I track my mileage religiously using Fuelly and so far my AWD sedan is getting 24.2 AVG MPG in the City. The BEST MPG that I’ve gotten so far is 27.9 on a short HWY trip from Orlando to Daytona Beach and back. Granted I only have 1700 miles on the car and it is SLOWLY climbing as the car breaks-in but so far the fuel economy is one of my biggest disappointments. I’m looking forward to taking a road trip soon to see what I can get on the open road. Really hoping for 35 or better with cruise set to 75. I have to wonder if a 2.0 Turbo would return better fuel economy than the 2.5 L with Cylinder Deactivation. So many other car manufacturers are getting better results with a 2.0T that there must be something to that. I am really looking forward to the new Skyactiv X. Mazda should have brought that engine to the USA first and not given us the lame “Fuel is Cheap” excuse. The USA is one of the largest car markets in the world yet we get cars that are stripped and devoid of features that are present in other markets. It doesn’t make sense that we pay the same money and get less.

It took a long time till I was seeing an average of over 30mpg consistently. Finally at 200k I'm getting around 34mpg. But I typically do my commute 73mph one way that's slightly up hill and 75mph the other way slightly downhill. I also have to drive like a granny all the time, I'm normally in the busier freeways doing 65-70. A 2.0l turbo isn't going to do better driving around everywhere with your foot in it. That's just the nature of the beast. If you get used to driving without the rpms exceeding 2500rpms you'll do better.

As they say, mileage will vary, but........
I have a 2016 Mazda 6 2.5L with 50K miles. Specs say 38 HWY. On a recent trip I got 36 MPG with the cruise control set at 80MPH. Big contributor was that this was with Arizona gas. I have never gotten above 32 MPG using California gas, even driving slower on the highway.

Boy I am sure glad I am paying that extra dollar a gallon to get 15% lower mileage because of the special boutique gas the big California refineries and ex-Governor Grey Davis came up with.

Idiot.

If you are in California, you should factor in at least a few miles per gallon into your disappointment due to the gas.

Airizona is typically higher altitude where the air is a little thinner. Anywhere you get higher altitude you will get better mileage. It's been my experience across the states.
