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.
A front side member to dash panel cross member 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 rear 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 dash panel has been optimized.
The sheet thickness of the center floor pan has been optimized.

By reducing the level differences between the windshield glass and the roof panel, aerodynamic characteristics have been ensured and wind noise has been reduced.
The differences between the outside windshield molding and windshield glass, the thickness of the side outer panel and the corner shape of the side outer panel have been optimized to suppress wind noise.
A front fender side panel protector is provided between the side outer panel and the front fender panel. This prevents road noise from entering the cabin, and achieves superior quietness.
A hood to front fender seal is provided to suppress wind noise on the periphery of the front fender panel and hood sub-assembly.
