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 CX-90 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. Mazda doesn’t offer the convenience and security of a built-in child booster seat in the CX-90. 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 front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The CX-90 doesn’t offer front seat center airbags.
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 CX-90 doesn’t offer a whiplash protection system.
To help make backing out of a parking space safer, the EX90 has standard Cross Traffic Alert with Braking Intervention, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the CX-90 Premium Plus/Turbo S offers Rear Cross Traffic Braking.
Both the EX90 and the CX-90 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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 969 to 1503 pounds more than the Mazda CX-90. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
