A vehicle includes a body, a bumper and a plurality of self-tapping fasteners. The body defines mounting orifices. The bumper has an exterior shell that includes an interior wall. The interior wall has receiving portions that protrude inward relative to the shell such that the receiving portions are thicker than adjacent portions of the interior wall. Each of the plurality of self-tapping fasteners extend through one of the orifices and into one of the receiving portions to secure the bumper to the body.

The invention relates to a sacrificial composite part (1, 10, 100) that absorbs the energy released at the time of a vehicle collision with an impacting object (2), said part consisting of an assembly of a plurality of cells (3, 30, 300), each cell comprising a wall (5, 50, 500) connecting a first end (6, 60, 600) and a second end (7, 70, 700) of said cell, the direction of penetration (8) of the impacting object into said part going from said first end to said second end. Said sacrificial composite part of the invention is characterized in that that peripheral wall of each cell has a decreasing thickness (e) from said first end towards said second end of said cell, in the direction of penetration of the impacting object.

A lower stiffener is provided for a bumper of a vehicle. The lower stiffener is mounted on a lower portion of a bumper beam or a front end module (FEM) carrier of the vehicle. The lower stiffener includes a pair of core portions formed by extending in a width direction of the vehicle in an elongated loop shape corresponding to a shape of the bumper of the vehicle, and arranged parallel to each other at a regular interval. A pair of molding portions surrounds the core portions, respectively and a connection portion connects and integrates the pair of molding portions with each other.

A vehicle includes a body, a bumper and a plurality of self-tapping fasteners. The body defines mounting orifices. The bumper has an exterior shell that includes an interior wall. The interior wall has receiving portions that protrude inward relative to the shell such that the receiving portions are thicker than adjacent portions of the interior wall. Each of the plurality of self-tapping fasteners extend through one of the orifices and into one of the receiving portions to secure the bumper to the body.
