A vehicle includes a vehicle frame including a first frame rail and a second frame rail each elongated along a vehicle-longitudinal axis. The first frame rail is spaced from the second frame rail along a vehicle-lateral axis. The vehicle includes a bumper supported by the first frame rail and the second frame rail. The bumper includes a crossbeam elongated along the vehicle-lateral axis. The bumper includes a cell structure vehicle-forward of the crossbeam, the cell structure including cell walls that define cell chambers. The bumper includes foam disposed in the cell chambers.

A deformation element arrangement is provided for a motor vehicle, having a deformation element and a vibration-generating device. The vibration-generating device is arranged and designed in such a way that the deformation element, when required, can be set in vibration so that a deformation behavior and/or a flow behavior of the deformation element is/can be varied in accordance with a request condition.

A pedestrian contact detection apparatus, for a vehicle, includes a bumper beam, an absorber, an upper rib, a lower rib, a contact detection sensor, and a cover. The upper rib and the lower rib each protrude from a front face of the absorber toward a vehicle front side and each extend discontinuously in a vehicle width direction. The lower rib is disposed on a vehicle lower side of the upper rib. A pressure tube extends in the vehicle width direction and is disposed between the upper rib and the lower rib. The cover covers a front face of the absorber from the vehicle front side, includes a support having insertion holes through which the upper and lower ribs are disposed, and is disposed on the vehicle front side of and adjacent to the bumper beam. The support supports the pressure tube from a vehicle rear side.
