2014 Mercedes-Benz GLK
midsize luxury SUV / 4-door SUV
Moderate overlap front: original test
Rating applies to 2011-15 models
Tested vehicle: 2011 Mercedes-Benz GLK 350 4-door 4wd
The Mercedes-Benz GLK was introduced in the 2010 model year. Beginning with 2011 models, a driver knee airbag was added to improve occupant protection in frontal crashes.

Action shot taken during the frontal offset crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well.
Smeared greasepaint indicates where the dummy's head hit the B-pillar during rebound. Head acceleration from this hit was low.
Although intrusion into the driver's space was minimal and the knee airbag deployed as intended, forces on the lower right leg were just high enough to indicate the possibility of injuries.

Tested vehicle: 2011 Mercedes-Benz GLK 350 4-door 4wd with standard front and rear head curtain airbags and standard front seat-mounted torso airbags
The Mercedes-Benz GLK was introduced in the 2010 model year. Beginning with 2011 models, the side torso airbags were modified to improve occupant protection in frontal crashes.
