Compare the2025 Rolls-Royce CullinanVS 2025 Mercedes GLE Coupe

Both the Cullinan and GLE Coupe have child safety locks to prevent children from opening the rear doors. The Cullinan has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GLE Coupe’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Rolls-Royce Cullinan has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GLE Coupe doesn’t offer a front passenger side knee airbag.

A passive infrared night vision system optional on the Cullinan helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The GLE Coupe doesn’t offer a night vision system.

The Cullinan’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the GLE Coupe.

Both the Cullinan and the GLE Coupe 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 and driver alert monitors.

The Rolls-Royce Cullinan weighs 912 to 1199 pounds more than the Mercedes GLE Coupe. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The Cullinan comes with a full 4-year/unlimited-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The GLE Coupe’s 4-year/50,000-mile basic warranty expires sooner.

Rolls-Royce pays for scheduled maintenance on the Cullinan for 4 years and unlimited miles. Rolls-Royce will pay for oil changes, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLE Coupe.

The Cullinan’s standard 6.8 turbo V12 produces 188 more horsepower (563 vs. 375) and 258 lbs.-ft. more torque (627 vs. 369) than the GLE Coupe’s 3.0 turbo 6-cylinder hybrid. The Cullinan Black Badge’s standard 6.8 turbo V12 produces 217 more horsepower (592 vs. 375) and 295 lbs.-ft. more torque (664 vs. 369) than the GLE Coupe’s 3.0 turbo 6-cylinder hybrid.

The Cullinan has 1.3 gallons more fuel capacity than the GLE Coupe (23.8 vs. 22.5 gallons), for longer range between fill-ups.

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

For better traction and acceleration, the Cullinan has larger standard rear tires than the GLE Coupe (285/40R22 vs. 275/50R20).

The Cullinan’s standard 255/45R22 front and 285/40R22 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the GLE Coupe’s standard 50 series tires.

For better ride, handling and brake cooling the Cullinan has standard 22-inch wheels. Smaller 20-inch wheels are standard on the GLE Coupe. The Cullinan’s optional 23-inch wheels are larger than the 22-inch wheels optional on the GLE Coupe.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Cullinan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GLE Coupe doesn’t offer run-flat tires.

The Cullinan has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The GLE Coupe doesn’t offer an active sway bar system.

The front and rear suspension of the Cullinan uses air springs for a smoother, controlled ride than the GLE Coupe, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The Cullinan offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Mercedes doesn’t offer an active suspension on the GLE Coupe.

For a smoother ride and more stable handling, the Cullinan’s wheelbase is 14.1 inches longer than on the GLE Coupe (129.7 inches vs. 115.6 inches).

The Cullinan has 8 cubic feet more passenger volume than the GLE Coupe (112 vs. 104).

The Cullinan has 1.4 inches more front headroom and 2.6 inches more rear headroom than the GLE Coupe.

For enhanced passenger comfort on long trips the Cullinan’s rear seats recline. The GLE Coupe’s rear seats don’t recline.

Flexibility is maximized at the game, campground or a drive-in theatre in the Cullinan when its optional tailgating rear seats are deployed, allowing people to sit facing out of the tailgate. (Do not use while vehicle is in motion.) The GLE Coupe doesn’t offer tailgating seats.

The Cullinan has a larger cargo volume with its rear seat folded than the GLE Coupe with its rear seat folded (68.2 vs. 64.1 cubic feet).

The Cullinan’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The GLE Coupe’s rear cargo window doesn’t open.

The Cullinan’s power side reverse swing out doors make it much easier to load and unload kids and cargo. One touch opens the door, before you even get to the sport utility. The GLE Coupe doesn’t offer a power rear door.

To improve rear visibility by keeping the rear window clear, the Cullinan has a standard rear wiper. The GLE Coupe doesn’t offer a rear wiper.

Optional air conditioned front and rear seats keep the Cullinan’s passengers comfortable and take the sting out of hot leather in summer. The GLE Coupe doesn’t offer air-conditioned seats in the rear.

The Cullinan has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the GLE Coupe.

The Cullinan has standard massaging front seats. Massaging front seats cost extra on the GLE Coupe. The Cullinan also offers optional massaging rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging rear seats aren’t available in the GLE Coupe.
