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. Frontal ratings are assigned by the Institute based on a test conducted by Mercedes as part of frontal crash test verification.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

Dummy movement was well controlled. After the dummy moved forward into the airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury.

Side crash test ratings can be compared across vehicle categories.

The Mercedes M class was redesigned for the 2012 model year. Beginning with 2014 models, side torso airbags became optional for rear seat occupants (they were standard in 2012-13 models). Side ratings are assigned by the Institute based on two tests conducted by Mercedes-Benz as part of side crash test verification.

The first test was conducted on a 2012 model ML 550 V8 (including the standard rear side torso airbags) and the second test on a 2014 model ML 350 Bluetec diesel V6 without the optional rear side torso airbags. The ratings for these vehicles are combined because the presence or lack of rear side torso airbags made little difference for rear occupant protection in the tests. (Rear occupants still receive the benefit of the standard side curtain airbags.) This is because for a large vehicle with a long wheelbase (115 inches in this case), the intruding barrier impacts the vehicle relatively far from the rear seat.

The vehicle specifications shown below are based on the 2014 model. (The tested 2012 model is over 300 pounds lighter but obtains poorer gas mileage. Wheelbase, length, and width are identical.)

.

Injury measures

Driver — In both tests, measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Passenger — In both tests, measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — In both tests, the dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Passenger — In both tests, the dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
