The 1924 Grand Prix season saw Grand Prix motor racing spread further across Europe and North America. In Italy a number of new open-road events were held. In France two new circuits were opened – at Montlhéry near Paris and Miramas near Marseille. After Fiat's dominance the previous year with its supercharged Type 805, most teams adopted supercharging with their new cars. Significantly the French teams of Bugatti, Delage and Rolland Pilain chose not to.
