Some vehicles may look great or offer impressive performance, but when it comes to fuel efficiency, they fall short. In fact, some cars and trucks are notorious for wasting gas and costing drivers a fortune at the pump. In this list, we’ll take a look at the 25 Most Fuel-Wasting Cars Ever to Hit the Road, highlighting the models that guzzle gas and drain your wallet faster than you’d expect.

Hummer H1
The Hummer H1 is notorious for its abysmal fuel efficiency, with only around 10 miles per gallon (MPG). This military-inspired behemoth weighs over 7,000 pounds and is equipped with a massive 6.5-liter diesel engine, making it more suited for off-road adventures than fuel economy. Its sheer size and weight significantly contribute to its gas-guzzling reputation.
Chevrolet Suburban (Early 2000s)
With a large 8.1-liter V8 engine, the early 2000s Chevrolet Suburban was a heavyweight SUV built for power, but not for fuel efficiency. Its fuel economy hovered around 12-15 MPG, and with its massive size and weight, this vehicle was one of the biggest gas guzzlers of its time.
Ford Excursion
Known as one of the largest SUVs ever produced, the Ford Excursion came with a powerful V10 engine, offering poor fuel economy at around 10-12 MPG. Built for heavy-duty towing and hauling, its weight and engine size made it incredibly inefficient for everyday driving.
Lamborghini Aventador
The Lamborghini Aventador may be a high-performance supercar, but it comes with a 6.5-liter V12 engine that achieves around 9-15 MPG. While it delivers incredible speed and performance, it’s notorious for being inefficient due to the amount of fuel needed to power its massive engine.
Bugatti Veyron
The Bugatti Veyron’s 8.0-liter W16 engine and four turbochargers give it jaw-dropping performance, but with a fuel economy as low as 8 MPG in the city, it’s one of the worst offenders when it comes to fuel efficiency. Its hypercar status comes at a significant cost to gas consumption.
Rolls-Royce Phantom
The Rolls-Royce Phantom offers luxury in every aspect, but its large V12 engine and nearly 6,000-pound weight result in an average of 12-14 MPG. This extravagant sedan prioritizes opulence over fuel economy, making it one of the most wasteful luxury cars on the market.
Bentley Mulsanne
With a 6.75-liter twin-turbocharged V8 engine, the Bentley Mulsanne provides plenty of power, but at the cost of fuel efficiency. Its fuel economy of around 10-14 MPG, combined with its opulent design, makes it a prime example of a fuel-wasting luxury vehicle.
Toyota Land Cruiser
While known for its off-road capabilities, the Toyota Land Cruiser’s large V8 engine gives it an average fuel economy of 13-17 MPG. Its size, weight, and power make it one of the least fuel-efficient vehicles in the SUV market, despite its reputation for reliability.
Dodge Ram SRT-10
The Dodge Ram SRT-10 is powered by the same engine found in the Dodge Viper, a massive 8.3-liter V10. With an average of just 9-12 MPG, this performance truck was never built with fuel efficiency in mind. Its focus on speed and power makes it a notorious gas guzzler.
Cadillac Escalade
The Cadillac Escalade has a reputation for being a luxury SUV, but its 6.2-liter V8 engine delivers a mere 14-17 MPG. Designed for power and comfort, the Escalade sacrifices fuel efficiency for its size, making it a poor choice for those concerned about fuel consumption.
Jeep Grand Wagoneer (2022)
The Jeep Grand Wagoneer, with its 6.4-liter V8 engine, offers plenty of power and luxury but comes with a fuel economy of around 13-18 MPG. As a modern large SUV, its poor fuel efficiency puts it among the worst in its class for gas consumption.
Chevrolet Camaro ZL1
The Chevrolet Camaro ZL1 is a muscle car that focuses on performance, with its supercharged 6.2-liter V8 engine generating immense power. However, with an average of just 12-15 MPG, it’s one of the least fuel-efficient muscle cars on the market today.
Mercedes-Benz G-Class (G-Wagon)
The Mercedes-Benz G-Class, particularly the G63 AMG, boasts a twin-turbo V8 engine that delivers around 13-16 MPG. Despite its luxurious design and off-road capabilities, its fuel consumption is notoriously high due to its power and weight.
Aston Martin DB11
The Aston Martin DB11 offers a sleek design and a powerful 5.2-liter V12 engine, but its fuel efficiency hovers around 15-18 MPG. As a high-performance grand tourer, it’s built for speed rather than fuel savings, making it a gas-guzzler on the road.
Nissan Armada
The Nissan Armada’s 5.6-liter V8 engine provides plenty of towing capacity and off-road capability, but it delivers a disappointing fuel economy of 13-18 MPG. Its large size and weight contribute to its fuel inefficiency, especially for daily driving.
Dodge Durango SRT Hellcat
With a supercharged 6.2-liter V8 engine, the Dodge Durango SRT Hellcat is a performance SUV that gets just 12-17 MPG. It delivers incredible power and speed, but its gas consumption is among the highest in its class.
Lincoln Navigator
The Lincoln Navigator may offer luxury and space, but its 3.5-liter twin-turbo V6 engine only provides an average of 16-20 MPG. Despite modern enhancements, its large size and weight contribute to poor fuel economy.
Infiniti QX80
The Infiniti QX80 comes with a 5.6-liter V8 engine that achieves a mere 14-19 MPG. Known for its luxury and size, this SUV is not designed for fuel efficiency, making it a gas guzzler for those who drive it regularly.
Maserati Levante Trofeo
The Maserati Levante Trofeo’s 3.8-liter twin-turbo V8 engine delivers power and speed but only manages about 14-17 MPG. Its focus on performance rather than fuel efficiency makes it one of the more wasteful SUVs on the market.
Range Rover SVAutobiography
The Range Rover SVAutobiography is a luxury SUV with a 5.0-liter supercharged V8 engine that averages around 14-19 MPG. While it offers luxury and off-road capabilities, its fuel efficiency is one of the worst among luxury SUVs.
Ford F-150 Raptor
The Ford F-150 Raptor, with its high-performance 3.5-liter twin-turbo V6 engine, offers power at the expense of fuel economy, averaging around 15-18 MPG. Built for off-road adventures, its efficiency suffers due to its size and capabilities.
BMW X6 M
The BMW X6 M is a high-performance SUV with a twin-turbocharged V8 engine, providing an average of 13-18 MPG. Despite its sporty design, the X6 M’s focus on speed and luxury makes it a wasteful vehicle in terms of fuel consumption.
Ferrari 812 Superfast
The Ferrari 812 Superfast’s 6.5-liter V12 engine gives it top-tier performance, but it only manages around 12-16 MPG. As a high-end supercar, it prioritizes speed and power over fuel efficiency, making it one of the worst offenders in fuel consumption.
GMC Yukon XL Denali
