I think the PIlot is based off of a car platfom, and that would definitely help with the drive and noise aspect.
Both the Pilot and Odyssey are based on the same Honda Global Light Truck platform. Technically, it is a car-based unibody platform and not a true truck frame platform. The Honda Ridgeline and Acura MDX also use this platform. I suspect the MDX probably gets even more soundproofing and may be the quietest of the bunch.
