Why it matters

A closed streamlined berlinetta on the Fiat 508 S Balilla Sport chassis, made for the Mille Miglia. The added weight of the body was not offset by its aerodynamics, so it was not competitive, and Fiat built only eleven.

02Production & history

Production

Every figure says what it counts.

What is countedFigureBasisStatus

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Fiat decided a closed body might help in the Mille Miglia, which was run in northern Italy in winter. One of the berlinettas finished 14th overall and second in its class in the 1936 Mille Miglia.
