The Dunlop MSA British Touring Car Championship withdrew the track from its calendar in 2007. Strong demand brought the series back to Silverstone for the 2008 BTCC calendar. Silverstone also hosts rounds of the FIA GT, British Superbikes, British F3, British GT and Le Mans Series championships as well as many club racing series. It is also host to the UK's only 24-hour car race, the Britcar 24, which is gaining in popularity, having first started in 2005.
