The Maserati 4CM is an open-wheel Grand Prix motor racing car, designed, developed and built by Italian manufacturer Maserati, in 1931.[2][3]
In 1930, Maserati decided to concentrate its efforts on the voiturette class, which was not contested by German manufacturers such as Mercedes-Benz and Auto Union. The 1100 cc Tipo 4CM was Maserati's first racing voiturette.[4] The name of the car is derived as follows: 4: 4-cylinder engine; C: Corsa, for racing; M: Monoposto, for single seater. Built alongside the 4CS two-seater sports-racer, the 4CM was powered by a 1088.4 cc, (65 x 82 mm) twin-overhead-camshaft supercharged four-cylinder engine that produced 125 hp-metric at 6,600rpm, an output sufficient to propel it to a top speed of 210 km/h. Some cars came with a spare cylinder block, pistons, connecting rods and supercharger enabling it to be converted to 1495.7 cc, (69 x 100 mm) when required. Depending on the size of the engine, the roots-type supercharger boosted power to 90-150 hp-metric.[5][6]
It succeeded the Maserati Tipo 26M, and was itself slowly replaced by the Maserati 6CM around 1936.[7][8]
