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 Premium 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, front seatbelt pretensioners, 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.
