Both the Escalade IQ and Ariya have child safety locks to prevent children from opening the rear doors. The Escalade IQ has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Ariya’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Escalade IQ. But it costs extra on the Ariya.
A passive infrared night vision system standard on the Escalade IQ Premium helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Ariya doesn’t offer a night vision system.
The Cadillac Escalade IQ’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Nissan Ariya does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the Escalade IQ and Ariya have Rear Cross Traffic Alert, but the Escalade IQ has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Ariya’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Escalade IQ and the Ariya have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, front seat center airbag, 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, rearview cameras, rear cross-path warning and driver alert monitors.
The Cadillac Escalade IQ weighs 4063 to 4797 pounds more than the Nissan Ariya. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
