EPA highway estimate: Not rated
The 2020 Ford Transit is spacious and convenient; it’s a dream on wheels for anyone needing to transport goods or people in large quantities. But when it comes to real-world MPG? Not so much. While ticking many boxes for practicality, this monstrous machine tends to tick the box for “gas guzzler” as well. If you’re looking for fuel efficiency, you should steer clear of our friend, the Ford Transit.

2020 Ford F-350 Super Duty: 16 mpg

EPA highway estimate: Not rated
The 2020 Ford F-350 may grant you road royalty, but it will also introduce you to every local gas station attendant. With an MPG more suited for single digits, fuel efficiency isn’t its strong suit. But if you’ve got the payload, it’s got the power. Just be ready for some hefty expenses at the pump.

2017 Ram 2500: 14 mpg

EPA highway estimate: Not rated
The Ram 2500 is a heavy-duty truck designed for hauling. It offers impressive power with a towing capacity of up to 17,980 pounds. The tested four-wheel-drive version features a 410-hp, 6.4-liter V-8 engine, and a six-speed automatic transmission.

However, it only achieves a disappointing 14 mpg during a test. With a thirst for fuel, this truck is for those who crave big, robust vehicles and have their oil well.

The 2018 Toyota Sequoia SR5, with its powerful 5.7-liter V8 engine, may prioritize space and power over fuel efficiency. With EPA ratings of just 13 city and 17 highway MPG, it might not be the best choice if you don’t require towing or off-roading capabilities. Consider exploring more fuel-friendly options for your journey.

The 2017 Ford F-450 Super Duty is a powerful truck with impressive towing capabilities. However, its fuel consumption is exceptionally high, making it less fuel-efficient. It’s an excellent choice for those prioritizing power and performance but could be better for those concerned about fuel economy.

Introducing the 2017 Chevrolet Silverado 3500HD, the “Thirstmaster 3000.” This mighty machine may not be the most fuel-efficient, with a hulking V8 engine and a thirst for gasoline. It averages around 12 MPG, but this could be your perfect road companion if you need heavy-duty towing.

EPA highway estimate: 22 mpg
The Gladiator, with its power and off-road capabilities, is a vehicle that prioritizes performance over fuel efficiency. With a 3.6-liter V6 engine and 285 horsepower, its real-world MPG needs to catch up. However, the Gladiator could be the perfect ride if you crave off-road adventures and raw power.

EPA highway estimate: Not rated
The 2019 Mercedes-Benz Sprinter is a powerful, spacious van that exudes class and functionality. However, its fuel efficiency in real-world conditions leaves much to desire, as it guzzles gas with a fuel economy that can take a toll on your wallet. Despite this, the Sprinter offers a sophisticated and stylish ride that is hard to resist.

EPA highway estimate: 17 mpg
The 2019 Mercedes-Benz G-class is the epitome of luxury but needs to be more fuel-efficient. This high-end vehicle turns heads on the streets but may leave you less impressed at the gas pump.

EPA highway estimate: 14 mpg
The 2017 Mercedes-AMG G63 is a high-performance SUV with a 563 horsepower V8 engine but thirsts for petrol, with a real-world MPG of 13 combined city and highway driving. If you value power and prestige over fuel efficiency, the G63 might be your ride of choice.

However, there may be better options if you prioritize eco-friendliness or saving money. But if you enjoy frequent pit stops and the roar of a hefty engine, the 2017 Mercedes-AMG G63 could be perfect for you!

EPA highway estimate: 14 mpg
Meet the 2021 Ram 1500 TRX, that macho truck that will turn heads on the road without guzzling down gallons of fuel! Its monstrous power is a thrill, but with an average of just 14 miles per gallon, it certainly needs to win awards for fuel economy. If you’re concerned about your carbon footprint or just looking to save at the pump, give this thirsty beast a miss.

2017 Ford F-250 Super Duty: 15 mpg

EPA highway estimate: Not rated
A truck that’s super on duty but less impressive when it comes to real-world MPG. This heavyweight contender boasts rugged charm and Herculean strength, but it’s observed to be a bit of a gas-guzzler, averaging a not-so-green 15 MPG.

It might not be your first pick if you want to save on fuel costs. Who needs fuel efficiency when you can tow a small moon, right?

2020 Chevrolet Silverado 2500 HD: 14 mpg

EPA highway estimate: Not rated
2020 Chevrolet Silverado 2500 HD is a veritable ‘Bigfoot’ of the vehicle world regarding real-world MPG. With its massive size and fuel consumption, this truck is more of an irony on wheels than an efficient commuter. While it has the power to haul your entire house, it can quickly deplete your budget with its thirst for gas.

2020 Ford F-350 Super Duty: 14 mpg

EPA highway estimate: Not rated
A powerful, fuel-hungry beast on wheels. This heavyweight champion offers impressive size, strength, and an insatiable thirst for gasoline. With a real-world MPG that would make a Prius shudder, it’s not an eco-friendly choice.

But this is the ultimate companion if you want to make a statement on the road while carrying a small house in the truck bed.

2017 Ram 2500: 14 mpg

EPA highway estimate: Not rated
2017 Ram 2500, while a dream for off-roaders and heavy haulers, quickly turns into a nightmare at the gas pump. Its mighty 6.7L Cummins turbo diesel engine proves that power comes at a price, and that price is paid in gallons. This hulking behemoth is thirsty, averaging a measly 15 miles per gallon on the highway and an even more dismal 11 MPG in the city.

So, if you’re looking for vehicles with the most real-world MPG, give this gas-guzzling ram a miss.
