It's great that a car can go around the Nürburgring in no time but does not mean the car will be easy to drive or comfortable to live with. I'm sure BMW tests all their pre-production cars at the track but some of the cars that come out are frankly, a bit oddly tuned suspension-wise. A modern BMW with RFT has subpar ride quality and the ride in the 2004 X3 is so hard on some roads that they had to go back to the drawing board the very next year.
