Vertical dynamics management
The E70 can be equipped with the optional extra 2VA "Adaptive Drive". This optional extra consists of 2 systems:
vertical dynamics management (VDM) and active roll stabilization (ARS: sales designation Dynamic Drive). This service information describes the vertical dynamics management.
Vertical dynamics management offers the following advantages:
- greater on-road comfort
- greater vehicle agility
- improved self-steering characteristics and load-change characteristics

EDC means: Electronic Damper Control
The vertical dynamics management (VDM) is an enhancement of the continuous Electronic Damper Control (EDC-K) from the E65. VDM is composed of a central control module and 4 intelligent damper satellites firmly connected to the shock absorbers.
As data line, the data bus FlexRay has been implemented for the first time.
