BODY STRUCTURE


  1. CONSTRUCTION


    1. Lightweight and Highly Rigid Body


      1. High-tensile strength steel, ultra high-tensile strength steel, hot-stamped steel and aluminum are used in order to achieve excellent body rigidity and a lightweight body.

      2. Along with the use of high-tensile strength sheet steel, the inner windshield header panel is structured with closed cross-sections, thus ensuring superior roof strength.

      3. Hot-stamped steel (1470 MPa class), ultra high-tensile strength sheet steel (980 MPa class) and high-tensile strength sheet steel (590 MPa class) are used for each pillar, realizing a low center of gravity design, and ensuring roll over performance.

      5. A front upper pillar door opening gusset, which connects the apron member portion and the front pillar portion, is provided in the front fender portion. As a result, a superior steering feel and roll feeling are ensured. In addition, to avoid a reduction in collision safety, a bead shape is provided to allow for a structure which is easily deformable in a collision.
