The XLR's featured adaptive suspension with magneto-rheological shock absorber fluid for enhanced ride control. The system uses four wheel-to-body displacement sensors to measure wheel motion over the road surface and responds by adjusting the shock damping almost instantly. The shock absorbers are filled with a fluid that contains suspended iron particles that respond to magnetic signals. The system responds by constantly monitoring motion and changing the damping forces at all four corners of the vehicle — to modulate body motion during aggressive maneuvers or on uneven road surfaces.
