What Gas Mileage Does a GMC Acadia Get in Houston Driving?

The GMC Acadia’s mileage is GMC’s published EPA rating, given as city, highway and combined mpg. The same rating applies to an Acadia driven in Houston or anywhere else, and the combined figure is the one to compare.

For the 2026 Acadia, that combined figure is 21 mpg with AWD and 22 mpg with FWD. Group 1 Buick GMC North sells the new Acadia at 11300 FM 1960 West in Houston.

GMC’s EPA ratings give Houston Acadia drivers three mpg numbers

GMC publishes three EPA figures for the Acadia: city, highway and combined. Combined is the overall estimate, and for the 2026 Acadia AWD it is 21 mpg.

City mpg measures stop-and-go driving, and highway mpg measures steady driving at speed. Combined blends the two, so it is the number to compare across vehicles.

The two Acadia versions read the same on city, at 20 mpg each. The difference shows up on the highway, where the AWD is rated 23 mpg and the FWD 26 mpg. That 3 mpg gap is what moves the combined figure from 21 to 22.

What EPA mpg does each current GMC Acadia trim get?

The Acadia comes in two drive setups, AWD and FWD, and each carries its own EPA rating. Both use a 2.5-liter four-cylinder engine with an 8-speed automatic transmission.

The FWD gives up nothing on city and gains 3 mpg on the highway. Its combined rating of 22 mpg is 1 mpg above the AWD’s 21 mpg.

The Elevation and AT4 are each listed at 328 horsepower. The Elevation is also listed at 326 lb-ft of torque. Those power figures are GMC’s own, and they sit beside the EPA ratings rather than replacing them.

GMC Acadia EPA mpg for the 2026 model year

For the 2026 model year, GMC rates the Acadia FWD at 22 mpg combined, and the AWD at 21 mpg combined.

The 2026 ratings are the figures on the window sticker. The EPA certification record lists the same numbers.

Check the model year before you compare mpg. A 2026 Acadia and an Acadia from another year can carry different ratings, so use the year printed on the car you are looking at.

How do EPA mpg ratings compare across GMC and Buick SUVs in Houston?

Each of the four models carries a published EPA city, highway and combined rating from its maker. The Acadia, Terrain, Enclave and Envision all fall within the same few mpg of each other on combined.

GMC and Buick publish these 2026 EPA ratings:

The GMC Terrain FWD is rated 27 combined, which is 5 mpg more than the Acadia FWD’s 22. If fuel economy is the deciding number, the Terrain is the GMC to compare first.

The Buick Envision AWD is rated 25 combined, 4 mpg above the Acadia AWD. The Buick Enclave is rated 22 combined with FWD, matching the Acadia FWD, and 21 combined with AWD, matching the Acadia AWD.

If the Acadia’s size is what you need, the Acadia is the model to start with.

What do city, highway and combined mpg mean on an Acadia sticker?

EPA sets these figures from lab tests rather than from a road trip. Automakers test a representative vehicle over five defined cycles on a dynamometer, and EPA confirms roughly 15% of results on its own (U.S. Environmental Protection Agency, 2026).

The city cycle represents urban driving, with the engine started cold and the car driven in stop-and-go rush hour traffic. The highway cycle represents a mix of rural and Interstate driving with a warmed-up engine (U.S. DOE/EPA, fueleconomy.gov).

There are five test cycles in all. Three run without heating or air conditioning, and two use climate control: a hot test at 95°F with the cabin cooled, and a cold test at 20°F with heat and defrost on (U.S. EPA, 2026). A summer drive with the air conditioning running is the case the hot test covers.

Combined is weighted 55% city and 45% highway (U.S. Environmental Protection Agency, 2026). So the combined number leans on city driving more than highway driving.
