The process involves several key changes to ensure the vehicle can handle the higher ethanol content in E85. Below are the required modifications for flex fuel use in an ’07 Fusion.
Engine and Fuel System Upgrades
The first and most critical modification is upgrading the fuel system to handle E85. Ethanol is more corrosive than gasoline and can degrade rubber components over time. Therefore, all fuel lines, hoses, seals, and gaskets must be replaced with ethanol-compatible materials, typically made from materials like Viton or Teflon. Additionally, the fuel injectors may need to be upgraded to handle the increased fuel flow required by E85, as it has a lower energy density than gasoline. A higher-capacity fuel pump is also recommended to ensure adequate fuel delivery under all driving conditions.
ECU Tuning and Flex Fuel Sensor
The engine control unit (ECU) must be reprogrammed to recognize and adjust for the use of E85. This involves installing a flex fuel sensor, which detects the ethanol content in the fuel and sends this information to the ECU. The ECU then adjusts the fuel injection timing and air-fuel mixture to optimize performance and prevent engine damage. Without proper tuning, the engine may run lean, leading to overheating and potential damage. Professional tuning is highly recommended to ensure the ECU is calibrated correctly for both gasoline and E85.
Exhaust System and Oxygen Sensors
E85 combustion produces different byproducts compared to gasoline, which can affect the exhaust system. Upgrading to stainless steel or coated exhaust components is advisable to prevent corrosion. Additionally, the oxygen sensors should be replaced with wideband sensors capable of accurately reading the richer fuel mixture of E85. This ensures the ECU receives precise data to maintain optimal engine performance and emissions compliance.
Cold Start and Vapor Management
E85 has a higher evaporation temperature than gasoline, which can make cold starts more challenging. Installing a flex fuel-compatible cold start system or adding a fuel heater can mitigate this issue. Furthermore, the vehicle’s evaporative emissions system (EVAP) may require modifications to handle the increased vapor pressure of E85. This includes upgrading the charcoal canister and ensuring all EVAP components are ethanol-resistant.

Performance Impact of E85 on 07 Fusion
The 2007 Ford Fusion is not factory-equipped to run on E85 flex fuel without modifications. E85, a blend of 85% ethanol and 15% gasoline, has different combustion properties compared to regular gasoline, which can significantly impact the performance of a vehicle not designed for it. If an 07 Fusion were to use E85 without proper adjustments, it could experience issues such as reduced fuel efficiency, engine knocking, and potential long-term damage due to the higher corrosiveness of ethanol. However, with appropriate modifications, such as upgrading the fuel system and tuning the engine management system, the Fusion could potentially utilize E85, albeit with altered performance characteristics.
One of the most noticeable performance impacts of E85 on an 07 Fusion would be the change in power output. Ethanol has a higher octane rating than gasoline, which can allow for more aggressive ignition timing and potentially increase horsepower. However, ethanol also has a lower energy density, meaning the engine would require more fuel to produce the same amount of power. This could result in a slight decrease in overall performance unless the engine is specifically tuned to take advantage of E85's properties. Additionally, the cooling effect of ethanol during combustion might help reduce engine temperatures, which could be beneficial under high-load conditions.
Fuel efficiency is another critical area affected by E85. Due to its lower energy content, E85 typically results in a 15-25% reduction in miles per gallon compared to gasoline. For an 07 Fusion, this means more frequent refueling and higher fuel costs, even though E85 is often cheaper per gallon. Owners considering E85 should weigh the cost savings against the reduced efficiency and ensure their driving habits align with the fuel's characteristics. It's also important to note that consistent use of E85 without proper modifications could lead to premature wear on fuel system components, further impacting long-term performance.
The impact of E85 on emissions and drivability is another factor to consider. Ethanol burns cleaner than gasoline, potentially reducing certain emissions like carbon monoxide and hydrocarbons. However, it can increase others, such as acetaldehyde. In terms of drivability, E85's higher octane rating might provide a smoother idle and reduced engine knock, but the lower energy density could make the vehicle feel less responsive, especially during acceleration. For an 07 Fusion, achieving optimal performance with E85 would require careful calibration of the engine control unit (ECU) to balance these factors.
Lastly, the long-term reliability of an 07 Fusion running on E85 depends heavily on the extent of modifications made. Without upgrades to the fuel injectors, fuel lines, and seals, the corrosive nature of ethanol could accelerate wear and lead to leaks or failures. Additionally, the engine's compression ratio and ignition timing must be optimized for E85 to avoid detonation and maximize efficiency. While E85 can offer certain performance benefits, it requires a significant investment in modifications and maintenance to ensure the Fusion operates reliably and efficiently. For most 07 Fusion owners, sticking to gasoline is the safer and more practical choice unless they are willing to undertake these modifications.
