27 MPG combined is arguably the least interesting thing about the 2018 Fiat 500 1.4L. This isn’t a car bought for hyper-miling, efficiency spreadsheets, or bragging rights. It’s a style statement, a city runabout, a personality on wheels. Fuel economy is a factor, but it’s far down the list for buyers who are smitten with the 500’s retro charm and small size. They’re willing to accept acceptable mileage for Italian flair and easy parking. These are the people who value individuality over pure economy.

City and highway performance

The EPA estimates 24 MPG in the city and 32 MPG on the highway for the Fiat 500 with the 1.4L four-cylinder engine and six-speed automatic transmission. The city figure reflects the stop-and-go nature of urban driving, where this car shines. Its small size and nimble handling make it a joy to dart through traffic.

The highway number, while decent, acknowledges that the 500 isn’t designed for long-distance cruising. The short wheelbase and light weight mean you’ll feel every expansion joint and crosswind. Buyers who frequently drive long distances might want to consider other, larger vehicles.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Fiat 500 1.4L at $2,150. This figure is calculated based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Individual fuel costs will vary depending on driving habits, local fuel prices, and how often you use the air conditioning. However, $2,150 provides a benchmark for comparing the 500’s running costs to those of other vehicles. You can see all Fiat fuel economy data on this site.

Real-world expectations

While the EPA provides a useful standardized estimate, real-world fuel economy can vary considerably. Aggressive driving, frequent short trips (which don’t allow the engine to reach optimal operating temperature), and carrying extra weight can all negatively impact fuel efficiency. Conversely, gentle acceleration, consistent speeds, and proper tire inflation can help you achieve or even exceed the EPA estimates.

Owners often report that the city MPG can dip below 24 if they’re constantly stuck in heavy traffic, while highway numbers can surpass 32 MPG when maintaining a steady speed on relatively flat terrain.

How it compares

Compared to other small cars, the 2018 Fiat 500’s fuel economy is adequate. The Honda Fit, achieved 31 MPG combined with its automatic transmission. The Toyota Yaris was rated at 32 MPG combined, offering superior economy at a similar price point. Some larger vehicles, like the Mazda3 (28 MPG combined in its base trim), offered comparable or better fuel economy while providing more space. The Mini Cooper delivered around 28 MPG combined, making it a slightly more efficient alternative. However, the Fiat 500 has a unique Italian design and smaller footprint, which appeals to buyers prioritizing those qualities over fuel efficiency. You can also look at the 500 MPG across all years to see how this model compares.

Tips to maximize efficiency

Anticipate traffic flow and avoid sudden acceleration and braking. The Fiat 500’s small engine works best when driven smoothly. Minimize rapid bursts of speed, especially in city driving, to conserve fuel. Use the air conditioning sparingly, as it places a significant load on the engine and decreases fuel economy. Open the windows when appropriate to avoid using the AC. The 500’s small cabin cools down quickly when air can circulate.

Ensure your tires are properly inflated. Underinflated tires create more rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level, which can be found on the sticker inside the driver’s side door jamb. Even a few PSI below the recommended pressure can noticeably impact fuel consumption. Also, use the correct grade and spec of oil for your car.

Reduce unnecessary weight in the vehicle. Carrying extra cargo adds to the vehicle’s weight, forcing the engine to work harder and consume more fuel. Remove any items from the trunk or back seat that aren’t essential, such as sports equipment, tools, or other heavy objects. Weight management can add up to small but meaningful fuel savings.

Consider using cruise control on the highway. Maintaining a consistent speed can help optimize fuel economy on long drives. Cruise control minimizes fluctuations in speed, preventing unnecessary acceleration and braking. Remember to disengage cruise control in heavy traffic.
