Abstract

The invention relates to a car body structure, especially a substructure, for a motor vehicle, with beam components that create defined load paths in collision situations. According to the invention, the beam components situated in the area of at least one defined load path—especially a head-on collision load path and/or a side collision load path and/or a rear-end collision load path—at least partially comprise high-strength beam components, preferably completely through-hardened or at least partially through-hardened high-strength beam components, made out of a hot-worked or press-hardened steel sheet, said beam components being joined to each other directly or indirectly, preferably directly, especially being joined to each other positively or non-positively and/or by bonding.
