William C. Durant, the brand offered four-cylinder and V8 passenger cars positioned between Chevrolet and Oakland, and between Buick and Cadillac, respectively. Promoted by racing legend Eddie Rickenbacker, Sheridan was intended to become a major GM marque, but Durant's departure from General Motors led to the project's cancellation. The brand ceased production in 1921 after approximately one year, making Sheridan one of the rarest and shortest-lived marques in American automotive history.
