The OSCA Sports Racing MT-4 was powered by a four-cylinder, dual overhead cam engine that displaced 1.5-liters and offered 130 horsepower. OSCA (which translates to Officine Specializzate Costruzione Automoibli) were built in Bologna, Italy by the Maserati brothers from 1947, when they departed from the company that bore their name, until 1967, shortly following their retirement.
The cost for the 1.5-liter MT-4 sold for around $10,000, a considering sum at the time.
At the 12 Hours of Sebring in 1954, this OSCA was a giant killer. 60 cars started the race and only 25 finished the race. This was one of six OSCA's on hand and Briggs Cunningham entered it for drivers Stirling Moss and Bill Lloyd. Not only did it win the race outright in a stunning upset - five laps ahead of the 2nd place car - but also two other OSCAs finished 4th and 5th to win the Index of Performance for the marque.
