But then Chiribiri was licensed to build 100 aeronautical motors for French engine manufacturer Gnome et Rhone, so aircraft production ceased.

This success enabled Chiribiri to open a ‘flying school’ at the factory, training pilots who subsequently flew in World War I.

The car had been built in 1913, and had a 8,000 cc inline-four Chiribiri aircraft engine producing 130 CV (96 kW) installed into a Fiat 50-60 HP chassis.

Gustavo Brunetta d'Usseaux, a rich land owner, commissioned the construction of 100 examples of the ‘Siva’, a 980 cc economy car, but the financial side failed so Chiribri carried on alone.

This was an open-bodied four-seater with a 1593 cc, side-valve, 19 CV (14 kW), and an embryonic transaxle layout with the four-speed transmission mounted with the rear differential.

In 1921 Amedeo Chiribiri, racing under the pseudonym of Deo, won the 'Coppa della Cascine' in Florence and Mauro Ramassotto came second in the 2,000 cc class of the Rome Criterium.

So, despite the 1927 venture into diesel and industrial engines, when financial depression hit Europe the company closed on 3 September 1929, its assets being sold to Lancia.

Amedeo, his son born in 1898, and Ada his daughter, had been his closest collaborators and team members, having won races, hill climbs and rallies.
