The peace and tranquility of the GX460’s interior set an entirely new benchmark for luxury SUVs. Numerous measures were taken to help reduce noise and vibration to a minimum, beginning with the advanced ‘Body on Frame’ construction which incorporates sophisticated dampers to absorb vibration. The engine mounts also absorb a significant amount of vibration. Because SUV engines can also create substantial noise, Lexus engineers focused on minimizing friction and enhancing the rotational balance of the engine, as well as using an insulated engine cover to further mute extraneous sound. Noise ingress to the cabin is further dampened by the widespread use of special sound-insulating materials, including high-specification laminated glass.
