Team story
Origins
Bindo, Ettore and Ernesto Maserati founded O.S.C.A. in Bologna in 1947, after leaving the company bearing their surname. The new name genuinely identified a different business. Its first cars were small sports cars; the single-seater project broadened that activity without replacing it.
The 4500G entered the World Championship at Monza in 1951 with Franco Rol, who was classified ninth.
The Formula 1 journey
In 1952 and 1953, when the championship adopted Formula 2 rules, two-litre single-seaters appeared with drivers such as Élie Bayol and Louis Chiron. The presence remained sporadic and produced no points. The final entries in 1958 brought no further starts: the World Championship racing career ended before the last year in which the name appears in the entry lists.
Historical timeline
Three chapters in the story of O.S.C.A.
Three episodes to revisit the people, cars and races that shaped this journey.
First appearance · Italian Grand Prix
Franco Rol · Italian Grand Prix 1951. The recorded position is P9; this number alone does not show whether the driver completed the race distance. This is the first recorded race start, or the first entry if the team never started a race.
Sporting landmark · Italian Grand Prix
Franco Rol · Italian Grand Prix 1951. The recorded position is P9; this number alone does not show whether the driver completed the race distance. This marks the first win or podium where one exists, otherwise the highest recorded placing for this constructor.
Latest recorded appearance · Italian Grand Prix
Élie Bayol · Italian Grand Prix 1953. The recorded outcome is DNF. This is the last race start attributed to this constructor in the archive, not necessarily the end of the organisation behind it.
A distinctive way of racing
The designations 4500G, 20 and F2 represent different programmes. O.S.C.A. mainly built cars for customers and sports-car racing, where a small engine capacity could bring advantages in weight and handling. The MT4 was central to that identity, far more than the prospect of running two single-seaters throughout an entire World Championship season.
What remains
The outright victory at Sebring in 1954, with Stirling Moss and Bill Lloyd for Briggs Cunningham, belongs to O.S.C.A.’s sports-car history, not its Formula 1 record. Setting the two programmes alongside one another shows the Maserati brothers’ approach: cars built for specific tasks and also entrusted to high-level customers. The brevity of the World Championship appearances alone does not measure the company’s significance in racing.
