A quiet car in terms of tire and wind noise, the Volvo S80 did exhibit a number of rattles and audible vibrations over a week of driving over various road surfaces, most of which sounded as though it emanated from the rear of the vehicle. This was most evident either on rougher than normal asphalt or when the S80 was high in the rev range. With an almost $60,000 price tag attached to the bumper, that's a little disappointing.
