For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC Coupe 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 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes GLC Coupe 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 doesn’t offer height-adjustable seat belts.

The GLC Coupe has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The X6 doesn’t offer front seat center airbags.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLC Coupe has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The X6 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the GLC Coupe and X6 have rear cross-traffic warning, but the GLC Coupe has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The X6’s Cross Traffic Warning doesn’t automatically brake.

Both the GLC Coupe and the X6 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, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.

The Mercedes GLC Coupe achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The X6 has not yet been fully evaluated by the IIHS for 2024.

A nine-speed automatic is standard on the Mercedes GLC Coupe, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the X6.

The GLC Coupe’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The X6 doesn’t offer drift compensation steering.

For better maneuverability, the GLC Coupe’s turning circle is 2.6 feet tighter than the X6’s (38.7 feet vs. 41.3 feet).

The Mercedes GLC Coupe may be more efficient, handle and accelerate better because it weighs about 700 to 1000 pounds less than the BMW X6.
