A body structure of a passenger car comprises a front wall arranged between the forward car section and the passenger compartment, two mutually spaced side rails which are each connected to a floor support which is situated behind and extends as an extension of the side rail, exterior side members, upright hinge pillars and a floor. In order to, on the one hand, provide a stiff passenger compartment and, on the other hand, absorb the forces well which occur in the case of a frontal impact and introduce these forces in a large-surface manner from the forward side rails into the adjoining, partially lower body structure, it is provided that the two lower forward side rails extend continuously to the front wall and are connected to a first cross member fitted on the exterior side onto the front wall, and in that, at the front wall, at the height of the first cross member on the side facing the passenger compartment, a second cross member is arranged which, in the center area of its transverse course, is connected with a tunnel reinforcement fitted onto the transmission tunnel, and which--viewed in the vertical direction--widens in its laterally exterior areas in the downward direction…
