New E-Class with active hood
50 Millimeters of additional safety
 
During a collision, the sensors report the impact to an electronic control unit that immediately activates the two electromagnets in the hinge elements. This
releases the locks for the pre-tensioned steel springs, raising the rear part of the hood by five centimeters.
Pedestrians are the most defenseless road users, and they frequently
suffer serious injuries when struck by a car or motorcycle. To address
this problem, Mercedes-Benz engineers have installed an innovative
protective system in the new E-Class: Known as the “active hood,” it
can reduce the risk of injury to pedestrians during accidents.

The hood does this by almost instantaneously rising 50 millimeters
during a collision, thus increasing the deformation space and reducing
the force of the impact. The crash-active system has three collision
sensors in the front bumper and cross-member as well as two actuators
with strong, pre-tensioned springs for the hood. Another advantage
of the system is that its activation can be reversed. If the hood is
unnecessarily raised as a result of a minor impact during a parking maneuver,
for instance, the driver can push it back to its original position
and thereby reset it. To satisfy legal requirements, the active hood is
available in the new E-Class in Europe an Japan.
