21 MPG combined is what most 2020 GMC Canyon 4WD 2.5L owners see, and it’s generally considered acceptable. It’s a truck designed for light-duty work and weekend adventures, not ultimate fuel efficiency. Buyers choose this specific configuration, the 4WD 2.5L, often prioritizing capability and a lower initial price over saving gas. They might be looking for a truck bed for occasional hauling, the security of four-wheel drive for winter conditions, and manageable size for navigating city streets where full-size trucks feel too big. Fuel economy is balanced against these more practical needs.

City and highway performance

The EPA estimates the 2020 GMC Canyon 4WD 2.5L gets 19 MPG in the city and 24 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine spends more time idling or accelerating from a standstill. The 2.5L engine needs to work harder in these conditions, which reduces fuel economy. On the other hand, the highway figure represents more consistent driving, allowing the engine to settle into efficient cruising. While 24 MPG isn’t exceptional, it’s a reasonable return for a 4WD truck. The six-speed automatic transmission helps keep the engine in its optimal power band at various speeds. Expect that highway number to drop significantly when towing or hauling cargo.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 GMC Canyon 4WD 2.5L at $2,100. This is calculated based on driving 15,000 miles per year, assuming a specific national average fuel price. This provides a standardized benchmark for comparing the relative fuel expenses of different vehicles. Keep in mind that your actual fuel costs may vary significantly depending on your driving habits, local fuel prices, and the type of driving you do. For example, if you regularly drive in congested city traffic or frequently use the four-wheel-drive system, your annual fuel expenses will likely exceed the EPA estimate.

Real-world expectations

The EPA provides standardized testing, but real-world MPG often differs. Owners of the 2020 GMC Canyon 4WD 2.5L report fuel economy figures that hover around the EPA estimates, with some variation based on driving style and conditions. Aggressive acceleration, frequent short trips, and consistent use of four-wheel drive will negatively impact fuel economy. Gentle acceleration, consistent highway driving at moderate speeds, and proper tire inflation can help drivers achieve figures closer to, or even slightly above, the EPA estimates.

As with any vehicle, consistent maintenance and proactive driving habits are important for optimizing fuel efficiency. Be mindful of the engine’s tendency to work harder under load. Avoid abrupt acceleration, especially when carrying heavy items in the bed or towing a trailer.

How it compares

In the mid-size truck segment, the 2020 GMC Canyon 4WD 2.5L’s fuel economy is about average. A comparable Toyota Tacoma 4×4 with its base 2.7L four-cylinder manages around 20 MPG combined. The Nissan Frontier, with its older powertrain design, typically performs worse, often struggling to reach 19 MPG combined in 4×4 form. Even a Chevrolet Colorado (the Canyon’s corporate cousin) with the same 2.5L engine and 4WD system displays similar fuel economy numbers. V6 options in these trucks offer increased performance, but at the cost of lower fuel economy. The Canyon offers a balance of capability and relative efficiency. For shoppers prioritizing fuel economy, rear-wheel drive versions of these trucks typically offer a slight improvement. Comparing across all years of CANYON MPG reveals a general consistency in economy for this powertrain.

Tips to maximize efficiency

The 2.5L engine in the 2020 GMC Canyon responds well to smooth and deliberate inputs. Avoid aggressive acceleration and hard braking to reduce fuel consumption. Anticipate traffic flow and maintain a steady speed whenever possible. This engine isn’t designed for rapid bursts of speed.

Tire pressure is important for fuel efficiency. Regularly check and maintain the correct tire pressure as specified on the doorjamb sticker. Underinflated tires increase rolling resistance, forcing the engine to work harder. Also, consider the type of tires you’re using. All-terrain tires offer enhanced off-road grip, but typically reduce fuel economy compared to standard highway tires.

Only use four-wheel drive when needed. When engaged, the 4WD system increases drivetrain friction, which lowers fuel economy. Engage four-wheel drive when encountering slippery or challenging road conditions, such as snow, ice, or loose gravel, and disengage it when returning to normal paved surfaces.

Remove any unnecessary weight from the truck bed. Extra cargo adds to the vehicle’s weight, forcing the engine to work harder and consume more fuel. Regularly clear out any items that are not essential to your daily driving. Even small amounts of extra weight can add up and negatively impact fuel economy.
