The Fiat A.74 was an Italian-made, air-cooled radial engine featuring two rows and fourteen cylinders, developed during the 1930s to serve as a propulsion system for aircraft. It powered several of Italy's key military planes throughout World War II.
Design and development
Fiat's introduction of the A.74 represented a shift from their earlier liquid-cooled inline engines toward larger air-cooled radial configurations. Although Fiat had previously manufactured smaller radial engines, the A.74 significantly increased both power output and physical dimensions. This engine family was produced extensively and led to the creation of related models such as the A.76, A.80, and A.82, with each subsequent version offering greater size and enhanced performance. Over time, this series expanded from 14-cylinder layouts to 18 cylinders, with power ratings rising from 870 hp up to 1,400 hp.
