How big is the gas tank on a 2017 Ford Fusion?

The 2017 Ford Fusion’s gas tank size depends on the model and trim level. Hybrids may hold 14 gallons of fuel, but gas-powered models have a capacity of 16.5 or 18 gallons.

Gas-powered 2017 Ford Fusions

Standard 2017 Ford Fusion sedans will have either 16.5-gallon or 18-gallon tanks. The difference is in the type of drivetrain in each vehicle.
All-wheel drive (AWD) vehicles will have an 18-gallon tank. This includes vehicles with the 2.0L four-cylinder turbo engine or 2.7L V6 twin-turbo engine. 
Having AWD requires more power than front-wheel drive (FWD) because power is being sent to the front and back, rather than just to the front of the car.
Standard FWD 2017 Ford Fusions have 16.5-gallon tanks. This only includes vehicles with the 2.5L four-cylinder engine. FWD demands less energy because power is only being sent to the front wheels, not to the rear wheels.

Hybrid 2017 Ford Fusions

Since hybrid cars run partially on electricity, their gas tanks are a little different. Hybrid Ford Fusions come with smaller 14-gallon gas tanks to accommodate this difference.
However, the 2017 Ford Fusion Energi (a plug-in hybrid) is capable of traveling up to 22 miles on electric power alone. As such, the smaller fuel tank seems sufficient.

How to check your Ford Fusion’s gas tank size

If you’re still not sure about your 2017 Ford Fusion’s gas tank size, no need to worry! There are a few simple ways to determine your car’s fuel capacity:

Measure your gas tank

Yup, you can use basic math to figure out your car’s fuel capacity. To do it, grab a measuring tape and record the length, width, and height of your car’s fuel tank. 
Multiply those three figures together to get the volume of the gas tank. Then, divide that number by 231, since that is the number of cubic inches in a gallon.

Drive your car to empty, then fill the tank

This might not be the most scientific way to figure out your car’s fuel capacity, but it’s effective enough. 
Simply drive your Ford Fusion until your fuel gauge reads E, then go to the gas station. The number of gallons it took to fill your car will appear on the fuel pump display—and this is your car’s approximate fuel capacity!

Check your owner’s manual

Details about your car can usually be found in your owner’s manual. Leaf through your manual or check the index for terms like fuel tank capacity to find the information you want.
