For enhanced safety, the front and middle seat shoulder belts of the Volvo XC90 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 Buick Enclave doesn’t offer pretensioners for the middle seat belts.
The XC90’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Enclave doesn’t offer pre-crash pretensioners.
For enhanced safety, the front and middle seat shoulder belts of the Volvo XC90 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 Buick Enclave doesn’t offer height-adjustable front seat belts.
Both the XC90 and Enclave have child safety locks to prevent children from opening the rear doors. The XC90 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Enclave’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Volvo XC90 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. Buick doesn’t offer the convenience and security of a built-in child booster seat in the Enclave. Their owners must carry a heavy booster seat in and out of the vehicle; XC90 owners can just fold their built-in child seat up or down.
The Volvo XC90 has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Enclave doesn’t offer knee airbags.
Using vehicle speed sensors and seat sensors, smart airbags in the XC90 deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The XC90’s side airbags will shut off if a child is leaning against the door. The Enclave’s airbags don’t have smart features and will always deploy full force.
The XC90 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. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Enclave doesn’t offer a whiplash protection system.
The XC90 has standard Automatic Braking After Collision, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Enclave 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.
The XC90 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Enclave doesn’t offer all-wheel drive.
The XC90’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 Enclave doesn’t offer a driver alert monitor.
Both the XC90 and the Enclave have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, plastic fuel tanks, 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, rearview cameras, rear cross-path warning and available around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the XC90 its highest rating: “Top Pick Plus” for 2021, a rating granted to only 68 vehicles tested by the IIHS. The Enclave last would have qualified as only a standard “Top Pick” in 2017.
