17 MPG combined defines the 2017 GMC Acadia Limited AWD 3.6L. It’s not a great figure in a world of efficient crossovers. But to understand this Acadia, consider its purpose. It’s a family vehicle designed to haul people and cargo comfortably and reliably, even when the pavement ends or the weather turns foul, not to win any fuel economy contests. Its buyers prioritize space, capability, and GMC’s strong image far above ultimate efficiency. They understand the tradeoff in a larger, all-wheel-drive SUV and accept the fuel costs of owning a vehicle that meets their specific needs. They’re likely not cross-shopping hybrids; instead, they’re comparing it to other traditional SUVs where compromises are common.

City and highway performance

The EPA estimates the 2017 Acadia Limited AWD at 15 MPG in the city and 22 MPG on the highway. 15 MPG in the city is unremarkable, but the 22 MPG highway rating is respectable for a vehicle of this size and weight. This suggests the engine and transmission are reasonably efficient at maintaining cruising speeds on level ground. Stop-and-go city driving is where this Acadia’s fuel consumption suffers. This is typical of larger, naturally aspirated engines in heavier vehicles, particularly when paired with an older six-speed automatic transmission. The AWD system provides added traction and security, and it also contributes to the lower city MPG figure due to the added weight and mechanical losses.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 GMC Acadia Limited AWD at $2,600. This calculation is based on driving 15,000 miles per year, with a mix of city and highway driving, using the national average fuel price. This is simply an estimate. Those who drive primarily in the city, have heavier feet, or live in areas with higher fuel prices will likely find their actual fuel costs exceeding this figure. Drivers who primarily rack up highway miles and practice fuel-efficient driving techniques might see a somewhat lower annual cost.

Real-world expectations

The EPA provides a standardized benchmark, but real-world fuel economy will vary based on individual driving habits, traffic conditions, and terrain. Expect to see numbers generally in line with the EPA estimates, but recognize that aggressive driving, frequent short trips, and towing will significantly decrease fuel economy. Owners who frequently engage the all-wheel-drive system in challenging conditions should also anticipate lower MPG figures. Regularly maintaining the vehicle, including proper tire inflation and timely servicing, can help to ensure that fuel economy remains as close as possible to the EPA estimates. For a broader view, consider checking out ACADIA MPG across all years.

How it compares

The 2017 GMC Acadia Limited AWD 3.6L wasn’t a fuel economy leader in the midsize SUV category. Consider its competition. The 2017 Toyota Highlander AWD with its 3.5L V6, for example, was rated at 20 MPG combined. Even the larger, more powerful 2017 Ford Explorer with its 3.5L V6 and AWD managed around 19 MPG combined in some trims. The Jeep Grand Cherokee with its 3.6L V6 and 4×4 system could be expected to deliver similar fuel mileage to the Acadia. These slightly better figures are meaningful to buyers who want the capabilities of a larger vehicle but are still concerned about fuel costs. Buyers likely aren’t comparing this to smaller crossovers with turbo-four engines, or to highly efficient hybrids, they’re comparing it to other vehicles that offer the space and towing capacity they need.

Tips to maximize efficiency

Minimize idling. The Acadia’s 3.6L V6 consumes a noticeable amount of fuel while idling. Avoid unnecessary idling, especially in stop-and-go traffic or waiting situations. Turning off the engine during prolonged stops, where safe to do so, can help conserve fuel.

Maintain optimal tire pressure. Properly inflated tires reduce rolling resistance, which directly impacts fuel economy. Check your tire pressure regularly (at least once a month) and inflate tires to the recommended pressure found on the driver’s side doorjamb sticker. Even a few PSI below the recommended pressure can negatively affect fuel consumption.

Drive smoothly and avoid aggressive acceleration. The Acadia’s six-speed automatic transmission is programmed for both performance and efficiency. Smooth, gradual acceleration allows the transmission to shift efficiently and keeps the engine operating in its most efficient range. Avoid abrupt starts and stops, which waste fuel and increase wear and tear on your vehicle.

Lighten the load. Carrying unnecessary weight in your Acadia puts extra strain on the engine and reduces fuel economy. Remove any items from your vehicle that you don’t need on a regular basis, such as sports equipment, tools, or other heavy objects. The less weight the engine needs to move down the road, the less fuel it will consume.

Consider using cruise control on the highway. Engaging cruise control on long highway drives can help maintain a consistent speed and prevent unintentional speeding, both of which improve fuel efficiency. Be mindful of traffic conditions and disengage cruise control when necessary to maintain safe following distances. For those looking for more insight, explore all Gmc fuel economy data.
