Hello, new N Line owner for about 2 months. Just curious if other are finding actual gas mileage much higher then advertised. We have driven about 2,000 KM and overall fuel economy shows cumulative average of 6.8 l/100K, or about US 34.5 mpg. About 80% city driving and 20% hwy driving , fwd driven in smart mode by my wife, very pleasantly surprised at fuel economy.

Also, I wonder if the remaining gas mileage until empty is accurate as my wife filled up and there was about 100km remaining but when filling the tank the pump clicked off after filling up just under 40 liters when the tank is supposed to hold 50 liters?

Yes it is underrated in my N model I have seen 35.4 to 35.6 mpg in eco mode driving up from Tucson to Phoenix.

I have a full N, so what I see fuel economy wise isn’t directly applicable to your experience…but I will say that my car routinely beats its EPA highway estimates by 4-5 MPG or so. I’ve even seen as high as 33 or 34.

The FWD Turbo GDI engines can have great mileage. AWD is just heavier and more friction-- so lower mileage.

Mine is now saying 35.6 overall for a 20 Limited 1.6 Turbo GDI DCT.

Now...I drive a lot of back roads and Highways. If I drive about 50-60mph, the computer says something like 46mpg.

I think it all boils down to your environment. City/Urban traffic can kill the mileage.

Just me...if you drive a lot of stop and go driving, take it out on the highway at least twice a month. You may have less problems if you take it out and let it run at 70=/- mph for 20-30 mins every other week.

My 34 mpg were most urban driving, hwy driving at 55mph saw mpg in the 40 - 42 range, I was just wondering if the calibration was off or if mpg estimates are on the low side?
Drive a few tanks before drawing any conclusion. There is a reason 55 used to be the speed limit and you might have a tail wind that day.

The N line is AWD on Canadian models.

We got 39 on a 350 mile trip at 65. Seems like it is getting really good milage if driven easy. 1600 miles on fwd N line.
22.5 to 23 around town with sport mode.

Most manufactures test their city driving at 25 MPH with stop and go traffic and highway at 65 MPH without really any traffic. Most cars are most efficient at 55 MPH.

My Elantra Sport with the 1.6t and DCT averaged 39 MPG at 55 MPH traveling speed and around 26 MPG with city driving averaging speed of 27-30 MPH, and around 22 mpg with average driving speed of 19 MPH. I did get some higher MPG on that car with the highest being 42MPG.

My Kona N using those same metric I get 34-36 mpg on the highway with speeds at 55 MPH, 23 mpg with city driving speed around 30 MPH and 19 MPG when my driving speed is around 19 MPH.

As you increase speed above 55 MPH your gas mileage will slowly decrease. Both my Elantra and Kona have lower MPG at speeds above 55 MPH. Kona N averages around 30-32 MPG at 70-75 MPH and the Elantra MPG dropped to 34-36 at speeds of 70-75.

As someone else stated, there is a reason that highways speeds at one point were set to 55 MPH, it was for fuel efficiency.

Yeah, for these kinds of cross-over SUVs, if you want to call them, the drag co-efficient isn't exactly impressive. This results in quite a bit of parasitic drag as you go ever above 55 MPH.
