Having a car with good gas mileage used to not really matter (at least as far as cost is concerned.) These days the cost of gas has gotten to a point where how much of the stuff you have to buy every week can really affect your budget. That’s why if you own one of these five new cars with the worst gas mileage, you might want to keep your foot off the right pedal.
The new cars with the worst gas mileage are already pretty absurd
This list of new cars with the worst gas mileage will likely only be owned by folks who don’t even know how much they spend on gas, much less care. Somewhat surprisingly, the car that gets the worst gas mileage aren’t big, giant trucks and SUVs (for the most part), they are almost only sedans and sports cars.
As we know, driving style affects gas mileage a great deal. While there is only so much you can do to mitigate drawing the fuel tank of a V10 supercar, the way you drive can certainly help, even if a little.
The Bentley Continental GT gets absurd gas mileage
The 2021 Bentley Continental has some of the worst gas mileage because it is a 4,773- to 5,370-lb (depending on the configuration) car with a 626-hp twin-turbo 6.0-liter W12 engine. This package lands a horrendous fuel economy of 15 mpg.
The Rolls-Royce Cullinan needs to chill out
If you are starting to notice a trend here, you aren’t wrong. The Rolls-Royce Cullinan is a large SUV that weighs roughly 1 trillion pounds and is powered by 563-hp twin-turbo 6.7-liter V-12 engine for some reason.
Given its weight and dinosaur burning V12, it should come as no surprise that the 2021 Rolls-Royce Cullinan is burning one gallon of fuel every 14 miles. For reference, this is essentially what the steel beasts of the 1950s were getting when fuel cost little more than $0.25 a gallon. The Cullinan isn’t alone. Actually, literally, every Rolls-Royce is getting about the same terrible gas mileage. Rolls-Royce actually makes the most new cars with the worst gas mileage. Who cares? Just pass the caviar.
The 2021 Ford Mustang Shelby GT500 has some of the worst gas mileage
Here is where we get into the sports (muscle) car category. The 2021 Ford Mustang GT500 is a hoot and a half to drive. Although it’s not a huge, billion-pound luxury tank, its massive 760-hp supercharged 5.2-liter V8 engine drinks fuel like it’s getting paid to do it.
There are clever ways to make a car fast; then there is the Ford way. This monster V8 just dumps fuel into the cylinders as liberally as possible. In fact, all that fuel dumping makes this the most powerful Mustang ever manufactured. All that power comes to the tune of $73,095, and that’s before you have to put fuel in it. The 2021 Mustang Shelby GT500 only gets 14 mpg.
The Lamborghini Aventador might suck up your car’s gas if you get too close
Few things are as exciting for car nerds as ripping a Lamborghini down an open road. However, unless you can afford to buy one, you probably can’t afford to even drive one. The 2021 Lamborghini Aventador sucks down an insane 1 gallon of fuel per every 10 miles it drives.
Look behind the driver’s seat, and you’ll find the 730-hp 6.5-liter V12 culprit. This powerplant is truly one of the most satisfying examples in the history of the internal combustion engine. However, it comes with a steep price, both to our wallets and the Earth.
The Bugatti Chiron Pur Sport… As if anyone cares
The Bugatti Chiron Pur Sport came in and beat its own record last year as the new car with the worst gas mileage. Last year, the base model (if there even is such a thing) Bugatti Chiron got 11 mpg. The ramped-up super hypercar, the Bugatti Chiron Pur Sport, has more power, costs more money, and uses more fuel. This monster hypercar landed an abysmal 10 mpg, just like the Aventador.
The 10 mpg comes down to the 1500-hp quad-turbo 8.0-liter W16 engine capable of the highest top speed of any production car. The illusion of this being a consumer article has long been shattered because no one willing to spend $3.6 million on a car cares about how much fuel costs.
