O.S.C.A.

O.S.C.A. Fratelli Maserati S.p.A. (Officine Specializzate Costruzioni Automobili Fratelli Maserati S.p.A.) was an Italian manufacturer of racing and sports cars established in 1947 in San Lazzaro di Savena, outside Bologna. It was founded by Ernesto, Ettore, and Bindo Maserati, three of the brothers who had founded Maserati in 1914. They left Maserati in 1937 after selling their shares to Adolfo Orsi.

O.S.C.A. focused primarily on small-capacity, high-performance vehicles, often using Fiat components. The company achieved considerable success in motorsport, particularly in the 1100 cc class, winning the 1954 World Sportscar Championship. Their cars were known for their advanced engineering and innovative designs.

The Maserati brothers aimed to build racing cars that were competitive but less expensive than those produced by their former company. This approach led to a focus on smaller engines and lightweight construction. O.S.C.A. models were frequently driven by both amateur and professional drivers in a variety of racing events.

In 1963, O.S.C.A. was acquired by Count Domenico Agusta, the owner of MV Agusta. Production continued for a few more years, but eventually ceased in 1967 as MV Agusta shifted its focus. Despite its relatively short lifespan, O.S.C.A. is remembered for its significant contributions to Italian motorsport and its innovative engineering approach.
