A chassis-subframe is attached to a vehicle body and is connected via a plurality of fastening means to high load-bearing body parts. The chassis subframe is connected to the load-bearing body parts by the fastening means indirectly via a sacrificial plate. From a specific relative force acting substantially in the vehicle longitudinal direction between the chassis subframe and the sacrificial plate, the fastening means is pulled out of said sacrificial plate, immediately in the case of a displacement movement of the chassis subframe occurring to the rear, viewed in the vehicle longitudinal direction. The fastening means are arranged by means of the sacrificial plate relative to the load-bearing body parts such that, after being pulled out, the fastening means are able to move freely to the rear in the vehicle longitudinal direction, without interacting with the, or another of the, load-bearing body parts.
