The Renault 80 hp, or Type WS in British service, was a V-8 aero engine that first ran in 1914. The engine was manufactured in Britain by Renault Limited of West Brompton, London between August 1914 and December 1918, seven other companies, including Rolls-Royce and Brazil Straker,^[2] also produced the engine.^[3] The Renault V-8 engines were noted as inefficient but reliable, the inefficiency being mainly due to the excessively rich fuel/air mixture used to assist cooling.^[4]

Applications

Airco DH.6
Alliance P.1
Avro 548
Farman Shorthorn
Vickers F.B.7A
