Low Vibration and Noise Body

Sound Absorbing and Vibration Damping Materials





1 To achieve a body that excels in quietness, various types of silencers, which suppress the sounds that are transmitted from the engine or wheels, have been appropriately allocated.

1 A felt-type sound absorption material is provided on the back surface of the cowl to ensure pedestrian protection performance and improve quietness. Furthermore, reinforcements have been added to the lower part of the body to reduce the amount of sound created at the cowl.

1 Various types of asphalt sheets have been effectively allocated as floor silencers in order to reduce the amount of sounds that are transmitted from the engine or wheels, while reducing weight.





1 Foamed materials, vibration damping materials, and plastic formed foamed materials for blocking the cross sections are provided at the door opening areas of the side panels and the front header area. These materials reduce wind noise and the amount of sounds that are transmitted from the pillars.





1 Sound insulation and absorption materials have been allocated in accordance with the acoustic characteristics of the cabin in order to realize superior quietness and weight reduction.





Sand Splashing Noise Reduction Construction

1 A rear wheel housing liner (SBR {styrene butadiene rubber} resin material), which excel in sound absorption effect, is provided in the rear wheel housings. As a result, sand spattering sound, road noise, and water slashing sound have been reduced.

1 A front floor cover made of a recyclable bumper material with an additional 10% EPR (ethylene propylene rubber) is used. This material, which is pliable, yet ensures the proper rigidity, helps reduce the amount of sand spattering sound.





Reducing Wind Noise

1 The offset between the moldings and door glass or windshield glass molding has been minimized to reduce wind noise.(see A-A, B-B cross sections).

1 A parting sal that makes the gap flush between the radiator grille and the engine hood, is provided. This reduces the amount of wind noise that is generated along the parting area(see C-C cross sections).

1 A hood-to-front fender seal is provided to seal the area from the cowl side to the front edge of the front fender. This seal suppresss the amount of engine sound that leaks outside of the vehicle or enters the cabin (see D-D cross section).

1 A front fender side panel protector is provided to seal the gap between the front fender panel and the body. This protector limits the amount of road noise that enters from the wheels and reduces the amount of wind noise that is created by the inflow of air (see E-E cross section).

1 A parting seal that makes the gap flush between the front fender panel and the front door, as well as between the front door and the rear door, is provided. This reduces the amount of wind noise that is generated along the parting area (see E-E, F-F cross sections).

Door closure Sound Improvement





1 A sponge layer is provided to the front and rear door weatherstrips in order to reduce the rattling sound that is created when the door comes in contact with the door window frame as the door is being closed (see A-A cross section).

1 A hollow front door No.2 weatherstrip is provided at the rocker in order to reduce the sound that is created when the door is being closed (see B-B cross section).
