Compare the2024 Ford Mustang Mach-EVS 2025 GMC Hummer EV SUV

The Ford Mustang Mach-E has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Hummer EV SUV doesn’t offer knee airbags.

The Mustang Mach-E has standard front and rear seat side-impact airbags and head airbags, which act as a forgiving barrier between the passengers and the door. Combined with high-strength steel door beams this system increases protection from broadside collisions. The Hummer EV SUV doesn't offer rear-seat side-impact airbags, only ones for front seat occupants.

The Mustang Mach-E has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Hummer EV SUV doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the Mustang Mach-E and Hummer EV SUV have rear cross-traffic warning, but the Mustang Mach-E has Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Hummer EV SUV’s Rear Cross Traffic Alert doesn’t automatically brake.
