The naked chassis and a finished car, and some no doubt informative text that I can't understand:
Here's my translation. Not the best as I'm not fluent in French, but I hope it's ok.
"When the engine is out of Renault 4CV, we notice the surprising similarity of its construction to the one of Citroen 11CV. From this there is only one step to the thought that by putting the Renault 4CV engine in front, you could get the driving qualities of a Citroen. Mr. Pascal from Rouen has made this step.
First he made the chassis, on which he mounted the Renault engine block. The wheels and transmission are taken from Panhard Dyna. The front suspension is transverse springs, the rear is longitudinal springs coupled with small coil springs, which provide the grip for 4 wheels, shock absorbers g.r. [I don't know what 'g. r.' means]
With such an assembly, one can fear the weight of the car. Indeed, weighing over 600 kilos, it is heavier than the original car. The body of the Rouen hybrid and its low ground clearance are surpsrising. When tested, the car ,its engine equipped with many improvements, reached 180 kph.
