|Maserati A6GCM wins at Monza 1953|
The Maserati A6GCM is a single seater racing car from the Italian manufacturer Maserati. Only 12 cars were built between 1951 and 1953.
The A6GCM belongs to the A6 family of Maserati vehicles which comprised many models from street cars to racing cars. The name of the car is derived as follows:
A6 : the name of the series : A for Alfieri (Maserati), 6 for 6 cylinders
G : Ghisa, the engine block was in cast iron
C : Corsa, for Racing
M : Monoposto, for single seater.
The Tipo6 CS (Corsa Sportivo: barchetta) has been spotted as a good contender even in front of single seaters in Formula 2, despite its small engine. Thus Maserati decided to develop a specific model that would meet the new FIA racing rules.
- Initially with a 1987 cc capacity (long stroke, 72.6x80 mm, with a compression ratio of 13.5 :1) delivering 160hp, in 1951 and 1952
- Then with a 1989 cc capacity (short stroke 75x75 mm, with a compression ratio of 13.5 :1, with twin ignition) delivering 180hp, in late 1952
- And finally with a 1960 cc capacity (shorter stroke 76.2x72 mm, with a compression ratio of 12 :1, with twin ignition) delivering 197hp, in 1953.
The engine was associated to a 4 speed gearbox.
The frame was developed by Medardo Fantuzzi. The car was built in aluminum. The car weighed between 550kg and 570kg depending of the engine used. It used, at the rear a rigid rear axle with cantilevered leaf springs combined with « Houdaille » shock absorbers, in front coil springs are used also combined with « Houdaille » shock absorbers. The brakes are hydraulic driven drums. The initial wheel base was 2280mm to be extended to 2310mm in the later version. The front track was initially 1278mm and was reduced to 1200mm as the car received larger wheels in its later version. The rear track received the same treatment going from 1225mm to 1160mm. The spoked wheels were initially of 4X15 to be replaced by 5X16 in 1953.
The 1953 version was the work of Gioacchino Colombo who modified the car significantly: now with a nearly 200hp engine, new suspension and improved brakes. The body was also reworked and made narrower and the car received an oval front grill. This version is known as the "interim" A6GCM or A6SSG.
The A6GCM foreshadowed the next model: the mythical 250F. In fact several of the later A6GCMs, produced in late 1952 and 1953, were converted to 250Fs in 1954.
With 151 race starts and 81 race finishes, with 23 podiums and 6 Grand-Prix race wins, the A6GCM has had an exceptional track record supported by exceptional drivers.
Note: when Maserati competed in its home town, Modena, it managed to finish in the top three positions.
