For enhanced safety, the front seat shoulder belts of the Ford Mustang Mach-E are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Fiat 500e doesn’t offer height-adjustable seat belts.
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 Mustang Mach-E are reminded to check the back seat if they opened the rear door before starting out. The 500e doesn’t offer a back seat reminder.
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 500e 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.
Over 200 people are killed each year when backed over by motor vehicles. The Mustang Mach-E has a standard Reverse Brake Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 500e doesn’t offer backup collision prevention brakes.
The Mustang Mach-E offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 500e 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 500e 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.
The Mustang Mach-E 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 500e’s blind spot costs extra.
To help make backing out of a parking space safer, the Mustang Mach-E has standard Cross Traffic Alert and Cross Traffic Braking automatically engages the brakes to help avoid a collision. Fiat charges extra for Rear Cross Path Detection on the 500e and the 500e’s Rear Cross Path Detection does not include automatic braking.
Both the Mustang Mach-E and the 500e have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.
The Ford Mustang Mach-E weighs 1442 to 2010 pounds more than the Fiat 500e. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
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 2024 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 500e has not yet been evaluated by the IIHS for 2024.
