While SUVs have dominated global roads for decades, moving from practical family haulers to the most popular segment on the market, the inclusion of a 12-cylinder engine remains a rarity. Typically reserved for ultra-luxury limousines or high-performance supercars, these massive engines offer smooth power or raw, aggressive energy that most SUV buyers never seek out.

However, throughout history, a handful of manufacturers have dared to combine massive utility with the complexity of 12-cylinder power. Here are the only five SUVs featuring V12 or W12 engines that were sold new in the United States, ranked by their power output.

1. Lamborghini LM002

The pioneer of the segment, the Lamborghini LM002, was a beast derived from military intentions. Weighing nearly 6,800 pounds, this SUV was equipped with a 5.2-liter V12 engine shared with the iconic Countach. While the original version pushed 444 horsepower, later models specifically adapted for the U.S. market—dubbed the "LM/American"—featured an electronic fuel injection system and produced 414 horsepower. Only 60 of these specific U.S. versions were produced, marking the beginning of the V12 SUV era.

2. Rolls-Royce Cullinan

Arriving for the 2019 model year, the Rolls-Royce Cullinan redefined luxury in the SUV space. Under the hood lies a twin-turbocharged 6.7-liter V12 engine. In standard trim, it delivers 563 horsepower, while the Black Badge variant ups the ante to 592 horsepower and 627 lb-ft of torque. Despite its massive weight of over 6,000 pounds, it can accelerate from 0 to 60 mph in just 4.5 seconds, all while maintaining the signature refinement expected of the brand.

3. Mercedes-Benz G65 AMG

Sharing a spiritual connection to the LM002 due to its utilitarian roots, the Mercedes-AMG G65 took the classic G-Wagon and transformed it into a powerhouse. Between 2012 and 2018, this model featured a 6.0-liter twin-turbocharged V12 producing a staggering 621 horsepower and 738 lb-ft of torque. It remains one of the most eccentric vehicles to ever be sold, combining military-grade boxy aesthetics with excessive 12-cylinder performance.

4. Bentley Bentayga Speed

The Bentley Bentayga is unique in this list for opting for a W12 configuration rather than a traditional V12. This twin-turbocharged 6.0-liter engine became a hallmark of the Bentayga. The high-performance "Speed" variant squeezed 626 horsepower out of the W12, offering immense torque and capability. Although Bentley discontinued the W12 engine after the 2023 model year, it remains the only W12-powered SUV ever sold in the United States.

5. Ferrari Purosangue

The current king of the hill is the Ferrari Purosangue. While Ferrari prefers to label it an "FUV" (Ferrari Utility Vehicle), it is indisputably the most powerful 12-cylinder SUV to hit American showrooms. It utilizes a naturally aspirated 6.5-liter V12, generating an incredible 715 horsepower and 528 lb-ft of torque without the aid of turbochargers or hybrid systems. It stands as a testament to peak internal combustion performance, carrying a price tag that reflects its elite status and performance capabilities.
