Both the Cullinan and Grand Cherokee 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 Grand Cherokee’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 Cullinan’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Grand Cherokee doesn’t offer a whiplash protection system.

The Cullinan has standard PostCrash, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Grand Cherokee doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Cullinan. But it costs extra on the Grand Cherokee.

Both the Cullinan and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available night vision systems.

The Rolls-Royce Cullinan weighs 666 to 1935 pounds more than the Jeep Grand Cherokee. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

The Cullinan comes with a full 4-year/unlimited-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Grand Cherokee’s 3-year/36,000-mile basic warranty expires 1 year 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. Jeep doesn’t pay scheduled maintenance for the Grand Cherokee.

Engine

The Cullinan’s standard 6.8 turbo V12 produces 270 more horsepower (563 vs. 293) and 367 lbs.-ft. more torque (627 vs. 260) than the Grand Cherokee Laredo’s standard 3.6 DOHC V6. The Cullinan’s 6.8 turbo V12 produces 239 more horsepower (563 vs. 324) and 295 lbs.-ft. more torque (627 vs. 332) than the Grand Cherokee’s optional 2.0 turbo 4-cylinder. The Cullinan Black Badge’s standard 6.8 turbo V12 produces 267 more horsepower (591 vs. 324) and 332 lbs.-ft. more torque (664 vs. 332) than the Grand Cherokee’s optional 2.0 turbo 4-cylinder.

As tested in Motor Trend the Cullinan Black Badge is faster than the Grand Cherokee Laredo 3.6 DOHC V6:

	Cullinan	Grand Cherokee
Zero to 60 MPH	4.7 sec	7.3 sec
Quarter Mile	13.1 sec	15.5 sec
Speed in 1/4 Mile	109.6 MPH	89.8 MPH

Fuel Economy and Range

The Cullinan has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Grand Cherokee. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Brakes and Stopping

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

	Cullinan	Grand Cherokee
Front Rotors	15.6 inches	13.9 inches
Rear Rotors	15.7 inches	13.8 inches

The Cullinan stops much shorter than the Grand Cherokee:

	Cullinan	Grand Cherokee
60 to 0 MPH	107 feet	142 feet	Motor Trend

Tires and Wheels

For better traction and acceleration, the Cullinan has larger standard rear tires than the Grand Cherokee (285/40R22 vs. 265/60R18). The Cullinan’s optional rear tires are larger than the largest rear tires available on the Grand Cherokee (295/35R23 vs. 275/45R21).

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 Grand Cherokee

’s standard 60 series tires. The Cullinan’s optional 255/40R23 front and 295/35R23 rear tires have a lower 40 series front and 35 series rear profile than the Grand Cherokee Summit’s 45 series tires.

For better ride, handling and brake cooling the Cullinan has standard 22-inch wheels. Smaller 18-inch wheels are standard on the Grand Cherokee

. The Cullinan’s optional 23-inch wheels are larger than the 21-inch wheels on the Grand Cherokee Summit.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires available on the Cullinan can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The Grand Cherokee doesn’t offer self-sealing tires.

Suspension and Handling

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 Grand Cherokee 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 Grand Cherokee, 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. Jeep doesn’t offer an active suspension on the Grand Cherokee.

For a smoother ride and more stable handling, the Cullinan’s wheelbase is 13 inches longer than on the Grand Cherokee (129.7 inches vs. 116.7 inches).

For better handling and stability, the track (width between the wheels) on the Cullinan is 1.6 inches wider in the front and .5 inches wider in the rear than on the Grand Cherokee.

The Cullinan Black Badge handles at .82 G’s, while the Grand Cherokee Limited 4x4 pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The Cullinan Black Badge executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the Grand Cherokee Limited 4x4 (26.6 seconds @ .68 average G’s vs. 28.1 seconds @ .58 average G’s).

Passenger Space

The Cullinan has 5 cubic feet more passenger volume than the Grand Cherokee (112 vs. 107).

The Cullinan has 2 inches more front headroom, 1 inch more rear headroom and 4.7 inches more rear legroom than the Grand Cherokee.

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 Grand Cherokee doesn’t offer tailgating seats.

Cargo Capacity

A low lift-over cargo hatch design makes loading and unloading the Cullinan easier. The Cullinan’s cargo hatch lift-over height is 30.7 inches, while the Grand Cherokee’s liftover is 33 inches.

The Cullinan’s cargo area is larger than the Grand Cherokee’s in almost every dimension:

	Cullinan	Grand Cherokee
Length to seat (2nd/1st)	44”/88.4”	41”/73.8”
Max Width	59.1”	55”
Min Width	32.8”	43”
Height	36”	32”

Pressing a switch automatically lowers or raises the Cullinan’s rear seats, to make changing between cargo and passengers easier. The Grand Cherokee doesn’t offer automatic folding seats.

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

Towing

The Cullinan’s standard towing capacity is much higher than the Grand Cherokee’s (7300 vs. 3500 pounds).

Ergonomics

The Cullinan’s front and rear power windows all lower 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 Grand Cherokee’s standard power windows’ rear power window switches have to be held the entire time to open them fully.

If the windows are left open on the Cullinan the driver can close all of them at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Grand Cherokee can only close the windows from inside the vehicle, with the ignition on.

The Cullinan’s standard Comfort Access allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Enter-N-Go standard on the Grand Cherokee doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

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 Grand Cherokee doesn’t offer a power rear door.

The Cullinan’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Grand Cherokee’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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

The Grand Cherokee Summit’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Cullinan’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The Rolls-Royce Cullinan has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors are only offered on the Grand Cherokee Summit.

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 is only available on the Grand Cherokee Laredo X/Altitude/Limited/Summit.

The Cullinan has standard massaging front seats. Massaging front seats are only available on the Grand Cherokee Summit. 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 Grand Cherokee.

The Rolls-Royce Cullinan has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Homelink® is only available on the Grand Cherokee Limited/Summit.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Rolls-Royce Cullinan has a standard wireless phone charging system (Qi) in the center console. Only the Grand Cherokee Laredo X/Altitude/Limited/Summit offers wireless charging.

The Cullinan’s optional Automatic Parking Assistant can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Grand Cherokee Summit’s automatic parking system requires operating the brakes and transmission to safely park.

Economic Advantages

According to iSeeCars.com the 2026 Rolls-Royce Cullinan retains 55.58% of its original value after 5 years, significantly more than the 47.26% resale value of the 2026 Jeep Grand Cherokee after five years, which can save the Rolls-Royce’s owner.
