22 MPG combined isn’t going to win any awards, but for the 2020 GMC Acadia with the 3.6L V6 and front-wheel drive, it’s a reasonable compromise. The Acadia, in this configuration, is the family workhorse, tasked with hauling kids, cargo, and occasionally, towing light loads. Fuel economy, while a consideration, often takes a backseat to interior space and capability for typical Acadia buyers.

City and highway performance

The EPA estimates of 19 MPG in the city and 27 MPG on the highway provide a more detailed picture of the Acadia’s fuel consumption. The city figure reflects the increased fuel demand inherent in stop-and-go driving, and the 3.6L V6, while smooth and responsive, needs a steady flow of fuel to get moving. The highway MPG looks more optimistic, thanks to the Acadia’s nine-speed automatic transmission. This gearbox keeps the engine operating at relatively low RPMs at cruising speed, reducing fuel consumption. This powertrain is a durable and effective design that helps make it a common choice amongst potential buyers. You can view ACADIA MPG across all years on our handy comparison tool.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 GMC Acadia FWD 3.6L at $2,000. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is an estimate, your actual fuel costs may be higher or lower depending on your driving habits, the type of gas you use, and the price of gasoline in your area.

Real-world expectations

While the EPA figures provide a useful benchmark, real-world fuel economy often differs. Acadia owners who primarily drive in congested urban areas can expect to see figures closer to the 19 MPG city estimate, possibly even lower during periods of heavy traffic. Conversely, those who spend more time on open highways may achieve results closer to, or even slightly exceeding, the 27 MPG highway figure. The 9-speed automatic is generally smooth and efficient, but aggressive acceleration will quickly impact MPG.

How it compares

The Acadia’s fuel economy positions it in the middle of its competitive set. The Honda Pilot FWD, for example, achieves a slightly better 23 MPG combined, and the Toyota Highlander FWD typically gets around 24 MPG. The Kia Telluride FWD gets 23 MPG combined and is a top contender in the category. On the other hand, some competitors with larger engines can be less efficient. These marginal differences might be less important to some consumers than other considerations, such as passenger space, cargo volume, or specific features, such as the Acadia’s available towing package.

Tips to maximize efficiency

The Acadia’s 3.6L V6 can be surprisingly fuel-efficient if driven responsibly. Avoid aggressive acceleration and hard braking. Anticipate traffic flow and maintain a steady speed whenever possible. The engine doesn’t benefit significantly from premium fuel, mid-grade gas is sufficient.

Keep your tires properly inflated to the recommended pressure listed on the doorjamb sticker. Under-inflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly, especially as temperatures fluctuate.

Minimize the use of accessories that draw power from the engine, such as air conditioning, especially on short trips. While comfort is important, using only the fan can save a small amount of fuel. Also, avoid idling for extended periods.

Regular maintenance is important for optimal fuel economy. Ensure your Acadia receives timely oil changes, and that the air filter is clean. A dirty air filter restricts airflow to the engine, and any maintenance tasks you avoid can negatively impact fuel efficiency.

Consider removing unnecessary weight from the vehicle. Excess cargo adds to the vehicle’s overall weight, forcing the engine to work harder and consume more fuel. Removing junk from the trunk can make a small but noticeable difference.
