We just returned from our Christmas Holiday trip to Nashville and back to Charleston, SC in our 2016 CX-9 GT AWD with 3000 miles on it. Its getting the same mileage as our 2013 GT FWD on the same trip. In the 1300 miles we drove, we got 22 mpg on 95% interstate driving. My wife gets about 18 - 19 mpg around town driving. Our 2013 CX-9 GT FWD got the exact same mileage. Our 2007 CX-9 GT FWD used to get 18 -19 mpg around town and 25 - 26 mpg on the highway. That car had the 3.5 ltr V6. I want that same engine back in the CX-9. I don't know why in the world they replaced it with the 3.7 ltr. V6 as performance is imperceptible but mileage was a lot worse. I think Mazda's Skyactive technology has gone too far with its weight loss. I've noticed the door panels flex more than the older CX-9. I traded in my daughter's CX-5 in for a VW Tiguan because it was built so flimsy. It was recalled for excessive hood flex and door mirrors that vibrated too much because of the lightweight steel in the door panels. It did not make me feel safe putting my daughter in that car. The plastic bumpers flexed so much the reflectors would fall off of them. (shrug)
