23 MPG combined isn’t going to set any records, but it’s a practical compromise for the 2017 GMC Acadia AWD with the 2.5L four-cylinder. This combination targets buyers who need the space and practicality of a mid-size SUV and occasionally require all-wheel drive, but aren’t looking for fast acceleration or the ability to tow heavy loads. They prioritize affordability and using less gas over outright performance.

City and highway performance

The EPA estimates 21 MPG in the city and 25 MPG on the highway. The highway figure might be a pleasant surprise to owners who drive long distances. The 2.5L engine, while not powerful, is surprisingly good at maintaining cruising speeds without too much effort. Plan ahead if you want to pass quickly though. The 21 MPG city figure reflects stop-and-go traffic and the drag of the all-wheel-drive system engaging. However, it’s manageable, and sensible driving habits will help you stay close to that number. This set-up is for those who prioritize efficiency over thrilling performance, so it delivers reasonably on expectations.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 GMC Acadia AWD 2.5L is $1,900. This is based on driving 15,000 miles per year and using national average fuel prices. This is a benchmark for comparing running costs against other vehicles. Your individual fuel costs will vary depending on your driving habits, city versus highway driving, and local fuel prices. Hard acceleration, frequent braking, and long idling times will negatively impact your real-world fuel cost.

Real-world expectations

The EPA provides a valuable baseline, but real-world factors are important. Many drivers report that achieving 23 MPG combined requires effort and a light foot. Expect lower fuel economy during winter, especially in colder climates where the engine works harder and all-wheel drive is used more. Headwinds and hills can also hurt fuel efficiency. However, with smooth acceleration and consistent speeds, hitting or exceeding the EPA estimates is achievable for many owners.

How it compares

The fuel economy of the 2017 GMC Acadia AWD 2.5L is in the middle of the mid-size SUV class. A comparable Honda Pilot with all-wheel drive and its standard V6 engine gets around 22 MPG combined. A Toyota Highlander with all-wheel drive and its V6 engine is rated at a similar 22 MPG combined. The Acadia 2.5L is better than larger SUVs with less efficient powertrains. A Chevrolet Tahoe, for example, with its V8 engine, struggles to reach 18 MPG combined, a difference that means hundreds of dollars in extra fuel costs per year. This is important to the Acadia buyer because they are trading some performance for better fuel efficiency and lower running costs, something that drivers can confirm when checking ACADIA MPG across all years.

Tips to maximize efficiency

The 2.5L engine in this Acadia responds well to gentle acceleration. Avoid flooring the accelerator unless necessary. Accelerating slowly allows the engine to operate more efficiently and saves fuel, especially in city driving.

Proper tire inflation is essential for optimal fuel economy. Check your tire pressure regularly and inflate to the recommended levels on the driver’s side doorjamb. Under-inflated tires increase rolling resistance, which reduces fuel efficiency.

Reduce unnecessary weight inside the vehicle. Extra cargo adds weight, making the engine work harder and use more fuel. Remove items you don’t need from the trunk and cargo area regularly.

Minimize idling, especially during colder months. Modern engines warm up quickly, so there’s no need to let the vehicle idle for long. If you expect to be stopped for more than a minute, turn off the engine to save fuel, if conditions allow.

Use cruise control on the highway to maintain a consistent speed, helping prevent speed changes that reduce fuel efficiency. Setting it to a reasonable speed, a few miles per hour below the speed limit, can further enhance fuel savings. You can find all Gmc fuel economy data on our model pages.
