Both the Hummer EV SUV and EQS SUV 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 EQS SUV’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 EQS SUV.
Both the Hummer EV SUV and the EQS SUV 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 and driver alert monitors.
The GMC Hummer EV SUV weighs 2573 to 2837 pounds more than the Mercedes EQS SUV. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
