BMW has done an outstanding job with this redesign. The old and new X5 both perform well, but the new X5 adds REFINEMENT to the equation. Wind/road noise are hugely reduced. Interior quality is greatly improved. The sport package with active suspension hugs the road, yet gives very smooth ride quality with minimal lean in corners. Contour seats are excellent, although the active "massage" seats are a little weird (like having a python slowly undulate under the seat cushion). No squeaks, rattles. No defects. I tire of the computer-challenged press who constantly complain because they can't learn all iDrive features in a 10-minute test drive. I love the control it gives over vehicle functions.
Smooth/quiet on highway with excellent handling. BMW's upgraded contour seats are the best seats in any car, period. Stiff chassis feels ultra solid. Heads up display with nav system. Well-placed cup holders, storage bins. Upgraded stereo, bluetooth phone.
Active steering is a travesty for BMWs already perfect steering (avoid this unnecessary expense). Heavy vehicle needs more HP or less weight. Buttons that switch on interior lights should be illuminated at night. Bigger gas tank. Parking distance control should be separate option from rear camera.
