28 MPG combined is an acceptable, if unremarkable, figure for the 2018 Fiat 500 X 1.4L 4-cyl. Critically, this small crossover earns its fuel economy while also delivering a unique Italian flair and available all-wheel drive, qualities buyers prioritize over pure efficiency. People don’t buy a 500 X for class-leading MPG; they buy it because they want a distinctive, fun-to-drive vehicle that won’t break the bank at the pump.

City and highway performance

The 2018 Fiat 500 X equipped with the 1.4L turbocharged four-cylinder and manual transmission achieves an EPA-estimated 25 MPG in the city and 33 MPG on the highway. The relatively small difference between city and highway figures suggests a powertrain that is consistently efficient, avoiding the significant MPG drops seen in larger vehicles struggling under stop-and-go conditions. The turbocharger provides ample power in the low-to-mid RPM range, allowing for relaxed city driving, while the sixth gear in the manual transmission helps keep RPMs low on the highway for optimized fuel consumption. Drivers willing to embrace the manual transmission will find the fuel economy aligns closely with the EPA estimates, but expect a slight dip in real-world MPG if you spend most commutes in bumper-to-bumper traffic.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Fiat 500 X 1.4L 4-cyl to be $2,050. This figure is based on driving 15,000 miles per year and using national average fuel prices at the time of calculation. Of course, the actual amount you spend on fuel will vary depending on your driving habits, the type of roads you typically drive on, and the prevailing fuel prices in your area. Aggressive driving and a heavy reliance on boost from the turbo will certainly increase fuel consumption beyond the EPA’s estimate. For shoppers considering other model years, examining 500 MPG across all years can offer further insight.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy for the 2018 Fiat 500 X 1.4L can fluctuate. Drivers who predominantly drive in the city with frequent stops and starts might see figures closer to 23-24 MPG. Conversely, those who stick to highway driving and maintain a steady speed can often achieve or even slightly surpass the EPA’s 33 MPG rating. The smaller fuel tank in the 500 X means more frequent trips to the gas station, highlighting even minor MPG differences.

How it compares

The 2018 Fiat 500 X’s fuel economy is competitive within its class, but not class-leading. For example, the front-wheel drive Honda HR-V achieves 28 MPG combined (25 city/31 highway) with its CVT transmission, offering a similar overall MPG figure with a slightly more efficient highway rating. The Mazda CX-3, known for its sporty driving dynamics, boasts an EPA-estimated 29 MPG combined (27 city/32 highway) in its front-wheel drive configuration. Jeep Renegade models equipped with the base engine achieve 24 MPG combined, a meaningful difference for drivers sensitive to savings at the pump. These comparisons are particularly relevant to buyers cross-shopping for style, size, and price within the subcompact crossover segment. For consumers interested in the broader Fiat lineup, all all Fiat fuel economy data is readily available.

Tips to maximize efficiency

Take advantage of its lightweight design. The 500X isn’t a heavy vehicle, so avoid carrying unnecessary cargo that adds extra weight and reduces fuel efficiency. Clear out the trunk and backseat of any items you don’t need.

Master the manual transmission. Smooth and deliberate shifting is key to maximizing fuel economy with the manual transmission. Avoid aggressive acceleration and try to anticipate traffic flow to minimize unnecessary gear changes.

Monitor tire pressure regularly. Underinflated tires create more rolling resistance, which reduces fuel efficiency. Check your tire pressure at least once a month and ensure they are inflated to the recommended level indicated on the sticker located on the driver’s side doorjamb.

Use cruise control on the highway. Maintaining a constant speed on the highway helps to optimize fuel consumption. Engage cruise control whenever possible to avoid fluctuations in speed that can waste fuel.

Consider using premium fuel occasionally. The 1.4L turbo engine may benefit from the higher octane rating of premium fuel, potentially improving performance and fuel economy. Experiment to see if you notice a difference, but understand this may not be cost effective.
