Formula One, abbreviated to F1, is the highest class of auto racing defined by the Fédération Internationale de l'Automobile (FIA), motor sport's world governing body. The "formula" in the name is a set of rules which all participants and cars must meet. The F1 world championship season consists of a series of races, known as Grands Prix, held usually on purpose-built circuits, and in a few cases on closed city streets. The results of each race are combined to determine two annual World Championships, one for drivers and one for constructors.

History

The Formula One series has its roots in the European Grand Prix Motor Racing of the 1920s and 1930s. The "formula" is a set of rules which all participants and cars must meet. Formula One was a new formula agreed after World War II in 1946, with the first non-championship races being held that year. A number of Grand Prix racing organisations had laid out rules for a World Championship before the war, but due to the suspension of racing during the conflict, the World Drivers' Championship was not formalised until 1947. The first world championship race was held at Silverstone, United Kingdom in 1950. A championship for constructors followed in 1958. National championships existed in South Africa and the UK in the 1960s and 1970s. Non-championship Formula One races were held for many years but, due to the rising cost of competition, the last of these occurred in 1983.
