For enhanced safety, the front and second-row seat shoulder belts of the Mazda CX-90 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The VinFast VF 9 doesn’t offer pretensioners for its second-row seat belts.
For enhanced safety, the front seat shoulder belts of the Mazda CX-90 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 9 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 CX-90 are reminded to check the back seat if they opened the rear door before starting out. The VF 9 doesn’t offer a back seat reminder.
When descending a steep, off-road slope, the CX-90’s standard Hill Descent Control allows you to creep down safely. The VF 9 doesn’t offer Hill Descent Control.
Both the CX-90 and VF 9 have Rear Cross Traffic Alert, but the CX-90 Premium Plus/Turbo S has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The VF 9’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the CX-90 and the VF 9 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, 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 Mazda CX-90 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 VF 9 has not yet been evaluated by the IIHS for 2024.
