Maserati A6GCM

The Maserati A6GCM is a single seater racing car from the Italian manufacturer Maserati. Only 12 cars were built between 1951 and 1953.

Introduction

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.

Design

The inline 6-cylinder two-liter engine with DOHC and 12 valves, 3 two-barrel (twin choke) Weber carburetors delivered Script error: No such module "convert". to Script error: No such module "convert".. It was developed by Alberto Massimino and Vittorio Bellentani.

  • Initially with a Script error: No such module "convert". capacity (Script error: No such module "convert"., with a compression ratio of 13.5 :1) delivering Script error: No such module "convert"., in 1951 and 1952
  • Then Script error: No such module "convert". capacity (Script error: No such module "convert"., with a compression ratio of 13.5 :1, with twin ignition[clarification needed]) delivering Script error: No such module "convert"., in late 1952
  • And finally with a Script error: No such module "convert". capacity Script error: No such module "convert"., with a compression ratio of 12 :1, with twin ignition[clarification needed]) delivering Script error: No such module "convert"., in 1953.

The engine was mated to a 4-speed gearbox.

The frame was developed by Medardo Fantuzzi. The car was bodied in aluminum and weighed Script error: No such module "convert"., depending of the engine installed. The rigid rear axle employed 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 wheelbase was Script error: No such module "convert".; this was extended to Script error: No such module "convert". in the later version. The front track was initially Script error: No such module "convert". and was reduced to Script error: No such module "convert". as the car received larger wheels in its later version.[citation needed] The rear track received the same treatment going from Script error: No such module "convert". to Script error: No such module "convert".. The spoked wheels were initially Script error: No such module "convert"., replaced by 5X16 Script error: No such module "convert"., in 1953.

Evolution

The 1953 version was the work of Gioacchino Colombo who modified the car significantly: now with a nearly Script error: No such module "convert". 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 250F. In fact several of the later A6GCMs, produced in late 1952 and 1953, were converted to 250Fs in 1954.

Results

The same model raced in Formula One races and in Formula Two, in races which counted for the World Championship as well as in non-championship events, as it was often the case in the early 1950s.

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, in 1953, it managed to finish in the top three positions.
