The 10 worst gas-guzzling cars according to the EPA

With a recession looming and gas prices through the roof, it makes sense that many buyers in the market for a car would be eager to get a car with the highest miles per gallon. Also, manufacturers are under pressure to create new cars with minimum carbon emissions. As a result, they make cars with lower fuel consumption, but directly at the expense of performance. Electric cars have proven that cars can be fuel-efficient, yet can hit incredible launch times and quarter-miles. In the performance-defining new hypercar segment, there are entries with various forms of electrification, so there’s hope for the transmission heads.


We’re years away from a clean energy paradise, so manufacturers are still churning out junkies who don’t care about fuel efficiency. After researching EPA data, we’ve brought you a list of the best gas-powered cars with the best fuel economy. Now let’s move to the other end of the spectrum and look at the worst cars in this respect. Not surprisingly, this includes high-performance supercars and luxury rides.

10/10 AMG G 63 – 14 MPG

The Mercedes-Benz G-Wagon is an iconic all-terrain vehicle loved by celebrities and the wealthy few who can afford it. It’s incredibly capable on the road, but its price tag is too expensive to risk a scratch, meaning the dirtiest action it’ll taste most is gravel parking. The AMG version of the G-Wagon is a true hot-rod off-roader with sports car-like acceleration. Gas consumption reflects its price.

Under the hood of the AMG G63 is a gas-powered 4-liter V8 with 577 horsepower and an EPA rating of 14 mpg combined. But no one expects economy from a fast, heavy and boxy SUV.

9/10 Lamborghini Urus – 14 MPG

The Lamborghini Urus is a member of the latest class of high-performance luxury SUVs built by traditional sports car manufacturers. They thought they should give customers what they want. This time, it was a gassy, ​​high-performance status symbol for the wealthy. It returns 14 mpg combined fuel economy, but if you can afford it, you probably won’t care about the fuel economy numbers.

That’s the price you pay for the 650 horsepower from the 4-liter twin-turbo V8 under the hood of the Lamborghini Urus.

8/10 Rolls-Royce Cullinan / Ghost / Phantom – 14 MPG

Like the Urus, the Cullinan is Rolls Royce’s first attempt at a sports utility vehicle. As with any Rolls, the expensive palatial isolation chamber is equipped with unmatched luxury. It delivers superior performance from the powerful and thirsty 6.7-liter V12 shared with the Ghost and Phantom, delivering power and speed on all-terrain, all-season adventures.

The EPA rates the Cullinan and its siblings at 14 mpg combined, while city fuel economy drops to 12 mpg. But that’s the least of concerns for such an expensive box at over 300g.

7/10 Ford Shelby GT500 Mustang – 14 MPG

The Ford Mustang Shelby GT500 sits at the top of the Mustang hierarchy with performance that makes it more of a supercar than a muscle car. Under the hood, the 5.2-liter Supercharged Cross Plane V8 beast puts out 760 ponies, which is more than enough for the GT500 to keep up with the exotic European supercar. But this is only possible with premium fuel, which the Mustang pumps out at high speeds.

You get 12 mpg in city driving, 18 mpg on the highway and 14 mpg combined. But you’ll offset some of the pump fees with what the Shelby GT500 offers in its purchase price versus similar performance supercars.

6/10 Ford GT – 14 MPG

The modern Ford GT pays homage to its glorious GT40 forebear with incredible track performance and a seamless design that seamlessly blends modern with retro. It’s also a great ride off the racetrack, but you’ll have to part with half a million dollars for a copy. While the performance numbers aren’t impressive for the price tag, Ford does get 660 horsepower from its twin-turbo 3.5-liter V6.

It’s the same engine in the F-150, although the truck only makes 400 horsepower. The extra ponies come at the cost of inflated bills at the pump, with the Ford GT rated at 14 mpg combined.

5/10 Bentley Continental GT / Bentayga Speed ​​- 14 MPG

Few grand tourers on the market can handle cross-country road trips better than the Bentley Continental GT. It has beautiful styling, a luxurious cabin and fun handling to make every journey worthwhile. If you can afford its exclusive pricing and transfer pump bills from supercharged engines.

The Continental GT comes with two powertrain options, including the top-of-the-line 6-liter W-12 found in the Bentley Bentayga Speed ​​tuned for 650 horsepower. The EPA rates it at 12 mpg city, 18 mpg highway and 14 mpg combined.

4/10 Ferrari 812 GTS – 13 MPG

The Ferrari 812 GTS has it all, a screaming soundtrack, drama and performance. It’s the last of a dying breed as it features the latest iteration of Ferrari’s naturally aspirated V12 engines. The 6.5-liter behemoth makes 789 horsepower and 530 pound-feet of torque, making the 812 GTS super quick, sending it from zero to 60 mph in 2.8 seconds.

Also, the 812 GTS drains the tank super fast with EPA fuel economy ratings of 12 mpg city, 15 mpg highway and 13 mpg combined. The Competizione model returns slightly better at 14 mpg combined.

3/10 RAM 1500 TRX – 12 MPG

Stellantis introduced the RAM 1500 TRX to compete with the runaway Ford F-150 Raptor. They did a good job seeing as the TRX is the fastest gas truck money can buy, with a 0-60 time of 3.7 seconds. That’s faster than experienced sports cars like the Porsche 718 Cayman GT4. It’s also a surprisingly versatile and unsinkable off-roader thanks to its exceptional suspension and fire-breathing, water-free HEMI V8 under the hood.

You’ll enjoy all kinds of adventures with the RAM 1500 TRX, but be prepared to fill it from a trough. The EPA rates it at 10 mpg city, 14 mpg highway and 12 mpg combined.

2/10 Lamborghini Aventador – 11 MPG

2022 marks the final outing for the Aventador brand, as Lamborghini prepares to ditch an icon that has been positively received everywhere. Car and Driver called it the best Lamborghini, while Motor trend called it the friendliest V12 supercar. After an eleven-year run, it still comes with surprising looks. Its appeal is a roaring naturally aspirated V12 engine with 769 horsepower and 531 lb-ft of torque driving all four wheels.

But for all its glory, it returns one of the worst fuel economy ratings in the single digits. The EPA rates the Lamborghini Aventador at 9 mpg city, 16 mpg highway and 11 mpg combined.

1/10 Bugatti Chrion Pur Sport – 9 MPG

After all, the Bugatti Chiron is the thirstiest of the beasts in the automotive world. But under the hood, we don’t expect anything from the car that boasts an 8-liter 16-cylinder powerplant. With big power comes big fuel bills. It is extreme in every aspect you can think of. It’s like nothing else on the road and runs faster than anyone else. Also, its price blows all its competitors out of the water, as does its gas-guzzling behavior.

At 1,500 horsepower, it will eat any supercar for lunch and dinner, but you’ll need to keep fluids ready and close. The standard Chiron gets just 9 mpg city and 11 mpg, while the Chiron Pur Sport and Super Sport models drop to 8 mpg city and 9 mpg.
