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 Bolt doesn’t offer backup collision prevention brakes.
The Hummer EV SUV offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Bolt doesn’t offer all-wheel drive.
The Hummer EV SUV has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Bolt’s blind spot costs extra.
