For enhanced safety, the front seat shoulder belts of the Toyota bZ4X 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.
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 bZ4X are reminded to check the back seat if they opened the rear door before starting out. The VF 8 doesn’t offer a back seat reminder.
Both the bZ4X and VF 8 have rear cross-traffic warning, but the bZ4X has Parking Support Brake (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 bZ4X and the VF 8 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear 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.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Toyota bZ4X is safer than the VinFast VF 8:

The Toyota bZ4X 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 VF 8 has not yet been evaluated by the IIHS for 2025.
