In order to produce different motor vehicles of a vehicle type, which have the different drive concepts of an internal combustion engine, electric motor or a combination of an electric motor and an internal combustion engine, two different floor pan assemblies and two different luggage compartment floor subassemblies are provided. The two subassemblies are each produced using different deep-drawing dies. A combination of one of the two floor pan subassemblies with one of the two luggage compartment floor subassemblies allows the production of motor vehicles for all three drive concepts. The first of these two floor pan subassemblies, when installed in the vehicle, has a higher position than the second floor pan subassembly. The higher floor pan subassembly is used to produce both the electric-drive motor vehicles and hybrid-drive motor vehicles. A large-area installation space below the floor pan subassembly is also made available for the hybrid-drive motor vehicles for housing at least one pack-type battery.

A reinforcement extending in the front-back direction of a vehicle and connecting a rear side member and a center pillar is provided. The reinforcement includes a gusset, an intermediate connecting member, and a pillar-side member. The gusset is connected to the rear side member, and the front end portion of the gusset is connected to the rear surface of the intermediate connecting member. The front surface of the intermediate connecting member is connected to the rear end portion of the pillar-side member. The pillar-side member is connected to the center pillar.

A front-side cross member and a rear-side cross member in a front portion of a rear floor are spaced apart from each other, on a top side of the rear floor, ends of the front-side cross member in the vehicle width direction are connected to respective lower ends of left and right brace members extending up and down, while the rear-side cross member is disposed on the rear floor from an underside of the rear floor. A high voltage component is disposed on a top face in the front portion of the rear floor between the front and rear-side cross members, the high voltage component is disposed rearwardly spaced apart from the front-side cross member and closer to the rear-side cross member, and the high voltage component is attached to the front-side cross member via a bracket that deforms under a load in the vehicle front-rear direction.

A vehicle body rear part includes a side sill, a rear wheel house, a rear side frame, and a close plate. An outer curve part and an inner curve part are provided in a region close to a front part of the rear wheel house of the rear side frame. An outer ridge line that extends straight in a vehicle forward direction from a position substantially directly above the vicinity of a rear end portion of the outer curve part of the rear side frame and an inner ridge line that extends to be curved to a vehicle forward side substantially along the inner curve part at a position substantially directly above the inner curve part of the rear side frame are provided on the close plate. The outer ridge line and the inner ridge line converge in an inner region in the vehicle width direction of a joint part of the rear side frame and the side sill.

Shock absorber assembly structures are disclosed. An example apparatus disclosed herein includes a body of a vehicle having a first longitudinal structural member adjacent a wheel arch area of the body, a first locating rib integrally formed in the first longitudinal structural member to position a shock absorber of a chassis of the vehicle during assembly of the vehicle body to the chassis, and a first attachment boss integrally formed in the first longitudinal structural member adjacent to the first locating rib to receive a first fastener to fasten the shock absorber to the body.

A vehicle rear structure includes: a fuel tank arranged between a pair of side members; and a floor panel. The floor panel includes: a front floor panel and a rear floor panel that cover an upper surface and a rear surface of the fuel tank. and that have a roof section located above height positions of flanges of the side members. The rear floor panel has: a bottom surface located below the height positions of the flanges of the side members; rear vertical wall sections raised upward from both of left and right sides of the bottom surface; and rear flat sections folded to the left and the right at upper ends of the rear left and right vertical wall sections and joined to upper surface sides of the flanges on a vehicle inner side of the pair of side members.

A body for a vehicle configured for securing safety performance and vehicle rigidity according to a vehicle collision while increasing a battery capacity mounted in the vehicle, may include an internal side member mounted on a top surface of a center floor in a longitudinal direction of the body; a battery cross member mounted in a width direction of the body inside a battery case provided at a lower end portion of the center floor while intersecting the internal side member; and a coupling structure coupled to the battery case, the battery cross member, and the center floor at a point where the internal side member and the battery cross member intersect.

A rear vehicle-body structure for increasing support rigidity for a rear suspension and consequently increase steering stability. The rear vehicle-body structure includes a first frame extending to connect a rear end lower portion of a combined body composed of a side sill and a pillar and a lower arm front support portion of a rear side housing, and having therein a closed cross-sectional space; a second frame extending to connect a rear end lower portion of a floor tunnel located at a vehicle-width-direction center portion of a vehicle-body bottom portion and bulging toward a vehicle upper side in a vehicle front-rear direction and the lower arm front support portion and having therein a closed cross-sectional space; and a third frame extending to connect a rear end upper portion of the floor tunnel and the lower arm front support portion, and having therein a closed cross-sectional space.

A method of assembling a unibody vehicle includes securing a cab back panel of a cab back panel directly to an upturned flange of a cargo box floor. A unibody vehicle assembly according to another exemplary aspect of the present disclosure includes, among other things, a cab back panel, a cargo box floor, and a passenger compartment floor. The cab back panel is secured directly to the cargo box floor. The cab back panel provides a back wall of a passenger cab and a front wall of a cargo area.

A vehicle body rear part includes a side sill, a rear side frame, a cross member, a trailing arm, an arm attachment bracket, and a close plate. In the trailing arm, a front end part is swingably supported via a mount member at a front region of the rear side frame. The arm attachment bracket is fixed into a cross section of the rear side frame and has a fixation nut with which the mount member is fastened and fixed. The bracket reinforcement member reinforces the arm attachment bracket. The close plate closes an opening on an upper side of the front region of the rear side frame. End parts on both sides in the vehicle width direction of the bracket reinforcement member are joined to the side sill and the cross member, and an upper part of the bracket reinforcement member is joined to the close plate.
