Compare the2023 Rolls-Royce CullinanVS 2023 Lexus LX

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 LX doesn’t offer pre-crash pretensioners.

Both the Cullinan and LX have child safety locks to prevent children from opening the rear doors. The Cullinan 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 LX’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.

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 LX doesn’t offer a night vision system.

For better protection of the passenger compartment, the Cullinan 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 LX uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Cullinan and the LX 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, around view monitors, rear cross-path warning and driver alert monitors.

The Cullinan comes with a full 4-year/unlimited-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The LX’s 4-year/50,000-mile basic warranty expires sooner.

Rolls-Royce pays for scheduled maintenance on the Cullinan for 3 years and -10,000 miles longer than Lexus pays for maintenance for the LX (4/unlimited vs. 1/10,000).

The Cullinan’s standard 6.8 turbo V12 produces 154 more horsepower (563 vs. 409) and 148 lbs.-ft. more torque (627 vs. 479) than the LX’s 3.4 turbo V6. The Cullinan Black Badge’s standard 6.8 turbo V12 produces 183 more horsepower (592 vs. 409) and 185 lbs.-ft. more torque (664 vs. 479) than the LX’s 3.4 turbo V6.

The Cullinan has 2.7 gallons more fuel capacity than the LX (23.8 vs. 21.1 gallons), for longer range between fill-ups.

For better stopping power the Cullinan’s front brake rotors are larger than those on the LX:

The Cullinan’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the LX Premium/Luxury’s 65 series tires. The Cullinan’s optional tires have a lower 45 series profile than the LX’s optional 50 series tires.

For better ride, handling and brake cooling the Cullinan has standard 21-inch wheels. Smaller 18-inch wheels are standard on the LX Premium/Luxury.

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 LX doesn’t offer run-flat tires.

For superior ride and handling, the Rolls-Royce Cullinan has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Lexus LX has a solid rear axle, with a non-independent rear suspension.

The Cullinan has standard front and rear stabilizer bars, which help keep the Cullinan flat and controlled during cornering. The LX base model’s suspension doesn’t offer a rear stabilizer bar.

The Cullinan has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The LX doesn’t offer an active sway bar system.

The front and rear suspension of the Cullinan uses air springs for a smoother, controlled ride than the LX, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The Cullinan offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Lexus doesn’t offer an active suspension on the LX.

For a smoother ride and more stable handling, the Cullinan’s wheelbase is 17.5 inches longer than on the LX (129.7 inches vs. 112.2 inches).

Unibody construction lowers the Cullinan’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The LX uses body-on-frame design instead.

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 LX doesn’t offer tailgating seats.

The Cullinan has a much larger cargo volume with its rear seat up than the LX with its rear seat up (19.8 vs. 11 cubic feet). The Cullinan has a much larger cargo volume with its rear seat folded than the LX with its rear seat folded (68.2 vs. 64 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 LX’s rear cargo window doesn’t open.

The Cullinan’s power side reverse swing out doors make it much easier to load and unload kids and cargo. One touch opens the door, before you even get to the sport utility. The LX doesn’t offer a power rear door.

The LX’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Cullinan’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The Cullinan has standard massaging front and optional massaging rear seats. Massaging seats aren’t available in the LX.

The Cullinan’s Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The LX doesn’t offer an automated parking system.
