Maserati 250F was first raced in January 1954, in the '2.5 litre' Formula One racing (thus, the '250' and 'F'). 26 examples were made in total. It mainly used the Maserati A6 SSG straight-six 2.5-litre engine (220 bhp at 7400 rpm), ribbed 13.4" drum brakes, wishbone independent front suspension and a De Dion tube axle.
