Compare the2022 BMW X7VS 2022 Rolls-Royce Cullinan

Both the X7 and the Cullinan have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The X7’s corrosion warranty is 8 years longer than the Cullinan’s (12 vs. 4 years).

There are over 9 times as many BMW dealers as there are Rolls-Royce dealers, which makes it much easier should you ever need service under the X7’s warranty.

J.D. Power and Associates rated the X7 first among large premium suvs in their 2021 Initial Quality Study. The Cullinan isn’t in the top three in its category.

The Alpina XB7’s 4.4 turbo V8 produces 20 more horsepower (612 vs. 592) than the Cullinan Black Badge’s optional 6.8 turbo V12.

On the EPA test cycle the X7 gets better mileage than the Cullinan:

Regenerative brakes improve the X7’s fuel efficiency by converting inertia back into energy instead of wasting it. The Cullinan doesn’t offer a regenerative braking system.

In heavy traffic or at stop lights the X7’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Cullinan doesn’t offer an automatic engine start/stop system.

For more complete vehicle control the X7 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.

The X7’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Cullinan doesn’t offer launch control.

For better traction, the X7 has larger standard tires than the Cullinan (F:275/40R22 & R:315/35R22 vs. 255/50R21). The Alpina XB7’s optional tires are larger than the largest tires available on the Cullinan (F:285/35R23 & R:325/30R23 vs. 255/50R21).

The X7’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Cullinan’s standard 50 series tires. The Alpina XB7’s optional 285/35R23 front and 325/30R23 rear tires have a lower 35 series front and 30 series rear profile than the Cullinan’s optional 45 series tires.

For better ride, handling and brake cooling the Alpina XB7 offers optional 23-inch wheels. The Cullinan’s largest wheels are only 22-inches.

The X7 offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire 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 X7’s turning circle is .6 feet tighter than the Cullinan’s (42.8 feet vs. 43.4 feet).

The BMW X7 may be more efficient, handle and accelerate better because it weighs about 200 to 650 pounds less than the Rolls-Royce Cullinan.

The X7 is 7 inches shorter than the Cullinan, making the X7 easier to handle, maneuver and park in tight spaces.

For excellent aerodynamics, the X7 has standard flush composite headlights. The Cullinan has recessed headlights that spoil its aerodynamic shape and create extra drag.

The front grille of the X7 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Cullinan doesn’t offer active grille shutters.

The X7 has standard seating for 7 passengers; the Cullinan can only carry up to 5.

The X7’s cargo area provides more volume than the Cullinan.

The X7’s standard 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.

To make loading groceries and cargo easier when your hands are full, the X7’s tailgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Cullinan doesn’t offer a hands-free gesture to open its tailgate, forcing you to put cargo down if your hands are full.

The X7 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 X7’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 shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the X7 has standard extendable sun visors. The Cullinan doesn’t offer extendable visors.
