The 2018 Ford Fiesta ST, with its 1.6L turbocharged engine and a smooth six-speed manual, gets a combined fuel economy rating of 29 MPG. This number isn’t going to win any hypermiling competitions, nor will it persuade buyers focused on saving every drop of gas. For the enthusiast seeking an affordable and fun hot hatch, this number is an acceptable trade-off for the Fiesta ST’s playful performance and undeniable charm.

City and highway performance

Looking at the EPA numbers, the 2018 Fiesta ST gets 26 MPG in the city and 33 MPG on the highway. The city figure shows the car’s eagerness to dart around town, the turbocharger responding instantly. Stop-and-go urban driving won’t reward a light foot. The 33 MPG highway rating shows the Fiesta ST’s well-chosen gear ratios, allowing it to cruise comfortably and efficiently at higher speeds. You can easily switch between fuel-sipping highway mode and backroad-carving exuberance, which shows the car’s balanced engineering.

Annual Fuel Cost

The EPA estimates that the annual fuel cost for the 2018 Ford Fiesta ST is $1,500. This is based on driving 15,000 miles per year, using the national average fuel price. Note that this is an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use (premium fuel is often recommended for optimal performance), and local fuel prices. A driver who spends more time in city traffic will likely see a higher annual fuel cost than someone who primarily drives on the highway. Despite the variables, the $1,500 figure provides a useful benchmark for budgeting and comparison.

Real-world expectations

The EPA provides a standardized benchmark, but real-world fuel economy often differs. Fiesta ST owners report figures that are either slightly above or below the EPA estimates, depending on how they drive. Those who embrace the ST’s sporty nature and frequently explore its turbocharged powerband will likely see MPG figures closer to the low end of the range, perhaps even dipping below 26 MPG in aggressive city driving. However, drivers who adopt a more conservative driving style and prioritize fuel efficiency can potentially achieve highway numbers closer to 35 MPG or even higher. Consistent use of cruise control on the highway will yield the best results. The driver determines the final MPG figure.

How it compares

The 2018 Ford Fiesta ST is competitive among performance-oriented subcompacts. Consider the MINI Cooper S, a rival known for its playful handling and energetic engine. The Cooper S typically gets around 26 MPG combined, slightly behind the Fiesta ST. The Volkswagen GTI, a more refined hot hatch, manages around 28 MPG combined in its base trim, nearly matching the Fiesta ST. The Honda Civic Si delivers around 32 MPG combined. These numbers show the Fiesta ST’s position as a reasonably fuel-efficient choice but some competitors offer slightly better numbers. The Fiesta ST is has a lower price than its rivals, making its blend of performance and economy appealing for enthusiasts who still want fun behind the wheel. Always compare all Ford fuel economy data before making a decision.

Tips to maximize efficiency

Pay close attention to tire pressure. The Fiesta ST’s performance-oriented tires are designed to provide optimal grip at a specific pressure. Keeping the recommended pressure, found on the door placard, minimizes rolling resistance, which helps to improve fuel economy. Regularly check and adjust your tire pressure, especially when the temperature changes.

Anticipate traffic flow. The Fiesta ST, with its manual transmission, rewards drivers who are actively engaged. By anticipating traffic conditions and adjusting your speed, you can minimize unnecessary acceleration and braking, which consume extra fuel. Coasting to red lights, rather than braking hard at the last second, can make a difference.

Limit idling. The turbocharged engine in the Fiesta ST is most efficient when it’s operating at its optimal temperature. Excessive idling wastes fuel. If you’re going to be stopped for more than a minute or two, it’s generally more efficient to turn off the engine.

Shift smoothly and deliberately. The Fiesta ST’s six-speed manual transmission is fun to use when shifted precisely, but sloppy or rushed shifts can negatively impact fuel economy. Focus on smooth gear changes and avoid “powershifting” unless you’re on a racetrack. The FIESTA MPG across all years is consistent because of its excellent powertrain.
