For enhanced safety, the front and rear seat shoulder belts of the Audi A8 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 Audi A8 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 A8 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 7 Series doesn’t offer front seat center airbags.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A8. But it costs extra on the 7 Series.
A passive infrared night vision system optional on the A8 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard and even aims one of the vehicle’s headlights in the direction of the person or object. The 7 Series doesn’t offer a night vision system.
Both the A8 and the 7 Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, rearview cameras, available blind spot warning systems and rear cross-path warning.
