When Alfa Romeo was confiscated by the Fascist government of Benito Mussolini in 1939, Enzo Ferrari moved to Modena where he founded Auto Avio Costruzioni. he was prohibited by contract from racing for four years, so his factory was producing machine tools and aircraft accessories.
In its non-competition period Ferrari produced only one model: the Ferrari Auto Avio Costruzioni 815 (or Tipo 815). The car debuted in 1940 at the "Gran Premio Brescia della Mille Miglia".
The two units built by Ferrari were driven by Alberto Ascari and Lotario Rangoni di Machiavelli, but both of them failed to finish the race. After the first lap the two cars are the twelfth and thirteenth, but first in the 1500cc class. However the first one retired after the second lap and the second one after the seventh lap, both of them due to mechanical failures.
