A chassis auxiliary-frame arrangement on a preferably self-supporting vehicle body is designed for improving the safety in a crash in such a manner that, in a frontal impact of the vehicle, the deformation zones of the vehicle body can be adequately and uniformly deformed without interference from the chassis auxiliary frame in order thereby to achieve a greater effective crash length of the deformation zones of the body. For this purpose, the chassis auxiliary-frame has devices for fastening it to the vehicle body, which devices, during a frontal impact of the vehicle, are completely detached above a certain degree of deformation of the deformation zones of the body, the chassis auxiliary-frame is therefore completely decoupled from the body and is pushed under the passenger cell 9 by means of a ramp.
