In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Hummer EV SUV are reminded to check the back seat if they opened the rear door before starting out. The Model X doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Hummer EV SUV has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Model X doesn’t offer automatic braking for stationary objects directly to the rear.
The GMC Hummer EV SUV’s Surround Vision is equipped with washers for its front and rear cameras, ensuring crystal-clear visibility in any weather condition. Conversely, the Tesla Model X only offers a front camera washer, which may not provide the same level of all-weather performance.
The Hummer EV SUV has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model X doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Hummer EV SUV and the Model X 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, all wheel drive, 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 3425 to 3748 pounds more than the Tesla Model X. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
