Besides the record-high vehicle prices, fuel economy is arguably one of the hottest topics in the automotive industry right now. According to the Environmental Protection Agency, the average 2022 vehicle gets 27mpg combined fuel economy, meaning the eye-watering gas prices we see today are herding more buyers to consider cars with higher ratings than this. As such, it's prudent also to know which inefficient cars from the opposite end of the fuel economy spectrum to avoid.

High-end luxury cars from brands like Bugatti, Bentley, and Rolls-Royce unsurprisingly dominate these rankings, but there's room to argue that anyone who can afford these would probably not be looking to penny-pinch at the pump. However, the current market still features several popular luxury coupes, sedans, and sports cars that return shocking fuel economies well below the EPA average. Read on and find out which cars to steer clear of with today's gas prices.

10 2022 Chrysler 300 - 19mpg

The Chrysler 300 is slowly slipping into obscurity within the less-crowded large four-door sedan class, a segment that now attracts a shrinking number of buyers. The Chrysler 300 is unusual for its segment, with features such as a rear-wheel-drive layout and an optional 363hp 5.7-liter Hemi V-8 engine.

Although the standard 292hp 3.6-liter V-6 engine is not the most economical, the more potent yet gas-guzzling V-8 option is an even worse alternative. The V-8 equipped Chrysler 300 has a disappointing estimated EPA rating of 16/25/19mpg city/highway/combined.

However, the high-performance 471hp 5.0-liter naturally aspirated V-8 makes the LC 500 convertible a no-go at this time. The eight-cylinder Lexus LC 500 convertible returns 15/25/18mpg city/highway/combined, so you'd be digging deep into your wallet to foot the fuel costs.

8 2022 BMW M5 Sedan – 17mpg

The BMW M5 is a four-door phenom with the hardware and athleticism to hold its own on the track or highway. Based on the standard BMW 5-Series, the BMW M5 provides endless thrills thanks to a 600hp twin-turbo V-8 that delivers remarkable acceleration numbers.

Unfortunately, it will cost you a lot at the pump to keep enjoying the exhilarating performance. The BMW M5 has an abysmal EPA-estimated fuel economy rating of 15/21/17mpg city/highway/combined, one of the lowest ratings across the BMW lineup.

7 2022 Audi S8 - 17mpg

The Audi S8 is the most powerful model in the flagship A8 range, available only with a 563hp 4.0-liter V-8 engine. Despite having cylinder deactivation and a mild-hybrid setup, the Audi S8 is surprisingly inefficient, with an EPA-estimated economy rating of 14/23/17mpg city/highway/combined.

What's not impressive? In addition to the hefty price tag, the Porsche 911 Turbo's 573 hp twin-turbocharged 3.7-liter flat-six demands deep pockets. The potent flat-six sees the Porsche 911 Turbo return an EPA-estimated 15/20/17mpg city/highway/combined in fuel economy.

Maserati is not big on blending in, and that's a good thing, considering the full-size luxury Quattroporte Trofeo boldly stands out in a segment comprising heavyweights such as the Mercedes-Benz S-Class, Audi A8, and BMW 7-Series. Currently, the fastest Maserati sedan ever, the Quattroporte Trofeo makes up for what it lacks in convenience and comfort features with its unique performance orientation.

However, Maserati's current lineup is not keen on fuel economy, so it's no surprise that the Quattroporte Trofeo exclusively features an inefficient 580 hp 3.8-liter twin-turbo V-8. According to EPA estimates, the Quattroporte Trofeo has a poor fuel economy rating of 13/20/16mpg city/highway/combined.

Despite the ever-tightening legislation on vehicle emissions, the Dodge Challenger has maintained the muscle car allure that most enthusiasts came to love. News that Dodge will replace the Challenger at the end of 2023 might prompt a temptation to buy one of these beasts, but the current fuel prices might be a stumbling block.

The Dodge Challenger SRT Hellcat Widebody features a thirsty 6.2-liter supercharged V-8 that would make proud the muscle cars from the '60s and '70s. But enjoying the blistering power and acceleration come at a cost, considering the poor fuel economy rated at an EPA-estimated 13/21/15mpg city/highway/combined.

The full-size sedan segment is less competitive than it used to be, but the Dodge Charger still stands out with various personalization, engine, and performance options. No matter what kind of driving experience you're after, whether lunacy or leisure, the Charger can match the personality.

However, you'll be disappointed to know that the supercharged 6.2-liter V-8 under the hood ensures the Dodge Charger SRT Hellcat Widebody draws the line at fuel economy. The EPA-estimated 12/21/15mpg city/highway/combined ratings make this ferocious family sedan an ill-advised choice if you plan to save a buck at the pump.

With the CTS-V model on its way out, Cadillac pins its high-performance hopes on the CT5-V Blackwing, the fastest and most powerful model ever featured in its lineup. Equipped with a 668hp 6.2-liter supercharged V-8, standard six-speed manual transmission, and rear-wheel drive, the CT5-V Blackwing wins against world-beaters like the Mercedes-AMG E63 S, Audi RS7, and BMW M5.

Of course, there is always a trade-off, so the Cadillac CT5-V Blackwing balances its performance by having the poorest fuel economy in the current Cadillac lineup. With EPA-estimated ratings of 13/21/15mpg city/highway/combined, the CT5-V Blackwing's abysmal fuel economy is well into pickup truck territory.

1 2022 Ford Mustang Shelby GT500 - 14mpg

Fifty-five years since the debut of the first Shelby GT500, the current model still carries forth the jaw-dropping force, immense grip, and thrilling sensations that set it apart from other muscle cars. Furthermore, the Mustang Shelby GT500 is not just the best and most expensive Mustang ever; it's also the most powerful road car Ford has ever built.

Ford offers the Mustang Shelby GT500 with a venomous 760hp 5.2-liter supercharged V-8 paired to a seven-speed dual-clutch automatic transmission. The mandatory $2,600 gas guzzler tax is understandable, considering the Mustang Shelby GT500's EPA-estimated fuel economy ratings of 12/18/14mpg city/highway/combined are arguably the worst of any current Ford model.
