SUVs With the Highest Fuel Consumption
SUVs are beloved for their size, style, and muscle, but with great power comes great trips to the pump. Today’s biggest beasts burn through fuel at shocking rates, making them both status symbols and wallet drainers. Here are the SUVs most notorious for guzzling gas!
Mercedes-Benz G-Class (AMG G-63)
The G-Wagon may ooze celebrity charm and unstoppable off-road bravado, but efficiency isn’t part of the package. With its hulking V-8 and nearly 6,000-pound curb weight, the G-63 lumbers to just around 11 MPG combined. Drivers pay a premium not only for luxury, but also for the privilege of fueling this rolling fortress.
Cadillac Escalade V
Cadillac’s Escalade V cranks extravagance up to 11; however, it also gulps fuel like it’s going out of style. Packing a supercharged 6.2-liter V-8, this monster SUV roars with over 600 horsepower but returns just 13 MPG combined. It’s a prime example of how performance and efficiency rarely drive in the same lane.
Cadillac Escalade (Standard V-8)
Even without the V badge, the regular Escalade isn’t shy about burning through gas. Powered by the same brawny 6.2-liter V-8, it manages a meager 16 MPG combined. The tradeoff? Acres of interior space, commanding road presence, and luxury fit for royalty (though anyone behind the wheel should budget extra for their fuel bill).
Toyota 4Runner
Beloved for its rugged dependability and off-road chops, the Toyota 4Runner is a dinosaur in more ways than one. Its older-school 4.0-liter V-6 delivers proven toughness; sadly, efficiency suffers at just 17 MPG combined. Fans might argue the 4Runner’s reliability outweighs its thirst, but regular stops at the gas station are part of the deal.
Nissan Armada
Big, bold, and built for hauling families or boats, the Nissan Armada packs a mighty 5.6-liter V-8 under its hood. Unfortunately, that muscle comes with a serious drinking problem: 15-16 MPG combined. It may win hearts with its capability and comfort, but drivers soon learn fuel efficiency isn’t one of its strong suits.
Jeep Wrangler Rubicon 392
The Wrangler 392 is Jeep’s ultimate trail toy, boasting a 6.4-liter HEMI V-8 that churns out a thunderous 470 horsepower. All that fun comes at a steep cost, though: just 14 MPG combined. It’s a thrill off-road and on, but don’t expect to venture far without planning extra fuel stops.
Dodge Durango SRT Hellcat
When Dodge dropped the Hellcat engine into the Durango, it created the ultimate family hauler-meets-drag-strip monster. The 710-horsepower V-8 is outrageous… and efficiency is a joke at 13 MPG combined. It’s loud, brash, and hilariously impractical - perfect for those who want their three-row SUV to guzzle gas as fast as it guzzles air.
Ford F-150 Raptor R
Yes, technically a pickup, but the Raptor R lives in the same overpowered, SUV-adjacent lifestyle lane. With its 700-horsepower supercharged V-8, it delivers white-knuckle thrills while returning just 12 MPG combined. Owners enjoy bragging rights and shock value, but they’ll also become familiar faces at gas stations across the country.
Chevrolet Suburban 6.2L V-8
The Suburban is a rolling American institution: massive, practical, and family-friendly. But when equipped with the 6.2-liter V-8, it becomes a certified fuel hog. Drivers can expect just 16 MPG combined, a small number for such a big vehicle. It offers road-trip-ready space, sure, but every mile comes with a fuel penalty.
Ford Expedition Max
Supersized SUVs don’t get much bigger than the Expedition Max, and unsurprisingly, it gulps gas like cool water on a hot day. Its turbocharged 3.5-liter V-6 manages only around 17 MPG combined. Families love the cavernous interior; however, long road trips quickly become reminders that size and efficiency rarely coexist.
GMC Yukon XL Denali
The Yukon XL is basically a Suburban in a different suit, and it drinks just as heavily. With the 6.2-liter V-8 under the hood, owners see around 16 MPG combined. It’s a luxury liner on wheels, and all that comfort and space translates into a fuel budget that rivals a mortgage payment.
Lexus LX 600
Toyota’s luxury behemoth, the LX 600, blends refinement with ruggedness - minus efficiency. Its twin-turbo V-6 manages only about 17 MPG combined, which feels especially stingy in an era of hybrids. The LX has bulletproof reliability and it’s endlessly plush, but every trip is accompanied by a chorus of dollar signs at the pump.
Infiniti QX80
Infiniti’s QX80 is massive, cushy, and unapologetically old-school, yet charm comes with a steep price at the gas station. Its 5.6-liter V-8 guzzles fuel at a combined 15 MPG. It’s spacious and comfortable for big families, but expect to schedule fuel stops as part of your regular weekly errands.
Lincoln Navigator
The Navigator is luxury on wheels, dripping with tech, leather, and presence. Unfortunately, its turbocharged V-6 doesn’t deliver thriftiness, posting just 17 MPG combined. While it pampers passengers like few others, it punishes wallets with every fill-up. This is the SUV for those who prefer first-class comfort over any notion of efficiency.
Land Rover Range Rover
The Range Rover is a status symbol, an icon of wealth and capability. But the gas mileage isn’t nearly as glamorous. Depending on the engine, owners see just 16–18 MPG combined. For those who can afford one, the fuel costs might be an afterthought - but the gas stations certainly won’t forget them.
