The middle row seatbelts optional on the Expedition inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The QX80 doesn’t offer inflatable seatbelts.
The Expedition has standard Post-Impact Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The QX80 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
When descending a steep, off-road slope, the Expedition 4x4’s standard Hill Descent Control allows you to creep down safely. The QX80 doesn’t offer Hill Descent Control.
Both the Expedition and QX80 have rear cross-traffic warning, but the Expedition has Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX80’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Expedition and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, 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, around view monitors, rear cross-path warning, driver alert monitors and available all wheel drive.
