The 2019 GMC Acadia AWD with the 2.5L 4-cylinder gets 22 MPG combined. This represents a compromise made by some buyers. It’s not class-leading, and it isn’t setting any efficiency benchmarks, but for those needing three rows of seating and available all-wheel drive without wanting the bulk and fuel consumption of a full-size SUV, this Acadia achieves a balance of utility and decent economy.

City and highway performance

The EPA estimates favor highway driving for optimal fuel efficiency. The city MPG is 21, while the highway figure reaches 25. This is not unusual, as the Acadia’s six-speed automatic transmission and relatively small engine benefit from consistent speeds and reduced stop-and-go traffic.

Drivers will likely find that extended periods of low-speed driving, especially with a full load of passengers or cargo, will bring the observed MPG closer to the city estimate, and longer highway trips at a steady pace should yield results near or even slightly above the 25 MPG mark. The difference between city and highway MPG highlights the efficiency limitations of a naturally aspirated four-cylinder engine working to move a fairly heavy vehicle. It performs adequately, but don’t expect miracles.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 GMC Acadia AWD 2.5L at $2,000. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that this is just an estimate and your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and gas prices in your area.

Aggressive driving, frequent short trips in cold weather, and consistent use of premium fuel will all increase your annual fuel expenditure beyond the EPA estimate. Conversely, diligent maintenance and a gentle driving style can help you keep your costs closer to the $2,000 mark.

Real-world expectations

The EPA figures provide a standardized benchmark, but real-world MPG can vary considerably. Drivers who frequently haul cargo or passengers, live in hilly areas, or accelerate quickly will likely see fuel economy below the EPA estimates. However, those who primarily use the Acadia for commuting on flat roads and prioritize fuel efficiency may achieve numbers closer to, or even slightly exceeding, the EPA ratings.

Regular maintenance, including proper tire inflation and timely oil changes, is critical for maintaining optimal fuel economy. The Acadia’s onboard computer provides real-time and average fuel economy data, allowing drivers to monitor their consumption and adjust their driving habits. Smart use of cruise control on the highway can improve fuel economy, but its effectiveness can be offset by frequent use of A/C or accessories.

How it compares

The 2019 GMC Acadia AWD 2.5L competes with other mid-size SUVs with available third-row seating. The Toyota Highlander, for example, gets a higher combined MPG of around 24-25 MPG with its hybrid powertrain, but it costs more initially. The Honda Pilot achieves around 22-23 MPG combined with its V6 engine, offering slightly better performance but using more fuel than the Acadia’s 4-cylinder. Even other trim levels of the Acadia itself offer different MPG ratings, and you can compare ACADIA MPG across all years. The Dodge Durango offers more space and power but sacrifices fuel economy, typically achieving around 19 MPG combined in its V6 configuration.

These comparisons reveal that the Acadia 2.5L AWD asks buyers to accept some performance limitations for better fuel economy than some larger or more powerful competitors, while retaining the three-row utility they need. To see all Gmc fuel economy data will help you make the best choice!

Tips to maximize efficiency

The 2.5L engine has to work harder to move the Acadia’s mass, so smooth and gentle acceleration is key to saving fuel. Avoid sudden bursts of speed and try to anticipate traffic flow to minimize braking. Gradual acceleration allows the engine to operate more efficiently, reducing fuel consumption and maximizing MPG.

Pay attention to your tire pressure and keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Check your tire pressure regularly, especially during changes in temperature, and inflate them to the recommended pressure listed on the driver’s side doorjamb.

Minimize the amount of weight you carry in your Acadia. Extra cargo adds to the vehicle’s overall weight, forcing the engine to work harder and reducing fuel efficiency. Remove any unnecessary items from your vehicle, especially heavy objects, to improve MPG and overall driving performance.

Avoid idling for extended periods. An idling engine consumes fuel without moving the vehicle. If you anticipate stopping for more than a minute, turn off the engine to conserve fuel and reduce emissions. Restarting the engine consumes less fuel than allowing it to idle for a long time. The Acadia does not have auto stop/start, so it defaults to idling when not in motion.
