created by Michel Boué, who died in his late 30s shortly before the car went on sale.
The design drawing shown above bears little resemblance to the production model. It was made in April 1967, when Boué was apparently thinking in terms of a fastback body style, and had not yet got past the idea of metal bumpers.
The overall dimensions seem familiar, though, and it’s clear Boué had already decided the 5 should have rectangular headlights.
