29 MPG combined isn’t going to win any hypermiling competitions, but it’s perfectly respectable for the 2017 Ford Fiesta ST. This isn’t a car someone buys for its outright fuel sipping abilities; it’s for the smile it puts on your face carving up a backroad. It offers hot hatch thrills in a compact package. The efficiency simply doesn’t detract from that mission.

City and highway performance

The EPA estimates for the Fiesta ST break down to 26 MPG in the city and 33 MPG on the highway. That healthy highway figure shows its usability as a daily driver. It won’t punish you on longer trips, even if it occasionally encourages spirited driving. The city number, while lower, is still reasonable considering how the car is likely to be driven. Stop-and-go traffic might dip below the EPA estimate, especially if you enjoy exploiting the turbocharger’s boost between traffic lights.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 Ford Fiesta ST is $1,500. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that premium fuel is recommended for optimal performance, so that figure could fluctuate depending on location and the price of premium gas. However, even with premium fuel, $1,500 represents a manageable expense in the context of overall car ownership.

Real-world expectations

While the EPA estimates provide a solid baseline, real-world fuel economy will always vary depending on driving style and conditions. A lead foot will undoubtedly push the MPG lower, as will frequent short trips where the engine doesn’t have a chance to fully warm up. A more conservative driver who anticipates traffic and avoids aggressive acceleration could potentially exceed the EPA estimates, especially on longer highway journeys. You’ll likely find yourself somewhere in between, perhaps averaging closer to the low 30s in mixed driving if you prioritize efficiency.

How it compares

Competitors like the Volkswagen GTI offer similar levels of performance, but with slightly better fuel economy. A 2017 GTI S with the manual transmission achieves an EPA-estimated 24 MPG city and 34 MPG highway. The Honda Civic Si, another popular choice in the segment, typically fares a bit better, reaching 28 MPG city and 38 MPG highway. For buyers prioritizing ultimate efficiency, those few MPGs can make a difference, but the Fiesta ST counters with its uniquely playful handling and distinctive character. Those choosing a MINI Cooper S won’t do much better, since that achieves 26 MPG city and 32 MPG highway.

Tips to maximize efficiency

The Fiesta ST’s turbocharged engine responds well to smooth, consistent throttle inputs. Avoid abrupt acceleration and unnecessary revving, especially when the engine is cold. A gentle touch will not only improve fuel economy but also extend the life of wear items like tires and brakes.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, which negatively impacts fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level, found on the sticker inside the driver’s side door jamb. Even a few PSI can improve MPG.

Minimize unnecessary weight. Hauling around extra cargo in the trunk or backseat adds weight and reduces fuel economy. Remove any items you don’t need on a regular basis. Every pound counts, especially in a small car like the Fiesta ST.

Plan your routes to avoid stop-and-go traffic whenever possible. Constant acceleration and braking consume more fuel than maintaining a steady speed. Using navigation apps to identify and avoid congested areas can significantly improve your MPG.

Resist the temptation to constantly engage the turbocharger for maximum power. While the Fiesta ST is undoubtedly fun to drive aggressively, dialing back the enthusiasm can make a noticeable difference at the pump. Reserve the full boost for truly exciting driving situations and enjoy the fuel savings the rest of the time.
