The 2026 gas mileage rankings reveal a surprising mix of vehicles that are not exactly fuel-efficient. While it's no secret that big trucks and SUVs tend to guzzle gas, the list also includes some high-end and exotic cars that might not be what you'd expect. Here's a breakdown of the worst offenders, along with some insights into why these vehicles struggle to get good gas mileage.
The Gas Guzzlers
BMW X5 M Competition and X6 M Competition: These powerful SUVs are known for their speed and modern features, but their gas mileage is a different story. With a combined 15 mpg, these vehicles are a gas-guzzling duo that might not be the most environmentally friendly choice. Personally, I find it interesting that BMW, a brand often associated with efficiency and luxury, has such a significant gas mileage issue with these models. Perhaps it's a trade-off for the thrill of acceleration.
Mercedes-Maybach GLS600: Comfort and opulence are the names of the game for this SUV, but fuel efficiency takes a backseat. With a combined 15 mpg, it's clear that this vehicle is more about the experience than environmental consciousness. What's fascinating is how the reclining seats and luxurious amenities might distract drivers from the gas pump, making it an even more surprising entry on this list.
Mercedes-AMG G63: Once the king of gas guzzlers, the G63 has seen an improvement with its mild hybrid system. Still, with a combined 15 mpg, it's not exactly a fuel-efficient choice. The G63's power and prestige might be worth the fuel costs for some, but it's a reminder that even high-end vehicles can have their drawbacks.
All gas-powered Rolls-Royce vehicles: Rolls-Royce, the epitome of luxury, takes the cake for the worst gas mileage with a combined 14 mpg. The V12 engine, while powerful, is a gas-thirsty beast. What makes this particularly interesting is the disconnect between the brand's image and its environmental impact. Rolls-Royce owners might not be concerned about gas prices, but it's a point of contention for those who value sustainability.
Dodge Durango Hellcat: Another Hellcat-powered vehicle, the Durango, is a 7-seater powerhouse. With a combined 13 mpg, it's a trade-off between power and efficiency. The Durango's performance might be its selling point, but it's a reminder that high-performance vehicles often come with a price (both literally and figuratively) when it comes to gas mileage.
Cadillac Escalade V: The Escalade, a popular luxury SUV, features a supercharged 6.2-liter engine, resulting in a combined 13 mpg. It's a testament to the idea that luxury and power often come at a cost, both financially and environmentally. What's intriguing is how Cadillac, a brand known for its American heritage, navigates the balance between performance and fuel efficiency.
Ferrari Purosangue: Ferrari's first-ever SUV is a bold move, and its gas mileage reflects that. With a combined 12 mpg, it's a vehicle that might appeal to those who prioritize performance over fuel economy. What makes this fascinating is the brand's shift towards SUVs, challenging the traditional sports car image.
Ford Mustang GTD: The GTD is a road-legal racecar based on the GT3 model, built for speed rather than efficiency. With a combined 12 mpg, it's a reminder that some vehicles are designed for the track, not the daily commute. The Mustang GTD is a testament to the idea that performance and practicality don't always align.
RAM 1500 TRX: A 3-ton truck with a Hellcat engine, the TRX is a powerhouse on and off the road. With a combined 12 mpg, it's expected that towing power comes with a price. The TRX is a vehicle that showcases the trade-off between raw power and fuel efficiency, especially when towing.
Ford F-150 Raptor R: The Raptor R, a supercharged V8-powered pickup truck, offers better gas mileage than its racecar counterpart. With a combined 12 mpg, it's a balance between performance and efficiency. The Raptor R is a perfect example of how high-performance trucks can be both thrilling to drive and relatively fuel-efficient.
The Takeaway
These rankings highlight the diverse reasons why certain vehicles struggle with gas mileage. From powerful engines to luxurious amenities, each car on this list has its own unique story. What's clear is that fuel efficiency is a complex issue, and there's no one-size-fits-all solution. As consumers, it's essential to consider not only the performance and comfort of a vehicle but also its environmental impact. Perhaps it's time for manufacturers to reconsider their priorities and offer more fuel-efficient options without compromising on power and style.
