The Austin A30 is a compact economy saloon produced by the British Motor Corporation under the Austin marque, manufactured from 1951 to 1956. It was the first car to carry the A-Series engine, a small overhead-valve four-cylinder unit that would go on to power decades of British cars including the Mini. The A30 was sold primarily as a two-door or four-door saloon, with an estate variant called the Countryman also offered. It was succeeded by the closely related Austin A35, which retained the same basic bodyshell with mechanical improvements.
