Motor vehicle transformable into a pickup

The vehicle has a boot (3) defined by a partition of separation between an interior space and the boot. An assembly (11) formed by a cover (12) and a rear end (13) is supported by a frame (20) displaced between upper and lower positions by a hinge. The cover and rear end close the boot in the upper position, and the cover is pressed against a floor to transform the vehicle into an open dump type vehicle in the lower position.
