History

Chassis 2111006 was the sixth first-series 8C built, in 1931, on the short chassis with a minimal works-style body for Alfa Corse. It was not ready for the 1931 Targa Florio, and its first known race was the 1931 Belgian Grand Prix, where Minoia's podium finish helped secure the first European Drivers' Championship. Scuderia Ferrari acquired it on 29 July 1931 and ran it for Nuvolari at the Coppa Ciano days later.

In 1932 it received Monza-specification upgrades and fuller Zagato-style rear bodywork, and appeared in a Scuderia Ferrari team photograph on the way to the 1932 Mille Miglia. It also started the 1934 Mille Miglia but retired shortly after Rome.

Identification guide

How to tell an original from a replica or later conversion.

The cached Gooding lot is a 1932 long-chassis spider, chassis and engine number 2211086, delivered new to Naples with one-off open Zagato coachwork. Gooding lists the body as "in the style of Zagato" and says it has been recreated by Dino Cognolato, so a Zagato-style spider on a genuine 8C chassis may carry a recreated rather than original body; the provenance of the coachwork should be checked.
