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 Lyriq 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. Cadillac doesn’t offer the convenience and security of a built-in child booster seat in the Lyriq. 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 Lyriq doesn’t offer front seat center airbags.
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 Lyriq 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 Lyriq.
The EX90’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Lyriq doesn’t offer a driver alert monitor.
Both the EX90 and the Lyriq 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.
The Volvo EX90 weighs 402 to 655 pounds more than the Cadillac Lyriq. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
