This is the first open "Cousy" sportscar manufactured by a company called CECE-Ratier, it was fitted initially with a mid-mounted two-stroke 500CC engine (28bhp), flat twin and 4 speed gearbox. The car was similar in mechanical design to the single seaters, and even included a central driving position, but had a light tubular frame. However it retained similar suspension and steering systems to those seen on the F3 cars. Cousy wasn’t alone in using a central driver; such layouts could be seen in Monopole in particular, amongst a number of other small French sports cars.
The body was again made of fibreglass using a light twin layup process, this time with French Stratyl polyester resin which resulted in a very light 26kg finished product. It was designed with low-drag in mind. The completed car weighed only 360kg, kerb, with fuel etc on board.
