1949 Grand Prix season

The 1949 Grand Prix season was the fourth post-war year for Grand Prix racing and the final year before the beginning of the Formula One World Championship. Races were run to a formula which restricted engines to 1.5 litres supercharged or 4.5 litres naturally aspirated; the formula was called Formula A, but would be renamed to Formula One in 1950. There was no organised championship in 1949, although several of the more prestigious races were recognised as Grandes Epreuves by the Association Internationale des Automobiles Clubs Reconnus (AIACR).
