The body of the motor vehicle has a reinforcing section (7) in one area of the longitudinal member (1). It runs in front of and behind the front wall (2). The longitudinal member runs with height displacement from a forward structural area (3) to below the floor plate (4) and therefore has an inclined height compensating area (6).The reinforcing section, in the area of the floor plate adjacent to two outwards pointing side attachment flanges, lies upon the upper edge of the longitudinal member.
