EPA Fuel Economy: 31 MPG Combined

The 2025 Ford Fusion SE with the 1.5L EcoBoost 3-cylinder engine delivers an EPA-estimated combined fuel economy rating of 31 miles per gallon, making it an efficient choice for drivers seeking reliable daily transportation without excessive fuel consumption. This mid-size sedan achieves 26 MPG in city driving and 37 MPG on the highway, demonstrating the versatility of Ford’s EcoBoost technology across various driving conditions. The CVT automatic transmission works seamlessly with the turbocharged three-cylinder engine to optimize fuel efficiency while maintaining responsive acceleration when needed.

Ford’s EcoBoost engineering combines direct fuel injection, variable valve timing, and turbocharging to extract maximum efficiency from a smaller displacement engine. The 1.5L EcoBoost powertrain reduces fuel consumption compared to larger naturally aspirated engines while still delivering adequate power for everyday driving. The CVT transmission continuously adjusts gear ratios to keep the engine operating in its most efficient range, contributing to the strong 31 MPG combined rating. For sedan shoppers prioritizing fuel economy without sacrificing practicality, the 2025 Fusion SE represents a balanced approach to efficiency and performance.

City vs Highway Performance

The 2025 Ford Fusion SE shows distinct fuel economy differences between city and highway driving patterns. In city driving, the sedan achieves 26 MPG, which reflects the challenges of frequent acceleration, idling, and lower-speed operation typical of urban environments. Highway driving demonstrates the efficiency advantages of sustained cruising speeds, with the EPA rating of 37 MPG showcasing how the EcoBoost engine performs optimally on open roads. The 11 MPG difference between city and highway ratings is typical for compact sedans and reflects real-world driving physics—highway driving at consistent speeds allows the engine to operate at peak efficiency with minimal acceleration.

The CVT transmission plays a crucial role in both driving scenarios. During city driving, it helps manage the frequent gear adjustments needed for variable speeds. On the highway, the transmission maintains optimal engine RPMs for fuel-efficient cruising. Drivers who spend more time on highways can expect to see fuel economy numbers closer to the 37 MPG rating, while those primarily navigating city streets will experience consumption closer to 26 MPG. Most drivers will find their real-world results falling near the 31 MPG combined estimate, depending on individual driving habits and conditions.

Annual Fuel Cost

Understanding the annual fuel cost of the 2025 Ford Fusion SE helps budget-conscious buyers evaluate the true cost of ownership. Using the EPA combined rating of 31 MPG with standard assumptions of 15,000 miles driven annually and a fuel price of $3.50 per gallon, we can calculate estimated annual fuel expenses.

Fuel Cost Calculation: 15,000 miles ÷ 31 MPG = 483.87 gallons annually. 483.87 gallons × $3.50 per gallon = $1,693.55 annual fuel cost. This calculation provides a baseline estimate for budgeting fuel expenses. Actual costs will vary based on real-world driving patterns, local fuel prices, and individual driving habits. Drivers who primarily navigate highways may see lower annual fuel costs due to the superior 37 MPG highway rating, potentially reducing consumption to approximately $1,453 annually for the same mileage. Conversely, those with primarily city driving may see costs approaching $1,923 annually based on the 26 MPG city rating.

Real-World MPG Expectations

While EPA ratings provide standardized measurements, real-world fuel economy for the 2025 Ford Fusion SE typically ranges between 28 to 33 MPG combined under normal driving conditions. Several factors influence actual efficiency, including driving style, vehicle maintenance, road conditions, and weather. Aggressive acceleration and frequent braking reduce efficiency, while smooth, gradual acceleration preserves fuel economy. Regular maintenance—including proper tire inflation, air filter replacement, and engine tune-ups—ensures the EcoBoost engine operates at peak efficiency.

Weather and seasonal changes affect fuel consumption, with colder temperatures slightly reducing efficiency due to increased engine friction and fuel mixture adjustments. Highway driving at moderate speeds (55-65 MPH) yields the best real-world fuel economy, while excessive idling and short trips with frequent cold starts consume disproportionate fuel. Many owners report achieving the EPA-estimated figures or very close to them when maintaining steady driving patterns and proper vehicle upkeep.

How It Compares

Comparing the 2025 Ford Fusion SE to competing mid-size sedans provides helpful context for fuel economy shoppers. The Honda Accord with a 1.5L turbocharged engine achieves approximately 30 MPG combined, placing it slightly below the Fusion’s 31 MPG combined rating. The Toyota Camry with its standard 2.5L naturally aspirated engine delivers approximately 28 MPG combined, showing the efficiency advantage of EcoBoost’s turbocharged approach. The Hyundai Sonata with a 2.5L engine achieves around 29 MPG combined. The 2025 Fusion SE’s 31 MPG combined rating positions it competitively within the mid-size sedan segment, particularly considering its responsive turbocharged performance.

Tips to Maximize Efficiency

• Maintain proper tire pressure: Check tire pressure monthly, as underinflated tires increase rolling resistance and reduce fuel economy by up to 3 percent.
• Drive smoothly and anticipate traffic: Avoid aggressive acceleration and hard braking. Smooth, gradual acceleration keeps the EcoBoost engine operating efficiently.
• Remove excess weight: Clear unnecessary items from the trunk, as extra weight reduces efficiency, particularly in city driving.
• Use cruise control on highways: Maintaining consistent speeds on open roads helps the CVT transmission operate in its most efficient range.
• Keep up with scheduled maintenance: Follow Ford’s maintenance schedule, including oil changes and air filter replacement, to ensure optimal engine performance and fuel economy.

Frequently Asked Questions
