The World Championship is an annual competition started in 1955 for BriSCA Formula 1 Stock Cars.
The host tracks, all of which are based in the UK, are decided by the BriSCA promoters.
Drivers who fail to progress from the World Semi-Finals may race again in a Consolation Semi-Final to choose two more entrants, and the reigning World Champion is entitled to start at the rear of the grid if they have not already qualified.
The most successful driver in World Final races is John Lund, who has won eight.
Other notable multiple winners include Stuart Smith (six), Andy Smith (five), Peter Falding (four) Tom Harris (five), Johnny Brise, Dave Chisholm and Frankie Wainman Junior (three).
