29 MPG combined probably isn’t the first thing someone thinks about when considering a 2019 Fiat 124 Spider. They’re likely more concerned with top-down thrills, Italian design, and the eager turbo four-cylinder that makes this roadster so fun. But fuel economy is still part of owning a car, and this number is reasonable for a small, sporty car that focuses on fun over pure fuel savings.

City and highway performance

The EPA further breaks down the 124 Spider’s fuel economy, estimating 25 MPG in the city and 36 MPG on the highway. That significant jump between city and highway numbers shows how much more efficient the 1.4-liter turbo engine can be when running at a constant speed and load. Stop-and-go driving, with its constant accelerations and decelerations, works the turbocharger harder and keeps the engine away from its optimal efficiency. On the open road, the 124 Spider settles into a relaxed cruise, needing less boost and therefore less fuel to maintain speed. The six-speed automatic transmission also helps highway efficiency, letting the engine run at lower RPMs than with fewer gears. Manual transmission versions will have slightly different MPG results depending on the driver.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,000 for the 2019 Fiat 124 Spider. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and the national average fuel price at the time. Your actual fuel costs will vary based on how much you drive, the type of driving, and the price of gasoline in your area. Someone who mainly uses their 124 Spider for weekend trips will likely spend far less than $2,000 per year, while a driver who commutes long distances in heavy traffic might spend more. This number gives a useful way to compare the 124 Spider’s running costs to other vehicles, especially since this vehicle needs premium gasoline.

Real-world expectations

While the EPA estimates give a standard, remember that real-world fuel economy will always be different. Aggressive driving, frequent short trips, and even things like tire pressure and ambient temperature can all change the MPG you get. Many 124 Spider owners report numbers close to the EPA estimates in mixed driving, but using the turbocharger often will lead to lower numbers. This car is fun to drive hard, and enjoying that sometimes is part of owning it.

How it compares

Compared to similar cars, the 2019 Fiat 124 Spider is in a good spot. The Mazda MX-5 Miata, which shares its platform with the 124 Spider, does a little better, getting 29 MPG combined with the automatic transmission, close to the 124’s numbers, though it doesn’t require premium gasoline. When comparing all 124 MPG across all years it’s clear the fuel economy numbers remain relatively consistent. A Nissan 370Z Roadster, while offering much more power, sees a big drop, hitting just 20 MPG combined. Even front-wheel-drive sport compacts like the VW GTI (28 MPG combined) don’t always offer a big advantage. Part of the 124 Spider’s appeal is its classic roadster layout and rear-wheel-drive, which those front-wheel-drive options don’t have.

Tips to maximize efficiency

Take advantage of the car’s lightweight build. The 124 Spider doesn’t need much throttle to get moving, so avoid heavy acceleration from a stop. Gentle inputs will help keep the turbocharger from constantly working and using extra fuel. Proper weight distribution of the vehicle will also improve performance and fuel efficiency.

Keep consistent tire pressures. The 124 Spider’s small, lightweight tires are sensitive to being underinflated, which increases rolling resistance and lowers fuel economy. Check your tire pressures often, especially before long drives.

Think about using a lighter weight oil. Many modern engines work better with thinner oils. Check your owner’s manual to see if using an oil with a lower viscosity is an option. Because the 124 Spider needs premium gasoline, saving MPG in other ways makes even more economic sense.

Plan your routes. Avoid areas known for heavy traffic or lots of stoplights if you can. Choosing routes with more consistent speeds will keep the engine running most efficiently.
