OSCA (Officine Specializzate Costruzione Automobili—Fratelli Maserati S.p.A.) was founded in 1947 by Ernesto Maserati (engineering manager) and his two brothers Ettore, and Bindo (operations managers) who had all left Maserati after their ten-year contract with Adolfo Orsi terminated. The first car the brothers and their new company would produce would be the MT4 (Maserati Tipo 4 cilindri). The 1100 cc MT4 first raced in 1948 at the Pescara Circuit and the Grand Prix of Naples, where it was driven to a win by Luigi Villoresi. Most of the cars OSCA would produce would be sportscars that would take part in such races as the Mille Miglia and other endurance events. But then, going into the 1952 season, the brothers would be lured back into Grand Prix racing. Then, towards the end of 1951, the Maserati brothers designed a car for Grand Prix racing. It was the OSCA 20. The company had already made its presence known in the World Championship with its OSCA 4500 Tipo G back in 1951. The design for the ’20’ would start with the 4500 Tipo G. The car would use a longitudinal 6-cylinder engine instead of the V12 used to power the 4500. The smaller engine; therefore, enabled to design a car with a lower-profile nose although it would still spot a large oval-shaped grille covering the radiator and oil cooler. Elie Bayol had driven one ‘20’ during the end of the 1952 season and had some success with it. In 1953 Louis Chiron, famous pre-war Grand Prix driver,born in 1899 in Monte Carlo, now 53 year old, would decide to re-enter the World Championship driving under his own name. He has bought one of the new OSCA cars to race in Grand Prix. Chiron drove new OSCA to 2nd place in Syracuse Grand Prix in March, started in several more non-championship races and finally appeared in French Grand Prix when he was classified 15th. Then Chiron was DNS at Silverstone and Bremgarten. Final appearance of Chiron’s OSCA in Grandes Epreuves was seen in the Italian Grand Prix where Louis finished 10th, 8 laps behind the winner. Two weeks later Chiron raced in Modena Grand Prix, but again was not classified with 10 laps lag. After the 1953 season, the new Formula One regulations would be imposed, which made the OSCA 20 chassis non-compliant. In addition, the rather poor results would lead the Maserati brothers to switch their focus. From 1954 onwards, OSCA would focus, almost exclusively, on sportscar racing.
