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 X2 doesn’t offer pretensioners for its rear seat belts.
The GLC Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The X2 doesn’t offer pre-crash pretensioners.
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 X2 doesn’t offer height-adjustable seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the GLC Coupe are reminded to check the back seat if they opened the rear door before starting out. The X2 doesn’t offer a back seat reminder.
The GLC Coupe has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The X2 doesn’t offer a whiplash protection system.
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 X2 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
The GLC Coupe’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The X2 doesn’t offer a driver alert monitor.
Both the GLC Coupe and the X2 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, rear cross-path warning and available lane departure warning systems.
The Mercedes GLC Coupe weighs 448 to 485 pounds more than the BMW X2. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
