25 MPG combined isn’t going to win any efficiency awards, but for the 2015 Ford Fusion AWD with the 2.0L EcoBoost engine, it’s an honest and somewhat expected figure. This Fusion isn’t about hypermiling; it’s about providing secure all-weather traction and a reasonable amount of power in a stylish, comfortable package. The typical buyer wants confidence in snow and rain and is willing to trade a few MPG for that peace of mind.

City and highway performance

The EPA estimates for the 2015 Fusion AWD 2.0L break down to 22 MPG in the city and 31 MPG on the highway. The city figure reflects the engine’s need to work harder in stop-and-go traffic. The all-wheel-drive system adds a small amount of rotational mass, and turbocharged engines tend to be less efficient when constantly accelerating. On the open road, however, the Fusion’s well-sorted six-speed automatic transmission and relatively aerodynamic shape allow it to stretch a gallon further. The 31 MPG highway number is achievable, especially on long, flat stretches of highway, but pushing the engine hard for passing or dealing with hilly terrain will quickly bring that number down. It’s a realistic figure, but one that demands a conscious effort to maintain.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Ford Fusion AWD 2.0L at $1,750. This is based on driving 15,000 miles per year and using national average fuel prices. Individual driving habits and varying fuel costs can significantly impact this number. Someone who drives primarily in the city or has a heavy foot will likely spend more, while someone who primarily drives on the highway and is conscientious about fuel efficiency may spend less. The $1,750 figure provides a standardized benchmark for comparing fuel costs across different vehicles, but it should be viewed as an estimate, not a guarantee. Even a slight difference in fuel prices from the national average can quickly impact this value, and is worth researching, even looking at all Ford fuel economy data.

Real-world expectations

While the EPA provides a standardized testing procedure, real-world fuel economy often varies. Fusion AWD 2.0L owners report figures that range from the low 20s to the mid-30s, depending on driving style, terrain, and weather conditions. Expect the lowest numbers in winter, when cold temperatures and the increased rolling resistance of winter tires can significantly reduce fuel efficiency. Aggressive acceleration and frequent hard braking will also take a toll. Conversely, consistently smooth driving on flat terrain in moderate weather can yield results closer to the EPA’s highway estimate, or even slightly better. A consistent 24-27 MPG combined is a reasonable expectation for most drivers who use their Fusion AWD as intended. Check FUSION MPG across all years.

How it compares

The 2015 Ford Fusion AWD 2.0L is in a competitive segment. The Subaru Legacy 2.5i, another popular AWD sedan from the same year, boasts a slightly better 29 MPG combined. However, the Legacy’s 2.5L naturally aspirated engine delivers less power and a less engaging driving experience. The Mazda6, typically praised for its sporty handling and efficient engine, achieves an impressive 29 MPG combined but lacks an AWD option. The Toyota Camry, a perennial favorite for its reliability, offers a combined MPG of 28 in FWD configuration, but no AWD variant. The Honda Accord, an agile and spacious vehicle, gets 30 MPG combined. The buyer choosing the Fusion AWD prioritizes all-weather capability and a more powerful engine over absolute fuel efficiency, accepting the MPG trade-off in exchange for those features. For that person, these other options aren’t viable.

Tips to maximize efficiency

Avoid aggressive acceleration. The 2.0L EcoBoost engine delivers ample power, making it tempting to use it frequently. However, each hard acceleration cycle burns significantly more fuel. Accelerate smoothly and gradually to minimize fuel consumption, especially since the turbocharger needs fuel to create boost.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the driver’s side door jamb. Since this Fusion often tackles winter weather, remember that tire pressure decreases as the temperature drops.

Minimize idling. Idling the engine wastes fuel and contributes to unnecessary emissions. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to be restarted frequently without causing excessive wear and tear. This is especially important in colder climates where lengthy warm-ups can drain fuel rapidly.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel efficiency. Avoid excessive speed changes when using cruise control. Anticipate changes in terrain and adjust your speed gradually, rather than relying on the cruise control to constantly accelerate and decelerate.

Reduce excess weight. Carrying unnecessary weight in your vehicle reduces fuel economy. Remove any unnecessary items from the trunk and passenger compartment. Every extra pound puts additional strain on the engine, regardless of whether it’s a bag of golf clubs or a box of old books.
