    Abstract: The invention deals with the design and the production method of a front floor reinforcement structure (1) for a vehicle (3) having a battery pack (5) in the tunnel (7) designed to improve the energy absorption of the vehicle during a side impact by involving the front floor panel (11) in the energy absorption during the side impact. The front floor reinforcement structure (1) comprises a front floor cross member (13) having a non-deformable portion (14) located on the end of the front floor cross member (13) closest to the side sill (9) and a deformable portion (16) located on the end of the front floor cross member (13) closest to the tunnel (7). The resistance to plastic deformation of the non-deformable portion (14) is greater than the resistance to plastic deformation of the deformable portion (16), which is itself greater than the resistance to plastic deformation of the front floor panel (11).
