A vehicle body front structure includes paired left and right front side frames extending in a vehicle front-rear direction and a crossmember that extends in a vehicle width direction and is suspended between the paired left and right front side frames. The front side frames respectively have side frame bend portions at rear portions thereof, the side frame bend portions bending inward in the vehicle width direction, and at least one of end portions of the crossmember in the vehicle width direction is connected to a corresponding one of the side frame bend portions.

An interlocking body and floor pan assembly for a below-floor energy stored vehicle includes a vehicle structural assembly having a front compartment section connected to a rear compartment section using first and second rocker members. The front compartment section includes a compartment front cross-beam and the rear compartment section includes a compartment rear cross-beam oriented parallel to the compartment front cross-beam. The vehicle structural assembly defines a bucket configuration having faces of the compartment front cross-beam and the compartment rear cross-beam angularly oriented from an upper outboard edge downwardly pitching to a lower inboard edge. A prefabricated sub-floor assembly seats on flange structure and is positioned with a clearance to the bucket configuration of the vehicle structural assembly. An outer perimeter of the sub-floor assembly is larger than an inner perimeter of the vehicle structural assembly where the sub-floor assembly contacts the vehicle structural assembly.

A vehicular under cover includes an oblong hole-shaped through-hole and is assembled to a lower side of a vehicle so as to cover a lower part of the heat source. In a plan view, the through-hole is formed so that a longitudinal direction of the through-hole is inclined with respect to a front-rear direction of the vehicle. The inclination excludes an orthogonal direction to the front-rear direction of the vehicle.

A vehicle assembly method includes assembling a chassis platform, mounting a floor pan to the platform, mounting a modular interior to the floor pan, assembling a body top-hat separate from the platform and the floor pan, and mounting the body top-hat to the platform and the floor pan after mounting the modular interior to the floor pan.

A floor center member extends through a central part of a body floor of a vehicle and along a longitudinal direction of the vehicle, and a first floor cross member penetrates the floor center member to extend in a lateral direction of the vehicle. A reinforcing member extending in the longitudinal direction of the vehicle is disposed on the interior of the floor center member and above the first floor cross member.

A side rail assembly connected to a battery tray in a motor vehicle includes a side impact rail having a first portion with a first strength, a second portion with a second strength, the second portion spaced apart from the first portion, and a third portion with a third strength, the third portion connected to the first portion and the second portion. The third strength is greater than the first strength and is greater than the second strength.

A vehicle body for an electrically driven vehicle, having a vehicle frame for transmitting mechanical forces during the operation of the vehicle. The vehicle frame has a battery portion for receiving at least two battery modules, and the battery portion has at least one fastening interface for fastening the at least two battery modules in the received position.

A vehicle frame may comprise a plurality of interlocking tab and slot frame members forming a three-dimensional structure. A custom vehicle frame construction may be specified, designed and built based on a purchaser's selection. The three-dimensional structure may comprise a tab and slot panel to which additional tab and slot frame members are attached. The tab and slot frame members may have an attachment device disposed thereon for attachment of a vehicle component selected by the purchaser of the vehicle frame.

An intake and exhaust device (1) for a vehicle engine is capable to perform a compression self-ignition operation, the device comprising on an intake passage a supercharger (9) driven by a force other than an exhaust gas, wherein an exhaust purification device (18) disposed on an exhaust passage is disposed adjacent to an outer surface of the engine (2).
