Electronic Damper Control (EDC)

£ 390.00


Electronic damper control allows the driver to change the damper characteristics to two different settings, for an exceptionally smooth ride or increased driving dynamics. Along with the standard COMFORT setting, which provides a serene and pleasant driving experience, the SPORT setting is also available. When it is selected, the damper settings are firmer and the driving characteristics are more direct and dynamic. The settings are activated with the Driving Experience Control switch in the centre console.

Benefits at a glance:
• dynamic or comfortable driving at the push of a button
• optimal vibration characteristics, based on the load
• reduction in unpleasant pitching motions
