The electrical active stabilizers (EARS) had their series introduction in the
G12. The stabilizers are
available to the customer only as optional equipment in conjunction with further
suspension control
systems (see Highlights chapter). The system has been adopted in full in the G30
with the exception of
the preview function.
The preview function, which was implemented on the G12 using the stereo camera,
is not used on the
G30. For this reason, the name of the optional equipment has been changed from
"Executive Drive
Pro" on the G12 to "Adaptive Drive" or " Dynamic Handling Package" on the G30.
