Abstract: The vehicle underbody structure comprises a floor panel, at least one longitudinal beam extending in a longitudinal direction of the vehicle under said floor panel and at least one transversal beam extending in a transversal direction, substantially perpendicular to the longitudinal direction, above the floor panel, the floor panel extending transversally between two sides, the transversal beam comprising a transversal central end extending under a central area of said floor panel and a transversal side end extending at one of the sides of said floor panel, wherein the transversal beam comprising a central portion, extending between the central end and an intermediate part of the transversal beam, and an end portion, extending between the intermediate part and the side end, the resistance to plastic deformation of the central portion being greater than the resistance to plastic deformation of the end portion, and in that the intermediate part of the transversal beam extends upright of the longitudinal beam such that the end portion of the transversal beam extends transversally between the longitudinal beam and one of the sides of the floor panel.

Abstract: A vehicle underbody structure containing a floor panel, at least one longitudinal beam extending in a longitudinal direction of the vehicle under said floor panel and at least one lowerside sill part extending in the longitudinal direction adjacent to the floor panel, and at least one reinforcement element extending in a transversal direction, substantially perpendicular to the longitudinal direction, said reinforcement element made of a press hardened steel part having a tensile strength higher or equal to 1200 MPa and extending under the floor panel and being attached at one of its transversal ends to the longitudinal beam and at the other of its transversal ends to the lowerside sill part is provided. A vehicle body including the vehicle underbody structure is also provided.

Abstract: The vehicle front body structure (2) comprises an upper longitudinal beam (10, 12) and a reinforcing element (14, 16) for reinforcing the wheel casing of the vehicle, said reinforcing element (14, 16) extending in a longitudinal direction substantially parallel to the upper longitudinal beam (10, 12), said upper longitudinal beam (10, 12) comprising an attachment portion (40), comprising an attachment area for attaching a connecting element (8) joining the upper longitudinal beam (10, 12) to a lower beam (22, 24) of the vehicle. The vehicle front body structure (2) further comprises a linking element (18, 20) joining the reinforcing element (14, 16) and the upper longitudinal beam (10, 12). The linking element (18, 20) is attached to the attachment portion (40) of the upper longitudinal beam (10, 12).
