Adaptive Drive was part of the Sport Package for my 2008 E70 4.8i. I think that it was not included in Sport Package in later years.

I really like the "active roll stabilization". It just eliminates body roll in corners. My son had to use my X5 for his Street Survival driving school last year and I wished I could have turned it off. Didn't matter how much he threw it around the track, it didn't roll or lean at all.
