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 Vinfast VF 8 doesn’t offer height-adjustable seat belts.
Both the Mustang Mach-E and VF 8 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 VF 8’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.
Both the Mustang Mach-E and VF 8 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 VF 8’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Mustang Mach-E and the VF 8 have standard driver and passenger frontal airbags, front and rear 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, 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.
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 175 vehicles tested by the IIHS. The VF 8 has not been tested, yet.
