2014 Ford Fiesta ST FWD: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 2014 Ford Fiesta ST FWD. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Fuel economy at a glance

These are the EPA's official ratings for the 2014 Ford Fiesta ST FWD. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 2014 Ford Fiesta ST FWD compares

The 2014 Ford Fiesta ST FWD returns 29 combined MPG. Cars in the Compact Cars class for the same model year average 27.1 MPG, which puts this car ahead of the class average by about 7%.

The most efficient car in the Compact Cars class for the 2014 model year is the Ford Focus Electric at 105 MPG. The bar chart below puts the Ford Fiesta ST FWD alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2014 model year (across all classes) returns 23.8 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2014 model year is on its own page.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for regular gasoline, which is $3.99/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 517.2 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the Ford Fiesta ST FWD

The EPA has rated the Ford Fiesta ST FWD across 6 model years, from 2014 Ford Fiesta ST FWD through 2019 Ford Fiesta ST FWD. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

Combined MPG has stayed in roughly the same range across the run, hovering close to 28 MPG.

Specifications

The 2014 Ford Fiesta ST FWD runs a 1.6-liter 4-cylinder turbocharged engine paired with a manual 6-spd, sending power through front-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

  The EPA estimates an annual fuel cost of $2,050 for the 2014 Ford Fiesta ST FWD. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade.
• What fuel does the 2014 Ford Fiesta ST FWD use?

  The EPA lists the 2014 Ford Fiesta ST FWD as running on regular gasoline. Using a different grade than the manufacturer specifies can affect fuel economy and engine longevity.
• Has the Ford Fiesta ST FWD become more fuel efficient over time?

  Combined MPG has stayed close to flat across the run. Both the earliest (2014 Ford Fiesta ST FWD, 29 MPG) and most recent (2019 Ford Fiesta ST FWD, 28 MPG) versions sit in the same range.
• How much CO₂ does the 2014 Ford Fiesta ST FWD emit?

  Tailpipe CO₂ emissions are 305 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 4,575 kilograms of CO₂.
• What is the difference between the city and highway MPG of the 2014 Ford Fiesta ST FWD?

  City driving returns 26 MPG and highway driving returns 34 MPG, a gap of 8 MPG. A spread that wide is typical of cars with conventional automatic or manual transmissions, where stop-start city traffic eats more fuel than a steady highway cruise.
• What engine is in the 2014 Ford Fiesta ST FWD?

  The 2014 Ford Fiesta ST FWD has a 1.6-liter 4-cylinder turbocharged engine (EPA description: SIDI). Smaller turbocharged engines like this one tend to deliver bigger-engine power on demand while keeping fuel economy closer to a non-turbo version of the same displacement.
