It actually changes stiffness DURING dynamic maneuvers- take speed bumps, the system will see the front compress and will soften the rears... during a turn it will stiffen the sway bars AS the pitch/yaw sensors are telling the controller "the body is trying to roll'...and then, when the maneuver is over, it will soften to get ready for the next movement...


I have a very (very) stiff system on the 996TT, two way dampers, all that- and it is stiff ALL the time. AD is a system that is compliant when flat, but stiffens in ways that counter the motion.


I dont know enough about the EDC system and how if differs from the AD


My take away is that AD isnt just 'variable sway and strut settings'- but rather dynamically variable is the body is moving.


I had driven one of the first such systems on the Infiniti Q45 in 1992. Compared to that, the BMW system is much more refined- almost undetectable when it intervenes. Which is IMO they were going for.
