The 6 is already offered in AWD, just not in the US market. I don’t know if people are already aware of this, but recent 6 articles haven’t had any shout-out to this. If you check the JP Mazda site, you’ll see the offering, which I believe is the turbo diesel model. You’ll also notice it in Gran Turismo Sport.

I also this it is super important to note that, on their website, I configured a 2.2 turbo diesel MT 4WD wagon model successfully.

So, it exists.
