The 4-level air suspension is a sophisticated
electronically controlled air suspension
system on both axles.
The system permits variation of the ground
clearance by 66 mm and offers four defined
ground clearance levels between 142 and
208 mm.
Depending on driving conditions and
requirements, greater ground clearance or a
lower vehicle centre of gravity can be
selected.
The 4-level air suspension keeps the pre-set
vehicle level constant, irrespective of load
and weight distribution.
4-level air suspension
A high ground clearance, essential for uneven
terrain, gives the vehicle a correspondingly
high centre of gravity.
However, this is just as disadvantageous
when cornering as it is for driving stability at
higher speeds.
Additionally, this is increases air resistance,
which significantly affects fuel consumption.
On the other hand, the reduced spring travel
and the harder set-up version of a "road-
running gear", result in inadequate off-road
driving comfort.
