Maserati Tipo 4CTR/4CS 1100

The Maserati 4CTR/4CS 1100 is a two-seat racing car that Maserati built from 1931 to 1936, and its racing debut was at the Mille Miglia on 12 April 1931. A new series of competitions for small cars had replaced the cyclecar class, so Alfieri Maserati designed a light, nimble model with an easily maintained four-cylinder engine. The first engine version was called 4CTR, for quattro cilindri testata riportata, meaning that the cylinder head could be removed. The prototype won its class and finished twentieth overall in the 1932 Mille Miglia, and that year two variants appeared, the single-seat 4CM and the two-seat sports 4CS. In 1934 Piero Taruffi came fifth overall. The supercharged four-cylinder in-line engine of 1,088.4 cc had twin overhead camshafts and gave 90 to 115 CV, and the car reached 150 km/h, using 25 litres of petrol per 100 km.
