Compare the2023 Mercedes AMG GLEVS 2023 Rolls-Royce Cullinan

For enhanced safety, the front seat shoulder belts of the Mercedes AMG GLE 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.

Both the AMG GLE and Cullinan have rear cross-traffic warning, but the AMG GLE has Active Brake Assist (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 AMG GLE and the Cullinan have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available lane departure warning systems and around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, with its optional vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the AMG GLE its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The Cullinan has not been tested, yet.

The AMG GLE’s corrosion warranty is 1 year longer than the Cullinan’s (5 vs. 4 years).

There are over 10 times as many Mercedes dealers as there are Rolls-Royce dealers, which makes it much easier should you ever need service under the AMG GLE’s warranty.

The AMG GLE 63 S’ standard 4.0 turbo V8 hybrid produces 11 more horsepower (603 vs. 592) than the Cullinan Black Badge’s standard 6.8 turbo V12.

On the EPA test cycle the AMG GLE gets better mileage than the Cullinan:

An engine control system that can shut down some of the engine’s cylinders helps improve the AMG GLE 63 S’ fuel efficiency. The Cullinan doesn’t offer a system that can shut down part of the engine.

Regenerative brakes improve the AMG GLE’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 stoplights the AMG GLE’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.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GLE higher (5 to 6 out of 10) than the Rolls-Royce Cullinan (3). This means the AMG GLE produces up to 23.4 pounds less smog-producing pollutants than the Cullinan every 15,000 miles.

For more complete vehicle control the AMG GLE 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.

A nine-speed automatic is standard on the Mercedes AMG GLE, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Cullinan.

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

The AMG GLE offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Cullinan doesn’t offer ceramic brake rotors.

For better traction, the AMG GLE has larger standard tires than the Cullinan (275/50R20 vs. 255/50R21). The AMG GLE’s optional tires are larger than the largest tires available on the Cullinan (F:285/40R22 & R:325/35R22 vs. 255/50R21).

The AMG GLE’s optional 285/40R22 front and 325/35R22 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Cullinan’s optional 45 series tires.

The AMG GLE has a standard 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.

The AMG GLE’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Cullinan doesn’t offer drift compensation steering.

For better maneuverability, the AMG GLE’s turning circle is 3.9 feet tighter than the Cullinan’s (39.4 feet vs. 43.3 feet).

The Mercedes AMG GLE may be more efficient, handle and accelerate better because it weighs about 850 to 1200 pounds less than the Rolls-Royce Cullinan.

The AMG GLE 53 is 1 foot, 4.5 inches shorter than the Cullinan, making the AMG GLE easier to handle, maneuver and park in tight spaces.

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

The AMG GLE offers optional seating for 7 passengers; the Cullinan can only carry up to 5.

The AMG GLE has a much larger cargo volume with its rear seat up than the Cullinan with its rear seat up (33.3 vs. 19.8 cubic feet). The AMG GLE has a much larger cargo volume with its rear seat folded than the Cullinan with its rear seat folded (74.9 vs. 68.2 cubic feet).

The AMG GLE’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.

The AMG GLE’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.

To make loading groceries and cargo easier when your hands are full, the AMG GLE’s liftgate 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.

Optional Trailer Stability Assist on the AMG GLE uses the Electronic Stability Program 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 AMG GLE 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 AMG GLE’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.

Heated windshield washer fluid is optional on the AMG GLE to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Cullinan doesn’t offer heated windshield washer fluid.

To better shield the driver and front passenger’s vision, the AMG GLE has standard dual-element sun visors that can block glare from two directions simultaneously. The Cullinan doesn’t offer secondary sun visors.

The AMG GLE 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 Mercedes GLE outsold the Rolls-Royce Cullinan by almost 67 to one during 2022.
