Exterior-wise, I like almost everything. Rear looks especially good, minus the decision to replace the Mazda emblem. I really like the lower trim treatment on the doors, nice little callback to the original Kodo design of the 1st gen CX-5. I don't like the little "tabs" on the top of the fender trim pieces, or the "underbite" of the lower half of the front bumper - it looks too bulky, especially at 3/4 angles.
Interior, again, I like almost everything. I wish the seats had a bit more detail, but they will likely change that up a couple of years in. Dashboard/screen placement looks really boring, almost like a Tesla interior (but maybe that's what they're going for). Screen size looks nice and big, but I can see that being a big distraction to drivers, especially if the HVAC and radio controls are nested in submenus. It's a complete departure from when they put the infotainment display further away from the driver in the Mazda3 and took away touchscreen capability in an effort to make shifting focus from the road to the screen easier and eliminate distractions. They also took away the control knob, forcing you to have to touch the screen to do anything, inviting even more opportunities for distraction. They should have at least left the control knob intact.
If I were in the market, I'd probably wait a few years for Mazda to iron out any issues with the touchscreen software and hardware. That screen needs to be reliable and lightning-fast.
