Ten years earlier, in 1937, the remaining Maserati brothers had sold their shares in the company to the Orsi family, who, in 1940, had relocated the company headquarters to their hometown of Modena, where it remains to this day. The new workshop for O.S.C.A. was... established at San Lazzaro di Saveno outside Bologna, where Maserati was originally made 1926 to 1940. Their basic business goal was to develop an automobile to compete in the 1100 cc racing class. O.S.C.A.'s first automobile was the MT4, for Maserati Tipo 4 cilindri. The 1092 cc engine at 6000 rpm had a FIAT-derived block, alloy top, and the coach was built as a two-seater barchetta.
