For enhanced safety, the front and second-row seat shoulder belts of the Mercedes EQS SUV 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 iX doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Mercedes EQS SUV 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 iX doesn’t offer height-adjustable seat belts.
The EQS SUV 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 iX 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 EQS SUV has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The iX doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the EQS SUV and the iX have standard driver and passenger frontal airbags, front and rear 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Mercedes EQS SUV weighs 456 to 1091 pounds more than the BMW iX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
