For enhanced safety, the front and second-row seat shoulder belts of the Mercedes AMG GLB 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 AMG GLB’s optional 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 AMG GLB 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.
The AMG GLB offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The X2 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG GLB. But it costs extra on the X2.
The AMG GLB offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The X2 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The AMG GLB has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the X2’s blind spot costs extra.
The AMG GLB’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 AMG GLB 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and available lane departure warning systems.
