The Maserati 250F was a racing car made by Maserati of Italy used in '2.5 litre' Formula One racing between January 1954 and November 1960. Twenty-six examples were made.
The 250F principally used the SSG 220 bhp (@ 7400 rpm) 2.5-litre Maserati A6 straight-six engine, ribbed 13.4" drum brakes, wishbone independent front suspension and a De Dion tube axle. It was built by Gioacchino Colombo, Vittorio Bellentani and Alberto Massimino; the tubular work was by Valerio Colotti.
A streamlined version with bodywork which partially enclosed the wheels (similar to the 1954 Mercedes-Benz W196 "Typ Monza") was used in the 1956 French Grand Prix.
The 250F first raced in the 1954 Argentine Grand Prix where Juan Manuel Fangio won the first of his two victories before he left for the new Mercedes-Benz team. Fangio won the 1954 Drivers' World Championship, with points gained with both Maserati and Mercedes-Benz; Stirling Moss raced his own privately owned 250F for the full 1954 season.
In 1955 a 5-speed gearbox; SU fuel injection (240 bhp) and Dunlop disc brakes were introduced. Jean Behra drove this in a five-member works team which included Luigi Musso.
In 1956 Stirling Moss won the Monaco and Italian Grands Prix, both in a works car.
