The iX’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.
The iX’s standard pretensioning seatbelts also sense rear collisions and remove slack from the front seatbelts to help protect the occupants from whiplash and other injuries. The Aviator doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the iX. But it costs extra on the Aviator.
The BMW iX’s optional Surround View offers available integrated front and rear camera washers, ensuring clear, all-weather visibility without the need for manual cleaning. In contrast, the Lincoln Aviator lacks camera washers, requiring you to manually clean the cameras for optimal performance.
Both the iX 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 iX weighs 705 to 1104 pounds more than the Lincoln Aviator. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
