Formula One is the highest class of single-seater auto racing sanctioned by the Fédération Internationale de l’Automobile and owned by the Formula One Group. The World Drivers’ Championship, which became the FIA Formula One World Championship in 1981, has been one of the premier forms of racing around the world since its inaugural season in 1950.
The 1946 Grand Prix season was the first post-war year for Grand Prix motor racing. It was notable for including the first ever race run to Formula One criteria, the 1946 Turin Grand Prix at the Parco del Valentino. There was no organized championship in 1946, although Raymond Sommer proved to be the most successful driver, winning five Grand Prix.
