24 MPG combined isn’t going to win any awards, especially in the subcompact crossover segment. But for those drawn to the 2017 Fiat 500X AWD with the 2.4L four-cylinder engine, it’s a price many are willing to pay for the distinctive Italian styling and all-weather confidence. This isn’t a vehicle bought by hypermilers; it’s a fashion statement and a practical choice for urban dwellers who occasionally venture onto unpaved roads. It’s also a nod to those who appreciate European design flair. The 500X driver prioritizes personality over pure efficiency, but that doesn’t mean fuel economy is irrelevant. They just accept it as part of the broader package.

City and highway performance

The EPA estimates suggest 21 MPG in the city and 29 MPG on the highway for the 2017 Fiat 500X AWD with the 2.4L engine. Critically, the highway figure is where many drivers will likely fall short. The 9-speed automatic transmission, while offering abundant gears, can often hunt between ratios, particularly at higher speeds or when encountering even slight inclines. Because of this, expect the highway mileage to be very sensitive to your right foot. City driving, on the other hand, can sometimes come closer to the EPA estimate, especially if you avoid aggressive acceleration. Drivers using the 500X primarily for short commutes and errands around town may find the MPG acceptable.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Fiat 500X AWD 2.4L at $1,800 per year. This calculation is based on driving 15,000 miles annually, using a blend of city and highway driving, and assumes the national average fuel price at the time of testing. Individual costs will vary based on driving habits, local fuel prices, and the actual percentage of city versus highway miles driven. For example, someone who drives primarily in stop-and-go city traffic and regularly uses premium fuel could expect a significantly higher annual fuel bill.

Real-world expectations

While the EPA numbers are a useful starting point, real-world fuel economy for the 2017 Fiat 500X AWD often falls slightly short of the official figures, especially in mixed driving conditions. Owners often report averages closer to 22-23 MPG combined, with highway figures hovering in the mid-to-high 20s. Factors such as climate, tire pressure, and cargo weight can all influence fuel consumption. Aggressive driving habits, such as frequent acceleration and hard braking, can significantly impact fuel economy. Keeping up with routine maintenance, including oil changes and tire rotations, can help maintain optimal fuel efficiency.

How it compares

The Fiat 500X exists in a competitive segment. Consider the Mazda CX-3, which offers a more engaging driving experience and superior fuel economy, managing 29 MPG combined in AWD guise. Then there’s the Honda HR-V, known for its practicality and fuel efficiency. It achieves an EPA-estimated 28 MPG combined with AWD. Another option is the Subaru Crosstrek, delivering both standard all-wheel drive and strong fuel efficiency, with some models rated as high as 29 MPG combined. These competitors highlight the 500X’s relative disadvantage in fuel economy, which becomes a more prominent consideration for buyers who aren’t heavily swayed by the Fiat’s unique aesthetics. Drivers who prioritize MPG above all else might find more options within the segment, but those with a preference for Italian design and willing to accept a slight penalty at the pump will still find the 500X appealing. You can also compare 500 MPG across all years to the 500X and see the specific differences model-by-model.

Tips to maximize efficiency

The 2.4L engine in the 500X responds well to smooth, deliberate acceleration. Avoid sudden bursts of speed when possible. Gentle throttle inputs will help the transmission stay in higher gears, reducing fuel consumption.

Tire pressure plays a critical role in fuel efficiency. Regularly check and maintain the recommended tire pressure as listed on the driver’s side doorjamb. Under-inflated tires increase rolling resistance, leading to lower MPG. Even a marginal increase in tire pressure can have a positive impact.

Minimize unnecessary weight in the vehicle. Excess cargo adds to the overall load, forcing the engine to work harder and consume more fuel. Remove any items you don’t need on a regular basis.

Plan routes strategically to avoid stop-and-go traffic. Congestion significantly reduces fuel economy as the engine idles and the vehicle accelerates frequently. Use navigation apps to identify and navigate around congested areas whenever possible. When idling for extended periods, consider turning off the engine.
