In the presentation, we learned about engine compartment, interior trim, and door panel acoustic absorbers; acoustic laminated
windshield and laminated front side
glass; and a liquid - apply sound deadener, and how they all
contributed to make the Envision one of the quietest rides on the road.
Details like a new polycarbonate
windshield (some 14 lbs lighter than
glass), lower - weight batteries (6 lbs lighter) and a combination of lighter body panels all
contribute to the weight savings.
