Compare the2022 Rolls-Royce CullinanVS 2022 Infiniti QX80

Both the Cullinan and QX80 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 QX80’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.

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 QX80 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 QX80 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Cullinan. But it costs extra on the QX80.

When descending a steep, off-road slope, the Cullinan’s standard Hill Descent Control allows you to creep down safely. The QX80 doesn’t offer Hill Descent Control.

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 QX80 doesn’t offer a night vision system.

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 QX80 doesn’t offer a driver alert monitor.

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 QX80 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Cullinan and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

The Cullinan comes with a full 4-year/unlimited-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The QX80’s 4-year/60,000-mile basic warranty expires sooner.

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. Infiniti doesn’t pay scheduled maintenance for the QX80.

The Cullinan’s standard 6.8 turbo V12 produces 163 more horsepower (563 vs. 400) and 214 lbs.-ft. more torque (627 vs. 413) than the QX80’s 5.6 DOHC V8. The Cullinan Black Badge’s standard 6.8 turbo V12 produces 192 more horsepower (592 vs. 400) and 251 lbs.-ft. more torque (664 vs. 413) than the QX80’s 5.6 DOHC V8.

The Cullinan has 4.4 gallons more fuel capacity than the QX80 (30.4 vs. 26 gallons), for longer range between fill-ups.

An eight-speed automatic is standard on the Rolls-Royce Cullinan, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the QX80.

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 QX80 Luxe’s standard 60 series tires. The Cullinan’s optional tires have a lower 45 series profile than the QX80 Premium Select/Sensory’s 50 series tires.

For better ride, handling and brake cooling the Cullinan has standard 21-inch wheels. Smaller 20-inch wheels are standard on the QX80 Luxe.

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 QX80 doesn’t offer run-flat tires.

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 QX80 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 QX80, which uses coil springs in front. Air springs maintain proper ride height and ride more smoothly.

The Cullinan has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The QX80’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Cullinan’s wheelbase is 8.6 inches longer than on the QX80 (129.7 inches vs. 121.1 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 QX80 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 QX80 doesn’t offer tailgating seats.

The Cullinan has a much larger cargo volume than the QX80 with its rear seat up (43.4 vs. 16.6 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 QX80’s rear cargo window doesn’t open.

Unlike the driver-only memory system in the QX80, the Cullinan has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Cullinan has a standard heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The QX80 doesn’t offer a heads-up display.

The Cullinan’s power parking brake sets with one touch and releases with one touch or automatically. The QX80’s parking brake has to be released manually.

The power windows standard on both the Cullinan and the QX80 have locks to prevent small children from operating them. When the lock on the Cullinan is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX80 prevents the driver from operating the other windows just as it does the other passengers.

Manual rear side window sunshades are available in the Cullinan to help block heat and glare for the rear passengers. The QX80 doesn’t offer rear side window sunshades.

Optional air conditioned front and rear seats keep the Cullinan’s passengers comfortable and take the sting out of hot leather in summer. The QX80 doesn’t offer air-conditioned seats for the second row.

The Cullinan has standard massaging front and optional massaging rear seats. Massaging seats aren’t available in the QX80.

The Cullinan’s Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The QX80 doesn’t offer an automated parking system.
