Compare the2023 Infiniti QX80VS 2023 Rolls-Royce Cullinan

For enhanced safety, the front and middle seat shoulder belts of the Infiniti QX80 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.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the QX80 are reminded to check the back seat if they opened the rear door before starting out. The Cullinan doesn’t offer a back seat reminder.

Both the QX80 and Cullinan have rear cross-traffic warning, but the QX80 has Back-up Collision Intervention (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 QX80 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, 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, rear cross-path warning and available all wheel drive.

Infiniti’s powertrain warranty covers the QX80 2 years longer than Rolls-Royce covers the Cullinan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Cullinan ends after only 4 years.

The QX80’s corrosion warranty is 3 years longer than the Cullinan’s (7 vs. 4 years).

There are over 5 times as many Infiniti dealers as there are Rolls-Royce dealers, which makes it much easier should you ever need service under the QX80’s warranty.

On the EPA test cycle the QX80 gets better mileage than the Cullinan:

The QX80 has 2.2 gallons more fuel capacity than the Cullinan (26 vs. 23.8 gallons), for longer range between fill-ups.

For more complete vehicle control the QX80 has a manually controlled automatic, with the available convenience of an automatic transmission and the complete gear control of a manual transmission without the inconvenience of a clutch. A manually controlled automatic allows the driver to eliminate unwanted shifts and maximize engine braking by down shifting while cornering. The Cullinan doesn’t offer a transmission that allows complete gear control.

For better traction, the QX80 has larger tires than the Cullinan (275/60R20 vs. 255/50R21).

The Infiniti QX80’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Rolls-Royce Cullinan only has 5 wheel lugs per wheel.

The QX80 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Cullinan doesn’t offer vehicle monitored tire inflation.

The QX80 has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Cullinan; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

For better maneuverability, the QX80’s turning circle is 2 feet tighter than the Cullinan’s (41.3 feet vs. 43.3 feet).

The Infiniti QX80 may be more efficient, handle and accelerate better because it weighs about 250 to 600 pounds less than the Rolls-Royce Cullinan.

For excellent aerodynamics, the QX80 has standard flush composite headlights. The Cullinan has recessed headlights that spoil its aerodynamic shape and create extra drag.

The QX80 offers optional seating for 8 passengers; the Cullinan can only carry up to 5.

The QX80 has 40.5 cubic feet more passenger volume than the Cullinan (152.5 vs. 112).

The QX80’s cargo area provides more volume than the Cullinan.

The QX80’s available rear seats fold to accommodate long and bulky cargo. The Cullinan w/Executive Rear Seats doesn’t offer folding rear seats, only a ski pass-through.

The QX80’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The Cullinan’s tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

Standard Trailer Sway Control on the QX80 uses the Vehicle Dynamic Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Cullinan doesn’t offer electronic trailer sway control.

The QX80 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cullinan doesn’t offer a remote starting system.

The QX80’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Cullinan does not have an oil pressure gauge.

The QX80’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Cullinan’s rear power window switches have to be held the entire time to close them fully.

To improve rear visibility by keeping the rear window clear, the QX80 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Cullinan only has an intermittent setting, so in a hard rain visibility isn’t as good.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The QX80 Sensory has standard headlight washers to keep headlight output high. The Cullinan doesn’t offer headlight washers.

The QX80 Sensory has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Cullinan doesn’t offer a house-current electrical outlet.

The QX80 is available in both rear-wheel drive and four-wheel drive configurations. The Cullinan doesn’t offer a two-wheel drive configuration.

The Infiniti QX80 outsold the Rolls-Royce Cullinan by almost 8 to one during 2022.
