The Maserati A6GCM was a Formula 2 race car built and used by Maserati .In 1952 , a new regulation came into effect in Formula One , the highest Monoposto class: The races for the drivers' championship were extended with vehicles of racing formula 2 .
When two-litre unsupercharged Formula 2 cars became acceptable for Grands Prix when the Formula was changed for 1952—3, Maserati's spearhead was a development of the sports-racing A6G six-cylinder engine first produced in 1947.Gioacchino Colombo re-worked it, and for 1952 it gave 165 bhp from 1988cc.
Maserati often ran Ferrari close the more so in 1953, with handsome new bodies and the driving of Argentinians Juan-Manuel Fangio and José Froilan Gonzalez. Success came finally at Monza, where Fangio won Maserati their first Italian GP victory.
This was an emotional moment, and it was from the A6GCM car—often erroneously referred to as the 'A6SSG' — that the archetypal front-engined Grand Prix car of the nineteen-fifties, the Maserati 250F 2.5-litre six-cylinder, was subsequently developed for competition in 1954 to 1960. The initials 'GCM' indicated 'Ghisa' -iron (cylinder block -which by this time was light alloy) ; 'Corsa' -racing; 'Monoposto' -single-seater.
Since the engines in 1952 were allowed to have a maximum of 500 cc with compressor or 2000 cc without compressor, Maserati renounced compressors. This waiver necessitated the use of three Weber 38DC03 carburettors. The engines got two overhead camshafts .
The chassis was taken over by the 4CL and the wheelbase was shortened to 2280 mm. The low unladen weight was partly due to the bodywork built by Fantuzzi .
Alberto Massimino and Gioacchino Colombo , both from Scuderia Ferrari and Alfa Romeo to Maserati, reworked the car in 1953. However, Colombo did not have much time to do so as he left Maserati in the spring of 1955. The engine was fundamentally improved and now made 25 hp more. The rear axle has been modified and the front brakes have been reinforced. The gauge decreased at the front to 1225 mm and at the rear to 1160 mm.
Sporty the A6GCM was the main enemy, the Ferrari 500 , but clearly inferior. For the first time José Froilán González , also he came from Ferrari to Maserati, which challenge Scuderia at the Grand Prix of Italy . In the end, the Argentine had beaten only Alberto Ascari .
The big hour for Maserati and the A6GCM struck at the Italian Grand Prix a year later. The two factory Maserati Juan Manuel Fangio and Onofre Marimón provided a race-long windshield duel with the factory Ferrari of Ascari and Giuseppe Farina . In the final corner, Parabolica, the last lap, Ascari turned; Fangio and Farina dodged the grass, but Marimón could not dodge and bounced off Ascari. So Fangio celebrated the first victory for Maserati in the World Cup.
Maserati also sold the A6GCM to private investors. So had drivers like Prince Bira , Gino Bianco , Felice Bonetto , Eitel Cantoni , Johnny Claes , Hermann Lang and Luigi Musso success with the agile vehicle.
