A motor-vehicle floor panel structure comprises a front body sub-unit (2), a central floor sub-unit (3), and a rear body sub-unit (4). The central floor sub-unit (3) comprises a front floor structure (301) including a central longitudinal tunnel (302), a pair of lateral longitudinal beams (303), connected to the front floor structure (301) and to the front body sub-unit (2) and two intermediate longitudinal beams (L) which connect the central floor sub-unit (3) to the front body sub-unit (2) and which extend at intermediate areas between the lateral longitudinal beams (303) and the central tunnel (302). The intermediate longitudinal beams (L) are connected to the upper surface of the front floor structure (301) and have portions which extend in a cantilever fashion from the front edge of the front floor structure (301) and which are connected to said front body sub-unit (2). Due to this feature the floor structure has a lower surface which is substantially close to a regular continuous surface, so as to reduce turbulences in the air flowing under the floor panel structure during travel of the motor-vehicle, with a resulting positive impact on fuel consumption.
