Fuel spending varies widely across large SUVs and pickups, and the 2027 EPA ratings put numbers on that spread. This group runs from $3,350 a year for the most frugal entry up to $5,150 for the thirstiest models. Here are twelve vehicles, ordered from the highest annual fuel cost to the lowest.

1. Chevrolet Tahoe: Fuel Bill Leader

Estimated yearly fuel spending for the 6.2L V8 four-wheel-drive Tahoe reaches $5,150, the top figure in this group. Its combined rating is 16 mpg, and the cost figure comes from the 2027 Tahoe fuel cost listing for the 2027 model year.
A Tahoe shopper pricing a household budget should note that the number is tied to the 6.2L V8 and 4WD. Other engines in the lineup are rated separately, so the highest cost applies only to this configuration. The figure covers one year of driving at 15,000 miles, with a 55/45 city and highway split.
2. Chevrolet Suburban: Long-Wheelbase Thirst

The Suburban matches the Tahoe at $5,150 a year, again at 16 mpg with the 6.2L V8 and four-wheel drive. The 2027 Suburban ratings page shows the same estimate for the longer body.
Buyers drawn to the extra cargo room of the Suburban should expect no fuel-cost relief from the larger body in this setup. The figure is scoped to the 6.2L engine, so choosing a different powertrain would change the estimate. Cost comparisons across the list assume 15,000 miles a year.
3. GMC Yukon: Same V8, Same Bill

The GMC Yukon lands on the same $5,150 annual fuel cost and 16 mpg combined, using the 6.2L V8 with 4WD. Details sit in the Yukon 4WD fuel estimate for the 2027 model.
The Yukon shares its drivetrain numbers with its Chevrolet siblings, so the cost gap between the three comes down to price and trim, not fuel. Owners of this configuration should plan on the highest yearly fuel spending in the list. Estimates in this group assume 15,000 miles a year with a 55/45 city and highway split.
4. Cadillac Escalade: Luxury at the Pump

At $5,150 a year and 16 mpg, the Escalade ties the other three General Motors V8 models at the top. The Escalade 2027 fuel data lists the 6.2L V8 four-wheel-drive version.
A luxury badge does not change the pump math here. Anyone considering the Escalade should treat the $5,150 estimate as the baseline for the 6.2L V8 and compare it against lower-cost entries further down. The figure assumes 15,000 miles a year, a standard assumption in these EPA-derived estimates.
5. Infiniti QX80: Premium Appetite

The Infiniti QX80 with four-wheel drive is rated at 17 mpg, which translates to $4,850 in estimated annual fuel cost. The QX80 mileage and cost page carries the 2027 figures.
That puts the QX80 $300 below the General Motors trio and Escalade, a modest edge for a full-size luxury utility. Buyers comparing the two groups can use the gap as a rough yearly saving. The estimate rests on the EPA-derived assumption of 15,000 miles a year, so drivers covering fewer miles would spend proportionally less.
6. Land Rover Defender: Mild Hybrid, Heavy Habits

Land Rover lists the Defender 110 MHEV at 17 mpg, with a $4,850 annual fuel cost. The Defender 110 MHEV rating covers the mild-hybrid version for 2027.
The MHEV label might suggest big savings, yet the estimate matches the QX80 and sits well above most trucks here. Shoppers expecting hybrid-level thrift should read the mpg figure before assuming a lower bill. Like the other figures, it is derived from EPA ratings at 15,000 miles a year.
7. Lincoln Navigator: Big Lincoln, Smaller Tab

The four-wheel-drive Lincoln Navigator carries a $3,950 annual fuel cost at 17 mpg. The Navigator 4WD cost listing records the 2027 estimate.
Despite sharing the 17 mpg rating with the Infiniti and Land Rover above it, the Navigator shows a figure $900 lower. Buyers should check how the estimate is scoped before comparing across brands. Annual costs in this list assume 15,000 miles a year, with a 55/45 city and highway split.
8. Ford Expedition: Full-Size Ford Mid-Pack

Ford’s Expedition with four-wheel drive reaches 18 mpg and a $3,700 yearly fuel cost. That figure appears on the Expedition fuel economy page for 2027.
One more mile per gallon than the Navigator accompanies a $250 lower annual estimate. Owners of the largest Ford utility can read the result as a mid-table cost among full-size SUVs. The calculation uses the same 15,000-mile yearly assumption as every other entry, so the comparison stays like for like.
9. Jeep Grand Wagoneer: Wagoneer Wallet Check

Jeep puts the Grand Wagoneer at 18 mpg in 4WD form, with $3,700 in annual fuel cost. The Grand Wagoneer estimate lists the 2027 numbers.
The result equals the Expedition and the Nissan Frontier that follows. For buyers weighing a large three-row Jeep, the estimate places it in the middle of this ranking. The cost is an EPA-derived estimate based on 15,000 miles a year, not a measured ownership figure.
10. Nissan Frontier: Midsize Pickup Cost

The Nissan Frontier PRO-4X with four-wheel drive is rated at 18 mpg and $3,700 a year in fuel. The Frontier PRO-4X listing supplies the 2027 data.
A midsize pickup matching a full-size Ford and Jeep on yearly cost shows that size alone does not set the bill. Trail-oriented trims such as PRO-4X are the configuration the number applies to. As with the rest of the list, the estimate assumes 15,000 miles a year and a 55/45 city and highway mix.
11. Jeep Gladiator: Open-Air Pickup Bill

The four-wheel-drive Jeep Gladiator is rated at 19 mpg, which brings an estimated annual fuel cost of $3,550. The Gladiator 4WD fuel page shows the 2027 figure.
That is $150 below the Frontier and Jeep’s own Grand Wagoneer. Gladiator buyers get a slightly lighter fuel bill than most entries here while staying inside the group. The figure assumes 15,000 miles of driving a year, so actual spending depends on how far an owner drives.
12. Dodge Durango: Cheapest on the List

At $3,350 a year and 20 mpg, the all-wheel-drive Dodge Durango has the lowest cost on this list. The Durango AWD cost estimate gives the 2027 estimate.
The $1,800 difference from the Tahoe shows how wide the spread is within one list. Durango buyers still land at the low end of this group, not the top of EPA efficiency rankings. That estimate also uses the 15,000-mile yearly assumption, which keeps it comparable with the thirstier V8 models above.
