The "1600 GT" and "1600 GT2" chassis derived from the racing cars, transformed into elegant 2-seater coupés and spiders by the coachbuilders Frua, Michelotti, Zagato, Fissore and Vignale.
The ambition to participate in the sports world championship and in the Mille Miglia led to the birth of the MT4 equipped with a 2-litre engine, DOHC with desmodromic timing, delivering 165 HP.
This car, driven by Stirling Moss, added victory in the prestigious 12 Hours of Sebring to the OSCA palmarès.
The Osca twin-cam engines, first 1491 cm³ and then 1568 cm³, went on to equip, in a depowered version at 90 HP SAE (80 HP din) and 100 HP SAE (90 HP DIN), more widespread models, such as the Fiat 1500 S (1959-1963) and 1600 S (1963-1966). The Maserati brothers, now elderly, sold the majority shareholding to the Agusta counts, already owners of the motorcycle and helicopter companies of the same name, at the end of 1964.
At the end of 1966 most of the staff in Bologna was fired and it was decided to transfer the company to Gallarate, but already in 1967 OSCA closed its doors.
