Autogear was a British automobile brand established in 1922 by Foster Engineering Co. Ltd, located in Letchworth, Hertfordshire. The company produced a conventional light car that was powered by a 7 horsepower flat-twin engine. This vehicle featured a friction transmission system, which was a notable characteristic of its design.

To differentiate itself from another manufacturer producing vehicles under the same name in Leeds, the car was sometimes referred to as the Foster. Additionally, it was known by another name, Accelera, which was used interchangeably in various contexts.
