"Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing defined by the F\u00E9d\u00E9ration Internationale de l'Automobile (FIA), motorsport's world governing body. The \"formula\" in the name refers to a set of rules to which all participants and cars must conform. 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."@en . . .
