A lowered floor vehicle typically has more road noise because the vehicle is so much closer to the ground. BraunAbility takes special care to reduce road noise by offering an exclusive feature called Quiet Drive. This noise reduction technology results in up to a 25% overall reduction in wheelchair vehicle noise. This reduction is achieved by noise blocking weather seals, reengineered exhaust to minimize noise and vibration, as well as special noise absorbing materials in the interior of the vehicle.
