In this video, race car driver Scott Pruett and BMW Product & Technology Communications Manager Matt Russell explain the BMW M Electronic Damper Control (EDC) system and how the Comfort, Sport and Sport+ suspension settings make a difference in the F10 M5 and F12/F13 M6.
Although the M5 and M6 use an M tuned version of the BMW EDC, here is a general summary of EDC technology
Electronic Damper Control (EDC) automatically or manually adjusts each damper to suit the driving conditions meaning you enjoy outstanding comfort along with the best in BMW on-road safety. EDC reduces variations in wheel load, ensures tyres have excellent traction and counteracts bodyshell movement regardless of the weight your automobile may be carrying or the state of the road's surface.
Sensors constantly monitor all factors influencing the vehicle's behaviour and occupants' comfort, in order to precisely adjust the damper control. In a fraction of a second, the signals are analysed by the EDC microprocessor and orders are sent to the actuators on the shock absorbers, which, with the help of magnetic valves, are variably adjusted to provide optimal suspension. Thanks to Electronic Damper Control, the tendency for the nose to dip when braking is practically eliminated. The influence of potholes and unevenness on the road surface is reduced to minimum.
In addition to increased driving comfort and improved roll characteristics on the tyres, EDC also contributes to vehicle stability and safety. By reducing the nose's tendency to dip when braking and improving the tyre traction, EDC shortens the braking distance when braking heavily. The damper adjustment means that even when braking with ABS the vehicle chassis remains upright on the road and all four wheels have the largest possible contact to the surface.
The Driving Experience Control switch with ECO PRO lets the driver choose between various programs (like COMFORT, NORMAL, SPORT or SPORT+) and adjust the suspension to suit his individual needs.
