For enhanced safety, the front and second-row 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 Toyota Sequoia doesn’t offer pretensioners for its second-row 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 Sequoia doesn’t offer pre-crash pretensioners.
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.
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 Sequoia’s side 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 Sequoia doesn’t offer a whiplash protection system.
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.
Over 200 people are killed each year when backed over by motor vehicles. The XC90 has standard CTA Auto Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Sequoia doesn’t offer backup collision prevention brakes.
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.
When descending a steep, off-road slope, the XC90’s standard Hill Descent Control allows you to creep down safely. The Sequoia doesn’t offer Hill Descent Control.
The XC90 Plus/Ultimate has a standard 360-Degree Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The Sequoia only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the XC90 and Sequoia have rear cross-traffic warning, but the XC90 has Braking Intervention (automatically applies the brakes) to better prevent a collision when backing near traffic. The Sequoia’s Rear Cross Traffic Alert doesn’t automatically brake.
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, 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 driver alert 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.
