I was searching through 500X inventory at several Northeastern studios, and noted that the 2017 500X AWD is now rated at 21 City 29 Highway, so it's kind of a wash. MPG in city driving is up one, while MPG for highway driving is down one, when compared to the 2016 ratings. I understand that the EPA has a different fuel economy test starting MY 2017 that is supposed to better reflect "real world" driving conditions. It seems to me that Fiat have been fairly conservative in their FE ratings, though so far it would appear that the 500X ratings are fairly close what people are reporting.

Didn't see any FWD 500X's in my search, but I imagine it'll be something like 21/30.

Correction: 2016 500X AWD EPA figures are 21/30, FWD is 22/31. It's worth mentioning that the 500X tune hasn't changed from 2016 to 2017, so the EPA fuel economy figures just reflect different testing methodology.

In the case of the Fiat 500X, it does seem that the fuel economy estimates are fairly close to the figures reported by most owners, although many of those owner reports are based on the initial months following purchase, often before the first oil change, which is often lower than the potential after allowing the engine and drivetrain to fully settle in. I wonder if the manufacturer's estimates take this into account, knowing that many owners pay close attention to things like fuel economy during that timeframe. Most vehicles achieve better fuel economy after more substantial time and use, and the Fiat 500X doesn't disappoint, I have ~27k miles on my 2016 Trekking AWD with 2.4L and 9-speed, and the fuel economy keeps getting better, my last highway trip averaged 35.8 MPG according to the onboard trip computer, or 35.3 MPG according to 265 miles driven / 7.5 gallons of fuel to fill up the tank. I reset Trip A with each fill-up, and pay attention to the fuel economy, even when I drive a full tank in-town with stop-and-go driving, the worst average I'm seeing these days is about 25 MPG.

I too have the 2016 Trekking AWD with 2.4L and 9-speed and at 6000 miles I'm lucky if I hit 23mpg per tank (usually its 21-22mpg). My daily commute is 12 miles each way, either 1/2 highway and 1/2 40mph roads with 3 hills and 5 stoplights, or 12 miles all at 30-45mph of twisty backroads with only 3 stop signs.

I keep hoping it will still improve over time.
