      8. By using the following structures, resonance tuning of the dash panel and floor pan has been implemented. As a result, superior Noise, Vibration, Harshness (NVH) performance is ensured.


        • No. 3 floor cross member sub-assembly is provided.

        • A dash panel to cowl brace is provided.

        • Dash sandwich sheet steel is provided, in which the dash panel insulator sheet and dash panel insulator sheet LH are sandwiched by the dash panel and rear dash panel in the driver seat side, and the dash panel insulator sheet RH is sandwiched by the dash panel and No. 2 dash panel in the front passenger side.

        • The bead shape and the location of the center floor pan and rear floor pan have been optimized.

        • The sheet thickness of the center floor pan has been optimized.
