18 MPG combined isn’t going to win any fuel efficiency awards, but for the 2021 GMC Canyon 4WD with its reliable 3.6L V6, it’s a figure most buyers have already factored into the ownership equation. This isn’t a commuter car; it’s a truck designed for hauling, towing, and tackling terrain that would leave lesser vehicles stranded. Its fuel consumption is a secondary concern to capability for its target demographic.

City and highway performance

The EPA estimates the 2021 GMC Canyon 4WD at 16 MPG in the city and 22 MPG on the highway. These figures reflect the reality of stop-and-go traffic and higher speeds, both of which impact fuel consumption. The 3.6L V6, while powerful and smooth, requires more fuel to get the Canyon moving from a standstill, explaining the lower city MPG. On the open road, the eight-speed automatic transmission helps to keep the engine in its optimal rev range, contributing to the slightly better highway number.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2021 GMC Canyon 4WD at $2,450. This is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate. Individual driving habits, local fuel prices, and even tire pressure can all significantly impact your real-world fuel expenses. Drivers who primarily use their Canyon for short trips around town can expect to exceed this figure, while those with longer commutes or more highway miles could potentially see a lower cost.

Real-world expectations

While the EPA provides a standardized test, real-world MPG often deviates. Canyon owners report a mixed bag, often aligning closely with the EPA figures when driving conservatively. However, load the bed with gear, tow a trailer, or engage the four-wheel-drive system regularly, and fuel economy will decrease noticeably. Aggressive driving, frequent short trips, and extended idling can also lower the average MPG significantly. Ultimately, what you get out of the vehicle depends on how you use it.

How it compares

Compared to its competitors, the 2021 GMC Canyon’s fuel economy is fairly typical for a four-wheel-drive mid-size truck with a V6 engine. For example, the Toyota Tacoma 4×4 with its 3.5L V6 achieves an EPA-estimated 18 MPG combined, matching the Canyon. The Nissan Frontier, even with its older powertrain, posts similar numbers. A Ford Ranger 4×4 equipped with the 2.3L EcoBoost turbo engine offers slightly better fuel economy, at around 20 MPG combined. The Jeep Gladiator, known for its off-road prowess, typically lands around 19 MPG combined in its 4×4 configuration. These differences, while present, are often not the primary decision-making factor for buyers in this segment, who prioritize capability and utility over ultimate fuel efficiency.

Tips to maximize efficiency

One simple step is maintaining proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended level, which can be found on the sticker inside the driver’s side doorjamb.

Avoid unnecessary idling. Modern engines are designed to be efficient even at startup. If you anticipate being stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine and restart it when you’re ready to go. This is especially true for the Canyon’s 3.6L V6, which consumes a significant amount of fuel at idle.

Drive smoothly and avoid aggressive acceleration and braking and research all Gmc fuel economy data. The Canyon is not a sports car, and treating it like one will diminish fuel economy. Anticipate traffic flow, gradually accelerate and decelerate, and maintain a steady speed whenever possible. This will help minimize unnecessary fuel consumption.

When possible, avoid using four-wheel drive on paved roads. The 4WD system increases friction and puts extra strain on the engine, which uses more fuel. Only engage four-wheel drive when you need it for traction in slippery conditions or off-road situations. Leaving it in 2WD whenever possible will improve fuel economy.
