Formula racing

Formula racing is a term that refers to various forms of open wheeled single seater motorsport. Its origin lies in the nomenclature that was adopted by the FIA for all of its post-World War II single seater regulations, or formulae. The best known of these formulae are Formula One, Formula Two, and Formula Three.

Common usage of "formula racing" encompasses other single seater series, including the GP2 Series, which replaced Formula 3000.Categories such as Formula Three and GP2 are described as feeder formulae, which refers to their position below Formula One on the career ladder of single seater motor racing.

There are two primary forms of racing formula: the open formula that allows a choice of chassis and/or engines; and the control or "spec" formula that relies on a single supplier for chassis and engines. Formula Three is an example of an open formula, while Formula BMW is a control formula.

In the process of reviving Grand Prix racing after the end of World War II, the Fédération Internationale de l'Automobile's Commission Sportive Internationale was responsible for defining the standardised regulations of Formula One in 1946. The first race to be run to the early Formula One regulations was a non-championship Grand prix at Turin in September 1946. The first officially recognised Drivers' World Championship was held in 1947 and the Formula One World Championship was inaugurated in 1950. This was the first example of formula racing.
