The AMG GLC’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 AMG GLC’s warranty.

On the EPA test cycle the AMG GLC gets better mileage than the Cullinan:

In heavy traffic or at stop lights the AMG GLC’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.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GLC higher (5 out of 10) than the Rolls-Royce Cullinan (3). This means the AMG GLC produces up to 16.5 pounds less smog-producing pollutants than the Cullinan every 15,000 miles.

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

For better traction and acceleration, the AMG GLC has larger rear tires than the Cullinan (285/40R20 vs. 255/50R21).

The AMG GLC 43’s standard 255/45R20 front and 285/40R20 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 Cullinan’s standard 50 series tires. The AMG GLC 43’s optional 255/40R21 front and 285/35R21 rear tires have a lower 40 series front and 35 series rear profile than the Cullinan’s optional 45 series tires.

The AMG GLC offers an optional 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 AMG GLC’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 AMG GLC’s turning circle is 3.7 feet tighter than the Cullinan’s (39.7 feet vs. 43.4 feet).

The Mercedes AMG GLC may be more efficient, handle and accelerate better because it weighs about 1900 pounds less than the Rolls-Royce Cullinan.

The AMG GLC is 2 feet, 2.8 inches shorter than the Cullinan, making the AMG GLC easier to handle, maneuver and park in tight spaces.

The AMG GLC is 7.7 inches shorter in height than the Cullinan, making the AMG GLC much easier to wash and garage and drive (lower center of gravity).

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

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

The AMG GLC 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.
