I took the MZ5 to the Mazda dealer to look at a Skyactive CX-5. I drove an AWD auto and can say I didn't like it at all. The powertrain, that is, the rest was great. I understand the setup if MPGs are your number one priority, but I can safely say if the MZ5 had that powertrain in it when my wife test drove the MZ5, one would not be in our garage currently.
Way too much NVH on startup, and the lack of power (low-end torque) is not fun at all. Our MZ5 runs around with anywhere between 3-6 people in it frequently. The 2.5 feels peppy when solo and adequate when loaded up. No way the Skyactive 2.0/6AT would be happy at all.
I wish Mazda would bring on the diesels already installed in the MZ5 elsewhere.
