The 2017 GMC Acadia AWD 3.6L gets 20 MPG combined. While not the most efficient, it’s a practical choice for those needing passenger and cargo space with all-wheel drive in a mid-size SUV. This Acadia generation suits families and group transportation needs, where functionality often outweighs the desire for extremely low fuel consumption.

City and highway performance

The EPA estimates 18 MPG in the city and 25 MPG on the highway, showing the Acadia’s fuel economy strengths and weaknesses. City driving with frequent stops will likely result in fuel economy closer to 18 MPG. The Acadia’s weight, along with constant acceleration, contributes to this. However, on the highway at a steady speed, the 3.6L V6 can get closer to 25 MPG. This highway number is good for a vehicle of this size and all-wheel-drive capability, suggesting that long road trips won’t be as expensive as daily commutes.

Annual fuel cost

The EPA projects an annual fuel cost of $2,200 for the 2017 GMC Acadia AWD 3.6L. This is based on driving 15,000 miles annually and using the national average fuel price. It’s a benchmark for comparing vehicle running costs, but your actual expenses will change based on your driving, local fuel prices, and driving conditions. Aggressive driving, short trips, and idling will increase fuel consumption and could raise your annual fuel bill above the EPA estimate.

Real-world expectations

The EPA provides standardized testing for vehicle comparisons; however, real-world fuel economy for the 2017 GMC Acadia AWD 3.6L is affected by driving style, load, and terrain. Owners regularly driving with many passengers and cargo, especially in hilly areas, should expect MPGs near the lower end of the EPA’s range. Those using the Acadia for solo commutes or occasional family trips, and who drive more carefully, might achieve slightly better results. Reading reviews from other owners of the same model can give you a good idea of average real-world MPG in various conditions.

How it compares

The 2017 Acadia’s fuel economy is average among mid-size, three-row SUVs with all-wheel drive. For instance, the Toyota Highlander AWD with its 3.5L V6 engine gets an EPA-estimated 20 MPG combined, similar to the Acadia. The Honda Pilot AWD, another popular option, also has a 20 MPG combined EPA rating with its 3.5L V6. A slightly smaller and often more fuel efficient choice is the Nissan Pathfinder, which, with AWD, can reach up to 22 MPG combined with its 3.5L V6.

Tips to maximize efficiency

Limit idling time. The 3.6L V6 uses fuel even when stopped, so avoid idling, particularly in cold weather when the engine works harder. Turn off the engine if you’ll be stopped for more than a minute or two.

Keep tires properly inflated. Underinflated tires increase rolling resistance and reduce fuel efficiency, also affecting handling and tire wear. Regularly check your tire pressure and inflate them to the recommended level in the owner’s manual or on the driver’s side doorjamb.

Use cruise control wisely. On flat highways, cruise control can maintain a consistent speed and optimize fuel economy. Don’t use it in hilly areas, where the transmission might downshift often, negating fuel savings. Pay attention to the road and gradually adjust your speed based on the terrain.

Reduce weight in the vehicle. Extra cargo increases the vehicle’s weight, requiring more energy to accelerate and maintain speed. Remove items you don’t regularly need.

Be aware of AC usage. The air conditioning puts a load on the engine, especially at lower speeds. Use it sparingly, and consider opening windows or using the ventilation system instead, especially in mild weather. You can also research ACADIA MPG across all years.

While the 2017 GMC Acadia AWD 3.6L isn’t a hybrid, it offers a good mix of space, capability, and fuel economy for its target market. For those wanting fuel efficiency across the GMC lineup, check all Gmc fuel economy data.
