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 Rolls-Royce Cullinan doesn’t offer height-adjustable seat belts.
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. Rolls-Royce doesn’t offer the convenience and security of a built-in child booster seat in the Cullinan. 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 Cullinan’s side airbags don’t have smart features and will always deploy full force.
Both the XC90 and Cullinan 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 Cullinan’s Cross Traffic Warning doesn’t automatically brake.
Both the XC90 and the Cullinan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors 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 Cullinan has not been tested, yet.
