Both the Mustang Mach-E and Clarity Fuel Cell 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 Clarity Fuel Cell’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 Clarity Fuel Cell 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 use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Clarity Fuel Cell 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 Clarity Fuel Cell doesn’t offer all-wheel drive.
The Mustang Mach-E offers an optional 360-Degree Camera to allow the driver to see objects all around the vehicle on a screen. The Clarity Fuel Cell only offers a rear monitor.
To help make backing out of a parking space safer, the Mustang Mach-E’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Clarity Fuel Cell doesn’t offer a cross-path warning system.
The Mustang Mach-E’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Clarity Fuel Cell doesn’t offer a driver alert monitor.
Both the Mustang Mach-E and the Clarity Fuel Cell 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 and rearview cameras.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Mustang Mach-E the rating of “Top Safety Pick” for 2022, a rating granted to only 137 vehicles tested by the IIHS. The Clarity Fuel Cell has not been tested, yet.
