Doing some research into how the 4wd system works in the next-gen Rangers with the permanent all wheel drive transmission I came across this article on Blue Oval Trucks that does a good job of explaining things.

So looks like the answer is that the transmission uses a centre clutch which is able to vary the lock-up when in 4A and likely locks totally when in 4H/4L. The Land Rover New Defender (from MY2021 onwards) seems to use a similar system - discarding the centre diff and replacing with the clutch.

G'day Peter,

Yes this is how the AWD works, the front axle can be engaged either by a multi disc clutch having pressure applied to it, or through a traditional dog clutch (this is 4H and 4L). The previous Everest used this too, without the dog clutch.

Thanks Bill, really appreciate that.

I don't know why I couldn't find that video when I was looking for the information.

I think It would be really great if we could use low-range with the clutch and then only engage the dog when absolutely needed. This is the type of behaviour we get on modern Land Rovers and it works a treat when up in the high country where you want low range but many of the roads are quite hard-packed so you prefer to not have the front and rear tightly locked together.

I totally agree, low range AWD would be perfect. The G-Wagon also allows this, and it's fantastic.
