Ever-increasing gas prices mean fuel efficiency has become a crucial factor for many car buyers, but not all vehicles prioritize saving gas. Whether it’s due to powerful engines, heavy designs, or outdated technology, some cars and trucks guzzle gas at an alarming rate. For drivers, this means more trips to the pump and higher fuel costs, not to mention a larger environmental footprint.
While fuel economy isn’t always the main selling point for high-performance or luxury vehicles, the following models take poor mileage to a whole new level. If you prefer to avoid spending a fortune on gas, these vehicles might be ones to steer clear of.
Bugatti Chiron Super Sport
If it’s mind-blowing speed you’re after, this Bugatti could be your dream car – but be warned: it’s also a nightmare at the pump. Its 8.0-liter quad-turbocharged W16 engine drinks fuel faster than most can imagine. It delivers less than ten miles per gallon in the city, making it one of the least efficient cars ever built.
Running a Chiron Super Sport requires deep pockets. It’s a stark reminder of what happens when power trumps practicality.
Dodge Durango SRT Hellcat
With a supercharged 6.2-liter V8 lump under its hood, the Dodge Durango SRT Hellcat delivers a massive 710 horsepower – and a thirst for fuel to match. Averaging just 12 miles per gallon in the city, this muscle SUV sacrifices economy for raw power.
Whether hauling cargo or tearing up the road, its performance capabilities are impressive, but the cost of topping up the gas tank is something owners have to contend with.
Ford Shelby GT500
Out on the racetrack, power and speed are what count and fuel consumption isn’t the top priority. That’s why the race-ready Ford Shelby GT500 averages just 12 miles per gallon when cruising city streets. That supercharged 5.2-liter V8 engine gulps down gas like there’s no tomorrow. While its 760 horsepower thrills enthusiasts, drivers who crave the Shelby’s adrenaline rush must also accept its poor fuel efficiency.
Rolls-Royce Phantom
Designed for comfort and exclusivity, the Phantom prioritizes opulence over practicality. This pinnacle of luxury doesn’t deliver when it comes to fuel economy. Its 6.75-liter V12 engine offers effortless power but achieves only around 12 miles per gallon in the city. Owners who can afford this vehicle likely aren’t concerned with gas prices, but its environmental impact is undeniable.
Chevrolet Silverado 2500 HD
For drivers who rely on a vehicle for heavy-duty work, the high fuel costs are often considered a necessary trade-off. The Chevrolet Silverado 2500 HD is a workhorse built for big jobs, but its powerful 6.6-liter V8 engine delivers just 14 miles per gallon. For those who don’t need its full capabilities, the Silverado’s fuel economy might be a reason to look elsewhere.
Lamborghini Aventador
V12 engines tend to guzzle gas – and none more so than the one that powers the Lamborghini Aventador. It’s a car with style and speed, but it comes at a cost, averaging just nine miles per gallon in the city. Even the lightweight carbon-fiber construction can’t offset the thirst of its massive engine.
Toyota Sequoia
One of the least economical SUVs on the market is the Toyota Sequoia – a large SUV with plenty of room for passengers and cargo but offering little in terms of fuel efficiency. The 5.7-liter V8 engine averages just 13 miles per gallon in the city.
Families who need a spacious vehicle will appreciate its reliability, but frequent trips to the gas station can quickly add up.
Jeep Grand Wagoneer
The upscale interior and off-road capabilities of the Grand Wagoneer make it appealing, but its gas-guzzling tendencies are hard to ignore. Powered by a 6.4-liter V8 engine, this luxury SUV averages just 13 miles per gallon. It’s a vehicle designed for indulgence, not saving at the pump.
GMC Yukon XL Denali
If size and power are your priorities, we know a massive SUV that will tick all your boxes. The GMC Yukon XL Denali is designed for comfort and heavy-duty towing, but it has a drawback: just 14 miles per gallon. Blame that big 6.2-liter V8 engine. While its spacious interior makes it a great choice for large families or adventurers, that fuel economy leaves much to be desired.
Mercedes-AMG G63
The boxy design and powerful drivetrain of the Mercedes-AMG G63 means it swallows gas at an alarming rate. Powered by a twin-turbocharged 4.0-liter V8 engine, it achieves just 13 miles per gallon in the city. For those who dream of owning the ultimate luxury SUV, the G63’s poor fuel economy is often overlooked. But the frequent refueling stops may come as a surprise to new owners.
Cadillac Escalade
For buyers who want the premium features and iconic design of the mighty Cadillac Escalade, the trade-off is clear: style comes at the cost of efficiency. This big SUV exudes style and luxury, but its sheer bulk and 6.2-liter V8 engine means that a gallon of gas stretches just 14 miles.
Infiniti QX80
Averaging just 13 miles per gallon, the Infiniti QX80’s is one of the least efficient vehicles in its class. The 5.6-liter V8 engine powers a big SUV body, and frequent visits to the pumps are its downside. Despite its upscale features, the QX80’s poor mileage makes it a tough sell for those prioritizing economy.
RAM 1500 TRX
On the plus side, the RAM 1500 TRX is a powerhouse among trucks, with a supercharged 6.2-liter V8 engine. The bad news is that it consumes fuel like no other – just ten miles per gallon in the city, making it one of the least efficient vehicles on the market. Designed for extreme off-road performance, the TRX sacrifices efficiency for capability.
Aston Martin DBX707
Fancy an SUV that’s capable of 193 mph? The sleek Aston Martin DBX707 isn’t your typical SUV, but its fuel economy is par for the course for a supercar powered by a twin-turbocharged V8 engine. It averages just 15 miles per gallon, putting it among the least economical SUVs.
Nissan Armada
An outdated design and heavy frame contribute to the inefficiency of the Nissan Armada, which averages just 14 miles per gallon in an urban setting. This full-size SUV is powered by a 5.6-liter V8 engine, which offers reliability and a spacious interior, but the Armada’s poor mileage makes it a tough choice for fuel-conscious buyers.
Bentley Bentayga Speed
Luxury with power is combined to perfection in the sumptuous Bentley Bentayga Speed. Its smooth ride is down to a powerful W12 engine, but this performance-focused SUV prioritizes speed over economy – and averages just 12 miles per gallon. Those who crave the ultimate in luxury and performance pay for it at the pumps.
