18 MPG combined isn’t going to win any fuel economy awards, but nobody buying a 2023 GMC Canyon AT4X with mud-terrain tires is prioritizing trips to the gas station. This is a truck built for off-road adventure, for tackling trails that would leave lesser vehicles stranded. It’s a lifestyle statement as much as a mode of transportation, and that statement says, “I go where I want, regardless of the terrain… or the fuel bill.” The Canyon AT4X buyer understands this trade-off, accepting a lower MPG figure for the capability and rugged charm that this particular model offers.

City and highway performance

Breaking down the EPA numbers, the 2023 GMC Canyon AT4X returns 17 MPG in the city and 20 MPG on the highway. The slightly higher highway figure reflects the 8-speed automatic transmission’s ability to settle into a more efficient cruising gear at higher speeds. City driving, with its constant stop-and-go nature, tends to punish fuel economy, especially in a reliable vehicle as the Canyon AT4X. And, the aggressive tread pattern of mud-terrain tires creates significantly more rolling resistance than all-season tires, further impacting urban fuel consumption. On the open road, that same transmission helps reduce some of that loss.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,450 for the 2023 GMC Canyon AT4X. This calculation assumes 15,000 miles of driving per year, with a mix of city and highway miles, and uses the national average fuel price at the time of calculation. Individual fuel costs will naturally vary based on driving habits, location, and fluctuations in gasoline prices. Someone who primarily uses their Canyon AT4X for weekend off-roading will likely see a higher annual fuel expense, while a driver with a shorter commute might spend less. The $2,450 is an estimate, but provides a valuable point of comparison when evaluating the total cost of ownership.

Real-world expectations

While the EPA figures provide a standardized benchmark, real-world fuel economy often differs. Owners of the 2023 GMC Canyon AT4X frequently report fuel economy figures that are plus or minus 1-2 MPG of the official estimates. Aggressive driving, frequent off-road excursions, and the addition of aftermarket accessories like roof racks or heavier bumpers will all negatively impact fuel economy. On the other hand, those who prioritize smooth acceleration, minimize idling, and maintain proper tire inflation might see slightly better numbers. The key takeaway is that the EPA figures are a guide, not a guarantee, and individual results will vary depending on driving style and usage.

How it compares

Compared to other mid-size trucks with similar off-road aspirations the Canyon AT4X’s fuel economy is within the expected range. A similarly equipped Toyota Tacoma TRD Pro typically achieves around 17 MPG combined, while a Jeep Gladiator Rubicon hovers in the same 17-19 MPG range. The Ford Ranger Raptor, with its more powerful engine, gets around 16MPG combined. A Chevrolet Colorado ZR2 is mechanically similar to the Canyon AT4X and achieves comparable fuel economy making this a fair comparison. These comparisons matter because buyers considering the Canyon AT4X are likely cross-shopping these other off-road-focused trucks. all Gmc fuel economy data shows that other models, like the Sierra 1500, offer different characteristics and different fuel economies for a different lifestyle.

Tips to maximize efficiency

Despite its off-road focus, there are steps you can take to improve the 2023 GMC Canyon AT4X’s fuel economy. Smooth and gradual acceleration is key. Avoid aggressive starts and stops, as these actions consume significantly more fuel than gentle acceleration. The turbocharged 2.7L engine delivers ample torque at lower RPMs, so you don’t need to bury the accelerator to get moving.

Maintain proper tire inflation. The Mud Terrain tires on your Canyon AT4X likely require a different pressure than standard tires. Consult the sticker on the driver’s side doorjamb for the recommended inflation pressure. Underinflated tires increase rolling resistance and reduce fuel economy significantly.

Minimize idling. Excessive idling wastes fuel unnecessarily. If you’re stopped for more than a minute, it’s generally more efficient to turn off the engine. Modern engines are designed to start and stop frequently without causing undue wear.

Consider your driving mode. The Canyon AT4X may offer different driving modes tailored to specific conditions, such as “Normal,” “Tow/Haul,” or “Off-Road.” Selecting the appropriate mode for the situation can help optimize fuel economy. For example, using “Normal” mode on paved roads will generally provide the best fuel efficiency.
