Maserati 250S

The Maserati 250S, with its derivative the 250 Sport, is a sports racing car that Maserati developed and built between 1954 and 1957, and only two models were produced. It was an attempt to improve on the 200S by enlarging its inline four-cylinder engine to 2.5 litres, a change that delivered only about 6 hp more than the two-litre unit. The first version, a single car from 1954, put the 2,494 cc six-cylinder engine of the 250F Formula One car into an A6GCS chassis. The second version of 1957 used the 200SI mechanics with the larger four-cylinder engine, and four examples were built, four 200SI chassis becoming 250S cars this way. Factory cars started the 1957 Sebring 12 Hours, and in 1958 Jim Hall took his first sports car race victory in a 250S at Eagle Mountain.
