For enhanced safety, the front seat shoulder belts of the GMC Hummer EV SUV are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW iX doesn’t offer height-adjustable seat belts.
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 iX doesn’t offer a back seat reminder.
Both the Hummer EV SUV and the iX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, rearview cameras, rear cross-path warning and driver alert monitors.
The GMC Hummer EV SUV weighs 3082 to 3230 pounds more than the BMW iX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
