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 QX60 doesn’t offer a whiplash protection system.
The X7 has standard Post-Crash Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The QX60 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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X7. But it costs extra on the QX60.
When descending a steep, off-road slope, the X7’s standard Hill Descent Control allows you to creep down safely. The QX60 doesn’t offer Hill Descent Control.
Both the X7 and QX60 have rear cross-traffic warning, but the X7 has Cross Traffic Warning with Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX60’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the X7 and the QX60 have standard driver and passenger frontal airbags, front and rear 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
The BMW X7 weighs 710 to 1447 pounds more than the Infiniti QX60. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
