I'm new to Mazdas myself so not sure if there is another official term for cylinder deactivation, but I couldn't find anything about it in the owner's manual. I did find this for i-stop though:Was at the dealer this morning for some routine maint. on my 19 Reserve. Dealer had a decent amount of 26's. Had the salesman open one on the lot so I could sit in it and play around with the controls. Still has CD. Not sure about I-Stop. The off button was not on the left of the steering wheel like previous years, it may be buried in one of the menu screens.
The missing controls weren't as bad as I thought they'd be. The screen is big enough and the important buttons for climate control are across the bottom of the screen. Kinda like having a row of buttons but touch sensitive icons instead. Infotainment seemed pretty responsive. Will take some getting used to.
Dealer also had some 25 Signatures that were really nice and in the color that I'd like.
Hard decision - get a 25 now or wait till 27 for the hybrid. Probably will wait.
