Why it matters

This one-off Touring fastback built a record lead at the 1938 Le Mans 24 Hours before mechanical trouble ended its run. Its enclosed aerodynamic body with integrated wings was unusually advanced for the period, and the car survives in Alfa Romeo's own museum.

History

In early 1938 five 8C 2900B competition chassis were modified, and one received a Touring coupé body by Carlo Felice Anderloni in place of the Mille Miglia spider body. At Le Mans, Raymond Sommer and Clemente Biondetti built an 11-lap lead by Sunday morning, but a tyre failure on the Mulsanne straight and a subsequent mechanical failure forced retirement. The car was later sold in Rome, rediscovered there in the late 1960s, passed through several collectors and was reacquired by Alfa Romeo in the late 1980s in exchange for a 158 'Alfetta'; it is displayed at the Museo Storico.
