22 MPG combined is not the main reason someone buys a 2023 GMC Acadia FWD with the 3.6L V6. This mid-size SUV, which competes in a fiercely contested segment, prioritizes space, comfort, and competent road manners over outright fuel efficiency. The Acadia buyer needs three rows, appreciates a comfortable ride, and wants a touch of upscale styling. They accept the fuel economy trade-off for these attributes.

City and highway performance

The EPA estimates place the Acadia’s city fuel economy at 19 MPG and highway fuel economy at 27 MPG. The 19 MPG figure in the city reflects the stop-and-go driving that penalizes larger vehicles, while the 27 MPG highway rating is more respectable, thanks to the smooth-shifting 9-speed automatic transmission. This gearbox keeps the engine in its sweet spot at higher speeds, helping to maximize efficiency during long road trips. Still, this V6 Acadia is not primarily designed for frugal around-town usage.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 GMC Acadia FWD 3.6L 6-cyl is $2,000. This calculation is based on driving 15,000 miles per year, using the national average fuel prices at the time of the EPA’s testing. Keep in mind that these fuel prices fluctuate constantly, so your actual cost could be higher or lower. Remember that driving habits, local traffic conditions, and even tire inflation can influence your real-world fuel expenditure. This figure also assumes you are exclusively using standard unleaded gasoline, as the 3.6L V6 does not require premium fuel.

Real-world expectations

While the EPA’s estimates offer a standardized benchmark, real-world fuel economy often varies. Expect to see figures slightly below the EPA estimates during periods of heavy city driving, especially with frequent short trips that don’t allow the engine to reach optimal operating temperature. Conversely, you might achieve numbers closer to, or even slightly above, the 27 MPG highway rating on long, steady road trips, particularly if you use fuel-efficient driving techniques, such as maintaining a consistent speed and minimizing hard acceleration. Factors like carrying a full load of passengers and cargo, or driving in hilly terrain, will also impact fuel consumption.

How it compares

The Acadia’s fuel economy places it squarely in the middle of its competitive set. The Toyota Highlander V6 FWD, for example, achieves a slightly superior 25 MPG combined. The Honda Pilot, another worthy competitor, lands around the same 22 MPG combined as the Acadia’s front-wheel drive V6 model. These seemingly small MPG differences can add up over the course of a year, potentially saving hundreds of dollars in fuel costs depending on your driving habits. For buyers prioritizing MPG above all else, the Highlander may be the more attractive choice. For others who prefer the Acadia’s styling, interior layout or driving characteristics, the difference may be acceptable. For a broader view, see all Gmc fuel economy data.

Tips to maximize efficiency

Gentle acceleration is key. The Acadia’s 3.6L V6 delivers ample power, but resist the urge to aggressively stomp on the accelerator pedal. Gradual acceleration not only improves fuel economy but also contributes to a smoother and more relaxed driving experience. Avoid flooring the accelerator unless absolutely necessary, as that triggers a substantial increase in fuel consumption.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tires regularly and inflate them to the pressure recommended on the sticker located on the driver’s side doorjamb. This simple step can noticeably improve your fuel economy and extend the life of your tires.

Minimize idling. Idling wastes fuel. If you anticipate stopping for more than a minute or two, turn off the engine. Modern vehicles, including the Acadia, restart quickly and effortlessly, negating any perceived inconvenience. Excessive idling, particularly in stop-and-go traffic, significantly detracts from fuel efficiency.

Plan your routes. Look ahead and anticipate traffic congestion. Choosing routes with fewer stops and starts, and maintaining a consistent speed, can significantly improve fuel economy. Using navigation apps can help you avoid heavily congested areas and find the most efficient routes for your daily commutes.
