Maserati started the development of the 200S in order to be competitive with Ferrari in Grand Prix racing. Twenty-eight Maserati 200S racing cars were made to replace the aging Maserati A6 GCS racing variants. Some sources say 32 cars were made.
The development program for the car was code named "Tipo 52" and started in 1952. The car was initially powered by a 1994.3 cc inline-four cylinder light-alloy engine, with dual OHV per cylinder and DOHC camshafts, and double Weber 50DCO3 (for the first few cars only) or double 45DCO3 carburetors. Its output was 190 PS (140 kW; 187 hp) at 7500 rpm. Many chassis components were identical to the Maserati 150S, which was co-developed at the same time, except for the rigid rear axle used in the 200S which was inherited from the Maserati A6.
Maserati made the first three chassis internally, but later outsourced a tubular chassis to Gilco. The first five aluminum bodies were, as for the Maserati 150S, made by Celestino Fiandri, and the 23 final ones made by Medardo Fantuzzi.

No wins were seen in its first year of racing in 1955, driven by Franco Bordoni at the 1955 San Marino Grand Prix, followed by drivers Giovanni Bracco and Bordoni at the 1955 Targa Florio. Driver Benoit Nicolas Musy died in a 200S at 'Autodrome de Montlhery, in France in 1956.
In 1957 the name of the car was changed to the Maserati 200SI, Sport Internazionale, to signify its conformance to international sports car racing rules. In 1958 the engine was enlarged to 2.5 liters and the car was named as 250S.
The car scored a resounding victory with Stirling Moss at the wheel during the 1956 Trofeo Supercortemaggiore. He beat four Ferrari 500TRs and described the car as "very quick on twisty circuits" and said it "handled really nicely".
