The Ford Fiesta ST offers impressive fuel economy for a performance-oriented hatchback. Recent real-world user data suggests an average of about 29-30 miles per gallon (mpg), with some variance depending on model year and driving conditions[1]. Specifically, the 2020 Fiesta ST averaged 29.7 mpg based on community fuel-up data, while previous model years from 2014 to 2019 typically range from 27 to 29.7 mpg[1].
The official EPA figures rate the Fiesta ST at 26 mpg city, 35 mpg highway, and 29 mpg combined for the 2014–2019 models equipped with a 1.6L EcoBoost turbo engine and six-speed manual transmission[2]. For the 2019 model, EPA values are 25 mpg city, 32 mpg highway, and 28 mpg combined[5]. Real-world testing often yields 31 to 32 mpg in mixed driving, with highway-only figures hitting up to 38 mpg[3][6][8].
Individual owner reports support these numbers, with several reporting averages in the 35–40 mpg range on longer, steady drives[7]. Observed consumption can vary based on driving style, route, and load. For instance, publication reviews have recorded 38 mpg on highway tests, beating EPA estimates[3][8].
In summary, the Ford Fiesta ST generally consumes 3.3 to 3.9 gallons per 100 miles, translating to efficient fuel use for a small, high-output turbo car[5]. Both regular and premium unleaded can be used, but some owners recommend using premium for optimal performance[7].
