Abstract
The invention relates to a front end of a motor vehicle, comprising a bumper crossmember (2) and a bumper skin, the bumper skin being positioned opposite the crossmember (2) and defining an internal space (3) between the bumper skin and the crossmember (2). The front end comprises a first bumper element (4) extending from the crossmember (2) onto an upper portion of the front end, and a second bumper element (7) extending from the crossmember (2) onto a lower portion of the front end. The front end comprises at least one stiffening element (12) extending into the internal space (3) and designed to stiffen the bumper skin. Each stiffening element (12) connects the first (4) and second (7) elements and is foam-free. The invention also relates to a front end. (Figure 2)
