The Rolls-Royce Cullinan stands out as one of the most exclusive, luxurious, and expensive SUVs on the market, and when compared to other high-end luxury SUVs, it offers an unmatched combination of craftsmanship, performance, and prestige. Here's how the Cullinan compares to some of its primary competitors in the luxury SUV segment:

1. Price

• Rolls-Royce Cullinan: Starts at $350,000, with the potential to reach over $400,000 with bespoke options.
• Bentley Bentayga: Starts around $180,000 for the V8 model, with the W12 or Speed models nearing $250,000+.
• Lamborghini Urus: Starts at about $225,000.
• Mercedes-Maybach GLS 600: Around $170,000.
• Porsche Cayenne Turbo S E-Hybrid: Starts at $170,000.

In terms of price, the Cullinan is in a different league, often reserved for the ultra-wealthy. The Bentley Bentayga and Lamborghini Urus are high-end luxury SUVs, but the Cullinan is considered the pinnacle of automotive opulence.

2. Performance

• Rolls-Royce Cullinan: Powered by a 6.75-liter twin-turbo V12 engine producing 563 hp and 627 lb-ft of torque, the Cullinan offers effortless performance and a near-silent, ultra-smooth ride. While not focused on outright speed, it delivers plenty of power and refinement. 0-60 mph takes about 5.0 seconds, which is impressive for its size and luxury focus.
• Bentley Bentayga Speed: The W12 engine produces 626 hp and 664 lb-ft of torque, making it quicker and more performance-oriented than the Cullinan. It hits 0-60 mph in about 3.8 seconds.
• Lamborghini Urus: With its 4.0-liter twin-turbo V8 producing 657 hp and 627 lb-ft, the Urus is a performance SUV, clocking 0-60 mph in a blistering 3.2 seconds.
• Mercedes-Maybach GLS 600: The V8 engine produces 550 hp and 538 lb-ft, with a 0-60 mph time of about 4.1 seconds.

While the Cullinan is not the fastest in terms of raw acceleration, its power delivery is exceptionally smooth and refined, which is more in line with Rolls-Royce's focus on comfort and tranquility. The Bentayga Speed and Lamborghini Urus are much quicker, but the Cullinan’s focus is more on effortless power and serenity rather than outright performance.

3. Luxury and Interior

• Rolls-Royce Cullinan: The interior is designed with an obsessive level of attention to detail. You’ll find premium leather, hand-finished wood veneers, real metals, and bespoke touches. The attention to detail is unparalleled, with features like the "The Gallery" (a glass panel that can be used for custom artwork behind the dashboard), a starlight headliner, and bespoke audio systems. Comfort is top-tier, with self-leveling suspension, a whisper-quiet cabin, and a buttery-smooth ride.
• Bentley Bentayga: Also offers a luxurious cabin, with high-quality leather, wood veneers, and advanced technology. It has a more performance-oriented feel compared to the Cullinan, and the interior can be customized, though it doesn't reach the same level of opulence as the Rolls-Royce.
• Lamborghini Urus: The Urus interior is sportier, with a mix of luxury and performance-oriented design. While luxurious, it focuses more on dynamic driving and less on the serene, handcrafted feel that defines the Cullinan.
• Mercedes-Maybach GLS 600: The GLS 600 features an interior rich with leather, wood, and technology. The Maybach edition is more luxurious than the standard GLS, but it still doesn't have the same level of craftsmanship or bespoke feel as the Rolls-Royce.

The Cullinan excels when it comes to bespoke luxury and craftsmanship. Every detail can be tailored to the owner's exact specifications, making it the most personalized option among these SUVs.

4. Technology and Features

• Rolls-Royce Cullinan: While Rolls-Royce does not focus on cutting-edge technology in the same way as some other luxury automakers, the Cullinan offers top-tier amenities such as adaptive cruise control, night vision, advanced infotainment, bespoke audio, and multi-zone climate control. The emphasis is on comfort, peace of mind, and elegance, rather than flashy tech.
• Bentley Bentayga: The Bentayga features a high-tech infotainment system with Apple CarPlay, Android Auto, and advanced navigation. It also offers an off-road mode, which the Cullinan does not prioritize.
• Lamborghini Urus: High-tech features include a large touchscreen interface, a Bang & Olufsen sound system, and advanced driver-assistance technologies. The Urus offers more performance-focused tech, like dynamic drive modes and torque vectoring, which are less prominent in the Cullinan.
• Mercedes-Maybach GLS 600: Features a luxurious MBUX infotainment system, massaging seats, and a Burmester sound system. The Maybach GLS is focused on tech that enhances the rear-passenger experience, with executive seating options, more advanced climate control, and an excellent entertainment system.

The Cullinan is more conservative in its use of technology compared to some competitors, but its focus is on ensuring an elegant, serene experience that appeals to the most discerning buyers.

5. Off-Road Capabilities

• Rolls-Royce Cullinan: While the Cullinan is marketed as an SUV, its off-road capabilities are more about versatility and comfort on various terrains than about extreme off-roading. It is equipped with an advanced air suspension system and all-wheel drive that allows it to handle rough terrain in a composed manner, though it is not built for extreme off-roading.
• Bentley Bentayga: The Bentayga offers multiple drive modes, including a dedicated off-road mode, and is better equipped for rugged terrain than the Cullinan, thanks to its more off-road-oriented setup.
• Lamborghini Urus: The Urus offers an off-road mode for light exploration, but it's not designed to go off-roading in the same way as the Bentayga.
• Mercedes-Maybach GLS 600: Though the Maybach is not designed for serious off-roading, it features a sophisticated air suspension and 4MATIC all-wheel drive system that provides impressive on-road and moderate off-road capabilities.

6. Driving Experience

• Rolls-Royce Cullinan: The Cullinan’s driving experience is all about effortless power, smoothness, and comfort. The suspension system absorbs road imperfections so well that the ride feels as though you’re gliding. The V12 engine provides ample power for cruising without the harshness of sports-oriented vehicles. It's designed to provide a calm, serene experience rather than excitement.
• Bentley Bentayga: More performance-focused, the Bentayga feels sharper, with more precise handling. It balances luxury with dynamic driving, which is more engaging than the Cullinan but not as smooth or serene.
• Lamborghini Urus: The Urus is the most performance-focused, offering high-speed handling, athleticism, and sharp cornering. While luxurious, it is designed to excite and engage drivers more than provide a calm, serene ride.
• Mercedes-Maybach GLS 600: The Maybach GLS is smooth and quiet, prioritizing comfort above all else, though it’s more agile and responsive than the Cullinan.

7. Brand Prestige

• Rolls-Royce: Rolls-Royce is the epitome of luxury, with an unmatched reputation for craftsmanship, refinement, and exclusivity. Owning a Cullinan is about much more than the car itself; it’s about status and the brand’s legacy.
• Bentley: Bentley is a close rival in terms of luxury, but Rolls-Royce holds a slight edge when it comes to exclusivity and prestige.
• Lamborghini: Lamborghini is associated with extreme performance and flair, and the Urus brings that same bold personality to the luxury SUV market.
• Mercedes-Maybach: Maybach offers extreme luxury, but its brand doesn’t carry the same level of heritage and exclusivity as Rolls-Royce.

Conclusion

The Rolls-Royce Cullinan is the gold standard in terms of luxury, craftsmanship, and exclusivity. It doesn’t focus on raw performance, but rather on delivering a tranquil, serene driving experience with a level of detail and opulence that other luxury SUVs can’t match. While vehicles like the Bentley Bentayga, Lamborghini Urus, and Mercedes-Maybach GLS 600 may offer more performance or better technology for the money, none come close to the Cullinan when it comes to pure, unparalleled luxury and prestige.
