  1. FUNCTION


    1. Safety Features


      1. Impact Absorbing Structure for Frontal Collision


        1. Through the adoption of a body structure that disperses collision energy to multiple frame components, collision energy is efficiently absorbed to suppress cabin deformation.

        2. The front side members are utilized to absorb and disperse energy in a frontal collision.

        3. Door beltline reinforcements are strengthened to optimize dispersal of collision energy to the rocker panel and floor panel.

      2. Impact Absorbing Structure for Side Collision


        1. Through the adoption of a body structure that disperses collision energy to multiple frame components, collision energy is efficiently absorbed to suppress cabin deformation.

        2. The center pillars are strengthened to optimize dispersal of collision energy to the rocker panel and roof reinforcement.

        3. The use of roof reinforcement and floor crossmember 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.

    2. Aerodynamics


      1. Aero stabilizing fins are provided on the outer rear view mirror bases for enhanced aerodynamics.


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

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

        3. 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, thus stabilizing the vehicle.

      2. Various types of airflow routing parts are provided under the floor to control airflow. In addition, an undercover is provided to make the under body flat in order to ensure excellent aerodynamic performance.

      3. A fin-shaped engine under cover and rear under cover have been adopted to achieve higher diffuser efficiency, ensuring stability.
