    1. Safety Features


      1. Impact Absorbing Structure for Frontal Collision


        • High strength steel is used in the tunnel reinforcement to help prevent the cabin from deforming in a frontal collision.

        • In the offset frontal impact shown, the dash crossmember makes the difference between displacement of the LH side (impact side) and RH side smaller.

      2. Impact Absorbing Structure for Side Collision


        • 3 layers of high tensile steel are used in the center pillar reinforcements, thus realizing a highly rigid center pillar construction.

        • The roof creates a cross-car load path from the center pillar to minimize rail area intrusion.

        • The roof uses closed section high tensile steel roof reinforcements for increased load capacity, minimizing rail area intrusion.

        • A center floor crossmember is used for the rear seat area floor gusset in conjunction with the door boxes to create a cross-car load transfer path, reducing intrusion.

        • Energy absorbing pads are used inside the doors to dampen the impact energy of a side collision.


        • In addition, seat pipes are provided in the seat cushion frames and reinforcements are used above the floor tunnel so that the seats can be utilized as structural materials to minimize the body deformation during a side collision.

    2. Low Vibration and Low Noise Body


      1. The body insulation material layout is optimized to ensure efficient and effective wind, road, and external airflow noise reduction inside the cabin.

      2. Damping sheets are used for the front pillars to reduce noise intrusion in the cabin.

    3. Aerodynamics


      1. The front bumper, point of the engine hood, shape of the rear bumper and rear spoiler all help to prevent disturbance of the airflow around the vehicle.


        • By reducing the height of the front bumper from the ground and making the sides of the body smooth, the airflow to the sides and under the vehicle has been rectified.


        • All of the air from the front openings of the front bumper passes through the radiator.

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

  2. CONSTRUCTION


    1. Lightweight and Highly Rigid Body


      1. High strength sheet steel and ultra high strength sheet steel are used in order to realize excellent body rigidity and a lightweight body.

    2. Rust-resistant Body


      1. Anti-corrosion sheet steel is used as shown in the following illustration:

      2. To protect the paint from chipping while the vehicle is being driven, anti-chipping paint is applied to the front end of the hood panel.

      3. Rocker protectors and anti-chipping tape are applied to protect the body from chipping while the vehicle is being driven.
