Arturo Merzario
Marlboro continued to back Frank Williams and his Iso-Marlboro-Ford FW for former Ferrari driver, Arturo Merzario. While Hesketh Racing were building their own car back in England, they entered James Hunt in a year-old March, while Graham Hill had Lola Cars build two cars for himself and Guy Edwards. Rikky von Opel completed the field, once again driving for Team Ensign.
