a vehicle body comprising an inner shell , an outer shell , a floor plate and a chassis , wherein the inner shell , the outer shell and the floor plate are indirectly or directly interconnected and form a passenger compartment , the rigidity , especially the torsional rigidity and / or the flexural rigidity , of the vehicle body is to be ensured without additional components or process steps . furthermore , the vehicle body is to be inexpensive to manufacture . the foregoing is achieved by the fact that at least one interior component is connected to the inner shell and / or the supporting structure in such a manner that it contributes to the rigidity , especially the torsional rigidity and / or the flexural rigidity , of the vehicle body .
