Low Vibration
Low Vibration and Low Noise Body1. General
Excellent sound insulation performance has been achieved through the use of sound insulation materials such as the dash panel silencer, hood silencer, expandable foam in the pillars, damping materials such as asphalt sheet, and through the double-sealing of the front doors, in addition to the high-performance body construction. A high level of noise vibration performance has been achieved by controlling the resonance frequency through the use of mass dampers and dynamic dampers and controlling the airflow around the vehicle through the use of optimally shaped moldings, spats in front of the tires, and fender seals.
2. Sound Absorbing and Vibration Damping Materials Dash Panel Silencers
^ Silencers have been provided on the sides of the dash panel facing the cabin interior and exterior to reduce engine noise.
^ A lightweight material with enhanced sound absorption characteristics has been adopted for the inner silencer facing the cabin interior to reduce noise in the vehicle interior.
Hood Insulator
A hood insulator has been provided under the engine hood to reduce engine noise.
Expandable Form & Mass Damper
Mass dampers and expandable foam have been provided in various areas of the body to achieve excellent sound insulation performance.
Asphalt Sheet
^ Damping materials have been optimally allocated to efficiently reduce noise and vibration.
^ Asphalt sheet has been adopted on the front floor~
^ Spray-type damping coat has been adopted on the rear floor~
Door Mirror
The mounting base of the door mirror has been filled with expandable foam to improve its noise and vibration performance.
Rear Wheel-house Sandwich Panel
A sandwich panel has been provided in the rear wheelhouse area to reduce road noise.
3. Weather Strip
Front Door and Slide Door Opening Trim Weather Strip
The openings of the front door and the slide door are sealed with a door opening trim weather-strip and a door weather-strip to enhance sound insulation performance.
4. Sub-frame Structure
Double rubber element
The engine and the transmission are mounted on the front suspension, and the lower arms and the steering rack are mounted via the front suspension member. These double vibration isolation measures on the body have been taken to reduce engine and road noise.
Dynamic Damper
A dynamic damper has been provided on the front suspension member to reduce the booming noise created by the engine.
5. Wind Noise
Windshield Molding
^ A flush-type windshield molding is used to prevent wind noise.
^ Windshield wiper is hidden by hood to keep out of airflow to improve wind-noise.
Spats
Spats have been provided on the front and rear fender liners to improve the airflow around the front and rear tires.
Fender Seal
A fender seal is added to improve front cabin noise level.
Glass Thickness
Glass with an optimal thickness has been selected for each window in order to achieve the proper balance in terms of noise and vibration.
