History




History

With EDC I in the 1987 E32, BMW AG was the first European manufacturer to introduce a fully automatic electronically adjustable damper system. EDC I provided manual selection during driving between hard, sport and soft damping. Since the market launch, this 2-stage system has been continuously enhanced and evolved into EDC III, it has set the standard for adjustable damper systems in the 5 and 7 Series.

EDC III evaluates the status of the road surface, vehicle load, driving speed and driver's request to automatically activate one of three damper programs: soft, medium or hard The driver also has the option of selecting a comfort or sports program.

EDC-K is a further development of EDC III. The German abbreviation "K" stands for continuous damping force adjustment. The major change from EDC III is the damper valves and the activation control.




EDC-K operates with a continuously adjustable valve in each damper. The damping force is adjusted for individual piston speed. The damping force adapts continuously to the low frequency movement of the vehicle body, resulting in a significant increase in driving comfort. The driver has the option to select a comfort or sports setting by using the Controller in the Control Display menu.

The EDC-K system is an option offered under the Adaptive Ride Package.
