For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG GLC have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW X6 M doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes AMG GLC are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X6 M doesn’t offer height-adjustable seat belts.

To help make backing safer, the AMG GLC’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The X6 M doesn’t offer a cross-path warning system.

Both the AMG GLC and the X6 M have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, available lane departure warning systems and around view monitors.
