Jean Chanabe did not fall back on an existing chassis during the construction, but designed everything himself. In some cases he received support from Mr. Gadras.
However, the original idea of using a Renault engine was discarded. Due to the close relationship with his father's company – father, Charles Chanabe – was a Porsche and De Tomaso dealer in Toulouse, a Porsche engine was ultimately used. In addition, all other parts such as brakes, gears etc. were taken over by Porsche. The existing frame allows an engine output of up to 350 hp.
The construction time for the vehicle was 2 ½ years 1971-1973.
The first test drives took place in August 1973 on the F1 racetrack in Albi, southern France.
Porsche itself soon became aware of this vehicle and after a detailed assessment, Chanabe was allowed by the factory to use the name Porsche for his car
The vehicle was used in mountain and circuit races in France from 1974 to 1990 by different owners.
Ultimately, the prototype was in the possession of the circuit operator of Spa Francorchamps.
