Austin 10 hp

The Austin 10 hp is a high-quality small car (not cycle car) produced between 1910 and 1915 by the British car manufacturer Austin Motor Company Limited at their Longbridge, Worcestershire plant near Birmingham. 1,336 cars were made, 213 with the 1125 cc engine and 1,123 with the 1615 cc engine. Like the 1087 cc Austin 7 hp produced by both Austin and Du Cros's Swift Motor Company it was not very successful when sold with the small engine.

The original small 4-cylinder 1125 cc engine was replaced in 1913 with a larger 14.32 horsepower 1615 cc engine. Though rated for tax at 14.3 horsepower this larger engined model is sometimes referred to as the Austin 10/12.

In 1913, the 10 hp was the cheapest model in the Austin range, costing £260 for a chassis with tyres. The 10 hp (of 14.32-h.p.) was renamed 12–14 hp before midsummer 1915 but production was limited due to the war.
