The first, 1950, car used a front mounted modified Simca engine in which he finished third in the Coupe D'Or at Montlhéry 1951.
The second car, for 1952 was more of a Cooper design with a mid mounted JAP engine, purchased from Philippe Schell, and Fiat style wishbones and transverse leaf springs. Roger finished fourth at Montlhéry in April but was never happy with the chassis.
At Draguignan in May 1952
