The Renault 90 hp, or 12A, was the world’s first V12 aircraft engine. The engine was developed in 1911 from Renault’s earlier V8 engines and used the same air-cooled design.
The engine was first exhibited in December 1911 at the Paris Air Show and powered several aircraft during the 1912 competition season. Renault followed up the 90 hp model with a, similarly designed, 100 hp model during the summer of 1912.
