Compare the2022 Rolls-Royce CullinanVS 2022 Bentley Bentayga

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 Bentayga doesn’t offer knee airbags.

The Cullinan has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Bentayga 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 and automatically apply the brakes to prevent a rear collision. The Bentayga doesn’t offer backup collision prevention brakes.

The Cullinan’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the Bentayga.

The Cullinan’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 Bentayga doesn’t offer a driver alert monitor.

Both the Cullinan and the Bentayga have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, around view monitors, rear cross-path warning and available night vision systems.

The Rolls-Royce Cullinan weighs 456 to 727 pounds more than the Bentley Bentayga. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The Cullinan comes with a full 4-year/unlimited-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Bentayga’s 3-year/unlimited-mile basic warranty expires 1 year sooner.

The Cullinan’s corrosion warranty is 1 year longer than the Bentayga’s (4 vs. 3 years).

Rolls-Royce pays for scheduled maintenance on the Cullinan for 4 years and unlimited miles. Rolls-Royce will pay for oil changes, lubrication and any other required maintenance. Bentley doesn’t pay scheduled maintenance for the Bentayga.

The Cullinan’s standard 6.8 turbo V12 produces 21 more horsepower (563 vs. 542) and 59 lbs.-ft. more torque (627 vs. 568) than the Bentayga’s standard 4.0 turbo V8.

On the EPA test cycle the Cullinan gets better mileage than the Bentayga:

The Cullinan has 7.9 gallons more fuel capacity than the Bentayga (30.4 vs. 22.5 gallons), for longer range between fill-ups.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the Cullinan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Bentayga doesn’t offer run-flat tires.

For a smoother ride and more stable handling, the Cullinan’s wheelbase is 11.8 inches longer than on the Bentayga (129.7 inches vs. 117.9 inches).

Flexibility is maximized at the game, campground or a drive-in theatre in the Cullinan when its optional tailgating rear seats are deployed, allowing people to sit facing out of the tailgate. (Do not use while vehicle is in motion.) The Bentayga doesn’t offer tailgating seats.

The Cullinan has a much larger cargo volume with its rear seat up than the Bentayga with its rear seat up (43.4 vs. 8 cubic feet). The Cullinan has a much larger cargo volume with its rear seat folded than the Bentayga with its rear seat folded (68.2 vs. 62.6 cubic feet).

The Cullinan’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The Bentayga’s rear cargo window doesn’t open.

If the windows are left open on the Cullinan the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Bentayga can only operate the windows from inside the vehicle, with the ignition on.

The Cullinan’s Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Bentayga’s automatic parking system requires operating the brakes and transmission to safely park.
