For enhanced safety, the front and rear seat shoulder belts of the Cadillac Lyriq 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 Cadillac Lyriq 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 Lyriq 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.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Cadillac Lyriq achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The VinFast VF 9 has not been tested.
Both the Lyriq and VF 9 have Rear Cross Traffic Alert, but the Lyriq 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 Lyriq 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and available driver alert monitors.
