Chronology
SuccessorOSCA FS 372

Due to the variety of engines of different displacement sizes and the comparatively large number of chassis built (thanks to strong sales), the OSCA MT4 had an unusually long service life for a competition car. Thus the remarkable success story for the racing car model. Between 1948 and 1966, it managed to rack up 92 wins, 109 class wins, 9 pole positions, and 194 podiums - an impressive record for such a small manufacturer without the means of sustaining a factory competition effort.
