Small overlap front: driver-side

Rating applies to 2016-19 models

Tested vehicle: 2017 Mercedes-Benz GLC 300 4-door 4wd

The Mercedes-Benz GLC was introduced in the 2016 model year as a replacement for the Mercedes-Benz GLK.

Driver restraints and dummy kinematics
The dummy’s head contacted the frontal airbag but rolled to the left because the seat belt allowed excessive forward excursion of the head and torso. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects.

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 well.

The dummy’s head contacted the frontal airbag but rolled around the left side, allowing the head to move toward the gap in coverage between the frontal and side curtain airbags.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

How the driver-side small overlap front test is conducted

Small overlap front: passenger-side

Rating applies to 2016-19 models

Tested vehicle: 2018 Mercedes-Benz GLC 300 4-door 4wd

The Mercedes-Benz GLC was introduced in the 2016 model year as a replacement for the Mercedes-Benz GLK. Two passenger-side small overlap frontal tests of a 2018 model GLC were conducted, one by the Institute and the other by Mercedes-Benz as part of frontal crash test verification. Ratings are based on both tests.

Action shot taken during the Institute's passenger-side small overlap frontal crash test.

The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger's survival space was maintained well (Institute test car shown).

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 (Institute test shown).

The passenger's space was maintained well in both tests, but forces on the right lower leg were just high enough to indicate the possibility of injuries in the Institute's test. In the test conducted by Mercedes-Benz, injury risk to both legs and feet was low.

The low beams created some glare.

High beams
On the straightaway, visibility was fair on the right side of the road and inadequate on the left side. On curves, visibility was good in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on the gradual left curve.
