Compare the2024 Mercedes GLEVS 2023 Rolls-Royce Cullinan

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

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLE has Car-to-X Communication, a system that seemlesly communicates important warnings to the driver about impending danger, if they're available. The Cullinan doesn’t offer a system that can receive automated systems from other vehicles.

Both the GLE and Cullinan have rear cross-traffic warning, but the 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 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, around view monitors, rear cross-path warning, driver alert monitors and available lane departure warning systems.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the GLE its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 58 vehicles tested by the IIHS. The Cullinan has not been tested, yet.

The 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 GLE’s warranty.

On the EPA test cycle the GLE running its gasoline engine gets better mileage than the Cullinan:

The GLE 450e can travel with zero emissions for 38 miles. The Cullinan can’t move without running its internal combustion engine.

Regenerative brakes improve the GLE 450/580’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 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.

For more complete vehicle control the 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 GLE, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Cullinan.

For better traction, the GLE’s optional tires are larger than the largest tires available on the Cullinan (F:275/45R21 & R:315/40R21 vs. 255/50R21).

The GLE 450’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Cullinan’s optional 45 series tires.

The 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 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 GLE’s turning circle is 3.9 feet tighter than the Cullinan’s (39.4 feet vs. 43.3 feet).

The Mercedes GLE may be more efficient, handle and accelerate better because it weighs about 550 to 1400 pounds less than the Rolls-Royce Cullinan.

The GLE is 1 foot, 4.6 inches shorter than the Cullinan, making the GLE easier to handle, maneuver and park in tight spaces.

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

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

The 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 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 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 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 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 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 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 GLE’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 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 nozzles are optional on the GLE to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Cullinan doesn’t offer heated windshield washer nozzles.

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

The GLE offers an optional 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.
