24 MPG combined is the compromise with the 2018 Fiat 500X AWD 2.4L. It’s not the most fuel-efficient, but it’s not particularly thirsty for its class. Understanding that number is important for anyone considering this quirky Italian crossover. The 500X targets a specific buyer: someone who wants European styling and available all-wheel drive in a subcompact package. Fuel economy is a consideration, but often it’s less important than aesthetics and practicality.

City and highway performance

The EPA estimates the 2018 Fiat 500X AWD 2.4L at 21 MPG in the city and 29 MPG on the highway. The lower city figure reflects stop-and-go traffic, where the 2.4L engine works harder to move the 500X, which is relatively heavy for its size. The 9-speed automatic transmission offers a wide range of ratios for efficiency, but sometimes searches for the right gear in urban driving, impacting fuel consumption. However, on the open road, the 500X cruises more efficiently, allowing the engine to operate in its best range and delivering closer to the 29 MPG highway rating.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2018 Fiat 500X AWD 2.4L at $1,800. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway, using the national average fuel price. Your actual fuel costs will vary depending on your driving habits, roads, and local fuel prices. Drivers who spend more time in stop-and-go traffic, or accelerate quickly, will likely exceed this estimate. And higher fuel prices in your area will increase your annual fuel expense.

Real-world expectations

The EPA estimates offer a baseline, but real-world fuel economy for the 2018 Fiat 500X AWD 2.4L can vary. Owners report figures slightly below the combined 24 MPG rating, particularly in areas with difficult terrain or traffic. Aggressive driving, short trips in cold weather, and using the air conditioning can negatively impact fuel economy. Smooth acceleration, anticipating traffic, and regular maintenance may result in figures closer to, or even above, the EPA estimates. Your driving style is key to maximizing fuel efficiency in the 500X.

How it compares

The fuel economy of the 2018 Fiat 500X AWD 2.4L is in the middle of the subcompact crossover segment. The Mazda CX-3 AWD gets a better 29 MPG combined, making it a more fuel-efficient choice. The Jeep Renegade, which shares a platform with the 500X but offers a slightly different driving experience, gets a similar 24 MPG combined with its 2.4L engine and AWD. A front-wheel drive Honda HR-V boasts 28 MPG combined. These comparisons are important for buyers considering the 500X, especially if fuel costs are a major concern. Some may sacrifice a few MPG for the Fiat’s styling and available AWD.

Tips to maximize efficiency

The 2.4L engine in the 500X responds well to smooth acceleration. Avoid sudden bursts of speed, instead, gradually increase your throttle. This will save fuel, and reduce wear on the engine and transmission. Using cruise control on the highway can maintain a consistent speed, minimizing fuel consumption.

Regular maintenance is essential for fuel economy. Make sure your tires are properly inflated, since low tire pressure increases rolling resistance and reduces MPG. Keeping up with oil changes and scheduled maintenance will help the engine run efficiently. Check all Fiat fuel economy data to see maintenance schedules and owner reviews.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines restart quickly, and you’ll save fuel by avoiding unnecessary idling. This is important in urban environments where idling is more common.

Consider the weight you’re carrying. Excess cargo adds to the vehicle’s weight, which increases fuel consumption. Remove unnecessary items from the trunk or backseat to lighten the load. This can make a difference, especially on longer trips, and view 500 MPG across all years of the model.

Be mindful of your driving environment. Driving in hilly terrain or windy conditions can reduce fuel economy. If possible, plan your routes to avoid these conditions, or adjust your driving. Anticipating traffic and choosing the most efficient route can also save you time and money.
