Everybody is aware that luxury cars are the cars with the worst gas mileage.

Fuel economy is a topic that is often discussed right now. So it seems natural that it’s such a popular topic of discussion, given that record-high gas costs push many people to purchase more fuel-efficient cars.¬†

Cars worse gas mileage

The majority of people aren’t now talking about fuel-inefficient cars, though.¬†While most automakers attempt to make up for their cars’ poor fuel efficiency by including extra unique amenities, you should be prepared to pay over $10,000 more in gasoline costs over the following five years compared to other new cars.

Here are the five cars of 2022 with the worst gas mileage.

Subaru Impreza Sport (25 mpg)

Some people might find it strange that a Subaru starts off this list. The Impreza Sport Wagon, however, holds the record for a small station wagon with the poorest fuel efficiency.

A 2.0-liter boxer four-cylinder engine powers it. Unfortunately, the Impreza only achieves 22 mpg in the city and 30 mpg on the highway when connected to a five-speed manual transmission. 

Subaru Impreza Sport

It has a combined fuel economy rating of 25 mpg as a result. So it might not seem all that horrible. However, the Kia Niro, which has a combined rating of 50 mpg, is its rival on the other side of this bargain. Therefore, purchasing a Subaru reduces fuel economy by 50% compared to a Kia.

BMW M3 (18 mpg)

Contrarily, this shouldn’t be all that shocking. Very few individuals even remotely consider a BMW M car a fuel-efficient alternative. If you were on the fence, this article would persuade you that the 2022 M3 Competition M is not a car to consider if you want to save money on gas.

A 3.0-liter inline six-cylinder twin-turbocharged engine powers the M3. 


It generates a staggering 406 pound-feet of torque and 5093 horsepower. In addition, the M3 Competition achieves a 16 mpg city and 22 mpg highway rating by sending all of its power to all four wheels. 

It receives a combined rating of 18 mpg as a result.

2022 Cadillac CT5-V Blackwing (15 mpg)

No one on this planet considers the Cadillac CT5-V Blackwing a fuel-efficient car. But, unfortunately, we also have bad news if you’re hoping to be pleasantly pleased by a bit more fuel economy than you anticipated.

The 6.2-liter V8 supercharger in the CT5-V Blackwing produces 668 horsepower. Auto lovers adore its availability with a six-speed manual transmission. But it would be best if you undoubtedly accepted your fuel economy fate while buying this car. It gets a pitiful 15 mpg in combined driving thanks to its 13 city and 21 highway mpg ratings.

Rolls Royce Ghost (14 mpg)

Now that we have reached this point, it is safe to say that the owners of these vehicles don’t care about the gas price.¬†Starting prices for the 2022 Rolls Royce Ghost in the US are $398,850.¬†

It’s reasonable to believe that the customers can afford to pay whatever it costs to fill the vehicle when we’re talking about cars that, in many locations, cost as much as a good house. Even yet, it’s entertaining to consider how offensive these numbers are.

Rolls Royce Ghost

A 6.7-liter twin-turbocharged V12 powertrain powers the 2022 Ghost. 

We, regular people, squirm just thinking about how much fuel that statement uses. It can generate up to 664 pound-feet of torque and 563 horsepower. But because it weighs nearly three tonnes, it needs that force. As a result, the Ghost has an average fuel economy of 14 mpg (12 mpg city, 19 mpg highway).

Bugatti Chiron Super Sport (9 mpg)

One of the most expensive cars on the planet also has the lowest fuel economy. So a car with a fuel efficiency rating in the single digits for the 2022 model year almost feels criminal.

It’s also not too far from being against the law. But Bugatti is continuing as long as they can get away with it.

A quad-turbocharged W16 engine powers the Chiron Super Sport, producing an astounding 1,577 horsepower and 1,180 pound-feet of torque. Over 270 miles per hour is its peak speed.

Bugatti Chiron Super Sport - one of the cars with the worst gas mileage

Owning a Chiron will cost an additional $30,000 over five years compared to operating the typical car in 2022. Additionally, it claims that, based on an average yearly mileage of 15,000 miles, driving 25 miles cost $14 and $8,400 in gasoline. 

But let’s face it, no Bugatti clocks up that mileage. You cannot feel pity for Chiron owners at the gas pump, given its introductory price of $3,825,000.


As mentioned above, most of these cars are not bought with daily use in mind. Instead, they are typically high-performance cars. The owners of performance and sports cars know that purchasing them usually entails giving up good fuel economy. Even if these cars have the worst gas mileage, they are bought for their brand name.

Investigating just how awful things can get with fuel economy is still amusing despite this. Our advice: avoid these cars if you’re looking to purchase a typical new car. Still not convinced? We have a good reason to say so.
