The **DiSus-Z suspension** on the Yangwang U7 replaces the hydraulic components of conventional dampers with **linear electric motors**. The motors generate suspension force directly through linear movement, performing the damping function while also enabling active control of suspension displacement. 

Multiple sensors, including cameras and millimetre-wave radar, continuously detect road conditions. The vehicle’s computing centre processes this information and commands the linear motors to adjust suspension forces. According to the article, the system has a **10 ms response time**, allowing rapid suspension adjustment even at high vehicle speeds. 

Because the actuators can actively generate movement, DiSus-Z can also control the vehicle’s body position. Functions described include **negative roll during cornering**, pitch suppression during hard acceleration and braking, controlled suspension movement during jumps, dynamic levelling when mounting a kerb, single-side lifting and evasive manoeuvre assistance. 

A further function uses the electric motors for **regenerative suspension energy recovery**. Suspension movement can drive the motors as generators, converting part of the vehicle’s vertical kinetic energy into electrical energy.
