Using magnetic fields, Audi magnetic ride adjusts the firmness of the dampers to the current driving situation. It also gives the driver a choice of basic setting for either a more comfortable or a sportier drive.
Tiny magnetic particles are bound inside the basic oil in the dampers. When a magnetic field is applied, the magnetic particles are aligned against the direction of movement of the damper. As a result, the damping force of the damper is increased depending on the strength of the magnetic field. This allows the firmness of the dampers to be increased or decreased within a fraction of a second. A control unit computes the optimum damping force for the individual driving situation. It does so using information from the wheel travel sensors and communication with other systems such as the steering and ESP.
