2026 GMC Canyon 4WD: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 2026 GMC Canyon 4WD. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Fuel economy at a glance

These are the EPA's official ratings for the 2026 GMC Canyon 4WD. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 2026 GMC Canyon 4WD compares

The 2026 GMC Canyon 4WD returns 19 combined MPG. Cars in the Standard Pickup Trucks 4WD class for the same model year average 41.6 MPG, which puts this car behind the class average by about 54%.

The most efficient car in the Standard Pickup Trucks 4WD class for the 2026 model year is the Rivian R1T Dual Max (22in) at 87 MPG. The bar chart below puts the GMC Canyon 4WD alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2026 model year (across all classes) returns 45.5 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2026 model year is on its own page.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for regular gasoline, which is $3.99/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 789.5 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the GMC Canyon 4WD

The EPA has rated the GMC Canyon 4WD across 21 model years, from 2004 GMC Canyon 4WD through 2026 GMC Canyon 4WD. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

Combined MPG has stayed in roughly the same range across the run. The peak rating came with the 2016 GMC Canyon 4WD at 23 MPG.

Specifications

The 2026 GMC Canyon 4WD runs a 2.7-liter 4-cylinder turbocharged engine paired with a automatic 8-spd, sending power through 4-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

• How much does it cost to fuel a 2026 GMC Canyon 4WD per year?

  The EPA estimates an annual fuel cost of $3,150 for the 2026 GMC Canyon 4WD. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade.
• What fuel does the 2026 GMC Canyon 4WD use?

  The EPA lists the 2026 GMC Canyon 4WD as running on regular gasoline. Using a different grade than the manufacturer specifies can affect fuel economy and engine longevity.
• Has the GMC Canyon 4WD become more fuel efficient over time?

  Combined MPG has stayed close to flat across the run. Both the earliest (2004 GMC Canyon 4WD, 19 MPG) and most recent (2026 GMC Canyon 4WD, 19 MPG) versions sit in the same range.
• How much CO₂ does the 2026 GMC Canyon 4WD emit?

  Tailpipe CO₂ emissions are 462 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 6,930 kilograms of CO₂.
• What is the difference between the city and highway MPG of the 2026 GMC Canyon 4WD?

  City driving returns 17 MPG and highway driving returns 22 MPG, a gap of 5 MPG. The two figures are close enough that the car will hold its rated efficiency well across most driving patterns.
• What engine is in the 2026 GMC Canyon 4WD?

  The 2026 GMC Canyon 4WD has a 2.7-liter 4-cylinder turbocharged engine (EPA description: SIDI). Smaller turbocharged engines like this one tend to deliver bigger-engine power on demand while keeping fuel economy closer to a non-turbo version of the same displacement.
