The 10 priciest SUVs and trucks to gas up according to Consumer Reports

A large fuel tank and low fuel economy compound each other at the pump, turning a routine fill-up into real sticker shock over a year of driving. Even with gas prices holding relatively steady, these vehicles still empty a wallet fast simply because of how much fuel they burn and how often they need more.

Consumer Reports calculated the cost of a full tank for SUVs and trucks using its own fuel-economy testing paired with national gas prices from AAA, so drivers can see where their money actually goes.

The 2026 Ford $F F-150 starts at $37,290 and runs $79,005 fully loaded, and Consumer Reports calculated a full tank costing $143, higher than every other vehicle in this lineup. CR measured 19 mpg overall, splitting to 13 mpg in the city and 26 mpg on the highway, with a 36-gallon tank that delivers about 485 miles of range per fill-up. Despite that steep fill-up cost, CR ranked this F-150 second out of eight full-sized pickup trucks it tested. That large tank paired with modest highway mileage explains why even a mainstream pickup can cost more to gas up than pricier luxury SUVs in this lineup.

The 2026 Jeep Grand Wagoneer starts at $63,995 and runs $97,310 fully loaded, and Consumer Reports calculated a full tank costing $129. CR measured 18 mpg overall, splitting to 11 mpg in the city and 26 mpg on the highway, with a 26.5-gallon tank that delivers about 465 miles of range per fill-up. CR ranked this Grand Wagoneer 7th out of 9 large SUVs it tested, placing it well behind the category's more fuel-efficient competitors. Its low city mileage in particular stands out as the main driver behind its steep fill-up cost.

The 2026 Mercedes-Benz GLS starts at $90,250 and runs $180,000 fully loaded, and Consumer Reports calculated a full tank costing $128. CR measured 20 mpg overall, splitting to 13 mpg in the city and 30 mpg on the highway, with a 26.4-gallon tank that delivers about 540 miles of range per fill-up. CR ranked this GLS 10th out of 12 luxury three-row SUVs it tested, trailing the majority of its direct competitors on fuel economy. Its strong highway mileage helps stretch that expensive tank of gas further than its city driving numbers would suggest.

The 2026 Toyota $TM Tundra starts at $41,260 and runs $80,800 fully loaded, and Consumer Reports calculated a full tank costing $128. CR measured 17 mpg overall, splitting to 12 mpg in the city and 23 mpg on the highway, with a 32.2-gallon tank that delivers about 540 miles of range per fill-up. CR ranked this Tundra 4th out of 8 full-sized pickup trucks it tested, placing it in the middle of the pack for the category. Its large tank keeps range respectable even though its city and highway mileage both trail the class-leading F-150 Hybrid tested alongside it.

The 2026 Land Rover Discovery starts at $60,200 and runs $83,500 fully loaded, and Consumer Reports calculated a full tank costing $116. CR measured 17 mpg overall, splitting to 12 mpg in the city and 24 mpg on the highway, with a 23.8-gallon tank that delivers about 405 miles of range per fill-up, shorter than any other vehicle in this lineup. CR ranked this Discovery last out of 12 luxury three-row SUVs it tested. That bottom-of-category ranking, paired with the short range per tank here, makes it one of the less fuel-efficient picks in this entire lineup.

The 2026 Land Rover Defender starts at $63,500 and runs $168,700 fully loaded, and Consumer Reports calculated a full tank costing $116. CR measured 18 mpg overall, splitting to 12 mpg in the city and 26 mpg on the highway, with a 23.8-gallon tank that delivers about 435 miles of range per fill-up. CR ranked this Defender last out of 12 luxury midsized SUVs it tested, tied for the bottom spot in its category alongside similarly ranked Land Rover models in this lineup. Its off-road-focused design trades fuel efficiency for capability, and that tradeoff shows clearly in both its ranking and its fill-up cost.

The 2026 Land Rover Range Rover Sport starts at $77,600 and runs $169,500 fully loaded, and Consumer Reports calculated a full tank costing $116. CR measured 20 mpg overall, splitting to 13 mpg in the city and 31 mpg on the highway, with a 23.8-gallon tank that delivers about 480 miles of range per fill-up. CR ranked this Range Rover Sport 11th out of 12 luxury midsized SUVs it tested, ahead of only the Defender in that category. Its strong highway mileage offers some relief, but city driving remains costly given how often the tank needs refilling.

The 2026 Porsche Cayenne starts at $89,900 and runs $214,800 fully loaded, and Consumer Reports calculated a full tank costing $116, tying it with three Land Rover models in this lineup despite ranking far better among them. CR measured 21 mpg overall, splitting to 15 mpg in the city and 29 mpg on the highway, with a 23.8-gallon tank that delivers about 510 miles of range per fill-up. CR ranked this Cayenne 3rd out of 12 luxury midsized SUVs it tested, and that ranking beat every other luxury SUV in this lineup. That higher ranking shows a costly fill-up doesn't always mean poor fuel economy relative to a vehicle's own class.

The 2026 Ford $F F-150 Hybrid starts at $37,290 and runs $79,005 fully loaded, and Consumer Reports calculated a full tank costing $122. CR measured 20 mpg overall, splitting to 15 mpg in the city and 24 mpg on the highway, with a 30.6-gallon tank that delivers about 600 miles of range per fill-up, longer than any other vehicle in this lineup. CR ranked this F-150 Hybrid 1st out of 8 full-sized pickup trucks it tested, the top spot in its category despite still landing on this list. That class-leading efficiency paired with a large tank means fewer stops at the pump even though each fill-up still costs a fair amount.

The 2026 Chevrolet Suburban starts at $63,700 and runs $86,700 fully loaded, and Consumer Reports calculated a full tank costing $111, lower than every other vehicle in this lineup though still a substantial cost. CR measured 16 mpg overall, splitting to 11 mpg in the city and 22 mpg on the highway, with a 28-gallon tank that delivers about 440 miles of range per fill-up. CR ranked this Suburban 2nd out of 9 large SUVs it tested, and that ranking held up well even though it posted a lower overall mpg than every other vehicle in this entire lineup. CR noted the same fuel economy and fill-up costs apply to the mechanically similar GMC Yukon XL.
