The EX90’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The VF 8 doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Volvo EX90 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.
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 EX90 are reminded to check the back seat when a sensor determines the back seat is occupied. The VF 8 doesn’t offer a back seat reminder.
The Volvo EX90 (except 6-Passenger) offers an optional built in child booster seat. It’s more crash worthy than an added child seat because of its direct attachment to the seat. VinFast doesn’t offer the convenience and security of a built-in child booster seat in the VF 8. Their owners must carry a heavy booster seat in and out of the vehicle; EX90 owners can just fold their built-in child seat up or down.
The EX90 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The VF 8 doesn’t offer a whiplash protection system.
Both the EX90 and VF 8 have rear cross-traffic warning, but the EX90 has Braking Intervention (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 EX90 and the VF 8 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, front seat center airbag, 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, post-collision automatic braking systems, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
The Volvo EX90 weighs 657 to 800 pounds more than the VinFast VF 8. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
