Maserati 4CS Brianza Roadster I gallery (1932–1936)
The Maserati 4CS 1500 was a legendary pre-war two-seater sports car created for circuit racing and endurance competitions.
The Maserati 4CS 1500 (Corsa Sport) was a purpose-built two-seater open sports racing car developed by the Maserati brothers in the early 1930s for national and international sports car categories, most notably the Mille Miglia. Built on a lightweight steel ladder-frame chassis with tubular crossmembers, the vehicle featured handmade aluminum bodywork styled as an open two-seat roadster/spider crafted by renowned Italian coachbuilders. Power was provided by a 1.5-liter (1496 cc) inline-four engine featuring a cast-iron block, an aluminum cylinder head with double overhead camshafts (DOHC), dry-sump lubrication, and a Roots-type mechanical supercharger, producing between 90 and 115 hp depending on fuel blend and boost levels. It was mated to a robust 4-speed unsynchronized manual transmission delivering drive to a rigid live rear axle. Suspension consisted of live axles front and rear supported by semi-elliptic leaf springs and friction dampers, controlled by large mechanical drum brakes on all wheels. Produced in very small numbers, the 4CS 1500 achieved considerable racing success across Europe.
