Important: Frontal crash test ratings should be compared only among vehicles of similar weight.
The Mercedes M class was redesigned for the 2012 model year. Beginning with 2014 models built after August 2013, reinforcements were added to the door sills to improve occupant protection in small overlap frontal crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door). The tested vehicle was built after the door sills were strengthened.
The driver space was maintained reasonably well, with maximum intrusion of the lower interior of 18 cm at the footrest, and the instrument panel intruded 9 cm.
Measures from the dummy indicate that injuries to the left lower leg would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.
Restraints and dummy kinematics
The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. The side curtain airbag deployed and had sufficient forward coverage to protect the head from contact with side structure and outside objects.
