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.

Mechanical details

The 250F principally used the SSG 220 bhp (@ 7400 rpm) 2.5-litre Maserati A6 straight-six, 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.[1]

Racing history

The Maserati team's 250Fs before the start of the 1957 British Grand Prix.
The Maserati 250F is sufficiently important in the history of motorsport that replicas have been built for display and racing.

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.

Although Bellentoni and Massimino left for Ferrari and Moss left for Mercedes-Benz, 1955 saw a setup with 5-speed gearbox as well as SU fuel injection (240 bhp) and Dunlop disc brakes. Jean Behra ran this in a five-member works team which included Luigi Musso.

In 1956 Stirling Moss won at the Italian Grand Prix and the Monaco Grand Prix in his private car.

In 1956 three 250F T2 cars first appeared for the works drivers. Developed by Giulio Alfieri using lighter steel tubes they sported a slimmer, stiffer body and sometimes the new 315 bhp (235 kW) V12 engine, although it offered little or no real advantage over the older straight 6. It was eventually reused in the unsuccessful 1966 F1 Cooper Maserati.

In 1957 Juan Manuel Fangio drove to four more championship victories, including his legendary final win at German Grand Prix at the Nürburgring (Aug. 4, 1957), where he overcame a 48 second deficit in just 22 laps, passing the race leader, Mike Hawthorn, on the final lap to take the win. In doing so he broke the lap record at the Nürburgring, 10 times.

The Constructors' World Championship was introduced in 1958, by which time the 250F was generally outclassed. However, the car remained a favourite with the privateers, including Maria Teresa de Filippis and was used until 1960.

In total, the 250F competed in 46 Formula One championship races with 277 entries, leading to eight wins. Success was not limited to World Championship events with 250F drivers winning many non-championship races around the world.
