The Maserati 250F is a single-seat Grand Prix racing car produced from 1954 to 1960, built to compete in the Formula 1 World Championship under the 2.5-liter naturally aspirated regulations of the era. Powered by a straight-six engine displacing 2,493cc, the car became one of the most celebrated front-engined Grand Prix machines of the 1950s, earning Juan Manuel Fangio his 1957 World Drivers' Championship in what is widely regarded as one of the greatest drives in motorsport history, the German Grand Prix at the Nurburgring. The 250F was raced both by the factory Maserati team and by a significant number of privateer entrants, making it among the most widely campaigned single-seaters of its period. A lightweight version with a revised tubular spaceframe was developed during the car's production life, and a V12-engined experimental variant was also constructed, though neither displaced the straight-six as the definitive competition configuration.
