What a GMC Canyon Actually Returns at the Pump
Ask what a GMC Canyon gets at the pump and you expect one number back. There is no one number. The EPA certifies the current Canyon five different ways, and the spread runs from 16 mpg combined to 20.
What moves it is the drivetrain and the tires underneath the truck. The badge on the tailgate has almost nothing to do with it.
Keep reading below, then schedule a test drive near Katy. Bringing your own numbers to the lot settles this faster than any spec sheet.
A Canyon returns 16 to 20 mpg combined, depending on the build
Five certified figures cover the current Canyon, and 4 mpg separates the best from the worst. The EPA publishes them by drivetrain and tire, so two trims can share one number and one trim can sit alone with its own. Here is the full certified set as the EPA publishes it.
| Configuration | City / highway mpg | Combined mpg |
|---|---|---|
| Canyon 2WD | 19 / 23 | 20 |
| Canyon 4WD | 17 / 22 | 19 |
| Canyon 4WD, mud-terrain tires | 17 / 20 | 18 |
| Canyon AT4X (4WD) | 17 / 17 | 17 |
| Canyon AT4X AEV Edition (4WD) | 16 / 16 | 16 |
Read down that combined column and the pattern is easy to follow. Each step away from a plain 2WD truck costs fuel, and every one of those steps is a hardware choice you make at the order sheet.
What city, highway, and combined mpg actually measure
Combined is not the average of the other two columns. The EPA weights the city figure at 55% and the highway figure at 45%, then harmonically averages them (EPA, 2026). That is why the city number carries more of your real cost than most buyers expect, and why a truck can lose ground on the highway alone and still move its headline figure.
| Term | What it means |
|---|---|
| City mpg | Fuel economy over the EPA’s low-speed, stop-and-go test cycle |
| Highway mpg | Fuel economy over the EPA’s steady, higher-speed test cycle |
| Combined mpg | The city figure weighted 55% and the highway figure weighted 45% |
| Mud-terrain tire | A tire with large tread blocks and deep gaps, built to bite loose ground |
| Properly equipped | One specific build, with the engine, axle, and package the rating was measured on |
Automakers run these tests themselves on a dynamometer. The EPA then audits the submitted data and independently confirms about 15% of the results at its own lab (EPA, 2026).
Every Canyon shares one engine, which is why the badge moves so little
GMC builds the current Canyon around a single engine, the 2.7L TurboMax, rated at 310 horsepower. A Canyon Elevation starts at $38,900 and a Canyon Denali at $53,300, and both pull from that same powertrain.
So the $14,400 between those two trims buys cabin content, wheels, and trim hardware. It does not buy a different engine, and it does not buy a different fuel figure. Once you know the drivetrain and the tire on a given truck, you already know what the window sticker will say.
Two-wheel drive is the most efficient Canyon at 20 mpg combined
It also holds the lineup’s best highway figure at 23 mpg, and its 19 mpg city rating is 2 better than the same truck in four-wheel drive. For a buyer whose week is pavement, that is the cheapest Canyon to run before a single option is added.
A 2WD Canyon is not a light-duty compromise, either. GMC rates a 2.7L TurboMax Crew Cab 2WD with the 3.42 axle to tow up to 7,700 lbs, the same ceiling as the 4WD Crew Cab, on a 13,250-lb GCWR. Plenty of boats and utility trailers on the Gulf Coast sit well inside that figure.
Four-wheel drive costs 1 mpg combined, and mud-terrain tires take 2 more
A 4WD Canyon certifies at 17 city, 22 highway, and 19 combined. Put mud-terrain tires on that same 4WD truck and the EPA rates it 17 city, 20 highway, and 18 combined. Three things explain the drop.
- The extra driveline. A 4WD Canyon carries a transfer case, a front driveshaft, and a front differential that a 2WD truck does not. That is more weight to move and more hardware to turn.
- The tread. Mud-terrain tires use large blocks and deep gaps so they can bite into loose ground. On dry pavement those blocks flex and drag.
- Where the tire penalty lands. City stays at 17 mpg with either tire. The highway column falls from 22 to 20. Steady cruising is where tread drag takes the most.
The AT4X certifies at 17 mpg and the AEV Edition at 16
Both off-road trims post flat numbers, which is the tell. The AT4X is rated 17 city, 17 highway, and 17 combined. The AT4X AEV Edition is rated 16 across all three. Neither one picks up the highway bonus every other Canyon gets.
Towing moves with them. GMC rates the AT4X at 6,000 lbs and the AT4X AEV Edition at 5,500 lbs with the 2.7L TurboMax and a 3.42 axle, against 7,700 lbs for a properly equipped Crew Cab. You give up both numbers on the drive to work, months before you ever put the truck in a rut. That is the trade these trims ask for, and it is worth making only if you go off pavement often enough to use what they add.
Match the Canyon build to the week you actually drive
Start with the city column, because Cypress spends most of its truck miles there. TxDOT and the Texas A&M Transportation Institute logged 185,246 annual hours of vehicle delay on the 8.27-mile FM 1960 stretch between SH 249 and I-45 alone (Texas A&M Transportation Institute, 2025). A Canyon idling in that is living on its 16-to-19 mpg city rating, never its highway one.
Houston-area dealers sold 372,898 new vehicles in the 12 months ending May 2026, and trucks and SUVs made up 80.9% of them (TexAuto Facts, 2026). Most of those trucks will never see mud. Here is how the certified figures line up against a real week.
| Your typical week | The Canyon build that fits | What it is rated to return |
|---|---|---|
| FM 1960 commute, pavement, occasional trailer | Canyon 2WD | 20 mpg combined, tows up to 7,700 lbs properly equipped |
| Wet job sites, gravel, boat ramps | Canyon 4WD on the standard tire | 19 mpg combined, tows up to 7,700 lbs properly equipped |
| Mud, sand, or ruts a few times a month | Canyon 4WD with mud-terrain tires | 18 mpg combined, 20 mpg highway |
| Trail work most weekends | Canyon AT4X | 17 mpg combined, tows up to 6,000 lbs |
| Hardest trails, rock and desert | Canyon AT4X AEV Edition | 16 mpg combined, tows up to 5,500 lbs |
Where to check a Canyon sticker in northwest Houston
A certified figure belongs to one specific truck, so the useful question is which store has that configuration on the ground near you. These are the four stores a northwest Houston Canyon shopper usually weighs, compared on location, the brands each one sells every day, and what that means for a midsize truck buyer.
| Dealer | Where it sits for a northwest Houston buyer | Brands on the lot | What a Canyon shopper gets |
|---|---|---|---|
| Group 1 Buick GMC North | FM 1960 at Jones Road, in northwest Houston | and GMC only | New, used, and certified GMC trucks with GMC service and parts on site |
| Wiesner Buick GMC | Conroe, on I-45 north of Houston | and GMC only | Family-owned and GMC store, farther from Cypress and Jersey Village |
| Big Star Buick GMC | Baytown, on the East Freeway | and GMC only | GMC truck inventory led by the Sierra, across the metro from FM 1960 |
| Mac Haik Chevrolet | Katy Freeway, west Houston | Chevrolet | The Chevrolet Colorado, the same GM midsize truck under a different badge |
| AutoNation | 300-plus stores nationwide, including Houston | Many brands across the network | National online buying and one-price shopping, no single and GMC store |
Frequently asked questions
Does the Canyon Denali get worse gas mileage than the Elevation?
No. Two Canyons with the same drivetrain and the same tires carry the same certified figure, whatever the badge says, so a 4WD Denali and a 4WD Elevation are both rated 17 city, 22 highway, and 19 combined. The AT4X and AT4X AEV Edition are the exceptions, and they get their own records because their hardware and tires differ.
What mpg is the 2025 GMC Canyon rated at?
GM Authority reported the 2025 Canyon 2WD Elevation at 19 city, 23 highway, and 20 combined, and the 2025 4WD Elevation, AT4, and Denali at 17 city, 21 highway, and 19 combined (GM Authority, 2025). The 2025 AT4X was rated 17 mpg across the board and the AT4X AEV Edition 16.
What engine does the GMC Canyon use?
GMC lists the 2.7L TurboMax as the Canyon’s engine, rated at 310 horsepower. Every trim in the current lineup uses it, which is why drivetrain and tires carry the fuel story.
Does the EPA rating include towing a trailer?
No. The EPA figure describes the truck by itself, measured over defined test cycles on a dynamometer, so a loaded trailer will always put you below the certified number. Use the rating to compare builds against each other, then plan your fuel budget around the work you actually do.
What separates the AT4X and the AT4X AEV Edition at the pump?
One mpg in every column: the AT4X is rated 17 city, 17 highway, and 17 combined, and the AEV Edition is rated 16 across all three. Towing separates them too, at 6,000 lbs for the AT4X and 5,500 lbs for the AEV Edition with the 2.7L TurboMax and a 3.42 axle.
Will changing my tires change my Canyon’s mpg?
Yes. The EPA certifies a 4WD Canyon on mud-terrain tires 2 mpg lower on the highway than the same 4WD Canyon on the standard tire, so tread choice alone is worth a full column. Your window sticker keeps showing the figure your truck was certified with, even after you swap.
How much more does a Canyon AT4X cost than an AT4?
The AT4 starts at $45,500 and the AT4X at $57,300, both national starting MSRP before freight, tax, title, license, and fees. The AT4X also takes 2 mpg combined and 1,700 lbs of towing off the AT4’s numbers, so the trail hardware costs you at the pump and the hitch as well as the register.
The Canyon’s number is on the build sheet
There is no single answer to what a Canyon returns, and once you see the certified set, you stop wanting one. Pick 2WD and the EPA says 20 mpg combined. Pick 4WD, then mud-terrain tires, then the AT4X, and you walk that figure down to 19, 18, 17, and finally 16. Each of those steps is worth paying for on the right week and expensive on the wrong one, which is why the truck in the photo online matters less than the specific build sitting on the lot.
