29 MPG combined is an acceptable figure for the 2017 Fiat 124 Spider, but realistically, nobody buys this car for its outstanding fuel efficiency. They buy it for the open-top experience, the Italian styling, and the relative affordability of a roadster. Fuel economy is secondary, a necessary evil on the path to wind-in-your-hair motoring.

City and highway performance

The EPA estimates for the 2017 Fiat 124 Spider, equipped with its 1.4L turbocharged four-cylinder engine and six-speed automatic transmission, break down to 25 MPG in the city and 36 MPG on the highway. The city figure reflects the realities of stop-and-go driving, where the small turbo engine works harder and efficiency suffers. The highway number, however, is more respectable, especially on longer road trips where the engine can settle into a relaxed cruising rhythm. Drivers who prioritize backroads over interstates will naturally see results closer to the city estimate.

Annual fuel cost

The EPA estimates that the 2017 Fiat 124 Spider will cost approximately $2,000 per year in fuel. This is based on driving 15,000 miles annually, using the EPA’s fuel economy ratings, and assuming national average fuel prices. Keep in mind that actual costs will vary depending on individual driving habits and the prevailing price of gasoline in your area. Aggressive driving, excessive idling, and a heavy foot will all impact that $2,000 figure, likely in the upward direction.

Real-world expectations

While the EPA ratings provide a useful baseline, your personal fuel economy with the 124 Spider will inevitably differ. Vehicles like this one, that are geared towards driving enthusiasts, tend to see lower real-world numbers, simply because drivers are more inclined to explore the engine’s performance capabilities. Expect to see figures hovering around the low 20s in the city if you enjoy spirited acceleration. Highway numbers are generally easier to replicate, but consistent high-speed driving will naturally decrease efficiency. Across all years, you can explore 124 MPG data. The turbocharger spools up easily, and it can be tempting to use the available power.

How it compares

Compared to its closest competitor, the Mazda MX-5 Miata, the 124 Spider’s fuel economy is close but slightly behind the Miata. A 2017 Mazda MX-5 with the 2.0L engine and automatic transmission achieves 26 MPG city and 35 MPG highway. Some may find this acceptable in order to purchase the Fiat styled version of the same vehicle. These differences mean that you should look at all Fiat fuel economy data before making a decision.

Tips to maximize efficiency

Avoid hard acceleration. The 1.4L turbo engine is responsive, but repeatedly demanding maximum boost will take a toll on your fuel economy. Smooth, progressive acceleration is key to extracting the most miles from each gallon.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressures regularly and inflate them to the recommended levels, found on the door placard.

Minimize idling. Letting the engine idle for extended periods wastes fuel. If you’re stopped for more than a minute, turn off the engine. The 124 Spider doesn’t offer engine start-stop, so managing idling is entirely up to the driver.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long trips. Be mindful of hills and traffic conditions, as cruise control can sometimes be detrimental in dynamic situations.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine is running optimally. A well-maintained engine is an efficient engine.
