Speedwell Stable

Speedwell Stable was a British racing team based in London. The team was formed by racing enthusiasts John Sprinzel, Len Adams and George Hulbert in 1957.

Speedwell were one of the leading saloon car teams in the early years of the British Saloon Car Championship, having competed in the inaugural season in 1958. The team ran a pair of Austin A35s for Sprinzel and Adams (although Adams' car was entered under the Bray Motors Ltd. banner) and were among the top contenders in class A. Formula One star and Speedwell engineer Graham Hill took part in the Silverstone round when Adams was unavailable, winning the class.
