    1. Impact Absorbing Structure for Frontal Collision


      1. A structure that ensures collision energy absorption efficiency, dissipates impact and minimizes cabin deformation during a frontal collision has been achieved.


        • The front crash box and front side member sub-assembly absorb and disperse collision energy received from the front bumper reinforcement.

        • Collision energy applied to the front side member sub-assembly is transmitted to the front apron to cowl side member sub-assembly and cowl under section.

        • The front lower side member and lower side members absorb and disperse collision energy received from the radiator support lower cross member.

        • Collision energy applied to the lower side members is transmitted to the front suspension cross member and floor panel.

        • Front body pillars have been strengthened to optimize dispersal of collision energy to the rail panel, rocker panel and floor panel.

        • Collision energy applied to the front body pillar transmitted to the instrument panel reinforcement and cowl panel circular structure via the instrument panel reinforcement cowl side bracket.

    2. Impact Absorbing Structure for Side Collision


      1. A structure that ensures collision energy absorption efficiency, dissipates impact and minimizes cabin deformation during a side collision has been achieved.


        • Hot-stamped sheet steel is used for the roof cross reinforcement CTR, front body pillar outer reinforcement, rail outer reinforcement, center pillar outer reinforcement and center pillar hinge reinforcement.

        • A structure which uses the floor side member reinforcement and rocker inner side panel to efficiently transmit impact load during a side collision to the floor is used.

        • A structure which optimizes the placement of the rear door protection beam sub-assembly and rocker panel reinforcement to efficiently transmit impact load is used.

    3. Roof Crush Resistance


      1. Loads are supported by the front body pillar, center body pillar, roof and header during a roof crush.


        • Hot-stamped sheet steel is used for the roof cross reinforcement CTR during a roof crush.

        • High-tensile strength sheet steel is used for the front body pillar inner reinforcement and front header lower panel.

        • An integrated construction between the upper and lower parts of the center body pillar are used. For both of them, high-tensile strength sheet steel is used, thus ensuring the rigidity of the center body pillar during a roof crush.

    4. Reduction Pedestrian Head Injury


      1. The following shape is used for around the front body, thus maintaining necessary rigidity and aiming for a reduction of impact against a pedestrian in a collision with a pedestrian.


        • The hood panel uses a structure which ensures an impact absorption stroke at the front between the upper radiator support and hood inner panel reinforcement in order to reduce the impact to the pedestrian whose head struck the hood.

        • The parts surrounding the cowl top ventilator louver sub-assembly use a crushable structure to improve the rate of energy absorption from the estimated collision direction to reduce the impact to the pedestrian whose head, etc., struck the area. The structure of the cowl top ventilator louver sub-assembly maintains the necessary rigidity while having a lowered deformation strength in order to absorb impact load.
