The 2020 Fiat 500L 1.4L 4-cyl achieves 25 MPG combined, a uniquely European approach to the small wagon. It’s designed for city practicality and maximizing interior space within a small size. Buyers choose the 500L for its charm and cargo capacity relative to its size, accepting its average fuel consumption as a trade-off.

City and highway performance

The EPA estimates the 2020 Fiat 500L 1.4L 4-cyl gets 22 MPG in the city and 30 MPG on the highway. The lower city figure is because the engine needs to work harder in stop-and-go traffic, especially when loaded. The 30 MPG highway number is achievable on longer, steady drives, but expect it to drop somewhat when encountering hills or maintaining higher speeds. The 1.4-liter’s small size requires it to rev to deliver power, especially when passing or merging onto the highway.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 Fiat 500L at exactly $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. Real-world costs could vary depending on local fuel prices, driving habits, and the percentage of city versus highway driving. Even slight variations in your driving style can change fuel consumption, possibly differing from this standardized EPA estimate.

Real-world expectations

Your real-world fuel economy will likely fluctuate, depending on driving conditions and habits. Aggressive acceleration, frequent short trips, and carrying heavy loads will all negatively impact fuel consumption. Owners who prioritize smooth acceleration, anticipate traffic flow, and minimize idling will likely see figures closer to the EPA estimates. However, don’t expect to consistently exceed 30 MPG unless you are extremely mindful of your driving habits. This is a vehicle whose engine needs to work to deliver its power.

How it compares

Compared to other small wagons and hatchbacks, the 2020 Fiat 500L’s fuel economy is average. For example, a similarly sized 2020 Kia Soul achieves up to 33 MPG highway with its base engine, while offering a more contemporary design. Even the slightly larger 2020 Mazda CX-5, in its base trim, manages 25 MPG combined, matching the 500L despite offering more space and power. Buyers opting for the 500L sacrifice fuel efficiency for its unique styling and maximized interior volume for its size.

Tips to maximize efficiency

Take advantage of the 6-speed automatic transmission. It’s designed to keep the engine operating in its most efficient range. Avoid aggressive acceleration and hard braking, allowing the transmission to shift through the gears smoothly. This will not only improve fuel economy but also extend the life of the drivetrain.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the pressure specified on the doorjamb sticker. A simple tire pressure gauge can pay for itself in fuel savings.

Minimize idling. Idling consumes fuel without covering any distance. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and the fuel saved by avoiding prolonged idling can add up over time.

Reduce weight. The 2020 Fiat 500L has a decent cargo capability, but carrying unnecessary weight reduces fuel economy. Clean out any unnecessary items from the trunk and passenger area. The lighter the vehicle, the less effort the engine needs to expend.
