Both the Hummer EV SUV and Ariya have child safety locks to prevent children from opening the rear doors. The Hummer EV SUV 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 Hummer EV SUV. But it costs extra on the Ariya.
The GMC Hummer EV SUV’s Surround Vision has integrated front and rear camera washers, ensuring clear, all-weather visibility without the need for manual cleaning. In contrast, the Nissan Ariya lacks camera washers, requiring you to manually clean the cameras for optimal performance.
Both the Hummer EV SUV and Ariya have Rear Cross Traffic Alert, but the Hummer EV SUV 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 Hummer EV SUV and the Ariya 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, rearview cameras, rear cross-path warning and driver alert monitors.
The GMC Hummer EV SUV weighs 3616 to 4577 pounds more than the Nissan Ariya. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
