FIA Formula One continued its policy, established in 1952, of running World Championship races exclusively for Formula Two cars. The governing body sought to expand the championship's geographic reach beyond Europe, and the Argentine Automobile Club secured a round of the championship for the first time.
The 1953 Formula One season comprised nine World Championship rounds, with Alberto Ascari successfully defending his 1952 drivers' title driving for Scuderia Ferrari. The season marked the first championship event held outside Europe (excluding Indianapolis), with the Argentine Grand Prix, though that race was marred by a crash involving Nino Farina that killed nine spectators in an unprotected crowd.
Ascari's back-to-back titles established him as the dominant driver of the early championship era and remained the last World Championship won by an Italian driver as of 2025. The fatal accident at the Argentine Grand Prix highlighted the dangers of inadequate crowd protection at motor racing events, foreshadowing later safety reforms in the sport.
