"Ride Quality The ride quality is extremely smooth when compared to conventional springs as compressed air is used to absorb irregularites on the road. This is perfect for providing a soft and comfortable ride for passengers but by adjusting the air pressure the suspension can be stiffened for a sport setting."

The ride quality with the air suspension is much better than that without.
The X5 system works only on the rear suspension, and is made to level the car under heavy load...The system is not built into the shock absorber. You can not adjust the the airpressure for a smother ride, and it does not interact with the front suspension. Which means that the airpressure / spring rate must be the same as a conventional X5 without self levelling..I have driven both, and have not noticed any difference at all..

You can compare the BMW EDS system with a fully airsuspension equipped car.( in wider terms)..It means that the hole system works together, and you can soften/ harden the suspension with a push on a button...
