31 MPG combined is respectable for the 2018 Ford Fiesta with its 1.6L four-cylinder engine, and it’s why people who prioritize economy choose this subcompact. It’s not trying to be a sports car, and its interior isn’t exactly luxurious. Instead, this generation of Fiesta delivers reliable, efficient transportation in a small, affordable package where fuel economy is important.

City and highway performance

The EPA estimates for the 2018 Fiesta FWD with the 1.6L engine and automatic transmission are 27 MPG in the city and 37 MPG on the highway. The city figure reflects the stop-and-go driving conditions associated with urban environments, scenarios where the Fiesta’s lightweight design helps claw back a few MPGs. The highway figure illustrates the engine’s capability to cruise efficiently at steady speeds.

While 37 MPG might not sound groundbreaking, remember that this isn’t a hybrid or a diesel, it’s a small, gasoline-powered car designed for affordability first.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Ford Fiesta at $1,400. This estimate is based on driving 15,000 miles per year and using the national average fuel price. Your actual fuel costs will change depending on how much you drive and the price of gasoline where you live.

However, the $1,400 figure helps compare the Fiesta’s fuel costs against other vehicles. It’s a tangible number that helps potential buyers understand the long-term cost of ownership beyond the initial purchase price.

Real-world expectations

While EPA estimates provide a standardized measure, real-world fuel economy can vary. Factors like driving style, traffic conditions, and even tire pressure can influence your MPG. Aggressive acceleration and hard braking will significantly reduce fuel efficiency. Similarly, driving in heavy traffic with frequent stops and starts will lower your average MPG.

With a mindful driving style and proper maintenance, owners can reasonably expect to achieve figures close to the EPA estimates. Some owners report highway numbers exceeding 40 MPG on long trips at constant speeds, showing what this Fiesta can do when driven with fuel efficiency in mind.

How it compares

The 2018 Fiesta’s fuel economy stacks up favorably against some of its competitors, while falling slightly behind others. For example, the contemporary Honda Fit, known for its versatility and impressive cargo space, gets around 33 MPG combined. The Toyota Yaris, another fuel-sipping subcompact, manages roughly 32 MPG combined. The Nissan Versa, often lauded for its affordability, returns about 34 MPG combined.

While some of these rivals show a slight edge in combined MPG, the Fiesta often comes in at a lower price point. For a broader perspective, you can view all Ford fuel economy data, and even dive deeper into FIESTA MPG across all years.

Tips to maximize efficiency

The 1.6L Fiesta responds well to gentle throttle inputs. Avoid aggressive acceleration from a standstill and try to anticipate traffic flow to maintain momentum. The automatic transmission is programmed for efficiency, but using a lighter foot overall will make a noticeable difference at the pump.

Tire pressure is critical, and often overlooked. Refer to the sticker on the driver’s side doorjamb for the recommended tire pressure. Inflated tires not only improve fuel economy but also enhance handling and tire life. Check your tire pressure at least once a month, especially during temperature changes.

Minimize unnecessary weight. Carrying extra cargo in the trunk or back seat reduces fuel economy. Remove any items you don’t need, like sports equipment or tools, to reduce the load on the engine. Small changes in weight can add up, particularly in a small car like the Fiesta.

Regular maintenance is essential for optimal fuel efficiency. Ensure your engine is properly tuned, and replace air filters and spark plugs according to the manufacturer’s recommendations. A well-maintained engine runs more efficiently, burning fuel more completely and delivering better MPG.

Consider using cruise control on long highway trips. Maintaining a constant speed eliminates the fluctuations in throttle input that occur during manual driving, resulting in improved fuel economy. It’s a simple way to maximize your MPG on the open road, extracting the most efficiency from the 1.6L engine.
