Abstract: The invention relates to a motor vehicle body, the support structure (10) of which is composed of large-size partial modules (12, 34, 50, 66), a basic module (12) comprising lateral longitudinal members (15) and a body floor (14) and reaching laterally as far as front wall columns (20), and, when the support structure (10) is assembled, the basic module (12) being connected to a front end module (34) which belongs to the front crumple zone of the motor vehicle and is supported in a crash stable manner on the basic module (12). In order to provide a motor vehicle body, in which the front end module (34) even without a roof construction is fixed in a sufficiently stable manner on the basic module (12), a front end region (36) of the body floor (14) belongs to the front end module (34) and extends rearward over a considerable length region of the basic module (12) between lateral longitudinal member sections (16).

Abstract: A support structure of a motor vehicle, e.g., a passenger car, having a floor which, in the longitudinal vehicle direction, evolves into an upwardly extending end wall, and having an extension which is attached to the end wall by longitudinal members. The production of the support structure may be simplified by arranging the longitudinal members as profiles having a constant cross-section in their longitudinal direction, their longitudinal profile direction being inclined relative to the longitudinal vehicle direction.
