A Look At The Most Fuel-Hungry Machines On The Road

Cars That’ll Drain Your Tank In No Time

There’s something undeniably intriguing about a vehicle that commands the road with raw power, unmatched luxury, or eye-catching design. But what if these traits come with a voracious appetite for fuel? Some vehicles demand constant refueling and make you wonder if their performance is worth the cost.

Intro

Toyota Land Cruiser

The Toyota Land Cruiser is one of the most recognizable names in off-road vehicles, known for its unmatched reliability and ability to tackle harsh terrains with ease. However, this iconic SUV is infamous for its insatiable thirst for fuel, making it a constant visitor to the gas station.

With 23 mpg for the 326 hp engine, the Land Cruiser is designed to prioritize durability and off-road capability over efficiency. Its heavy-duty frame, massive size, and off-road enhancements like all-wheel-drive systems and locking differentials add significant weight, requiring a large and powerful engine to keep it moving.

Lamborghini Aventador

Built for speed and power, the Lamborghini Aventador doesn’t scream fuel efficiency, with its estimated city at 9 mpg and 16 mpg on the highway. Yet, this doesn’t really bother the Aventador’s lovers, whether they go for the coupe or roadster versions.

The Aventador’s last variant was limited to 600 units, and its engine was claimed to reach a top speed of more than 200 mph with 0 to 60 mph acceleration in 2.8 seconds. This supercar is lightweight yet power-focused and aimed at speed rather than efficiency.

Jeep Grand Cherokee SRT

The Jeep Grand Cherokee SRT stands apart as a performance-oriented SUV that brings the thrill of a muscle car to a family-friendly package. Its high-performance capabilities and aggressive styling are a treat for enthusiasts, but its fuel economy leaves much to be desired.

Just like other Grand Cherokees, it achieves an average consumption of around 20 mpg, with the focus on performance as the primary reason for its poor fuel efficiency. The 6.4L HEMI V8 is designed to deliver rapid acceleration and raw power with little regard for conserving fuel.

Ford Shelby GT500 Mustang

With a top speed of around 180 mph, the Ford Shelby GT500 Mustang is a favorite among enthusiasts who prioritize performance over practicality. But this performance comes with a price, as it leaves the average fuel economy at 12 mpg in the city and 18 mpg on the highway.

Ford Shelby GT500 Mustang (Cont.)

As a muscle car icon, the Ford Shelby GT500 Mustang delivers an exhilarating blend of performance and style. It rockets to 60 mph in less than 3.8 seconds. Nevertheless, the aggressive aerodynamics, wider tires, and reinforced body sacrifice efficiency for adrenaline-pumping speed.

Rolls-Royce Wraith

Want a timeless luxury coupe? Nothing beats the Rolls-Royce Wraith, designed for those who want sophistication and a dynamic driving experience. Production stopped in 2023 due to regulations regarding the car’s aging platform, but it’s still available in the used market as one of the most elegant rides.

Rolls-Royce Wraith (Cont.)

Under the hood of the 2021 model sits a 6.6L twin-turbocharged V12. It accelerates the car to 60 mph in about 4.4 seconds, an impressive feat for a vehicle weighing over 5,200 pounds. The downside? It manages 12 mpg in the city and 18 mpg on the highway.

Toyota Tundra 4WD

If you need a rugged pickup truck, the Toyota Tundra 4WD won’t disappoint you. It’s an excellent choice for heavy-duty tasks with its powerful engine that facilitates towing. However, the fuel economy suffers with an estimated overall EPA rating of 19 mpg, which could be lower in real life.

Toyota Tundra 4WD (Cont.)

Equipped with a 3.4L V6 engine for 389 hp output, the Tundra provides plenty of muscle for off-roading. Nevertheless, fuel efficiency is impacted by its heavy build and strong four-wheel-drive system. It’s still durable, with many owners reporting that vehicles last well beyond 200,000 miles.

Chevrolet Silverado 4WD ZR2

The Chevrolet Silverado 4WD ZR2 is a rugged off-road variant of the popular Silverado pickup truck. Built for adventurers who prioritize capability over efficiency, this truck’s powerful engine and off-road enhancements result in hefty fuel consumption and a little sacrifice in on-road comfort.

With more than 400 hp with the optional V8, the ZR2 Silverado combines the features of a workhorse with advanced off-road features, such as locking front and rear differentials. Nevertheless, the modest 15 mpg fuel efficiency can be a disappointment to those who want to reduce fuel consumption.

Infiniti QX80 4WD

Full-size SUVs bring the best of both worlds, as they offer spacious comfort and premium amenities for family road trips or city cruising. Infiniti QX80 4WD comes with an able 3.5L V6 turbocharged engine that pumps the car to 450 hp for more power on any terrain.

Infiniti QX80 4WD (Cont.)

When it comes to mileage, a combined rating of 17 mpg can be a bit disappointing for such a reliable vehicle. This inefficiency is due to its substantial weight and full-time four-wheel-drive system. While it’s a comfortable ride, the QX80’s thirst for fuel is hard to overlook.

Cadillac CT5-V Blackwing

With only 13 mpg in the city, the Cadillac CT5-V Blackwing might not seem like a fuel-smart choice. But this car is built for luxury as it combines track-ready speed with a refined design. Fitted with the latest Cadillac’s tech and safety features, efficiency takes a backseat.

The 6.2L supercharged V8 engine produces an astounding 668 hp and 659 lb-ft of torque. This power enables the automatic sedan to hit 60 mph in 3.5 seconds. The CT5-V Blackwing is a car built for enthusiasts who value power and handling above all else.

Audi RS Q8

As a luxury performance of the Audi Q8 SUV, the RS masterfully blends practicality with sports car-level speed. Its 631 hp-V8 engine is designed to allow the car to rival many sports cars. However, fuel thirst is a drawback if you want to cut down on your carbon footprint.

While its combination of utility and performance is impressive, the RS Q8 is also known for its appetite for fuel. With a combined efficiency of about 17 mpg, it’s clear that running this car for long drives will take its toll on your budget.

Bentley Continental GT

Despite being offered in different trims, the Bentley Continental GT focuses on offering various luxury levels, you’d naturally expect from this grand tourer. This car is built for long-distance cruising at speeds, and it’s not designed for those who want a car that would consume little gas.

Bentley Continental GT (Cont.)

The fourth generation of the Continental GT was announced in 2024, with a new ultra hybrid performance V8 engine to replace the W12 engine. While the new engine takes less than 3 seconds to hit 60 mph, the estimated efficiency of the 16 mpg engine in the city can make some drivers skeptical.

Rolls-Royce Cullinan

As the first AWD from Rolls-Royce, luxury and performance lovers had a lot to expect from the Cullinan. And they weren’t disappointed with its impressive suspension system that delivers a magic carpet ride. However, the car’s size and weight come with a price.

Rolls-Royce Cullinan (Cont.)

Many experts consider the Cullinan to be one of the most fuel-consuming luxury SUVs. Its twin-turbocharged V12 engine generates 563 hp but delivers a combined fuel efficiency of 14 mpg. However, since Rolls-Royce customers rarely concern themselves with fuel efficiency, the Cullinan still has many fans.

Jeep Grand Cherokee Trackhawk 4WD

The Jeep Grand Cherokee Trackhawk 4WD is a high-octane SUV that offers off-road capability and supercar-like performance. With a supercharged engine borrowed from the Dodge Hellcat lineup, it’s no surprise that the Trackhawk is a gas guzzler of epic proportions.

Given that it’s an SUV, the Jeep Grand Cherokee Trackhawk 4WD delivers a rather modest mpg between 11 and 17. Designed for thrill-seekers, the Trackhawk is equipped with advanced 4WD technology and performance-tuned suspension, which add to its weight and fuel consumption.

Lexus LX570

Revealed in 2008, the Lexus LX570 is a luxury SUV that marries off-road prowess with opulence. Known for its commanding presence and solid capability, it’s also infamous for being one of the thirstiest vehicles in its class, with a 5.7L V8 engine delivering 383 hp.

While an improved powertrain enables the SUV to tow up to 7,000 pounds in the most challenging terrains, it comes at a steep cost to fuel efficiency. With an EPA of about 14 mpg, the LX570 is no friend to frugal drivers due to its hefty weight.

Rolls-Royce Phantom

Most auto lovers would agree that the Rolls-Royce Phantom is the ultimate symbol of prestige. Offering unparalleled comfort and refinement, the combined 14 mpg fuel efficiency isn’t something the avid Phantom lovers would consider, given the car’s remarkably strong engine.

Rolls-Royce Phantom (Cont.)

Combined with the vehicle’s massive size, the 6.7L twin-turbocharged V12 engine, producing 563 hp and 664 lb-ft of torque, is the main culprit for the reduced mileage. Yet, this immense power allows the Phantom to glide effortlessly on long cruises.

Mercedes-Benz G 65 AMG

Although the Mercedes-Benz G 65 AMG’s sales stopped in 2018, this vehicle had its fair share of love. It was designed as the most powerful version of the G-Class, but it was also among the least fuel-efficient vehicles on the road with its 6.0L twin-turbocharged V12 engine.

Mercedes-Benz G 65 AMG (Cont.)

Seeing a V12-powered SUV isn’t very common, and this guaranteed that the G 65 AMG would soon become a favorite among heavy-duty car lovers. The estimated fuel economy would be around 14 mpg, like other AMG models, due to the vehicle’s heavy construction.

Porsche 911 GT3 RS

Achieving between 14 mpg and 18 mpg in fuel consumption proves that the Porsche 911 GT3 RS isn’t designed for budget-conscious buyers. But this makes sense as the track-ready vehicle is designed to achieve astronomical speeds with the turbocharged flat-six engine.

Porsche 911 GT3 RS (Cont.)

This track-focused sports car mixes an iconic design with breathtaking performance. While its naturally aspirated engine is a miracle of engineering, it comes with a hefty appetite for fuel. The car’s lightweight materials and track-tuned suspension are designed for speed, not savings at the pump.

BMW X5 M Competition

Thanks to the 4.4L twin-turbocharged V8 engine, the BMW X5 M Competition can reach 60 mph in about 3.7 seconds. But this high-performance SUV isn’t designed for those who want a car with low running costs as it’s not famous for saving on fuel.

BMW X5 M Competition (Cont.)

Several versions of the BMW X5 M were featured in movies like Get Hard and Fast X to show what an SUV can achieve in terms of power and luxury. However, its sheer performance capability translates into significant fuel consumption with an average combined mpg of 15.

Lamborghini Huracán

The Lamborghini Huracán is a mid-engine supercar offered in coupe or convertible styles as proof of Italian luxury. Designed to thrill, the Huracán’s roaring engine and aerodynamic body demand a steady supply of fuel, enough to power its 5.2L naturally aspirated V10 engine.

Lamborghini Huracán (Cont.)

This car can achieve a fuel consumption of 15 mpg, but it’s a statement car, unapologetically built for driving enthusiasts. Its 631 hp engine emits a distinctive high-pitched roar that, mixed with aggressive aerodynamics, has become synonymous with Lamborghini’s brand identity.

Toyota Sequoia

If you want a car that handles family road trips and rugged adventures, the Toyota Sequoia should be on your radar. While it excels in space and durability, its size and engine make it one of the least fuel-efficient SUVs in its class.

Toyota Sequoia (Cont.)

Under the hood, the Sequoia features a 3.4L V6 hybrid engine that allows some trims to tow more than 9,000 pounds. But it comes at a cost, with fuel economy ratings of 19 mpg in the city and 22 mpg on the highway with the 4WD version.

Dodge Durango SRT Hellcat

The new SRT Dodge Durango Hellcat comes with an improved V8 engine for monstrous performance to earn its place among the most powerful SUVs ever made. However, an average city fuel rating of 12 mpg explains why this car might not be everyone’s cup of tea.

Dodge Durango SRT Hellcat (Cont.)

Coming with a supercharged 6.2L HEMI V8 engine with 645 lb-ft of torque and 710 hp output, the Durango SRT Hellcat can tow up to 8,700 pounds. This is remarkable for a three-row SUV, but its high-performance engine and substantial weight keep fuel efficiency modest.

Bugatti Chiron Pur Sport

Bugatti limited the production of the Chiron Pur Sport to only 60 units. People who go after this powerful hypercar and its luxurious craftsmanship mainly focus on its W16 engine, which produces more than 1400 hp and allows the car to accelerate to 60 mph in less than 2.5 seconds.

Bugatti Chiron Pur Sport (Cont.)

As you might have expected, the Chiron Pur Sport isn’t designed to save on fuel consumption. But still, its 8 mpg in the city and 11 mpg on the highway are unexpectedly low even for hypercars. This is even less efficient than the original Chiron.
