I'll stick to my NA Mazda too, speaking of NA Mazdas got some official 17 specs (not printed sitting in front of me) but definitely official from my dealer's computer..however they're from my recollection so I may be off a tick or 2 here or there...notable highlights:
187/185
23/29 AWD 24(I think)/31 FWD
365X..AWD curb
65.3 height w/o rails, 179.1 L
30,655 MSRP before dest for AWD GT (sorry I missed others)
LEDs standard on touring and leatherette with faux swede inserts
GT includes most/all of i-active stuff I believe
same tire/wheel sizes for all 3 trims
Sorry I'm sure this doesn't answer everything but so far I've seen nothing so yeah idk she definitely put on lbs..maybe for good but seems like the 16.5 may have gotten a tad more compelling (on paper obviously) for me...although I like the lower roofline which at 2" is more significant than expected..should fair better in wind. I wanted to look at gearing but a) I wouldn't have remembered and b) I had to run
