History

The little AC company Of Thames Ditton in Surrey their factory was at Thames Ditton, only a few miles away from the famous Brooklands Track. S.F. Edge, the famous pre-war Napier salesman, joined the firm in 1921. He went about building a more racing image for the company, first starting with a team of six cars in the 200 Mile Race at Brooklands.
Making a name at Brooklands .Although all had racing bodies, three of the 1921 team cars used fairly standard side valve Anzani engines, while the Other three had single-ohc units derived from the company's six-cylinder engine. With 16-valve heads they gave 42 bhp, but all three retired. AC's best place was Stead's 8th in aside valve car. In June, 1921, at Brooklands, Hawker covered the flying half-mile at 105.14 m.p.h. and same distance from a standing start at 61.43 m.p.h., both of which were world-class records. In 1922 the Ohc cars failed again, but this was compensated by successes in record breaking.

An aircraft maker's body One of the AC drivers was the famous pilot and aircraft manufacturer Harry Hawker, and most of the racing cars of the early 1920s carried bodies made by his company at nearby Kingston-on- Thames. A.C. put polished aluminium airship-tail sports bodies designed by Weller that were highly streamlined, they had aluminium panelling on wood frames in 1992 a particularly low-slung car was made with cowled radiator and a 16-valve engine tuned to give 55 bhp. With this car J.A. Joyce drove 101 miles 696 yards (163.04 km) in one hour. This was the first car under 1.5 litres to cover more than 100 miles in one hour.  The car returned to the works, where power output was pushed up to 64 b.h.p. and Kaye Don then covered just over 94 miles in the hour. A team was formed by the works to have a crack at the Double-12 and 200 miles Brooklands races, but although they won their class in the 1922 Double-12 race at a record average of 71.23 m.p.h., in general, the team cars suffered from lack of adequate preparation for the longer events.
