25 MPG combined is a respectable showing for the 2018 Ford Fusion FWD 2.5L 4-cyl, putting it squarely in the ballpark for midsize sedans of its era. This isn’t a hybrid or a performance model straining for efficiency; it’s the base engine in a car prized for its comfortable ride, spacious interior, and attractive price point. This Fusion appeals to budget-conscious buyers who need a reliable daily driver, and for these drivers, 25 MPG is an acceptable, if not exceptional, trade-off for the car’s other virtues.

City and highway performance

The EPA estimates 21 MPG in the city and 32 MPG on the highway for this Fusion. The city figure reflects the engine’s tendency to work harder in stop-and-go traffic, where the six-speed automatic transmission cycles frequently. The highway number demonstrates the engine’s efficiency when cruising at a steady speed, especially with the transmission locked in its highest gear. These numbers highlight the Fusion’s suitability for drivers who do a mix of commuting or prioritize long-distance travel.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,750 for the 2018 Ford Fusion FWD 2.5L 4-cyl. This figure is based on driving 15,000 miles per year and using national average fuel prices. Of course, your individual fuel costs may vary depending on your driving habits, the type of roads you typically drive, and changes in fuel prices. This $1,750 provides a useful benchmark for comparing the Fusion’s fuel expenses to those of other vehicles. Remember to compare this to all Ford fuel economy data to put this number in perspective.

Real-world expectations

While the EPA figures provide a standardized measurement, real-world fuel economy always varies. Many drivers match or slightly exceed the EPA’s highway rating, especially on long road trips. Aggressive driving, heavy traffic, and frequent cold starts can lower the city MPG figure. Drivers who live in hilly areas may see a further reduction in fuel economy. Keep a log of your fuel consumption for a few months after purchasing a used 2018 Fusion to get an accurate picture of what you can expect.

How it compares

In the midsize sedan segment, the 2018 Fusion’s fuel economy is competitive but not class-leading. For example, the Toyota Camry LE with its 2.5L engine achieves an EPA-estimated 28 MPG combined, while the Honda Accord LX, with its 1.5L turbocharged engine, is rated at 33 MPG combined. The Chevrolet Malibu with its base 1.5L turbo manages 30 MPG combined. These differences are significant enough for economy-minded shoppers to take note, yet the Fusion provides a more pleasant interior experience. It is important for buyers to decide what they value most. You can also compare the FUSION MPG across all years to see how this economy compares to other years of the Fusion generation.

Tips to maximize efficiency

Maintaining proper tire inflation is critical for maximizing fuel economy in any vehicle, and the 2018 Fusion is no exception. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel.

Avoid aggressive acceleration and braking. The 2.5L engine in the Fusion is responsive enough to provide adequate power without needing to be pushed hard. Gentle acceleration and smooth braking will save fuel and reduce wear and tear on your vehicle.

Reduce unnecessary weight in the vehicle. Carrying extra cargo in the trunk or backseat adds weight, which reduces fuel economy. Remove any items that you don’t need on a regular basis, such as sports equipment or tools. Also, avoid using a roof rack unless you absolutely need it, as it increases aerodynamic drag.

Use cruise control on the highway whenever possible. Cruise control helps maintain a consistent speed, which reduces fuel consumption. Just remember to disable cruise control in wet conditions, and be aware of how your car handles in different conditions.
