What is Nivomat Self-levelling anyway?

Nivomat counters the negative effects of loads, including towing a trailer, by helping maintain the vehicle’s optimal ride hight. The system replaces conventional shock absorbers on the rear axle, taking the energy derived from the relative movement between the wheels and vehicle body to energize the system, which maintains level position. Since Nivomat maintains ride height for every load, it prevents the vehicle’s center of gravity from shifting, which helps keep the vehicle balanced and safe in all conditions.
"Constant heavy or changing loads, along with the unique dynamics of towing a trailer, place great demands on the vehicle and the driver," says Dr. Stefan Sommer, Senior Vice President of the Suspension Components strategic business unit of ZF Sachs AG. “Nivomat ensures consistent performance and a more balanced driving feel, regardless of the load or driving conditions."
