The QX80’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Cullinan doesn’t offer pre-crash pretensioners.

Over 200 people are killed each year when backed over by motor vehicles. The QX80 offers optional Backup Collision Intervention that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Cullinan doesn’t offer backup collision prevention brakes.

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


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 almost 6 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.


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.

Suspension and Handling

The QX80 offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Rolls-Royce doesn’t offer an active suspension on the Cullinan.

For better maneuverability, the QX80’s turning circle is 2.1 feet tighter than the Cullinan’s (41.3 feet vs. 43.4 feet).


The Infiniti QX80 may be more efficient, handle and accelerate better because it weighs about 150 to 400 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.

Passenger Space

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).

Cargo Capacity

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.

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.


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.

Model Availability

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


Consumer Reports® recommends the Infiniti QX80, based on reliability, safety and performance.
