The Caudron C.714-R was designed in 1938 by Marcel Riffard to challenge the world speed record, then held by German pilot H. Würster in a Bf 109 prototype at 610 km/h (380 mph). Unlike its later sibling, the C.714 Cyclone fighter, the C.714-R was intended solely for racing and performance testing, not for combat. The project was abandoned before completion as attention shifted to military needs, though its design work influenced the later C.710-C.714 fighter prototypes.
