Owners of the 2016 GMC Acadia FWD with the 3.6L V6 experience 18 MPG combined. It’s an acceptable but unremarkable figure, a compromise most Acadia buyers are fully aware of and willing to make given what the vehicle offers: space, seating for up to eight, and a comfortable, if not particularly exciting, driving experience. Few people are cross-shopping an Acadia against a Prius; they need the utility and have reconciled with the fuel consumption.

City and highway performance

The difference between city and highway MPG reveals more about the Acadia’s fuel usage. The EPA estimates 15 MPG in the city, a number that can feel even lower when you’re constantly accelerating from stoplights with a full load of passengers. The 3.6L V6 needs to work hard to get the Acadia moving, especially when loaded with kids, cargo, or both. Out on the open road, things improve, but the 22 MPG highway rating isn’t particularly impressive. Long road trips will highlight the contrast between the Acadia’s comfortable cruising ability and its relatively frequent stops for fuel. The aging six-speed automatic transmission, while smooth enough, does little to help efficiency; a more modern eight- or nine-speed unit would undoubtedly improve the numbers.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,450 for the 2016 GMC Acadia FWD. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also assumes national average fuel prices remain consistent throughout the year. Of course, individual driving habits and variations in local fuel costs can significantly impact the actual amount you’ll spend at the pump. Aggressive driving, frequent short trips, and consistently higher fuel prices will all push that $2,450 figure upwards, while a more careful driver living in an area with lower gas prices could potentially save some money.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world MPG often differs. Many Acadia owners report numbers that hover right around the EPA estimates, while some claim slightly better highway mileage if they are careful about fuel-efficient driving. Cold weather, which is known to reduce fuel economy, can also drop mileage on the Acadia. Driving style is a major factor. Drive it like a truck, and gas mileage will suffer. Drive it with a gentle foot, and fuel economy will improve. Given the Acadia’s mission as family transportation, the odds are high that at least some passengers are actively working against gentle driving.

How it compares

The 2016 Acadia existed in a crowded segment with several competitors. The Toyota Highlander, a perennial favorite, consistently achieves slightly better MPG. The Highlander’s V6 engine offers close to 20 MPG combined, a tangible advantage. The Honda Pilot, known for its efficient packaging, also beats the Acadia, getting close to 21 MPG combined. Even within the GM family, the Buick Enclave, mechanically similar to the Acadia, manages to eke out slightly better fuel economy numbers largely due to minor differences in tuning and features. These small gains can add up over the years. All Gmc fuel economy data shows where the Acadia sits within the broader brand lineup, which includes more economical options.

Tips to maximize efficiency

Avoid aggressive acceleration. The 3.6L V6 is responsive, but every quick press of the throttle uses more fuel. Ease into the accelerator pedal, especially from a standstill, and let the engine build speed gradually.

Maintain proper tire inflation. Underinflated tires increase rolling resistance and reduce fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker.

Reduce unnecessary weight. The Acadia is already a heavy vehicle, so remove any excess cargo from the trunk or cargo area. Extra weight adds to the engine’s workload.

Use cruise control on the highway. Maintaining a consistent speed helps to optimize fuel efficiency. Cruise control prevents speed fluctuations and helps minimize unnecessary throttle adjustments.

Consider routes that minimize stop-and-go traffic. Idling consumes fuel without covering any distance. Planning your routes to avoid congested areas can make a difference, especially in the city.

ACADIA MPG across all years makes it clear that fuel economy has never been a primary selling point.
