The Cullinan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Range Rover doesn’t offer pre-crash pretensioners.
The Rolls-Royce Cullinan has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Range Rover doesn’t offer knee airbags.
The Cullinan has standard PostCrash, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Range Rover 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 Cullinan has standard Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Range Rover doesn’t offer backup collision prevention brakes.
A passive infrared night vision system optional on the Cullinan helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Range Rover doesn’t offer a night vision system.
The Cullinan has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Range Rover’s blind spot costs extra.
To help make backing out of a parking space safer, the Cullinan has standard Cross Traffic Warning, helping the driver avoid collisions. Land Rover charges extra for rear cross-path warning on the Range Rover.
Both the Cullinan and the Range Rover have standard driver and passenger frontal airbags, front side-impact 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, daytime running lights, lane departure warning systems and rearview cameras.
The Rolls-Royce Cullinan weighs 576 to 1319 pounds more than the Land Rover Range Rover. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
