22 MPG combined is adequate, not outstanding, for the 2021 GMC Acadia FWD with the 3.6L V6. This SUV is designed for families who want three rows of seating and some upscale features without paying for a true luxury vehicle. Fuel economy isn’t the best in its class but is acceptable for those who value practicality and comfort more than pure efficiency.

City and highway performance

The EPA estimates of 19 MPG in the city and 27 MPG on the highway reflect how the Acadia drives. The V6 engine, while powerful enough in most situations, has to work harder in stop-and-go traffic, which lowers city fuel economy. On the highway, the 9-speed automatic transmission helps keep the engine at its most efficient speed, leading to better highway MPG. Drivers who do most of their driving in cities will probably see fuel consumption closer to the lower end of the EPA’s range.

Annual fuel cost

The EPA estimates the annual fuel cost at $2,000 for the 2021 GMC Acadia FWD 3.6L. This estimate assumes 15,000 miles driven per year and uses national average fuel prices. What you actually spend on fuel will depend on how you drive, local fuel prices, and the type of fuel you buy. While $2,000 isn’t the lowest annual fuel cost in this vehicle class, many Acadia buyers will accept it because of the vehicle’s other qualities.

Real-world expectations

EPA estimates are a useful starting point, but real-world fuel economy often varies. Aggressive driving, heavy loads, and extreme weather can all reduce fuel economy. Owners who drive efficiently and adopt eco-friendly habits may be able to match or beat the EPA estimates. However, those who often carry a full load of passengers and cargo should expect somewhat lower MPG.

How it compares

The 2021 GMC Acadia’s fuel economy compares in different ways to its competitors. The Toyota Highlander FWD with its V6 gets a slightly better 24 MPG combined. Some shoppers might also consider the Honda Pilot, another popular three-row SUV that gets 23 MPG combined in its FWD version. The Ford Explorer, depending on the engine, may offer similar or better fuel economy, especially the hybrid. Those considering all-wheel drive will usually see fuel economy drop by 1-2 MPG, although the ACADIA MPG across all years is readily available to research. These comparisons are important for buyers who are weighing fuel costs against things like price, features, and brand. Those who want to get every last MPG may prefer the Highlander, while others may like the Acadia’s styling and features more and accept the slightly lower fuel economy as the price to pay. For a broad look at the brand, consider all Gmc fuel economy data.

Tips to maximize efficiency

Accelerating gently and avoiding hard braking can really help improve fuel economy. The Acadia’s 3.6L V6 works well with a smooth driving style, which allows the 9-speed transmission to shift efficiently and keep the engine at its best RPM.

Regular maintenance, including keeping tires properly inflated and changing the oil, is critical for good fuel efficiency. Underinflated tires increase rolling resistance, making the engine work harder. Old or dirty engine oil can also reduce engine efficiency and lower MPG.

Cut down on using accessories like air conditioning and climate control as much as possible. These systems use power from the engine, which increases fuel consumption. On nicer days, opening the windows or using the ventilation system can reduce the load on the engine and save fuel.

Take unnecessary weight out of the vehicle. Carrying cargo that you don’t need makes the engine work harder and lowers fuel economy. Cleaning out the Acadia regularly can make a difference, especially if you’re always hauling passengers or cargo.
