- 1933 Villa Olmo
- Mileage n/a
In 1933 a split whose causes are unknown caused the Villa d’Este company to withdraw from the organization of the event, responsibility for which was wholly assumed by the Automobile Club of Como. Having obtained the support of Princess Maria José, the event was renamed the “Coppa d’Oro Principessa di Piemonte” and was held entirely at Villa Olmo, including the prize giving ceremony, albeit without the referendum, which was discontinued.
