    1. Safety Features


      1. Impact Absorbing Structure for Frontal Collision


        1. The front side members utilize ultra high tensile strength steel in a construction to absorb and disperse energy in a frontal collision.

        2. The use of under members enables a construction that disperses load from the radiator supports.

        3. Door beltline reinforcements are strengthened to optimize dispersal of collision energy to the front pillar, door beltline, and rocker panel.

        4. The use of a crossmember in the dash panel enables a construction that disperses load from the front side members to the floor member and upper body.

        5. The use of members on the front floor at the sides of the tunnel enables a construction that achieves tunnel strength and dispersal of load from the front side members.

        6. Impact absorbing pads with sound absorbing performance are installed to the vehicle body from the lower surface of the dash panel to the front of the floor as a measure to reduce leg injuries in a collision.

      2. Impact Absorbing Structure for Side Collision


        1. Ultra high tensile strength steel is used for the center pillar outer reinforcement, center pillar hinge reinforcement, rocker panel inner reinforcement, rocker panel outer reinforcement and roof center reinforcement to ensure high strength.

        2. Bulkheads are placed on both sides of the No. 1 and No. 2 floor cross members and center floor side crossmember to efficiently transmit impact load from the impact beam to the floor crossmembers.

        3. The use of roof reinforcements enables a construction that transmits load to the opposite side of the vehicle in a collision.

        4. Optimal placement of the impact protect beams enables a construction that efficiently transmits load.

        5. The impact support box is optimally placed on the front floor between the driver seat and front passenger seat to ensure that load is transmitted from the center pillar to the seat pipe, impact support box, and seat pipe on the opposite side, thus helping secure sufficient survival space.

    2. Aerodynamics


      1. Aero Stabilizing Fin


        1. Aero stabilizing fins are provided on the front passenger door, driver door and on each rear combination light lens for enhanced aerodynamics.

        2. After passing the aero stabilizing fin, the air speed will increase and a vortex will be generated.

        3. This vortex increases the speed of the surrounding air while at the same time pulling the airflow towards the vehicle body.

        4. The airflow with higher speed passes near both sides of the vehicle body and ends at the rear of the vehicle. This helps to hold the vehicle body, and thus stabilizes the vehicle.
