Abstract: A vehicle body structure includes: a first frame that is formed of a first material and has a closed cross section; and a second frame that is formed of a second material and has a closed cross section. The first frame and the second frame are aligned with each other in a vehicle longitudinal direction. The second frame has higher tensile strength and is lighter than the first frame. In a front cross-sectional view of the vehicle, a second center associated with the second frame is located on an outer side in a vehicle width direction from a first center associated with the first frame with respect to vehicle center.

Abstract: An exhaust system member is provided on a vehicle-width-direction outer side relative to a vehicle body structure such as a side sill, while avoiding widening of the vehicle, enhancing shock absorption performance during a collision, and maintaining rigidity of the vehicle body. Embodiments include an engine disposed forward of a vehicle cabin, an engine exhaust system, and a hinge pillar extending vertically. The exhaust system includes a first exhaust system member beside the hinge pillar in the vehicle front-rear direction from the vehicle-width-direction outer side of the hinge pillar and extending forward of the hinge pillar, a second exhaust system member rearward of the hinge pillar, and a connection part connecting these exhaust system members. The connection part has a smaller length in the vehicle width direction than at least one of the first and second exhaust system members, and overlaps with the hinge pillar in the vehicle front-rear direction.

Abstract: An exhaust system member is provided on a vehicle-width-direction outer side relative to a vehicle body structure on the side of a floor, while avoiding widening of the vehicle and preserving small overlap collision resistance. Embodiments include an engine disposed forward of a partition wall defining a front edge of a vehicle cabin, an exhaust apparatus, a side sill extending along the vehicle front-rear direction on the side of a floor forming a floor surface of the vehicle cabin, and a hinge pillar extending vertically from the side sill. A frame member extends toward the vehicle front side from the hinge pillar and has a front end, on the rear side of a vehicle wheel, overlapping with a vehicle-width-direction length area of the wheel. The exhaust system member is in an area on the vehicle-width-direction outer side of the frame member and on the front side of the hinge pillar.

Abstract: A trunk panel comprises a bottom portion, a first standing wall portion, and a second standing wall portion. A protrusion portion is provided at a rear end portion of the bottom portion and the second standing wall portion to protrude upward. This protrusion portion is spaced apart from the first standing wall portion such that a passage is formed between the protrusion portion and the first standing wall portion, wherein the passage is configured to allow water to flow down from a portion of the bottom portion which is located forward of the protrusion portion toward a rear end portion of the bottom portion and the second standing wall portion. Thereby, any bad influences of rainwater or the like, which may be brought to various kinds of members around or arranged below a rear lamp, can be properly restrained.
Abstract translation: 主干板包括底部，第一立壁部分和第二直立壁部分。 突起部设置在底部的后端部和第二立壁部上方突出。 该突出部分与第一直立壁部分间隔开，使得在突出部分和第一直立壁部分之间形成通道，其中通道构造成允许水从位于底部的底部的一部分向下流动 突出部的前方朝向底部的后端部和第二立壁部。 因此，可以适当地抑制可能对后灯的周围或布置在各种各样的构件上的雨水等的任何不良影响。

Abstract: A vehicle body side structure is provided where an exhaust apparatus is located on the vehicle-width-direction outer side relative to a side sill without widening the vehicle. Embodiments include an internal combustion engine equipped on the front side of a partition wall defining a front edge of a vehicle cabin space, an exhaust apparatus through which exhaust gas exhausted from the internal combustion engine passes, and a side sill extending along the vehicle front-rear direction on the side of a floor forming a floor surface of the vehicle cabin space. The side sill has a recess having a cross section recessed toward the vehicle-width-direction inner side from the vehicle-width-direction outer side in a cross-sectional view orthogonal to the vehicle front-rear direction and extending in the vehicle front-rear direction, and an exhaust system member provided in the exhaust apparatus is disposed at the recess.
