24 MPG combined is a respectable figure for the 2021 GMC Acadia AWD with its 2.0L turbocharged engine. This is a mid-size SUV with all-wheel drive, so buyers aren’t necessarily prioritizing Prius-level economy, but rather a balance of space, capability, and reasonable running costs. This configuration targets families needing three rows occasionally, who also value a bit of extra traction for bad weather and are willing to trade ultimate V6 power for improved fuel efficiency.

City and highway performance

The EPA estimates 22 MPG in the city and 27 MPG on the highway. These numbers reflect the characteristics of the 2.0L turbo and 9-speed automatic transmission. The city figure is adequate although perhaps not class-leading, reflecting the Acadia’s weight and the stop-and-go conditions where turbo engines can sometimes lag if not driven smoothly. The 27 MPG highway rating is more impressive; the 9-speed transmission allows for relaxed cruising at lower RPMs, which helps maximize fuel efficiency on longer trips. Drivers consistently traveling long distances can expect to come close to this figure, provided they avoid aggressive acceleration.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 GMC Acadia AWD 2.0L to be exactly $1,800. This calculation is based on driving 15,000 miles per year, using a blend of city and highway driving, and factoring in the national average fuel price at the time of testing. While individual fuel costs will vary depending on local gas prices and driving habits, this $1,800 figure provides a standardized benchmark for comparing the Acadia’s running expenses to other vehicles in its class. It is a critical data point for potential buyers as they consider the total cost of ownership beyond the initial purchase price.

Real-world expectations

While EPA figures provide a useful baseline, real-world fuel economy always varies. Expect to see numbers within a few MPG of EPA estimates. Factors like driving style, terrain, traffic conditions, and even tire pressure can influence fuel consumption. Aggressive acceleration and hard braking will quickly diminish fuel economy, and consistently driving in congested city environments will do the same. Maintaining proper tire inflation and keeping up with scheduled maintenance are essential for achieving optimal efficiency. Owners who prioritize smooth, consistent driving habits should expect to get closer to the EPA estimates, while those with a heavier foot may see slightly lower numbers.

How it compares

The Acadia in its AWD 2.0L configuration competes against a host of mid-size SUVs. The Ford Explorer with its 2.3L EcoBoost engine and AWD achieves around 23 MPG combined. The Toyota Highlander Hybrid manages significantly better economy, nearing 35 MPG combined, but comes at a higher price point; buyers need to value fuel efficiency above almost all else to make that jump. The Honda Pilot, typically equipped with a V6, hovers around 22 MPG with AWD, making the Acadia a slightly better choice for fuel-conscious buyers not needing the V6’s extra power. Even within the GMC lineup, shoppers may cross-shop against other trims; see ACADIA MPG across all years to compare. Potential buyers need to weigh these differing fuel economies against their individual needs for space, power, and budget.

Tips to maximize efficiency

The 2.0L turbo engine in the Acadia responds well to a light foot. Avoid aggressive acceleration and try to maintain a smooth, consistent speed. This will help prevent the turbo from spooling up unnecessarily, conserving fuel in the process.

Use the Acadia’s cruise control system on highway drives. Maintaining a constant speed is more fuel efficient than constantly adjusting your throttle, especially on relatively flat terrain. Avoid using cruise control in hilly areas, however, as the transmission may downshift frequently, negating some of the benefit.

Proper tire inflation is important for optimal fuel economy. Check your tires regularly and inflate them to the recommended pressure listed on the doorjamb sticker. Underinflated tires increase rolling resistance, which reduces fuel efficiency.

Minimize the use of accessories that draw power from the engine, such as air conditioning. While A/C is essential in hot weather, use it judiciously. Whenever possible, roll down the windows or use the ventilation system instead. The AWD system also makes a slight economy penalty, check all GMC fuel economy data to see if a FWD variant suits your needs.

Regular maintenance is key to keeping your Acadia running efficiently. Ensure that you follow the recommended maintenance schedule for oil changes, air filter replacements, and other services. A well-maintained engine will always deliver better fuel economy than one that is neglected.
