18 MPG combined won’t win any fuel economy contests, but it’s the expected fuel consumption for the 2024 GMC Canyon equipped with mud-terrain tires and four-wheel drive. Buyers considering this configuration of the Canyon aren’t prioritizing fuel efficiency; they’re buying a capable off-road machine ready to tackle challenging terrain and project a rugged image. This is a truck for weekend warriors, overlanders, and anyone who values go-anywhere capability over saving money at the pump.

City and highway performance

The EPA estimates the Canyon at 17 MPG in the city and 20 MPG on the highway. The small difference between city and highway figures suggests that factors beyond steady-state cruising impact fuel economy. The Canyon’s weight, the aggressive tread pattern of the mud-terrain tires, and the inherent inefficiencies of a four-wheel-drive system all contribute to decreased fuel efficiency, especially during frequent stop-and-go driving. The 8-speed automatic transmission does its best to keep the engine in its optimal range.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for this version of the Canyon is $2,450. This is calculated assuming 15,000 miles of driving per year and using national average fuel prices. Individual fuel costs will vary depending on local fuel prices, driving habits, and the proportion of city versus highway driving. This estimate provides a benchmark for potential owners to factor into their budget.

Real-world expectations

Real-world fuel economy for the Canyon is likely to vary from the EPA estimates, depending on driving style and conditions. Expect the lower end of the range if you spend time off-road, frequently tow trailers, or drive aggressively. More conservative drivers sticking to paved roads might see figures closer to, or slightly exceeding, the EPA estimates. Mud-terrain tires reduce fuel economy compared to all-season or highway tires, especially at higher speeds due to increased rolling resistance.

How it compares

Compared to competitors, the Canyon’s fuel economy is within the expected range for a mid-size truck with similar off-road capabilities. The Toyota Tacoma TRD Off-Road with four-wheel drive manages around 18 MPG combined, while the Chevrolet Colorado Z71 (essentially the Canyon’s corporate twin) lands in a similar ballpark. A Jeep Gladiator, particularly in Rubicon trim, typically yields fuel economy figures in the 17-19 MPG range. Those seeking better efficiency might consider a rear-wheel-drive version of the Canyon with less aggressive tires, but that configuration sacrifices the off-road capability that defines this model.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The Canyon is not a sports car, and abrupt maneuvers will significantly reduce fuel economy. Gentle acceleration and smooth braking will save fuel and extend the life of your tires and brakes.

Maintain proper tire pressure. Mud-terrain tires require specific tire pressure settings, and many owners air down for off-road excursions. Driving on the street with tires at off-road pressures will negatively impact fuel economy and tire wear. Check the tire pressure regularly and adjust as needed.

Limit idling. Idling consumes fuel without covering any distance. Turn off the engine if you anticipate being stopped for more than a minute or two. Modern engine start-stop systems can also help reduce idling fuel consumption. CANYON MPG across all years can be affected by idling.

Consider your driving routes. Avoid congested areas and routes with frequent stop-and-go traffic when possible. Highway driving generally yields better fuel economy than city driving, so plan your trips accordingly.

Lighten your load. Carrying unnecessary weight increases fuel consumption. Remove any unnecessary items from the bed of the truck or the passenger compartment. Even a few extra hundred pounds can have a noticeable impact on fuel economy over time.
