I am under the impression that Adaptive Drive includes electonically controlled shocks/swaybars that change characteristics based on conditions. It is not the same as the "226 Sport Suspension" included as part of M Sport Package on xDrive35i Sport Activity. I understand that 226 Sport Suspension consist of traditional stiffer springs/shocks package and maybe bigger anti roll bars that are static. Is it possible to spec a US X5d with the same stiffer shocks/springs that come on xDrive35d Sport Activity w/ M Sport Package?
