The Brooklands Race Track at Weybridge is best remembered for monstrous cars powered by aircraft engines and driven by wealthy landowners and businessmen, such as John Cobb and Count Louis Zborowski. However, smaller cars were popular - the M.G. Midget and the Austin Seven being well-known. Enthusiasts with limited means would build tiny specials fitted with motorcycle engines. The Brooklands authorities catered for this diversity by defining a number of vehicle classes, based on engine capacity.
