The 2016 GMC Acadia AWD 3.6L gets 17 MPG combined, which is not particularly fuel efficient, nor is it expected to be. This is a large, comfortably appointed SUV designed primarily for family use, and efficiency is secondary to space, capability, and a smooth ride. Buyers aren’t necessarily prioritizing Prius-like economy when shopping for this Acadia; they’re looking at the whole package and making calculated trade-offs.

City and highway performance

The EPA estimates for the 2016 GMC Acadia AWD with the 3.6L V6 are 15 MPG in the city and 22 MPG on the highway. The city figure reflects the Acadia’s weight and the demands of stop-and-go traffic. The highway number, while seemingly more respectable, still lags behind newer models in the segment. Factors impacting these figures include the six-speed automatic transmission (newer competitors feature more gears for improved efficiency) and the inherent drag of the Acadia’s full-size SUV shape, increased in this model by the added weight and friction of standard all-wheel drive. This vehicle is engineered for confident traction in all conditions, not for squeezing every last mile from a gallon of fuel.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2016 GMC Acadia AWD 3.6L is estimated at $2,600. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Individual driving habits and local fuel costs will certainly affect this number, but it provides a standardized benchmark for comparing the Acadia’s fuel costs against other vehicles in its class and can be viewed with ACADIA MPG across all years.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the 2016 GMC Acadia AWD often varies. Drivers who frequently engage the all-wheel-drive system, tow trailers, or drive aggressively can expect to see figures closer to the city estimate, or even lower. Those who primarily drive on the highway at steady speeds may achieve slightly better than the EPA’s 22 MPG. Overall, achieving the combined 17 MPG consistently requires careful driving and a moderate mix of city and highway conditions.

How it compares

The 2016 GMC Acadia’s fuel economy is generally similar to its direct competitors from that model year. For example, the 2016 Honda Pilot AWD offers an EPA-estimated 19 MPG combined, with 18 MPG city and 26 MPG highway, a noticeable advantage, but achievable only in the top-spec Touring trim when equipped with the 9-speed automatic. Opting for the standard 6-speed transmission brings the Pilot down to a more comparable 18 MPG combined. The 2016 Toyota Highlander AWD nets around 20 MPG combined. The slight edge of the Toyota and Honda matters to buyers cross-shopping for a practical and reliable family hauler, and who aren’t necessarily enticed by the Acadia’s particular blend of traditional SUV styling and greater towing capacity. Owners looking for all Gmc fuel economy data may want to cross-shop other models in the brand’s lineup.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The 3.6L V6 responds well to a light foot; accelerating gently and anticipating traffic flow will significantly reduce fuel consumption. The Acadia’s weight requires extra energy to get moving and to stop, so smooth, gradual inputs are key.

Maintain proper tire inflation. Under-inflated tires increase rolling resistance, forcing the engine to work harder and burning more fuel. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure and check them regularly, especially during seasonal temperature changes.

Reduce unnecessary weight. Carrying excessive cargo in the Acadia adds extra weight, decreasing fuel economy. Remove any items you don’t need on a regular basis, such as sporting equipment or tools. A lighter vehicle is inherently more efficient.

Minimize idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you’re going to be stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, so you won’t cause undue wear and tear.

Plan your trips strategically. Combining errands into a single trip and avoiding peak traffic times can help improve fuel economy. Short trips with cold starts are particularly inefficient, as the engine takes time to reach its optimal operating temperature. Smart planning can significantly reduce overall fuel consumption.
