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 Ariya doesn’t offer pre-crash pretensioners.
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. Nissan doesn’t offer the convenience and security of a built-in child booster seat in the Ariya. 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 Ariya doesn’t offer a whiplash protection system.
The EX90 has standard Post-impact braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Ariya doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the EX90. But it costs extra on the Ariya.
Both the EX90 and Ariya 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 Ariya’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the EX90 and the Ariya 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, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Volvo EX90 weighs 1155 to 1889 pounds more than the Nissan Ariya. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
