Brief History:
By the end of 1953 the domination of the A6GCS met with a response from Ferrari with the 500 Mondial.  In 1955 with the A6GCS dating, the 200S engine was installed on a frame developed for a version of the 150S which had borrowed the rigid axle and rear suspension from the A6GCS. The 200S and 150S had been developed in tandem,   The engine copied the style of the 150S and was built in light alloy, five main bearings, dual overhead camshafts with rockers, double ignition two magnetos (replaced later by distributors) and at first with two Weber 50DCO3 and almost immediately by 45DCO3.  Bodies were initially built as with the 150S by Fiandri (the first 5 cars), and the frames in the factory for the first three cars which were also equipped with rigid axles. Subsequently all cars were made with the trellis work and tubes by Gilco and modified slightly in the factory. Similarly to the 150S there was much concentration on aerodynamics and from the sixth car onward bodies were built by Fantuzzi.  With the need to conform to the International sports car rules, the definitive version of what had been prior to the beginning of 1957 the 200S, became from this point the 200SI.  The 200SI went on to win the European hill climb championship in 1957.
