What You'll Learn
Fuel tank capacity varies across models
The fuel tank capacity of a car varies depending on the model and its configuration. The Ford Fusion, for example, offers a range of fuel tank capacities across its different models and configurations.
The 2006-2010 Ford Fusion model has a fuel tank capacity of 45 litres or 16.5 gallons. This is supported by a forum user who noted that their 2007 Fusion AWD had a fuel tank capacity of 17.5 gallons, but they had only ever filled it with just over 17 gallons of fuel.
However, another forum user with a 2017 Ford Fusion Sport claimed that their fuel tank capacity was 16.5 gallons, as they had never filled their tank with more than 15.492 gallons of fuel. This discrepancy could be due to the different model years or variations in the sport configuration.
The Ford Fusion with the base-level 2.5L Duratec 4-cylinder engine has a fuel tank capacity of 16.5 gallons. Meanwhile, the AWD configuration of the same model has a larger fuel tank capacity of 18 gallons.
The Ford Fusion with the 2.0L Atkinson-Cycle Hybrid 4-cylinder engine has a smaller fuel tank capacity of 14 gallons, which is likely due to the hybrid engine's increased fuel efficiency.
It's important to note that the fuel tank capacity of a car is not the same as the amount of fuel that can be filled. There needs to be room for fuel expansion, especially during hot weather, and some fuel may remain in the lines even when the tank is empty.

Fuel tank size differs for front-wheel drive and all-wheel drive
The fuel tank size of the Ford Fusion differs depending on the type of drive system the car is equipped with. The front-wheel-drive (FWD) model has a larger fuel tank capacity when compared to its all-wheel-drive (AWD) counterpart.
According to some sources, the Ford Fusion with front-wheel drive has a fuel tank capacity of 17.5 gallons (66.2 litres). This information is supported by the owner's manual for the 2008 Ford Fusion SEL I-4 FWD and V-6 FWD models, which states a fuel tank capacity of 17.5 gallons.
On the other hand, the all-wheel-drive Ford Fusion has a slightly smaller fuel tank. The owner's manual for the 2007 Fusion AWD mentions a fuel tank capacity of 16.5 gallons (62.5 litres). This is a difference of 1 gallon or approximately 3.7 litres when compared to the front-wheel-drive model.
It's worth noting that there may be some variation in fuel tank capacity depending on the specific model year and trim level of the Ford Fusion. For example, one source mentions that the 2020 Ford Fusion FWD has a fuel tank capacity that allows for 90% usage before refuelling, without specifying the exact capacity in gallons or litres. Additionally, another source mentions that the Ford Fusion with a 2.5L Duratec 4-cylinder engine has a 16.5-gallon fuel tank, while the AWD configuration of the same engine has a larger 18-gallon fuel tank.
The Ford Fusion also offers hybrid engine options, such as the 2.0L Atkinson-Cycle Hybrid 4-cylinder engine, which has a smaller 14-gallon fuel tank. This hybrid engine achieves an impressive EPA-estimated fuel economy of 43/41/42 MPG for city, highway, and combined driving, respectively.

Fuel efficiency depends on engine type
The fuel tank capacity of the Ford Fusion is disputed. Some sources state that the tank capacity is 18 gallons, while others claim it to be 16.5 gallons. One owner of a Ford Fusion Sport stated that they had never filled their tank with more than 15.492 gallons of fuel.
Fuel efficiency is dependent on many parameters, including engine type and engine parameters. The engine type and its specifications will determine the fuel efficiency of a vehicle, as each engine has unique thermal efficiency characteristics. For example, a gasoline engine burns a mix of gasoline and air, with a ratio of about 12-18 parts of air to one part of fuel. A mixture with a 14.7:1 air/fuel ratio is stoichiometric, meaning that when burned, 100% of the fuel and oxygen are consumed. However, mixtures with slightly less fuel, called lean burn, are more efficient. Additionally, the efficiency of an engine is defined as the ratio of useful work done to the heat provided, and engine efficiency is highest when the engine is operating at full throttle.
The type of engine will also determine the gross heat of combustion and the net heat of combustion, which affect the theoretical amount of mechanical energy that can be obtained from the reaction. For example, a gasoline engine can achieve a figure of 17.6 MJ/kg, while a diesel engine can achieve 19.1 MJ/kg. The energy efficiency in transport is then calculated as the useful travelled distance divided by the total energy put into transport propulsion.
Other factors that contribute to fuel efficiency include transmission design, tire design, aerodynamic drag, weight, AC usage, fuel, and rolling resistance. Additionally, fuel efficiency can be improved through careful maintenance and driving habits. For instance, hybrid vehicles improve fuel efficiency by recapturing kinetic energy that would otherwise be lost as heat during braking and using it as electrical power.

Fuel tank capacity vs usable capacity
The fuel tank capacity of a Ford Fusion is stated as 18 gallons in the manual. However, one owner of a 2017 Ford Fusion Sport has questioned this, stating that they have never filled their tank with more than 15.492 gallons of fuel, and on one occasion, 16.423 gallons. This discrepancy between the stated fuel tank capacity and the amount of fuel that can be practically added to the tank is a common issue.
Fuel tank capacity and usable capacity are two distinct concepts that are important for understanding how far a vehicle can travel between refuelling stops. The fuel tank capacity is the total internal volume of the tank, indicating its maximum potential for fuel storage. However, the usable capacity is the amount of fuel that can be practically utilised, and it is typically less than the total capacity. This difference arises due to various factors, including regulatory filling limits, physical design considerations, and the need to accommodate fuel expansion.
Regulatory guidelines recommend filling fuel tanks to no more than 95% of their rated capacity, and often suggest a more conservative 90% limit. This is done to allow for fuel expansion, especially in hot weather, and to maintain operational safety. Additionally, the placement of the fuel pump within the tank can further reduce the usable capacity. The pump is usually installed above the bottom of the tank to prevent sediment intake, resulting in a portion of the fuel being inaccessible.
The usable capacity of a fuel tank is calculated as 90% of the tank's internal volume, minus the volume of fuel below the fuel pump. This calculation ensures that the tank is not overfilled, and that there is space for the fuel to expand. In practice, the usable capacity may be further reduced by factors such as the shape and design of the tank, as well as individual driving habits and fuel efficiency.
Understanding the usable capacity of a fuel tank is crucial for efficient trip planning and fuel management. While the fuel tank capacity provides a maximum volume, the usable capacity represents the practical amount of fuel that can be utilised before refuelling becomes necessary. This distinction is important for vehicle owners to avoid running out of fuel and to make informed decisions about their refuelling needs.

Fuel tank capacity in gallons vs litres
The fuel tank capacity of a vehicle refers to the maximum amount of fuel that its fuel tank can hold. This capacity is typically measured in litres or gallons and is an important factor for drivers as it determines how far a vehicle can travel before needing to refuel.
Fuel tank capacity can be calculated by multiplying the volume of the tank by the density of the fuel. The volume of a tank is determined by its shape, with oval tanks calculated by finding the area of one end and multiplying it by the length. The results of tank volume calculations are typically given in US fluid gallons, Imperial (UK) gallons, cubic feet, metric litres, and cubic meters.
The fuel tank capacity of a Ford Fusion appears to be approximately 16.5 gallons, with some sources stating it can hold up to 18 gallons. This equates to roughly 62.46 litres to 68.14 litres, considering that 1 US gallon is equivalent to roughly 3.785 litres.
In general, smaller cars tend to have fuel tanks that hold around 12 gallons (45.42 litres) of gas, while larger cars can hold around 15 gallons (56.78 litres) or more. The average gas tank capacity falls between 38 and 76 litres, or 10 and 20 gallons.
