The Renault 80 hp, or 8Ca, or Type WS is a development of the Renault 70 hp V-8 aero engine that was produced exclusively in the United Kingdom by Renault's British subsidiary, and its licensees, from 1913 to 1918.

Apart from being physically larger, the only major design change between the 80 hp and the earlier 70 hp model was the use of articulated connecting rods. As a result, corresponding cylinders in each row were arranged directly opposite.
