The gas mileage of the Ford Focus varies depending on transmission type, year and fuel source, but most models have combined city and highway miles per gallon (mpg) ratings between 22 and slightly more than 30. Some Ford Focus models operate using standard gasoline, while others use a combination of gas and electricity or gas and ethanol. Models using standard gasoline include the Ford Focus FWD and Ford Focus FWD FFV; versions with manual transmissions average 23 to 26 mpg in the city, and between 32 and 36 mpg on the highway, while those with automatic transmissions average 27 mpg in the city and 31 mpg on the highway.
Ford produces the Focus in several body types and trims, including a sedan and hatchback version. The sedan comes in an S, SE and Titanium model while the hatchback comes in a Titanium, Electric and ST version. These cars have varying gas mileage, which ranges from a low of 23 mpg in the city, found in the ST Hatch, to more than 100 mpg in the city in the Electric Hatch.
In addition to the standard FWD, Ford produces the Focus in a flex fuel version, which it calls the FFV. These cars, with automatic transmissions, average 20 mpg in the city and may reach more than 40 mpg on the highway, depending on whether they use gasoline or a gasoline-ethanol blend. FFVs with manual transmissions average between 19 mpg and 26 mpg in the city, and 26 mpg to 36 mpg on the highway.
