Small overlap front: driver-side

Rating applies to 2014-15 models built after August 2013

Tested vehicle: 2014 Mercedes-Benz ML 350 4-door 4wd

The Mercedes-Benz M-Class was redesigned for the 2012 model year and renamed the GLE-Class beginning with the 2016 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. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.) The tested 2014 model M-Class was built after the door sills were strengthened.

Action shot taken during the driver-side small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained reasonably well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

Intrusion of the footrest and instrument panel was sufficient to contribute to a moderate risk of injury to the left lower leg, even though the knee airbag inflated.

How the driver-side small overlap front test is conducted

Small overlap front: passenger-side

Tested vehicle: 2018 Mercedes-Benz GLE 350 4-door 4wd

The Mercedes-Benz M-Class was redesigned for the 2012 model year and renamed the GLE-Class beginning with the 2016 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. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

Passenger-side small overlap frontal ratings are assigned by the Institute based on a test conducted on a 2018 model GLE-Class by Mercedes-Benz as part of frontal crash test verification.

How the passenger-side small overlap front test is conducted

Moderate overlap front

Rating applies to 2012-15 models

Tested vehicle: 2012 Mercedes-Benz ML 550 4-door 4wd

The Mercedes-Benz M-Class was redesigned for the 2012 model year and renamed the GLE-Class beginning with the 2016 model year. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted on a 2012 model M-Class by Mercedes-Benz as part of frontal crash test verification.

How the moderate overlap front test is conducted

Side

Rating applies to 2012-15 models

Tested vehicle: 2014 Mercedes-Benz ML 350 Bluetec 4-door 4wd with standard front and rear head curtain airbags and standard front seat-mounted torso airbags

The Mercedes-Benz M-Class was redesigned for the 2012 model year and renamed the GLE-Class beginning with 2016 models.

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.
