アルトゥーロ・メルツァリオ
The team did not participate in 1975 24 Hours of Le Mans held on June 14–15, which did not count toward World Championship for Makes due to the conflict between FIA and ACO. Arturo Merzario, paired with Nino Vaccarella, did win the 1975 Targa Florio on July 20 driving an Alfa Romeo 33TT12, but the event no longer counted for the championship and the entry was made by Autodelta directly without involvement by the team.
