"Alf
In 1949 a gentleman fond of motoring, the Turin-known industrialist and engineer Sandro Fiorio, in agreement with his friend Piero Avalle, is put in a special small car built to race in the class up to 750 cc.
The chassis (tubular) is made by the workshop of the brothers Grignani, while the engine - apparently obtained directly from Lancia thanks to the friendships of the engineer - Ardea is reduced to little more than 700 cc displacement. This tiny little car, called "Alf" (acronym for Avalle Fiorio Lancia) is brought to the race a bit 'by one and a bit' on the other of the two friends (the Mille Miglia in 1950 and 1951, the two will race in pairs).
