The Maserati 200S (Tipo 52) is a racing car made by Italian automobile manufacturer Maserati as a successor to the Maserati A6GCS. 28 cars were made in total. The development of the 200S, codenamed Tipo 52 started in 1952, led by Vittorio Bellentani. The 250S was developed in response to Ferrari's 500 Mondial which featured a four-cylinder engine and was quite successful in sports car racing. The car had a 1994.3 cc inline-four light-alloy engine, featuring dual overhead valves per cylinder and twin camshafts, double Weber 50DCO3 (first few cars only) or 45DCO3 carburetors. The engine was rated at 190 PS at 7,500 rpm. Many chassis components were identical to the Maserati 150S in order to speed up development, except the rigid rear axle inherited from the Maserati A6.
Maserati made the first three chassis internally, but outsourced a tubular chassis to Gilco which was modified by Maserati. The first five aluminium bodies were made by Celestino Fiandri, and the 23 final bodies were made by Medardo Fantuzzi.
The 200S debuted at the 1955 Imola Grand Prix, driven Franco Bordoni, but yielded disappointing results. The 200S was then entered at the 1955 Targa Florio driven by Giovanni Bracco and Bordoni along with a 150S. Both cars were forced to retire, with Maserati winning the race with a A6GCS driven by Francesco Giardini.
