Why it matters

The sporting two-seat version of the Balilla, with a finned tail that housed the spare wheel. It was offered as the Coppa d'Oro (cycle fenders, lighter chassis) and the Mille Miglia type, and it ran in the Mille Miglia and other Italian events.

02Production & history

Production

Every figure says what it counts.

No production figures recorded yet.

History

The body was originally styled by Ghia; Fiat bought the design and modified it. The first series Coppa d'Oro and Mille Miglia cars were followed in 1934 by a second series with a four-speed gearbox and an overhead-valve engine of about 46 bhp, which gave the model the name 508 S.

A Coppa d'Oro with a period Siata-modified engine produced 43 hp against 36 hp for the standard car and sold at Gooding's 2011 Scottsdale sale for 121,000 USD.
