In view of the disappointing performance of the Caudron C.714, the Air Force issued a request for the engine power to be increased, with the adaptation of a Hispano-Suiza 12 Y-31 propellant of 860 hp, Renault does not able to supply an engine attaining such power, although a sixteen-cylinder reverse V air-cooled engine is under development. The engine initially planned cannot be adapted on the cell, it was ultimately an Isotta-Fraschini Delta RC-40 engine, twelve inverted cylinders with a power of 730 hp that was chosen. The assembly was carried out on a C.715 cell. The fuselage of this model was fully metallic with Duralumin panels, the wing with leading edge beaks remaining wooden construction. The planned armament included six MAC 34 M39 machine guns under the wings. Also, the cell was divided into pre-assembled elements that can be built by non-specialized subcontractors so as to reduce manufacturing time (less than 6,000 hours of work). The C.760 prototype flew for the first time in May 1940. The first tests showed good performance in speed (570 km / h) and in ascending capacity, but development was stopped by the German advance in June 1940.

Among the planes captured on the Guyancourt site, there are several Caudron of various models, including the Caudron-Renault 760 who had made his first tests there in May 1940. The CR.760 was used by the Germans as a decoy in a field near Orleans at Cerqueux, painted with camouflage and black crosses.
