Monsieur Georges Cousy  lived at Castillon la Bataille, 30 miles east of Bordeaux,  France. An ex motorcycle racer, he built two 500 racers in the 1950's. The first car, built in 1952, had a motorcycle engine (probably Norton) and a motorcycle gearbox. Suspension was by transverse leaf spring, front and rear.  This car was entered in the Circuit de Paris at Montlhéry on 21st September 1952.

The second car, built in 1955, used a flat opposed twin two-stroke engine of M. Cousy's design. The crankshaft lay in a fore and aft direction, and drove a gearbox situated behind the rear axle. The rear axle included a differential.  The engine crankcase was fed by a Roots supercharger, which only flowed 496cc of air per engine revolution. Because of this, the engine fell within the Formula 3 regulations of the day.  The chassis rails were tubular and the suspension was cannibalized from the 1952 car. The bodywork was fiberglass.  This car was tested (though not raced) at Montlhery in late 1955.
