Formula One Formula One (also Formula 1 or F1 and officially the FIA Formula One World Championship) is the highest class of single-seat auto racing that is sanctioned by the Fédération Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been the premier form of racing since the inaugural season in 1950, although other Formula One races were regularly held until 1983. The "formula", designated in the name, refers to a set of rules, to which all participants' cars must conform. The F1 season consists of a series of races, known as "Grands Prix" (from French, meaning grand prizes), held worldwide on purpose-built F1 circuits and public roads.
Open-wheel car An open-wheel car (formula car, or often single-seater car in British English) is a car with the wheels outside the car's main body, and usually having only one seat. Open-wheel cars contrast with street cars, sports cars, stock cars, and touring cars, which have their wheels below the body or inside fenders. Open-wheel cars are usually built specifically for racing, frequently with a higher degree of technological sophistication than in other forms of motor sport. Open-wheel street cars, such as the Ariel Atom, are very scarce as they are often impractical for everyday use.
