New to the forum. Just wanted to share my MPG results (giving back to the community from which I have learned alot). Have the 2018 GT AWD (2.5 NA engine of course) bought in June 2018, and have about 6500 miles on it. The car is mostly used for very short city trips during the week (work, gym, etc), and occasional long distance roadtrips on weekends.
Our city mileage is pretty crap, around 21-23 mpg, though this is not unexpected for our driving conditions (very short trips). Highway mpg on the other hand is excellent. I consistently get the expected ~30 mpg (little over or little under), and at times even a few more, i.e 31-33 mpg. What I really wanted to show others, is that on one commute (sometime in September, at night) I got 35.0 mpg. VERY NICE. It put a big smile on my face. It was about a 50 mi drive, all freeway, light-to-no traffic, generally sea level but some low mountain passes (Bay area, CA), and consistently 70-75 mph (and while overtaking up to 80 mph). I will attach a pic of it, if admin allows a fresh user to post pics.
If we had a true mix of city/hwy for our weekly commute, I am sure our overall mpg would be looking good. All the same, mpg wasn*t my highest priority when buying this car, so still overall quite happy with the purchase (trouble free and very nice car overall).
