The X7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Aviator doesn’t offer pre-crash pretensioners.
For enhanced safety, the middle seat shoulder belts of the BMW X7 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 Lincoln Aviator doesn’t offer height-adjustable middle 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 X7 are reminded to check the back seat if they opened the rear door before starting out. The Aviator doesn’t offer a back seat reminder.
The X7 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Aviator doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X7. But it costs extra on the Aviator.
Both the X7 and the Aviator 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, driver alert monitors and available around view monitors.
The BMW X7 weighs 590 to 1241 pounds more than the Lincoln Aviator. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
