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
-
• The overall body rigidity has been improved using a three-ring structure in 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.
Fail-safe
• Not applicable
