Whether your are driving slowly through narrow alleys, backing into small parking spaces or taking sharp corners quickly, ZF's AKC (Active Kinematics Control) active rear axle steering system improves safety, dynamics and comfort in almost any driving situation. AKC is available in two versions: as central actuator or dual actuator. With dual actuators, one actuator each is positioned on the left and right rear wheel. Ideal for sports cars as this solution saves valuable installation space in the center of the rear axle. After all, this is often where engine, tank or other components are placed.
The central actuator variant with a single but larger and centrally positioned actuator is ideal for sedans, pick-ups or SUVs. Regardless of whether a central or dual actuator is used, both change the rear wheel toe angle and thus strongly influence the steering function despite a comparatively small travel distance. Thus, AKC not only increases maneuverability but also improves stability at high speeds. The latter leads to a plus in safety, especially during unexpected evasive maneuvers.
