Maserati A6GCM

The Maserati A6GCM is a single-seater racing car developed by Maserati for Formula Two, with twelve cars built between 1951 and 1953. Its name encodes its makeup: A for Alfieri, 6 for six cylinders, G for ghisa because the engine block was cast iron, C for corsa meaning racing, and M for monoposto, a single seater. Alberto Massimino and Vittorio Bellentani developed its inline six-cylinder two-litre engine, with twin overhead camshafts and three twin-choke Weber carburettors, which gave between 160 and 197 hp as capacity and compression changed through 1951, 1952 and 1953. The aluminium-bodied car weighed 550 to 570 kg. The 1953 version, reworked by Gioacchino Colombo, is known as the interim A6GCM or A6SSG, and the model foreshadowed the 250F: several later cars were converted to 250Fs in 1954. It made 151 race starts and won six Grand Prix.
