The 2015 Ford Fusion FWD with the 2.0L EcoBoost engine achieves 26 MPG combined, which is a reasonable balance. This Fusion appealed to buyers seeking a stylish, well-equipped car that wouldn’t completely drain their bank accounts at the pump. It prioritized a nicer interior and a more powerful engine over ultimate fuel efficiency.

City and highway performance

The EPA estimates are 22 MPG in the city and 33 MPG on the highway. The city figure is unremarkable. Stop-and-go traffic and the engine’s 240 horsepower will likely mean you get closer to the lower end of that estimate. However, on the open road, the Fusion rewards sensible driving. The automatic transmission shifts smoothly and efficiently, allowing the engine to cruise. Achieving or even slightly exceeding that 33 MPG highway rating is possible with a light foot and consistent speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Ford Fusion FWD 2.0L is $1,700. This is based on driving 15,000 miles per year and using national average fuel prices. This number is just an estimate, your actual fuel costs will vary depending on your driving habits, the type of driving you do (more city vs. highway), and fluctuations in fuel prices. Aggressive accelerations and frequent hard braking will quickly inflate that $1,700 figure, while a more conservative approach to driving will help keep it in check. The estimate also presumes the use of regular unleaded gasoline, which the 2.0L EcoBoost engine is designed to burn.

Real-world expectations

The EPA estimates provide a useful baseline. 2015 Fusion 2.0L owners report combined fuel economy figures that hover around the EPA’s 26 MPG estimate, but variations are common. Drivers who frequently drive through congested urban environments may see averages closer to 20-23 MPG, while those who primarily drive highway miles can realistically achieve 30 MPG or higher. Driving style is important: lead-footed drivers will pay more at the pump, while those who prioritize smooth acceleration and consistent speeds will save gas. Factors like tire pressure, vehicle maintenance, and even the use of accessories like air conditioning can subtly impact fuel consumption.

How it compares

In the 2015 mid-size sedan segment, the Fusion’s 26 MPG combined wasn’t class-leading, but it wasn’t last either. A comparable 2015 Toyota Camry with its 2.5L four-cylinder engine delivered a similar 28 MPG combined. The Honda Accord, another popular choice, often exceeded the Fusion’s figures slightly near 27 MPG combined. The Mazda6, known for its engaging driving dynamics, offered around 29 MPG combined. The Fusion offered a stylish design and interior, while the Camry prioritized reliability and resale value. For buyers who wanted the best fuel efficiency, the hybrid versions of the Fusion, Camry, and Accord were the way to go. Review FUSION MPG across all years here.

Tips to maximize efficiency

Consistent maintenance is important. Ensure that your tires are properly inflated, as underinflated tires increase rolling resistance and reduce fuel economy. Regularly check and replace the air filter to ensure optimal engine performance. Adhere to the manufacturer’s recommended oil change intervals using the correct type of oil, old or incorrect oil can negatively impact engine efficiency.

Anticipate traffic flow to minimize unnecessary braking and acceleration. Maintaining a steady speed is more fuel-efficient than constantly speeding up and slowing down. If possible, use cruise control on the highway to maintain a consistent speed and optimize fuel consumption. Avoid aggressive driving habits such as rapid acceleration and hard braking, as these actions significantly reduce fuel economy.

Reduce unnecessary weight. Carrying excess cargo in your trunk or back seat puts additional strain on the engine, leading to increased fuel consumption. Remove any items you don’t need, such as sports equipment or tools, to lighten the load. Also, consider removing roof racks or cargo carriers when not in use, as they create aerodynamic drag and reduce fuel efficiency.

Consider using “Eco” mode when appropriate. The Fusion’s Eco mode, if equipped, adjusts throttle response and transmission shift points to prioritize fuel efficiency over performance. While it may make the car feel slightly less responsive, it can yield improvements in fuel economy, especially in city driving. Use Eco mode when maximum performance is not required.

Plan your trips strategically. Combine multiple errands into a single trip to minimize cold starts, which are less fuel-efficient. Identify the least congested routes to avoid stop-and-go traffic and reduce idling time. Consider using a navigation app to find the most efficient route based on real-time traffic conditions.
