For enhanced safety, the front and second-row seat shoulder belts of the Mercedes AMG GLE 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 its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Mercedes AMG GLE 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.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The AMG GLE has Car-to-X, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The X6 M doesn’t offer a system that can receive automated systems from other vehicles.
Both the AMG GLE and X6 M have rear cross-traffic warning, but the AMG GLE has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The X6 M’s Cross Traffic Warning doesn’t automatically brake.
Both the AMG GLE 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, around view monitors, rear cross-path warning, driver alert monitors and available lane departure warning systems.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the AMG GLE its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 67 vehicles tested by the IIHS. The X6 M has not been tested, yet.
