Red Maserati 4CM from 1937. 1.5L. in Monaco car museum
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 (1.1 L; 67 cu in) Tipo 4CM was Maserati’s first racing voiturette.
