The X5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Nautilus doesn’t offer pre-crash pretensioners.
The X5 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 Nautilus doesn’t offer a whiplash protection system.
When descending a steep, off-road slope, the X5’s standard Hill Descent Control allows you to creep down safely. The Nautilus doesn’t offer Hill Descent Control.
Both the X5 and the Nautilus 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, around view monitors, rear cross-path warning, driver alert monitors and available all wheel drive.
The BMW X5 weighs 402 to 1224 pounds more than the Lincoln Nautilus. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The BMW X5 achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Nautilus has not yet been fully evaluated by the IIHS for 2024.
