Both the Mustang Mach-E and Leaf 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 Leaf’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 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Leaf doesn’t offer all-wheel drive.
Both the Mustang Mach-E and Leaf 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 Leaf’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Mustang Mach-E and the Leaf have standard driver and passenger frontal airbags, front and rear 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The Ford Mustang Mach-E (built after August 2024) has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Leaf has not yet been evaluated by the IIHS for 2025.
