1953 OSCA MT4 Navigation
By 1953 the Maserati brothers had increased the capacity of their engines in order to compete with the new Porsche 550 in the 1500cc and 2-liter classes. Among other improvements, the revised OSCA 2AD engine (OSCA was established by the Maserati brothers) was fitted with a new double-overhead-cam head and twin side-draft DCO Weber carburetors. The new head made all previous OSCA engines almost obsolete, and many were returned to the factory to be modified.
This OSCA MT4 2AD was the first MT4 built with the new 1450cc motor, and it is one of only three OSCA spiders built with an aluminum body by Carrozzeria Frua. It also happens to be one of the most successful OSCAs ever raced in North America. It was first owned by Jim Simpson who, with teammate George Colby, finished fourth overall and second in class behind Stirling Moss in the 1954 Sebring 12 Hours race. Simpson later sold the car to Jim Kimberly, and the MT4 2AD continued to win. In the mid-1990s the car was partially restored.
