Two lidar laser scanners integrated into the headlights scan the road ahead of the vehicle and detect irregularities.

Using PRE-SCAN suspension, the car not only reacts highly sensitively to uneven patches of road surface, but also acts in an anticipatory manner.

PRE-SCAN uses two laser sensors in the headlamps as “eyes” that produce a precise picture of the road's condition.

From this data, the control unit computes the´parameters for the active suspension settings in order to provide the highest level of comfort.

PRE-SCAN was an early prototype of Magic Body Control (with Road Surface Scan), that was introduced in 2013 on the Mercedes-Benz S-Class (W222).
