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 XC60 doesn’t offer a back seat reminder.
Both the Hummer EV SUV and the XC60 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, rearview cameras, rear cross-path warning and driver alert monitors.
The GMC Hummer EV SUV weighs 4148 to 4738 pounds more than the Volvo XC60. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
