The Avon Tyres British GT Championship (previously known as the BRDC GT Championship) is a sports car racing series based in the United Kingdom, although selected races do take place outside of the country.
 The series was originally created by the British Racing Drivers' Club in 1993 and, for its first two seasons, was known as the National Sports GT Challenge.

 The GT3, introduced in 1999, is named after the Fédération Internationale de l'Automobile (FIA) Group GT3 class, created in 2005, in which it was designed to compete.
Embassy Racing was a British auto racing team founded by Jonathan France in 2003.
 Initially created as a conjunction with Xero Competition in the British GT Championship, the team expanded to become an independent team and began to win races in British GT before the team took a sabbatical year in 2006.
 Upon their return to motorsport, Embassy moved to the international Le Mans Series, running in a Le Mans Prototype class, as well as entering the British Superbike Championship's junior leagues, the Supersport and Superstock Championships, running with the support of Triumph Motorcycles under the MAP Embassy Triumph banner.
The McLaren F1 GTR was a racing variant of the McLaren F1 sports car first produced in 1995 for grand touring style racing, such as the BPR Global GT Series, FIA GT Championship, JGTC, and British GT Championship.

The 2017 British GT Championship will be the 25th British GT Championship, a sports car championship promoted by the Stéphane Ratel Organisation (SRO).

The 2006 British GT season consisted of a fourteen-round series of sports car racing in the British GT Championship.
 The season consisted of two 2-hour enduros at Donington Park and Silverstone, with 4 other double 1 hour-race events held in England, 2 in France (held alongside the FFSA GT Championship) and 1 in Ireland.
 It was contested by GT2 cars, the renamed GT3 class (now GTC), and a new GT3 class conforming with new FIA regulations.
 This would be the last year of competition for GT2 cars, with very low grids and thus half points being awarded at most races.
 The following year, GT3 became the main class, with GTC supporting.
