Dodge’s powertrain warranty covers the Durango SRT 1 year longer than Rolls-Royce covers the Cullinan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Cullinan ends after only 4 years.

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

There are over 65 times as many Dodge dealers as there are Rolls-Royce dealers, which makes it much easier should you ever need service under the Durango SRT’s warranty.

The Dodge Durango SRT’s engine uses a cast iron block for durability, while the Cullinan’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

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

For more complete vehicle control the Durango SRT 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 Durango SRT’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 Durango SRT has larger tires than the Cullinan (295/45R20 vs. 255/50R21).

The Durango SRT’s 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 Durango SRT 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.

For better maneuverability, the Durango SRT’s turning circle is 2.4 feet tighter than the Cullinan’s (41 feet vs. 43.4 feet).

The Dodge Durango SRT may be more efficient, handle and accelerate better because it weighs about 550 pounds less than the Rolls-Royce Cullinan.

The Durango SRT is 9.1 inches shorter than the Cullinan, making the Durango SRT easier to handle, maneuver and park in tight spaces.

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

The Durango SRT uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Cullinan doesn’t offer active noise cancellation.

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

The Durango SRT has 28.3 cubic feet more passenger volume than the Cullinan (140.3 vs. 112).

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

85.1 cubic feet

68.2 cubic feet

The Durango SRT’s available rear seats fold to accommodate long and bulky cargo. The Cullinan w/Executive Rear Seats doesn’t offer folding rear seats.

The Durango SRT’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.

The Durango SRT 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 Durango SRT’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.

To improve rear visibility by keeping the rear window clear, the Durango SRT has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Cullinan only has an intermittent setting, so in a hard rain visibility isn’t as good.

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

The Durango SRT 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.
