X5 BMW X5 Adaptive Drive

[Human]

Hey guys, I need some help with ADAPTIVE DRIVE on the E70 X5.
BMW says in their ad - "At the touch of a button". Are there a button to engage Adaptive Drive when you have ordered your X5 with this Adaptive Drive option?

Secondly, does this system consists of Air type dampers? In other words what is all the changes on the suspension front & rear?

Last question, is it basically the same system that is used on the new 7 er a.k.a. Dynamic Damping Control?

Adaptive Drive:

On every curve, on every road surface: Adaptive Drive counteracts the forces that cause body roll. Your BMW handles with outstanding sporting agility, while also ensuring a very comfortable journey for you and your passengers. Body roll is practically eliminated, and winding roads can be enjoyed with a maximum of stability and safety.

The proven effectiveness of BMW's innovative chassis control systems, Dynamic Drive and Variable Damper Control (VDC) work closely together to deliver an outstandingly smooth ride and enhanced agility. Sensors in your BMW permanently monitor vehicle speed, steering-wheel position and the pitch and yaw forces acting on the chassis. Using this data, the system precisely adjusts the stabilisers and the dampers, changing their settings quickly and accurately. This coordinated interaction of dampers and stabilisers counteracts the forces that cause the body to roll or sway. Your BMW hugs the road, delivers neutral self-steering behaviour, outstanding agility and shorter braking distances.
Furthermore, Adaptive Drive adjusts the suspension settings to suit the character of the road surface. Each axle has its own independent motor that can adjust the dampers on each individual wheel. When the road surface under one side of the vehicle differs in character from that on the other side - such as when driving on roads with gravel shoulders - Adaptive Drive instantly adjusts the suspension settings of the wheels on one side to practically eliminate any perceptible unevenness in the road. In addition, you can choose between a more comfortable default setting for the suspension, or a more sporting setting.
Such high-speed calculations and responses demand a high-performance electronics system. Adaptive Drive utilises FlexRay, a high-speed data transfer system that networks sensors, control units and stabilisers.


Electronic Damper Control (EDC):

Electronic Damper Control (EDC) reduces variations in wheel load, ensures tyres have excellent traction and counteracts bodyshell movement regardless of the weight your automobile may be carrying - and regardless of the state of the road's surface. EDC can even help shorten braking distances, meaning you enjoy outstanding comfort along with the best in BMW on-road safety.

Sensitive sensors constantly monitor all factors influencing the vehicle's behaviour and occupants’ comfort, including road conditions, load changes and vehicle speed. In a fraction of a second, the signals are analysed by the EDC microprocessor and orders are sent to the actuators on the shock absorbers, which, with the help of magnetic valves, are variably adjusted to provide optimal suspension.
Thanks to Electronic Damper Control, the tendency for the nose to dip when braking is practically eliminated. The influence of potholes and unevenness on the road surface is reduced to minimum. Whether you're behind the wheel or relaxing in the rear of the cabin, EDC delivers a remarkably smooth and comfortable ride.

Thank you Klier! So, BMW does not use dampers like those of Mercedes called Airmatic anymore... I Guess this is a better system.

They had some sort of air suspension on the last 7er, but I'm not so sure about the new one Eni will though
I can't find anything about it in the BMW technology guide for the 7er....

btw, this one is also interesting and very good, and works closely together with Adaptive Drive in the X5:

Dynamic Drive:

Supreme agility, unwavering stability and unmatched comfort on bends: the active chassis control system Dynamic Drive minimises body roll and distributes it between both axles, ensuring a comfortable ride for all occupants.

Dynamic Drive uses active stabilisers on the front and rear axles to counteract the vehicle's tendency to roll in a corner. Working together with acceleration and position sensors, a management system and other components, such as a compensation tank for sound control, the system ensures supreme agility at all speeds, balanced reactions to load changes and remarkably precise steering.
The stabilisers continually adapt to suit the driving situation and the changes to the vehicle's self-steering behaviour. For example, when driving on the straight, Dynamic Drive reduces the pressure of the stabilisers, treating them individually, so allowing for a highly comfortable ride - a particular benefit for rear-seat passengers.
When cornering or making sudden changes of direction, a "sportier" setting will see the stabilisers increase the rigidity of the suspension relevant to the intensity of the lateral forces to prevent body roll. Roll distribution between the front and back axles also helps in difficult situations.
Dynamic Drive ensures that the vehicle literally hugs the road, under- or oversteering is reduced - resulting in enhanced safety, greater comfort and an impressively dynamic driving experience.

The e65, just as the F01, only use air suspension at the rear (and as an option, except on V8 with LWB).

It is surely more sporty than Airmatic (especially with the double-whishbones at the front for the F01), but in terms of comfort it's just not as good.

Airmatic with ABC is currently considered the best suspension sytem on earth, but it's clearly more adapted for comfort than for sport or cornering feel.
