For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG S-Class 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 7 Series doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Mercedes AMG S-Class 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 7 Series doesn’t offer height-adjustable seat belts.
The rear seatbelts optional on the AMG S-Class 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 7 Series doesn’t offer inflatable seatbelts.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG S-Class. But it costs extra on the 7 Series.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The AMG S-Class has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The 7 Series doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the AMG S-Class and the 7 Series 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, 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.
