From Forester Technical Description Page 19 for the second generation Forester “Automatic Transmission AWD” Subaru Australia publication P-FTB03:

“This system can infinitely vary the distribution between 95% front and 5% rear wheel drive to a 60/40 ratio with static weight distribution”

It's a PDF so I'm happy to email it to anyone who is interested - PM me your email address. I have also updated the referenced thread on the subject with this correct information.

As I've said before, the ratio has changed over the years.

Gidday Kevin

I would like a copy, thanks.

However, note that again they state what is on their web site that the default is "... a 60/40 ratio with static weight distribution."

All the other stuff is saying is that the centre diff can vary the torque distribution a lot, depending on the circumstances (which we all knew). It appears that this has been taken by some to mean that the default is one of these other figures.

I was also reading up on the DCCD here, which is different again (like Lego, LOL!):

No, it does not state the default is 60/40 at all. The current technical information on their website woud not apply to 11+ yo vehicles.

There are different computer maps for the AWD in the 4eat depending upon throttle position and gear selected. WOT and 1st is almost a 50/50 (or 60/40 depending upon year). 2nd and third are more aggressive in the awd split then D. That was all on a endwrench article I can try to dig up if someone wants to see it.

Thanks, nipper. Very interesting. Makes sense that staying in 1st would give the most even torque split between front and rear.

I would definitely be interested in that article! Sounds like they researched the article in quite some detail. Having their data would help not having to reinvent the wheel here on ORS.

I saw all the endwrench articles posted on that other thread. I read through I few of them and I didn't find that about the awd in 1, 2, 3 or D. Do you know which one it is, I'd like to take a look at it.

I have to research it, give me a few days, as it may very well be on my computer and not the net

Question

Ok, I have a 4EAT with a HOLD and POWER switch.
Now I know the HOLD seems to give me 50:50 torque split as well as blocking off 1st gear. Meaning it starts in 2nd and remaps the AT gear changes to much earlier revs to prevent wheel spin on mud/ice during a gear change.
But how much does the POWER option affect the AT torque split?
As far as I have read here nothing has yet covered these extra AT options.
