17 MPG combined isn’t going to win any fuel-sipping awards, but for the 2024 GMC Canyon AT4X, it’s a price many buyers are willing to pay. This isn’t a grocery-getter; it’s a purpose-built off-road machine with a powerful engine, aggressive tires, and a suspension designed for tackling challenging terrain. The AT4X buyer prioritizes capability and adventure above all else, and they understand that those attributes come with a fuel economy penalty. This is a truck for enthusiasts willing to sacrifice efficiency for serious performance.

City and highway performance

The EPA estimates the 2024 GMC Canyon AT4X at 17 MPG in the city and 17 MPG on the highway. This parity between city and highway figures is somewhat unusual, and it suggests the truck’s optimal efficiency range is a narrow band of moderate speeds and consistent throttle input. Stop-and-go city driving and high-speed highway cruising both stress the engine and drivetrain, pulling it outside its efficiency sweet spot. The aggressive all-terrain tires, designed for gripping rocks and mud, also contribute to increased rolling resistance, regardless of the driving environment.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 GMC Canyon AT4X at $2,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that fuel prices fluctuate, and your personal mileage may vary significantly. If you drive fewer miles or live in an area with lower fuel costs, your actual annual expense could be less. Conversely, high mileage drivers or those living in areas with high gas prices will likely exceed the $2,600 estimate.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy can vary depending on driving habits, terrain, and weather conditions. Expect that consistent off-road use will pull the MPG figure down, possibly significantly. Towing or hauling heavy loads will also decrease fuel efficiency. Conversely, conservative driving on flat terrain with minimal wind resistance may yield slightly better results than the EPA estimates. Ultimately, drivers should expect to be in the 15-19 MPG range under most normal driving conditions. See all all Gmc fuel economy data. And find all CANYON MPG across all years.

How it compares

The GMC Canyon AT4X directly competes with other off-road-focused mid-size trucks. The Toyota Tacoma TRD Pro, for example, is rated at 18 MPG combined with its V6 engine and automatic transmission. The Ford Ranger Raptor, with its more powerful turbocharged V6, achieves a slightly worse 16 MPG combined. These differences are relatively minor and may not be the deciding factor for buyers in this segment. They are more interested in capability and features than marginal fuel savings. Someone cross-shopping these vehicles likely understands this trade-off. Against non-off-road focused trucks like the Chevy Colorado, the GMC Canyon AT4 manages a fuel economy of 20 MPG combined. However, most AT4X buyers simply wouldn’t consider that model.

Tips to maximize efficiency

Despite its off-road focus, there are ways to improve the fuel economy of your 2024 GMC Canyon AT4X. Maintain proper tire inflation. The aggressive all-terrain tires already create significant rolling resistance and underinflated tires only exacerbate the problem. Regularly check and adjust your tire pressure according to the manufacturer’s recommendations.

Avoid unnecessary idling. The 2.7L turbo engine burns fuel even when the vehicle is stationary. If you anticipate being stopped for more than a minute or two, consider turning off the engine to conserve fuel, which help less gas from being used.

Use cruise control on the highway. Maintaining a consistent speed helps the engine operate more efficiently. Avoid sudden acceleration and braking, as these actions consume more fuel. A smooth, steady driving style is key to maximizing fuel economy, though it may be tough given the Canyon’s character.

Lighten your load. Excess weight puts additional strain on the engine and reduces fuel economy. Remove any unnecessary items from the truck bed and cabin to minimize the vehicle’s weight. A lighter vehicle is inherently more efficient.
