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

The Grand Cherokee SRT has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed.

The Jeep Grand Cherokee SRT may be more efficient, handle and accelerate better because it weighs about 850 pounds less than the Rolls-Royce Cullinan.

The Grand Cherokee SRT is 1 foot, 8.5 inches shorter than the Cullinan, making the Grand Cherokee SRT easier to handle, maneuver and park in tight spaces.

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

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

The Grand Cherokee 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.

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 Grand Cherokee SRT’s Parallel and Perpendicular Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Cullinan doesn’t offer an automated parking system.
