Few debates in the world of high-end motoring stir as much passion as GLS vs Cullinan, a contest between two very different interpretations of what an ultra-luxury SUV should be. One is a German flagship built on decades of engineering discipline, the other a British icon that simply decided an SUV could be a Rolls-Royce. Anyone shopping this segment in the UAE will eventually find their way to a proper car showroom near me to see both philosophies up close, and that is exactly where this comparison is heading.
Before diving into the detail, it helps to understand where each model sits in its own line-up and in the wider Dubai market. The Mercedes-Maybach GLS represents the pinnacle of Mercedes-Benz's SUV range, while the Rolls-Royce Cullinan sits at the very top of the marque's entire catalogue, SUV or otherwise. Buyers comparing the two are rarely choosing on badge alone; they are weighing presence, craftsmanship and character. For a wider look at what else sits alongside these two in the region's top tier, our full luxury cars inventory is worth browsing before any decision is made.
Dourado Luxury Cars currently showcases a 2022 Rolls-Royce Cullinan Black Badge finished with the Novitec Spofec kit, a combination that sharpens an already imposing SUV into something more purposeful. For buyers who want to see the Cullinan side of this comparison in its most aggressive form, the Rolls-Royce Cullinan by Onyx Concept in Deep Salamanca Blue offers another bespoke take on the same formula, while our featured example leans into Novitec's motorsport-inspired engineering.
Two Philosophies of Ultra-Luxury
The Mercedes-Maybach GLS approaches luxury through refinement and technology. It wraps the GLS platform in extended wheelbases, additional sound insulation, reclining rear seats and the kind of digital feature set that Mercedes has long been known for. The Rolls-Royce Cullinan, by contrast, approaches luxury through presence and craftsmanship. It is built on Rolls-Royce's own aluminium spaceframe architecture, shared with the Phantom and Ghost, and every panel, switch and stitch is designed to feel handmade rather than mass-produced.
Neither approach is wrong. The GLS suits buyers who want measurable, specification-driven luxury. The Cullinan suits those who want a statement that cannot be replicated by any other manufacturer, British or otherwise.
Design and Road Presence
On design, the two could not be more different. The GLS follows a conventional SUV silhouette with Mercedes' familiar grille and sweeping lines, projecting confidence without shouting. The Cullinan does the opposite. Its upright Pantheon grille, coach doors and vertical headlamps give it an unmistakable silhouette that commands attention at every junction on Sheikh Zayed Road. With the Novitec Spofec kit fitted to our showroom example, that presence is amplified further through a more aggressive aerodynamic package and distinctive wheel design.
Interior Craftsmanship
Step inside and the contrast continues. The Mercedes-Maybach GLS interior leans on technology, with expansive screens, ambient lighting and first-class-style rear comfort features. The Rolls-Royce Cullinan interior leans on materials and handwork, with options such as starlight headliners, open-pore wood finished by hand, and leather selected and fitted by craftspeople rather than automated processes. A few points worth noting when comparing cabin experiences:
- The Cullinan offers a genuine sense of occasion through its materials and finishing, rather than screen count alone
- The GLS focuses heavily on configurable comfort features and driver-assistance technology
- Both offer four-seat and bench-seat rear configurations depending on specification
- Rolls-Royce's Black Badge trim, as fitted to our featured car, adds a darker, more purposeful interior theme
- Tuner packages from the likes of Novitec or Onyx Concept can further personalise either cabin's exterior and trim
Performance and Engineering
Underneath, the GLS typically pairs a refined six-cylinder or V8 powertrain with air suspension tuned for comfort rather than outright pace. The Cullinan Black Badge, meanwhile, uses a 6.75-litre twin-turbocharged V12 producing 720 hp in this uprated form, delivering effortless, near-silent acceleration that feels at odds with the vehicle's considerable size. The Novitec Spofec kit fitted to Dourado's example sharpens this further, with aerodynamic revisions that work alongside Rolls-Royce's own planar suspension system rather than against it.
This is ultimately where the two cars diverge most clearly. The GLS is engineered to be comfortable and composed. The Cullinan, particularly in Black Badge form, is engineered to be commanding, with power delivery that feels proportionate to its presence on the road.
Dourado's Featured Cullinan Black Badge
The specific car at the centre of this comparison is a 2022 Rolls-Royce Cullinan Black Badge finished in Jubilee Silver over black, fitted with the Novitec Spofec kit and powered by that 720 hp V12. It represents one of the more complete expressions of the Cullinan formula currently available in Dubai, combining factory Black Badge character with a recognised European tuning house's aerodynamic and styling programme. Buyers interested in alternative specifications can also view the Rolls Royce Cullinan NEEV Limited Edition, a one-of-one example built by Onyx Concept, within the wider Rolls-Royce range at Dourado.
Onyx Concept, the London-based tuning house established in 2009 and Dourado's official Middle East dealer, has built a reputation for bespoke Rolls-Royce and Range Rover programmes that complement rather than compromise the original engineering, and several of its Cullinan interpretations sit alongside this featured car in our showroom.
Which Super-SUV Suits Dubai Better?
For Dubai and the wider UAE, both cars have an obvious audience. The Mercedes-Maybach GLS suits buyers who want flagship luxury without stepping outside the Mercedes ecosystem, and who value configurable technology as much as comfort. Readers wanting to explore that side of the comparison can start with the Mercedes collection. The Rolls-Royce Cullinan suits buyers who want their SUV to be instantly recognisable as a Rolls-Royce, with the handcrafted detailing and road presence that only the Rolls Royce collection can offer. Further technical specifications on the Cullinan's engineering can be found on the manufacturer's own site at Rolls-Royce Motor Cars.
Whichever side of this debate appeals most, the best way to decide is to experience both in person. Visit Dourado Luxury Cars in Al Quoz to see the Rolls-Royce Cullinan Black Badge with Novitec Spofec kit up close, or browse our showroom's wider range of ultra-luxury SUVs before booking a viewing.
