So I’m driving a S80 D5 since 3mon. And I thought…you can put the summer tires on it and everything will be fine. Nix is good ..at 140 KM/H he blows…new exhaust holder…no change. From 160 KM/H the soundscape is as strong as I would have never expected from a “premium” car. Before E class W211 …leise slipping along up to 200 speed. Then CLK Cabrio ..at tempo 160 about exactly as loud with a closed fabric roof as the S80. Is the box generally so loaded with wind and rumbling noise, or did I have only bad luck? Unfortunately my friend did not have a comparison vehicle to test. If so, Volvo is still light years away from the premium. The Honda from my wife is quieter by length of speed. Conclusion: 3 hours. Autobahn over 150 km/H is a goal tour.
