25 MPG combined is adequate for the 2023 GMC Acadia FWD 2.0L 4-cyl, a mid-size SUV designed for suburban families who need a practical, comfortable, and reasonably efficient vehicle. It’s not going to win any hypermiling competitions, but it’s a reasonable trade-off for the space and versatility it offers. This configuration is for those who prioritize fuel efficiency over all-wheel drive capability, accepting front-wheel drive for the benefits at the pump.

City and highway performance

The EPA estimates the Acadia FWD with the 2.0L turbo achieves 22 MPG in the city and 29 MPG on the highway. The city figure is decent for stop-and-go traffic, where the engine’s stop/start system (which can be disabled) can help save fuel. The 29 MPG highway rating reflects the Acadia’s aerodynamic profile and the 9-speed automatic transmission, which allows the engine to run at lower RPMs at cruising speeds, improving fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 GMC Acadia FWD 2.0L at $1,750. This estimate is based on driving 15,000 miles per year and assuming current national average fuel prices. This figure provides a benchmark for prospective buyers who are budgeting for vehicle ownership costs. Actual fuel costs can vary based on individual driving habits, local fuel costs, and the percentage of city versus highway driving.

Real-world expectations

While the EPA numbers provide a standardized metric, real-world fuel economy depends on driving style and conditions. Aggressive acceleration, frequent hard braking, and carrying heavy loads will lower fuel economy. Smooth acceleration, maintaining a consistent speed, and optimizing tire pressure can help drivers approach or even exceed the EPA estimates. The relatively small displacement 2.0L turbocharged engine in the Acadia can be susceptible to greater swings in MPG based on driving style, especially when compared to larger displacement engines that do not need to work as hard.

How it compares

Compared to other mid-size SUVs in its class, the 2023 GMC Acadia FWD 2.0L’s fuel economy is competitive, but not class-leading. For example, the Toyota Highlander FWD with its 2.4L turbocharged engine achieves an EPA-estimated 25 MPG combined, mirroring the Acadia. The Honda Pilot, with its larger 3.5L V6, lands around 22 MPG combined in its FWD configuration. The Nissan Pathfinder FWD, also equipped with a V6, gets comparable numbers to the Pilot, around 21-22 MPG combined. All Gmc fuel economy data shows that moving to the Acadia AWD usually drops the combined MPG a few points. For buyers prioritizing a balance of fuel efficiency and cargo space, the Acadia, Highlander and similar models are appealing choices. Those more concerned with performance or towing capability might accept the lower fuel economy of V6-powered alternatives.

Tips to maximize efficiency

Use the Acadia’s cruise control system on highway drives to maintain a constant speed and minimize unnecessary acceleration and braking. Consistent speed is key to fuel efficiency, and cruise control helps achieve this, especially on long trips. Avoid abrupt lane changes or speed fluctuations to further optimize your MPG on the highway.

Ensure that your tires are properly inflated to the recommended pressure, which can be found on the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, negatively impacting fuel economy. Check your tire pressure regularly, especially during seasonal temperature changes, as pressure can fluctuate.

Reduce unnecessary weight in the vehicle. Carrying excess cargo adds to the vehicle’s overall weight, requiring the engine to work harder and consume more fuel. Remove any items you don’t need, such as sporting equipment or tools, to improve fuel efficiency. This can have a surprisingly significant impact, especially on a smaller displacement engine like the 2.0L turbo.

Minimize idling time. If you anticipate waiting for more than a minute, turn off the engine. Excessive idling consumes fuel without moving the vehicle. Many modern vehicles, including the Acadia, have an automatic start/stop feature that shuts off the engine at stoplights, reducing fuel consumption, though drivers can manually disable this feature if preferred.

Consider using a fuel additive designed to clean fuel injectors. Over time, deposits can build up in the injectors, hindering their ability to spray fuel efficiently. A fuel injector cleaner can help remove these deposits, restoring optimal fuel delivery and improving fuel economy. Using the manufacturer’s recommended oil type and following the recommended maintenance schedule for the engine can also help sustain optimal performance and efficiency. Owners can also examine ACADIA MPG across all years to look for historical trends in MPG data.
