For enhanced safety, the front seat shoulder belts of the Porsche Cayenne 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.
When descending a steep, off-road slope, the Cayenne’s standard Porsche Hill Control allows you to creep down safely. The VF 9 doesn’t offer Porsche Hill Control.
A passive infrared night vision system optional on the Cayenne helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The VF 9 doesn’t offer a night vision system.
Both the Cayenne and VF 9 have Rear Cross Traffic Alert, but the Cayenne has automatic 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 Cayenne and the VF 9 have standard driver and passenger frontal airbags, front and rear 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
