The Maserati 4CM is an open-wheel Grand Prix motor racing car, designed, developed and built by Italian manufacturer Maserati, in 1931. 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 1,100 cc ( L; 67 cu in) Tipo 4CM was Maserati's first racing voiturette. The name of the car is derived as follows: Built alongside the 4CS two-seater sports-racer, the 4CM was powered by a 1, cc ( L; cu in), (65 x 82 mm) twin-overhead-camshaft supercharged four-cylinder engine that produced 125 hp (92 kW) at 6,600rpm, an output sufficient to propel it to a top speed of 210 km/h (130 mph). Some cars came with a spare cylinder block, pistons, connecting rods and supercharger enabling it to be converted to 1, cc ( L; cu in), (69 x 100 mm) when required. Depending on the size of the engine, the roots-type supercharger boosted power to 90–150 hp (66–110 kW). It succeeded the Maserati Tipo 26M, and was itself slowly replaced by the Maserati 6CM around 1936.
