I still don't think anyone here knows what "G-Vectoring" is, or at least, how to express it.
In the other thread...
"Mazda finally has an engine responsive enough to do this with"
and
"It doesn't have anything to do with torque"
and in the flier/publications
"reduce and derive optimal torque"
So...from all I've gathered, it's basically GM's PTM except in "daily driver mode".
If that's the case, that's pretty cool. It's nice to see trickle-down technology from the race track and sports cars into daily drivers like the CX-5, that makes a difference. It is, however, a decade old nearly (ZR1 was the first vehicle I am aware of that debut'ed it to the masses, if you can call $100K+ "masses".)
Basically, from what I understand, it will over-ride your driver input from your right foot, based on a myriad of other things. It does not increase absolute limits, but rather takes the human element somewhat out of approaching them, as regards the accelerator.
What confuses me is how it took mazda this long to come up with a 4-banger that responded decent enough when GM did it almost 10 years ago with a 6+ liter supercharged V8 with a lot more internal rotational inertia.
Basically...cool. I think it's great. I think Mazda is closet-shamed about how long it took them to do what GM did/what it really is (which is why all the conflicting info due to their convoluted "explanations" trying to make it sound more grandiose than it really is).
That said, really no shame honestly, as Ferrari, Ford, and others go to GM when they want a suspension. Mazda can admit it. It's ok
Seriously though, it's a great tool in the tool box, and a true safety feature (in this application) that should bail people out in the snow. I'd like it for the snow/rain for sure!
Long story short?
Mazda's G-vectoring reduces throttle input, or increases it, minutely, to compensate for changes in traction before the driver can feel them, based on vehicle dynamics and steering position and wheel-slip sensors.
Traction-control Plus.
