A Range Rover SV starts at $185,600. A Rolls-Royce Cullinan Black Badge crests $440,000 before you touch the options sheet. In both cases, you get a large vehicle that seats five adults, carries roughly the same amount of luggage, and sits in the same traffic. The question is not whether these SUVs are comfortable — they all are. The question is which ones deliver something genuinely proportional to their price, and which are charging a steep premium for a grille and a badge.
Five SUVs sit at the top of this market: the Range Rover, Mercedes-AMG G 63, Bentley Bentayga, Porsche Cayenne Turbo GT, and Rolls-Royce Cullinan. Each approaches the idea of a premium SUV from a different direction. Some of those directions lead somewhere remarkable. Others lead to a parking valet who is more impressed than you will be after six months of ownership.
What Each SUV Actually Does Best
The has always been the most complete luxury SUV on paper. It rides better than anything else in this group on broken surfaces, partly because Land Rover has spent decades tuning long-travel air suspension for terrain that would destroy most competitors. The interior, particularly in SV Autobiography trim with the four-seat executive configuration, is genuinely quiet at highway speeds — measurably quieter than the Bentayga. It also wades through 900mm of water, which you will never do, but the engineering required to make that possible is what makes it feel so planted on a wet motorway.
The is the most honest vehicle here, in a perverse way. It does not pretend to be something it is not. The G-Wagon is a 1979 military truck chassis with a hand-built AMG twin-turbo V8 bolted to it, leather seats fitted inside, and a price tag of $185,900 that is roughly $60,000 more than it should be based on the engineering alone. What you are paying for is the shape, the sound of those three differential locks engaging, the door clunk, and the social currency. Mercedes knows this. The G 63 has the worst fuel economy in this group (14 mpg combined), the least refined ride, and the most body roll. It also has a two-year wait list.
The with the 4.0-liter twin-turbo V8 is the SUV that most successfully transplants a grand touring experience into a tall body. The ride quality sits between the Range Rover and the Cayenne — not quite as absorbent as the Range Rover over rough surfaces, but more composed at sustained high speed. The interior craftsmanship is the best in this group, full stop. Bentley's Crewe factory uses leather hides that are individually graded, and the diamond-quilted seats take roughly 20 hours of stitching per car. The Speed variant adds 600 horsepower and carbon-ceramic brakes, which feels like fitting a sprinter's shoes on a diplomat.
The is the outlier. It starts at approximately $195,000 and is the only vehicle in this group that would be genuinely entertaining on a mountain pass. The 4.0-liter twin-turbo V8 produces 631 horsepower, and the chassis tuning — stiffer springs, wider rear track, rear-axle steering — transforms the Cayenne from a competent SUV into something that can lap the Nurburgring in 7:38. That time would have been a respectable sports car lap fifteen years ago. The trade-off is the ride: the Turbo GT is noticeably firmer than the others, and at low speeds over rough roads, it reminds you constantly that it was tuned for a different purpose.
The is the most expensive and the most polarizing. Starting at $355,000 and typically optioned well past $400,000, the Cullinan offers the quietest cabin, the most theatrical presence, and coach doors that open to reveal a cabin trimmed in materials you will not find in any other production vehicle. The Starlight Headliner alone — 1,344 hand-placed fiber optic lights — takes 17 hours to install. Whether that matters depends entirely on what you want from a vehicle. As a driving machine, the Cullinan is merely adequate. As a mobile sanctuary, it is without peer.

Where Badge Engineering Shows
The G-Wagon is the clearest case of badge premium in this group. Strip away the emotional appeal and you have a body-on-frame SUV with live axles, a high center of gravity, and fuel economy that belongs in 2008. The interior materials are Mercedes-standard — high quality, certainly, but not demonstrably better than what you get in an AMG GLE 63 S that costs $50,000 less and rides significantly better. The G 63 survives on mystique, and that mystique is real, but it is not an engineering achievement at its price point.
The Cullinan has a subtler version of the same issue. Rolls-Royce builds genuinely remarkable interiors, but the platform it sits on is BMW's CLAR architecture — the same bones underneath a 7 Series. The engine is a version of BMW's N74 twin-turbo V12. This is not a criticism of the engineering; both are excellent. But when the price premium over a BMW X7 M60i is more than $250,000, buyers should understand that a significant portion of that gap pays for the Spirit of Ecstasy, the coach doors, and the hand-finished interior — not fundamentally different underpinnings.
The Range Rover suffers from the opposite problem. The engineering is distinctive and genuinely world-class for off-road capability and ride quality. But Land Rover's reliability record casts a long shadow. Electrical gremlins, infotainment failures, and air suspension faults are documented with uncomfortable regularity. A vehicle at this price should not need three warranty visits in its first year, yet many owners report exactly that. The SV models are hand-finished at Land Rover's Special Vehicle Operations center, but they still share an electrical architecture with the standard Range Rover — and that architecture has proven fragile.
The Off-Road Honesty Test
Four of these five SUVs are marketed with some reference to capability beyond tarmac. Only one actually goes off-road with any regularity.
The Range Rover remains the only genuinely capable off-road vehicle in this group. Its Terrain Response 2 system, wading depth, approach and departure angles, and low-range transfer case are not marketing exercises — they are functional. Land Rover runs experience centers where customers drive these vehicles through axle-deep mud and up rock faces. No other manufacturer in this class does that because no other vehicle in this class can.
The G-Wagon has legitimate off-road hardware — three locking differentials, low range, and solid axles that provide excellent articulation. In practice, almost none of them leave pavement. The few that do tend to be older G 500s and G 350d models, not the $186,000 G 63 with 22-inch wheels and summer tires. The current G 63's approach angle with its AMG bumper is significantly compromised compared to the G 500 Professional that militaries and expeditions actually use.
The Cayenne, Bentayga, and Cullinan are road vehicles. They have all-wheel drive, decent ground clearance, and enough traction control programming to handle a gravel driveway or a snowy mountain road. None of them should be taken off-road in any meaningful sense, and none of them are designed for it. This is not a flaw — it is a design choice. But if off-road capability is even a minor consideration, the Range Rover is the only serious answer.
Towing: The Specification Nobody Checks Until They Need It
Towing capacity is where these vehicles reveal their intended use most clearly.
Towing Capacity Comparison
| Model | Max Towing | Tongue Weight | Practical Notes |
|---|---|---|---|
| Range Rover SV | 7,716 lbs | 772 lbs | Best towing dynamics, trailer stability assist standard |
| Mercedes-AMG G 63 | 7,000 lbs | 727 lbs | High center of gravity makes trailer sway more noticeable |
| Bentley Bentayga | 7,716 lbs | 772 lbs | Adequate, but the Bentayga was not designed around towing |
| Porsche Cayenne Turbo GT | 7,700 lbs | 770 lbs | Strong capacity on paper, but GT suspension tuning is harsh when loaded |
| Rolls-Royce Cullinan | 5,500 lbs | N/A | Rolls-Royce does not officially promote towing |
The Range Rover is the clear winner here. Its air suspension self-levels under load, the integrated trailer stability program works well, and the towing experience feels considered rather than bolted on as an afterthought. If you are pulling a horse trailer, a boat, or a caravan, the Range Rover is the only SUV in this group designed with that use genuinely in mind.
The Cullinan's relatively low towing figure tells you everything about Rolls-Royce's customer. They do not expect Cullinan buyers to hitch anything to the back. They expect them to have someone else tow it.
Depreciation: Where the Money Goes
This is where the conversation gets uncomfortable for some of these vehicles. As covered in our depreciation analysis, luxury SUVs follow wider patterns than their sports car counterparts — but with meaningful variation between models.
The G-Wagon depreciates the least in this group, and it is not close. Three-year residual values consistently sit between 65-72% of MSRP, and certain colors and configurations (matte finishes, limited editions like the G 63 4x4 Squared) actually appreciate. This is purely a function of demand exceeding supply. Mercedes limits production deliberately, and the wait list acts as a price floor on the secondary market.
The Cayenne holds respectably — roughly 55-60% after three years for the Turbo GT, which benefits from limited production numbers and genuine performance credentials. Porsche's general residual strength applies here, though the Cayenne depreciates faster than the 911 or the sport-oriented models.
The Range Rover historically depreciates steeply — 40-50% in three years for most configurations. The SV variants hold slightly better, but the reliability reputation drags resale down. Buyers factor in the likelihood of expensive repairs when purchasing used, and they price accordingly. This makes a two-year-old Range Rover one of the better values in the segment, which is both a buying opportunity and an indictment.
The Bentayga sits in similar territory to the Range Rover — roughly 45-55% residual after three years. The first-generation Bentayga depreciated brutally, and while the current model is holding better, it has not matched Porsche or Mercedes on residuals. The real cost of owning a vehicle at this level goes well beyond the sticker price.
The Cullinan holds its value reasonably well for its price bracket — 55-65% after three years — partly because production numbers are low and partly because the clientele buying Cullinans tend to order heavily optioned cars that retain specification appeal on the secondary market. The Black Badge versions hold best.
Running Costs Nobody Advertises
Annual insurance on a Cullinan runs $4,500-$8,000 depending on location and driving record. The G 63 is similar. The Cayenne Turbo GT, despite being the fastest vehicle here, is often the least expensive to insure because Porsche owners statistically file fewer claims.
Maintenance costs vary dramatically. A Bentley Bentayga major service (typically at 20,000 miles) runs $3,500-$5,000 at a dealer. The Cayenne's equivalent is $1,800-$2,800. Rolls-Royce service pricing is deliberately opaque — expect $2,000-$4,000 for routine work and significantly more for anything involving the suspension or electrical systems.
Tire replacement is a consistent expense across the group. Most of these vehicles wear 22-inch or larger wheels with performance-oriented tires that cost $400-$600 each. The Cayenne Turbo GT's staggered 22-inch setup with sport tires is the most expensive to replace at roughly $2,800 for a full set. And on these vehicles, tire life is short — 15,000 to 25,000 miles depending on driving style.
Fuel costs are the slow bleed. At $4 per gallon and 12,000 miles per year, the G 63 costs roughly $3,400 per year in fuel. The Range Rover, with marginally better economy, runs about $2,800. The electric alternatives at this price point are worth considering if fuel costs factor into your calculation — though none of the electric SUVs yet match what these vehicles offer in presence or interior quality.
The Verdict, By Use Case
If you want one vehicle that does nearly everything well — long-distance comfort, genuine off-road capability, towing, motorway refinement — the Range Rover remains the most versatile SUV in this class. Buy the extended warranty and budget for reliability issues, because they are likely. Its engineering justifies the price; its quality control does not always.
If you want the SUV that will still look good in photographs twenty years from now and depreciate the least, buy the G-Wagon. Accept that you are paying for design heritage, social signaling, and a sound that no other SUV makes. You are not paying for the best ride, the best interior, or the best technology. That is fine — the G 63's appeal has never been rational, and the resale numbers prove the market agrees.
If you want the finest interior and a grand touring character that rewards long drives, the Bentayga in V8 specification is the considered choice. Skip the Speed unless you genuinely want 190 mph capability from a 5,580-pound vehicle. The standard car rides better and costs $30,000 less.
If you actually enjoy driving — not being driven, not commuting, but taking a vehicle on a road where the corners matter — the Cayenne Turbo GT is the only SUV here that belongs in the conversation. It is also the only one that does not feel like a compromise when you park it next to a sports car at a mountain pass. The ride is firm. The exhaust is loud. If those are problems for you, this is not your vehicle.
If money is genuinely no object, the Cullinan delivers an experience no other SUV matches — but that experience is entirely about the rear seat, the silence, and the theater of arrival. As a driver's car, it is ordinary. As a mobile statement of wealth, nothing else comes close.
The best luxury SUV is the one that matches how you actually live, not the one with the highest price or the most recognizable badge. Most buyers in this segment would be better served by a well-optioned Cayenne or Range Rover than a Cullinan they drive twice a month.
The uncomfortable truth of this segment is that capability and price are not linearly correlated. The $195,000 Cayenne Turbo GT is a better vehicle, by most objective measures, than the $440,000 Cullinan. The $185,600 Range Rover SV is more capable than the $230,000 Bentayga in virtually every scenario except sustained Autobahn cruising. What you are paying for, past a certain threshold, is not engineering — it is identity. Whether that premium is justified is a question only you can answer, and the honest answer depends on how much of your satisfaction comes from driving and how much comes from arriving.
