The 2019 GMC Acadia FWD with the 2.5L four-cylinder engine gets an EPA estimated 23 MPG combined. This falls into the “acceptable” range for a mid-size SUV. This vehicle isn’t bought for amazing gas mileage. It appeals to families and individuals who need a practical, comfortable, and relatively affordable SUV, and are willing to sacrifice some MPG for those qualities. Many owners accept the 2.5L’s fuel economy as what it costs to have a versatile vehicle that handles everyday driving situations.

City and highway performance

The EPA estimates the 2019 Acadia 2.5L FWD achieves 21 MPG in the city and 26 MPG on the highway. The city rating reflects how the engine performs in stop-and-go traffic, where the smaller engine works harder to move the Acadia’s weight. However, the highway number is better, suggesting the Acadia maintains reasonably efficient cruising speed once it gets going. This difference highlights the Acadia’s ideal use case: suburban environments with a mix of local driving and longer highway commutes, instead of dense urban areas where fuel economy will be worse.

Annual fuel cost

The EPA says the annual fuel cost for the 2019 GMC Acadia 2.5L FWD is $1,900. This is based on driving 15,000 miles per year, with a specific percentage in the city versus on the highway, and using the national average fuel price at the time. This figure gives a benchmark for comparing the Acadia’s running costs to other vehicles. Of course, individual fuel costs change depending on driving habits, local fuel prices, and the actual number of miles driven annually. For example, someone who mainly drives short distances in the city will likely spend more than the $1,900 estimate.

Real-world expectations

While the EPA estimates create a useful baseline, fuel economy in reality often varies. Acadia 2.5L owners have reported different experiences. Some get numbers close to the EPA estimates, and others fall short, especially in colder climates or with aggressive driving. This variation shows how important it is to consider personal driving habits and environmental conditions when thinking about the Acadia’s expected fuel consumption. Drivers who drive smoothly, maintain consistent speeds, and perform regular maintenance are more likely to achieve the EPA-estimated numbers. Heavy loads and regular use of air conditioning will also hurt fuel economy.

How it compares

The 2019 Acadia’s fuel economy is competitive, but not the best in its class. The Chevrolet Traverse, a related vehicle with a larger V6 engine, gets 18 MPG city and 27 MPG highway in FWD configuration. This illustrates the trade-off between engine power and fuel efficiency. The Toyota Highlander, another popular mid-size SUV, achieves 21 MPG city and 29 MPG highway with its 2.5L four-cylinder engine in LE trim. This difference reflects Toyota’s focus on efficiency, including its engine design. The Ford Explorer, with its base 2.3L EcoBoost engine, offers around 21 MPG city and 28 MPG highway. These comparisons matter to the Acadia buyer because they often compare these vehicles, looking for the best combination of space, features, and fuel economy within their budget. I recommend reviewing ACADIA MPG across all years for greater insight before buying.

Tips to maximize efficiency

Minimize aggressive acceleration and braking. The 2.5L engine in the Acadia needs to work harder to accelerate, mainly from a stop, which hurts fuel consumption. Accelerating smoothly and anticipating stops allows the engine to operate more efficiently.

Keep tires properly inflated. Underinflated tires increase rolling resistance. This forces the engine to work harder, which reduces fuel economy. Check your tire pressure often and inflate to the level recommended on the tire placard.

Reduce extra weight. Carrying extra weight in the Acadia, whether it’s cargo or passengers, increases fuel consumption. Remove any unnecessary items from the vehicle to make it lighter and improve MPG. You can also research all Gmc fuel economy data.

Use cruise control on the highway. Maintaining a consistent speed on the highway helps optimize fuel economy. Cruise control prevents unintended acceleration and deceleration. This leads to smoother and more efficient driving.

Consider using premium fuel only under heavy load. The owner’s manual does not require it, but higher octane gasoline can help prevent pre-detonation when the engine is under heavy load, such as towing a trailer. Pre-detonation would cause the engine control unit to dial back timing and cost you fuel economy.
