Both the Mustang Mach-E and Niro EV have child safety locks to prevent children from opening the rear doors. The Mustang Mach-E has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Niro EV’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
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 Niro EV 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.
The Mustang Mach-E offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Niro EV doesn’t offer all-wheel drive.
The Mustang Mach-E has a standard 360-Degree Camera to allow the driver to see objects all around the vehicle on a screen. The Niro EV only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Mustang Mach-E and the Niro EV have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, 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 Ford Mustang Mach-E weighs 673 to 1241 pounds more than the Kia Niro EV. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
