For 1970 Swiss racer Silvio Moser commissioned Guglielmo Bellasi to design a Grand Prix car for him. The Swiss-Italian Bellasi company specialized in manufacturing composite parts for racing cars and produced cars for Italian Formula 3 in late 1960s. The Cosworth-powered Bellasi F1 car used some components from the Brabham BT24 chassis which Moser had raced in the 1969 season. The car featured a simple riveted aluminium monocoque with tubular sub-frame carrying the radiator and front suspension. Bellasi was ready for the Dutch Grand Prix in June but failed to qualify in Zandvoort, as well as in two next Moser’s attempts at Clermont-Ferrand and Hockenheimring. The car finally made it onto the grid at the 1970 Austrian Grand Prix, but retired after 13 laps due to radiator failure. Then Moser was DNQ at the Italian Grand Prix. Bellasi reappeared for the non-championship Argentine Grand Prix in 1971, entered by the Jolly Club of Switzerland. In September Moser entered the car again at the 1971 Italian Grand Prix and qualified but retired after only five laps.
