The Maserati 250F was raced in ‘2.5 litre’ Formula One between 1954 and 1960. Twenty-six cars were made. The 250F mainly used the SSG 220 bhp 2.5-litre Maserati A6 straight-six engine; ribbed 13.4″ drum brakes; wishbone independent front suspension and a De Dion tube axle. 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 World Championship driving with Maserati and Mercedes-Benz; Stirling Moss raced his 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. In 1956 Moss won the Monaco and Italian Grands Prix in a works car. In 1957 Fangio drove to four more championship victories, including his legendary final win at the German Grand Prix at the Nürburgring on August 4, 1957, where he overcame a 48 second deficit in 22 laps, passing the race leader, Mike Hawthorn, on the final lap to win. In doing so he broke the lap record 10 times. By 1958 the 250F had been outclassed by the new rear engined F1 cars. The 250F competed in 46 Formula One championship races with 277 entries, leading to eight wins. Stirling Moss later said the 250F was the best front-engined F1 car he ever drove.
