With a combined fuel economy of 13 mpg, this high-performance SUV is fun to drive but not fuel-efficient. According to the EPA, its annual fuel cost is $5,340 to $5,352 per year. It's also an old-school SUV. The manufacturer has discontinued just about every other vehicle that once used the same powertrain.

You may have been excited to discover that Ford refreshed the Expedition lineup this year. This large, family-friendly SUV offers a combined 18 mpg, making it a less efficient choice for those concerned with fuel costs. Your family may also not like the ride itself. Reviewers said the Expedition has truckish handling. In addition, some said it looks cheap inside.
3. 2025 Nissan Armada

A full-size SUV with a combined 18 mpg, it's another option for large families but falls short in fuel efficiency. You may find some other reasons not to buy this SUV. Reviewers said there's an occasional jittery ride quality. Plus, the engine may be louder than you desire when idle, and you may not find the space inside as favorable as some competitors.

This luxury SUV offers a combined 17 mpg, highlighting its opulence but poor fuel economy. Per the EPA, this SUV's annual fuel cost is $3,080. The EPA based the number on the assumption of 15,000 miles of driving each year, with 45% done on the highway and 55% on city streets.
5. 2025 Rolls-Royce Cullinan

If you're going to buy a Rolls-Royce, you might have a big enough bank account that you're not too worried about fuel costs. Still, the Cullinan has a combined 14 mpg. Like some others on our list of SUVs with the worst fuel mileage, this one is heavy and big on power. Those are some of the main reasons this one comes with poor fuel economy.
6. 2025 BMW X6 M Competition

Like the GLS600, this performance coupe SUV checks in at a combined 15 mpg. Based on EPA information, you'll likely spend $3,684 per year. That's not all: Like many luxury vehicles with powerful engines, you'll pay more for premium fuel.

This attention-grabbing ride has a combined 14 mpg. Its rugged boxy SUV styling is inspired by the Land Rover Defender, and it boasts a BMW engine. The poor fuel economy is likely due to several factors, including the boxy shape, which lacks aerodynamic qualities, and the weight of over 6,000 pounds.
8. 2025 Cadillac Escalade-V

This supercharged SUV gets a combined 13 mpg, which is not a great way to keep more cash in your wallet. You might think of it as a luxury family ride with a muscle car feel under the hood. However, its power and weight make for poor fuel economy. The EPA estimated that the Escalade-V will likely cost you $4,104 per year in gas.
Bottom line
You might want to consider fuel efficiency if you're looking for a new SUV in 2025. Some of those with the worst fuel mileage could cost you thousands of dollars over the next few years.
In addition to finding a reliable ride to save on car insurance, you could consider looking at similar vehicles from rivals to get the best bang for your buck on the road.
