For enhanced safety, the front seat shoulder belts of the Kia EV9 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 EV9 and VF 8 have child safety locks to prevent children from opening the rear doors. The EV9 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.
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 EV9 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 EV9 and VF 8 have rear cross-traffic warning, but the EV9 has Rear Cross-Traffic Collision-Avoidance Assist (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 EV9 and the VF 8 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, front seat center airbag, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, 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 Kia EV9 (Built after January 2024) achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The VF 8 has not yet been evaluated by the IIHS for 2024.
