The EPA recently revealed sold in America for 2018, chosen by class. As you can imagine, there are some pretty expensive cars on the list, and many of them are from one manufacturer. It's also a look at how insane vehicle classing is in the US, since a Ferrari GTC4Lusso can be classified as a minicompact. Here they are.
Considering the Chiron is powered by a quad-turbo 8.0-liter W16 making 1500 horsepower, it's no surprise to see it at the top of the EPA's list. At just 11 combined MPG, it's the least-efficient new car you can buy.
Though it's classed as a Minicompact, the GTC4Lusso is not small. It's a full-size GT car with a luxurious cabin and four usable seats. Hiding under that lengthy hood is a 6.3-liter naturally aspirated V12 which, as you can imagine, isn't very good on gas.
Considering the size of the Continental, we're surprised to see it's classed as a subcompact. It must come down to the door count. But no matter where it's classed, 14 MPG isn't very much.
Despite being faster and more powerful than its base counterpart, the Continental Supersports manages to eke out the same combined MPG figure from its 6.0-liter twin-turbo W12.
At over 17 feet long, the Rolls-Royce Dawn is hardly "compact." Despite its class, it puts out the same lackluster 14 MPG as its Bentley competition. Drinking all that fuel is a twin-turbo 6.6-liter V12 making 563 horsepower.
Like its two-door Continental sibling, the four-door Flying Spur makes due with a twin-turbo W12 sending power to all four wheels. The result is the same 14 combined MPG.
While most other cars on this list use 12 or more cylinders, Bentley's most expensive car, the Mulsanne, makes due with a massive 6.75-liter twin-turbocharged V8. No, fuel economy isn't any better because of it.
The Wraith is essentially just a hardtop version of the Rolls-Royce Dawn. How it's classed differently than the dawn, we'll never know. But what we do know is that the two cars share the same powertrain, which means equally bad MPG ratings.
Because the Ghost and Ghost Extended Wheelbase used the same twin-turbo 6.6-liter V12 as the Wraith and the Dawn, they also make the EPA's list. The only real difference is the door count.
The new Phantom uses its own bespoke 6.7-liter twin-turbo V12 making 563 horsepower and 664 lb.-ft. of torque. But despite it being different from the other Rolls-Royce V12, it still gets—you guessed it—14 MPG.
The Volvo V60 Polestar has the smallest and most efficient engine on this list. It's a 2.0-liter inline-four that's supercharged and turbocharged, able to achieve 22 MPG combined.
While most European station wagons never make it to our shores, Mercedes has continually surprised us with US availability for the E63 wagon. The newest one uses a 602-horsepower version of the company's versatile 4.0-liter twin-turbo V8.
