For enhanced safety, the middle seat shoulder belts of the BMW X7 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.
Both the X7 and Cullinan have rear cross-traffic warning, but the X7 has Cross Traffic Warning with braking function (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 X7 and the Cullinan have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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.
