BODY STRUCTURE DETAILS LOW VIBRATION AND LOW NOISE BODY

CONSTRUCTION

1. Sound Absorbing and Vibration Damping Materials

   1. A hood insulator is provided on the hood sub-assembly. This achieves excellent sound insulation performance.

2. Under Body Structure

   1. Ride comfort has been enhanced by implementing the following measures that control the shape of the body to reduce body vibration.

      1. The front floor panel surface has been given a curved shape.

      2. A reinforcement has been added to on the floor tunnel panel.

      3. Bulkheads have been added to on the lower portion of the center pillars.
