Silverstone Circuit
Silverstone is the current home of the British Grand Prix, which it first hosted in 1948. The 1950 British Grand Prix at Silverstone was the first race in the newly created World Championship of Drivers. The race rotated between Silverstone, Aintree and Brands Hatch from 1955 to 1986, but relocated permanently to Silverstone in 1987.
2000 Silverstone 500 USA Challenge
This event was the first American Le Mans Series race held outside of North America. It served as a precursor to the creation of the European Le Mans Series by gauging the willingness of European teams from the FIA Sportscar Championship and FIA GT Championship to participate in a series identical to the American Le Mans Series. This event also shared the weekend at Silverstone with an FIA GT round, with some GT teams running both events.
