Lincoln using "AI" in AWD system?

Recommended Posts

I just saw this article from last year describing the new AWD system in the 2019 Edge, which disconnects/connects the rear wheels using artificial intelligence. Anyone know if this is what's in my 2017 MKX, or is it something new?

It was new for the 2019 models (new PTU hardware) so not applicable to 2017s.

The article makes it seem as though disconnecting the rear end was new for 2019.

I remember there was considerable debate about this on these forums when the announcement first came out. As I remember the conclusion, it is a new system and it does something new in how it shifts power around enabling the new system to provide better fuel efficiency without losing AWD when it's needed, but the older systems in the MKX also did this, but somewhat differently. It got a lot more technical than that, but I don't recall the details of the discussion.

Our '17 got its first snow test Sunday evening in Lancaster, PA and performed admirably. We had tickets to a show an hour from home, and went for it in the middle of the storm.

It is - new PTU and new software.

It’s is new but it’s been tested on some Jeep models. In normal (2wd)  mode it doesn’t even turn the drive shaft going aft. In the back the rear differential is disconnected as well. The rear wheels and shafts turn but nothing in the diff internals move (in 2wd). When prompted to use 4wd the rear diff engages, starts turning the drive shaft and at the same time the new style PTU engages and you have AWD.
