For enhanced safety, the front seat shoulder belts of the Mercedes EQS 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 i7 doesn’t offer height-adjustable seat belts.
The rear seatbelts optional on the EQS inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The i7 doesn’t offer inflatable seatbelts.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The EQS has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The i7 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the EQS and the i7 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, 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.
