For enhanced safety, the front and second-row seat shoulder belts of the Infiniti QX80 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 X7 doesn’t offer pretensioners for its second-row seat belts.
For enhanced safety, the front and middle seat shoulder belts of the Infiniti QX80 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 X7 doesn’t offer height-adjustable front seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the QX80 are reminded to check the back seat if they opened the rear door before starting out. The X7 doesn’t offer a back seat reminder.
The QX80 has standard Active Head Restraints (AHR), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the AHR system moves the headrests forward to prevent neck and spine injuries. The X7 doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The QX80 has standard Backup Collision Intervention that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The X7 doesn’t offer backup collision prevention brakes.
Both the QX80 and the X7 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available all wheel drive.
