Purpose

•The following structures have been adopted to absorb impact efficiently in the event of a collision and to suppress cabin deformation.
―Straight structure which achieves both high strength and weight reduction
―Multi-load path structure which assures a high level of collision absorption
―Ring structure which enhances overall rigidity
•A cross-shaped sectional front bumper reinforcement crush can and front side frames have been adopted which effectively absorb impact energy during a frontal collision and suppress cabin deformation.

Construction


Straight structure

•The straight-shape frames create a continuous configuration from the front to the rear.

Multi-load path structure

•Impact energy in a collision is dispersed in multiple directions and absorbed effectively.
•To disperse and absorb frontal impact energy at the engine compartment, the following three paths have been established at the vehicle front (front frame).
Upper path
―The upper path disperses and absorbs frontal impact energy from the front frame to A-pillar.
Mid path
―The mid path disperses and absorbs frontal impact energy from the front frame to the side body and floor.
Lower path
―Not only the body parts, the front crossmember is also used to absorb impact energy. The lower path disperses and abosrbs frontal impact energy from the front frame to B frame.

Cross sectional shape

•Even using a steel plate of the same thickness, the strength can be enhanced by increasing the number of ridges. By utilizing this characteristic, the cross-section of the front bumper reinforcement crush can and front side frames is cross-shaped, achieving both high impact energy absorption and weight reduction.

Ring structure

•Overall body rigidity has been improved using four ring structures created by the upper body including the roof rail and B-pillar combined with the underbody reinforcements.
•Cabin deformation in a collision is suppressed by creating a ring structure.
