Formula One, also known as F1, and currently officially referred to as the FIA One World Championship, is the highest class of auto racing sanctioned by the Fédération Internationale de l'Automobile (FIA). in the name refers to a set of rules to which all participants and cars must comply. The F1 season consists of a series of races, known as Grands Prix, held on purpose-built circuits, and to a lesser extent, former public roads and closed city streets. The results of each race are combined to determine two annual World Championships, one for the drivers and one for the constructors, with racing drivers, constructor teams, track officials, organizers and circuits required to be holders of valid Super Licences, the highest class racing licence issued by the FIA.
F1 cars race at high speeds, up to 360 km/h (220 mph) with engines revving up to a formula imposed limit of 18,000 RPM. The cars are capable of pulling in excess of 5 g-forces in some curves. The performance of the cars is highly dependent on electronics (although traction control and driving aids have been banned since 1991), aerodynamics, suspension and on tyres. The f1 has seen many evolutions and changes through the history of the sport.
