The 2017 Ford Fiesta, equipped with the 1.6L four-cylinder engine and automatic transmission, gets a respectable 31 MPG combined. This isn’t groundbreaking, but it’s perfectly aligned with the Fiesta’s mission: providing affordable, efficient, and fun transportation for city dwellers, first-time car buyers, and anyone prioritizing value and nimble handling over outright space or luxury. It’s a car buyers choose deliberately, accepting certain compromises in exchange for low running costs and an engaging driving experience in crowded urban environments.

City and highway performance

The EPA estimates the 2017 Fiesta at 27 MPG in the city and 37 MPG on the highway. The city figure is perhaps more crucial to understanding the Fiesta’s appeal. This is a car designed to thrive in stop-and-go traffic, zipped into tight parking spaces, and maneuvered through congested streets with ease. The 27 MPG city rating demonstrates its ability to remain relatively frugal even under those demanding conditions. The 37 MPG highway number isn’t class-leading, but it proves the Fiesta won’t punish you on longer journeys. It’s perfectly capable of weekend road trips, maintaining comfortable speeds while keeping fuel stops to a minimum.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Ford Fiesta at exactly $1,400. This figure is based on driving 15,000 miles per year and using the national average fuel price. Individual spending will vary depending on driving habits and fuel prices in a particular area, but $1,400 provides a solid baseline. For budget-conscious buyers, knowing that their annual fuel expenditure will likely stay within that ballpark is crucial. They’re not expecting hybrid levels of efficiency, but they’re demanding predictability and value, and the Fiesta delivers on both counts.

Real-world expectations

While the EPA estimates offer a good benchmark, real-world MPG often deviates. Aggressive driving, carrying heavy loads, and prolonged idling can all negatively impact fuel economy. However, the 2017 Fiesta’s engine is relatively responsive, so you shouldn’t have to drive it hard to keep up with normal traffic speeds. And given the Fiesta’s small size and limited cargo capacity, it’s unlikely to be consistently overloaded. A sensible driver should be able to achieve MPG close to EPA estimates, with some even exceeding the 31 MPG combined number with mindful driving habits.

How it compares

The 2017 Honda Fit, another popular subcompact, achieves a slightly better EPA rating, achieving 33 MPG combined in its automatic transmission configuration. The Hyundai Accent, another key competitor in this segment, also achieves a combined EPA-estimated MPG of 31 when equipped with its automatic transmission—matching the Fiesta. This comparison matters because these vehicles cater to a very similar audience. Buyers are cross-shopping based on price, features, and, fuel economy. A single MPG difference might seem negligible, but it can influence the final decision, particularly for drivers who rack up significant mileage.

Tips to maximize efficiency

Avoid aggressive acceleration. The Fiesta’s 1.6L engine is peppy enough, but stomping on the gas pedal will quickly drain your fuel tank. Gentle acceleration and anticipating traffic flow will allow you to maintain a steady speed and minimize fuel consumption.

Keep your tires properly inflated. Underinflated tires create more rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended PSI found on the driver’s side door jamb. This is especially important in colder weather, when tire pressure naturally decreases.

Reduce idling time. Idling wastes fuel and produces unnecessary emissions. If you’re going to be stopped for more than a minute or two, it’s better to turn off the engine. This is especially relevant for city drivers who spend a significant amount of time waiting at traffic lights or in congested areas.

Regular maintenance is key to efficiency. Keeping your engine properly tuned and your air filter clean can improve fuel economy. Follow the recommended maintenance schedule in your owner’s manual. Old or dirty spark plugs, for example, can negatively impact combustion, leading to reduced MPG. Don’t neglect these small, but essential, services.

Consider using cruise control on the highway. Maintaining a consistent speed can help optimize fuel economy. However, be mindful of using cruise control in hilly terrain, as the Fiesta’s transmission might downshift frequently, negating some of the benefits.
