Is the GMC Acadia good on gas for a family SUV?
Yes. The 2026 GMC Acadia carries an EPA combined rating of 21 mpg with all-wheel drive and 22 mpg with front-wheel drive, the figures the EPA certifies for the window sticker. According to the U.S. Environmental Protection Agency, automakers test a representative vehicle over 5 defined test cycles on a dynamometer, and EPA audits manufacturer data and independently confirms roughly 15% of results at its NVFEL facility (U.S. Environmental Protection Agency, 2026).
Bob Howard Buick GMC sells new GMC Acadias, so an Oklahoma City family can compare the rating with the vehicle on our lot.
What are the Acadia’s EPA mpg ratings by trim and drivetrain?
The EPA ratings for the 2026 Acadia split by drivetrain, and both drivetrains rate 20 mpg in the city.
| Drivetrain | City mpg | Highway mpg | Combined mpg |
|---|---|---|---|
| All-wheel drive | 20 | 23 | 21 |
| Front-wheel drive | 20 | 26 | 22 |
EPA’s combined figure is a weighted average, with City MPG weighted at 55% and Highway MPG at 45% (U.S. Environmental Protection Agency, 2026). The maker lists starting prices of $52,400 for the AT4, $58,900 for the Denali and $63,400 for the Denali Ultimate on the 2026 model year. A family can set each trim’s price beside the drivetrain figures before it chooses.
What does the Acadia cost in gas per month for an Oklahoma City family?
At 21 mpg, an all-wheel drive Acadia uses about 48 gallons per 1,000 miles.
Multiply those gallons by the regular price on the pump to get the monthly cost, and check the number against the price posted that week.
How does the Acadia handle Oklahoma City commutes and highway trips?
The Acadia rates 23 mpg on the highway with all-wheel drive and 26 with front-wheel drive, against 20 in the city for both. Oklahoma City commutes are where that gap shows up in the monthly bill.
Oklahoma City commuters burned 19 extra gallons of fuel each in 2024 just sitting in congestion, 14,394 thousand gallons across the urban area, according to the Texas A&M Transportation Institute’s 2025 Urban Mobility Report (Table 4, 2024 data). A family that spends its week in stop-and-go traffic should use the city rating of 20 mpg for its planning.
Does all-wheel drive cost an Acadia family much more in fuel?
All-wheel drive rates 21 mpg combined and 23 mpg on the highway. City ratings are 20 mpg for both.
On the EPA figures, choosing all-wheel drive costs one mpg combined and three mpg on the highway. Over 2,000 miles, that is about 95 gallons against about 91, so the fuel difference is small. The family decides whether all-wheel drive is worth that gap.
What does the Acadia’s fuel economy mean for three rows of seating?
The 2026 Acadia seats up to seven on the AT4 and Denali and up to eight on the Elevation.
A family that uses row three every day has 23.00 cubic feet of cargo room behind it for groceries, strollers and gear. That is the room to plan around when the seats are full, and it is the figure to weigh next to the 21 to 22 mpg combined rating.

Frequently asked questions
Are GMC Acadias good on gas mileage?
Yes, for a three-row family SUV. The EPA city, highway and combined ratings for all-wheel drive and front-wheel drive are in the table above, so you can match the figures to your own commute and weekend miles before you choose a drivetrain. Because Bob Howard Buick GMC sells new GMC Acadias, you can compare those ratings with the vehicle itself on a test drive.
What is the 2026 GMC Acadia’s combined mpg?
The 2026 GMC Acadia’s EPA combined rating is 21 mpg with all-wheel drive and 22 mpg with front-wheel drive. For an Oklahoma City family, the combined number is the one to multiply by monthly miles.
What engine does the current GMC Acadia use?
The EPA record for the 2026 Acadia lists a 2.5-liter, four-cylinder engine with an 8-speed automatic transmission. The maker lists 328 horsepower for the AT4, Denali, Denali Ultimate and Elevation, and 326 lb-ft of torque for the Elevation.
Why is my GMC Acadia using so much gas?
Most of the time, a high gas bill traces back to where and how the Acadia is driven, not to the rating itself. Stop-and-go driving uses the city rating, so judge your fill-ups against the city figure for your drivetrain in the table above instead of the combined number. The Texas A&M Transportation Institute’s 2025 Urban Mobility Report ties Oklahoma City congestion to extra fuel burned, so a week of heavy traffic will pull your average down. Drivetrain matters on the highway too, because the table shows all-wheel drive rating lower there than front-wheel drive. One caveat: if your mileage stays well below the rating for your drivetrain over several fill-ups, write down your numbers and bring them and your questions to Bob Howard Buick GMC.
