Autovia (United Kingdom)

Autovia Cars Ltd was a British automobile manufacturer established in Coventry in 1936. The company was formed by the Riley company with the intention of producing luxury vehicles that occupied a higher price bracket than existing models. Autovia utilized a development of Riley's V8 engine, which was enlarged to 2,849 cc and produced 90 bhp. The cars featured a long frame with an underslung worm drive, and most were equipped with Armstrong-Siddeley 4-speed pre-selector gearboxes, although some later models included all-synchromesh 4-speed units.

The company acquired a new factory and was led by directors including Victor Riley and designer Charles Van Eugen, who had previously worked with Lea-Francis. Autovia aimed to emulate the practices of high-end manufacturers like Rolls-Royce, even establishing a chauffeurs' school. The brand offered two main bodystyles: a 4-light sports saloon and a 6-light limousine, with bodies constructed by Arthur Mulliner, and at least one example bodied by Wmdover.

Despite its ambitions, Autovia faced challenges in the market, particularly due to its pricing, with the saloon priced at £975 and the limousine at £995. The company struggled financially, and following Riley's receivership in February 1938, which occurred before the Nuffield takeover, Autovia ceased operations. Approximately 35 vehicles were produced during its brief existence, and a dedicated club for the make continues to exist, separate from any Riley club.
