A vehicle front section structure includes left and right front side frame. A deformation portion configured to undergo compression deformation in the vehicle front-rear direction at a time of head-on collision of the vehicle is provided at a front end portion of each of the left and right front side frames. Left and right front side members that support a floor section of a vehicle cabin extend along the vehicle front-rear direction at a vehicle upper side with respect to the left and right front side frames. Front sections of the left and right front side members and the corresponding left and right deformation portions are connected by left and right coupling members. The left and right coupling members are configured so as to more readily undergo plastic deformation under collision load at a time of head-on collision than the left and right front side members.

A vehicle front section structure includes: a power unit installed at a front section; a left and right pair of front side frames extending in a vehicle front-rear direction; a left and right pair of front side members extending in the vehicle front-rear direction at a vehicle upper side of the left and right pair of front side frames, with rear end portions of the front side members being respectively joined to the left and right pair of front side frames; a cross member disposed at a vehicle rear side and obliquely upward of the power unit so as to span between the left and right pair of front side members and to support a driving seat of the vehicle; and a reinforcement brace spanning between the cross member and at least one front side member of the left front side member or a right front side member.

A structural support system for a vehicle having a longitudinal axis extending from a front of the vehicle to a rear of the vehicle includes a cradle configured to support an engine of the vehicle, a structural side rail assembly having first and second side rails, a first set of six cradle attachments coupling the cradle to the first side rail, and a second set of six cradle attachments coupling the cradle to the second side rail. A predetermined portion of the cradle attachments of both the first and second set of six cradle attachments are designed to intentionally detach during a frontal impact event to facilitate absorbing impact energy and reducing deceleration and passenger compartment intrusion.

The present impact absorbing member includes: a hat-shaped member having a hat top section; and a plate-shaped member facing the hat top section. A deformation guidance section is provided on a wall section of at least one of the hat top section and the plate-shaped member. The deformation guidance section includes: a first high strength section having relatively higher buckling resistance in the wall section; and a pair of low strength sections having relatively lower buckling resistance and arranged on both sides of the first high strength section therebetween in a view along the longitudinal direction. Furthermore, the impact absorbing member includes a pair of second high strength sections disposed on both sides of the deformation guidance section to be adjacent to the pair of low strength sections in a view along the longitudinal direction and having a higher buckling strength relative to the low strength sections.

A mounting system for mounting a tank to a space frame comprises a side mount configured to mount the tank to a center upper frame connection of the space frame, and a bottom mount configured to mount the tank to an elongate support member of the space frame. The bottom mount and the side mount are distinct mounts and configured to be mounted to the tank in a spaced apart relationship with respect to each other. The bottom mount and the side mount are coupled to a bottom and a rear side of the tank, respectively, and together are configured to mount the tank to the space frame.

A front vehicle-body structure of a vehicle is provided that allows for lower deceleration (so-called G) for occupants in the event of an oblique collision, which involves the largest load input, while restraining a load in a shear direction from being input to connecting portions of frames. A front vehicle-body structure of a vehicle includes a suspension housing formed with a suspension damper supporting portion, an upper arm supporting portion, and a lower arm supporting portion. A plurality of frames connecting the suspension housing and a vehicle cabin structural member are provided, and at least one frame of the plurality of frames is configured to be facilitated to break in a Z-shape in vehicle plan view in the event of an oblique collision.

A front pillar substructure that enables reduction in deformation of a front pillar. One embodiment of the present disclosure provides a front pillar substructure including a front pillar, and a rocker being joined to the front pillar. The front pillar includes an inner panel located inside with respect to the rocker, and an outer panel arranged so as to interpose the rocker between the inner panel and the outer panel. The outer panel includes an upper panel, and a lower panel overlapped with and joined to the upper panel, the lower panel extending downward with respect to the upper panel. The upper panel or the lower panel includes a bent section bending in the width direction when viewed from the front-rear direction, the bent section being located inside with respect to a joint region where the upper panel and the lower panel are joined.
