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 Sequoia 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 Toyota Sequoia doesn’t offer height-adjustable middle seat belts.
Both the XC90 and Sequoia 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 Sequoia’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. Toyota doesn’t offer the convenience and security of a built-in child booster seat in the Sequoia. 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 XC90 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 Sequoia 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.
Full-time four-wheel drive is standard on the XC90. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Sequoia. Four-wheel drive of any type costs extra on the Sequoia.
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 Sequoia doesn’t offer a driver alert monitor.
For better protection of the passenger compartment, the XC90 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Sequoia uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the XC90 and the Sequoia have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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 performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the XC90 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The Sequoia has not been tested, yet.
