I'm very upset because then why out the comfort, sport and sport plus?!! It's useless!!!! Why do I need a steering wheel that becomes rigid when the suspension is all soft, it's not like I can drive it as I want because you feel all the movement!! Side to side! |

42pilot, look at your window sticker. If you don't have a line item "Adaptive M Suspension" for $900 then it's not there.. See example screenshot (I drove this X5 at Ultimate Drive Event)

If you have the adaptive M suspension, but not the ARS, you can stiffen (sport) or soften (comfort) your suspension, but the system won't actively attempt to prevent body roll. However, you will get less in sport because its not bouncy like comfort, but with ARS, its Considerably less. Lets take a look at everything (and why you want it ) BMW has some nice videos about adaptive drive for the E70. AD is electronic damper control + active roll stabilization. The interesting thing is that the Adaptive M suspension is only the electronic damper control part of that equation. Here is a video that shows what EDC does. In this video, ARS is called 'dynamic drive': Active roll stabilization controls body roll: Here's an interesting technical-like video on the forces at play: The dynamic handling package gives you dynamic performance control and ARS (and I think some have said here that if you don't order the MSport package, it also has the EDC). Here is a long-winded, yet very informative description of DPC from Wikipedia: "BMW's Dynamic Performance Control torque-vectoring system works in unison with xDrive all-wheel drive and Dynamic Stability Control. DPC is a drivetrain and chassis control system that works to regulate traction and especially correct over- and understeer by actively spreading out drive forces across the rear axle. Torque is split not only between the front and rear wheels (xDrive) but also from side to side at the rear for improved agility and added stability (through the DPC rear axle). DPC works at all speeds and normal driving, not just during hard cornering, in order to steer the car. DPC also interfaces with DSC to initially try to correct the vehicle's path using torque vectoring which results in smooth turns, whereas DSC by itself would only reduce engine power and apply the brakes to steer the vehicle. The DPC differential features clutch packs on both output sides that are actuated by an electric motor. The clutch pack activates a planetary gearset which causes one wheel to be overdriven. A conventional control system will use the brakes to reduce the speed of the faster-moving wheel (which is the one with less traction) and reduce engine power. This leads to increased brake wear and slower than optimal progress. In contrast, the DPC system speeds up the slower moving wheel (the one with the most traction) in order to maintain stability when needed. For example, while turning, the outer wheel is overdriven to provide greater acceleration, using the traction advantage through the dynamic loading of the outboard wheel in cornering. Meanwhile, in an oversteer situation, the inner wheel is overdriven to regain traction balance. The first application of DPC was introduced on the BMW X6, which began production in 2008 as a 2009 model, where it is a standard equipment. A test found that 'the X6 feels hundreds of pounds lighter on its feet than an X5 [without DPC]' due to the benefit of DPC even though both vehicles have similar chassis dimensions. The BMW X5 M high performance variant also has standard DPC." Ohhh...DPC sounds good, eh? It is. Slap EDC, ARS, and DPC on that puppy and you have the ultimate giant driving machine. |

Here's the skinny: 4UB 3rd row seat + rear axle air suspension 4UB will add 4NC to the order 4UB cannot be ordered with 300 4UB cannon be ordered with LCMY, ZDI or ZMD Exclusions: 300 Space-saver spare LCMY Mocha Dakota Leather ZDI Ivory White Interior Design Package ZMD Mocha Interior Design Package Adaptive M suspension is 2VS and Dynamic Handling Package is ZDH (ARS+DPC). Neither one of those is excluded. If they're excluding it, its a secret that isn't on the ordering sheet. I had adaptive drive on an E70 with 3rd row. So that was basically Adaptive M + active roll stabalization (1/2 ZDH). If they don't let you get DPC (the other 1/2 ZDH), you would think that you at least could get 2VS. I don't think that you can get a 3rd row in an X5M because they don't want to have to tune the car twice. They probably wouldn't sell a lot of 3rd rows in X5Ms anyway. |

Just wanted to clarify the bit about adaptive m: Adaptive M suspension is 2VF and requires M-Sport. Dynamic Handling Package ZDH also includes 2VM, a softer and less stiff version of 2VF. M-Sport cannot have 2VM, it can only be standard suspension ZSU or Adaptive 2VF. So ZDH on a non msport gets the more comfortable 2VM suspension, but on an M-Sport it will be the stiffer/sportier 2VF. |
