Default Torque Split & description of the MT/AT AWD system

Gidday All

Considering the amount of half-baked, misinformation about this in many threads, here is the link to the official Subaru/Fuji Heavy Industries web page that describes the torque split for both manual and automatic transmissions for all model Subies.

http://www.subaru-global.com/tec_awd.html

(Thanks to Thunder for the link to this link)

The standard default torque split for ALL our vehicles is either 50:50, 45:55 or 60:40 F:R dependent on the specific model.

NO Subaru vehicle has the much-touted 90:10 F:R torque split for early AT vehicles (I have been guilty of repeating this misinformation myself ... Sorry ).

I believe the ratios changed over the years where 60/40 was from 2008/2009. With a quick look I could find no reference to model year in the article.

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

Gidday Folks

This thread here contains the official Subaru info on the torque split:
http://www.offroadsubarus.com/showthread.php?t=4110

The official Subaru info is also at:
http://www.subaru-global.com/tec_awd.html

It appears that there has never been an AWD vehicle made by them that distributes torque 90:10 by default, or anything close to this figure.

I saw that thread. I'm surprised that the info about 90:10 distribution seems so consistent throughout all the forums I've read since it seems to not be true.

Like so many others I thought it was true too. Ahhh, dont ya love the inaccuracy of the interweb

My bros Honda CRV is 90:10 varying to 60:40 or 80:20, cant remember. I do remember him in fairly firm sand at Kalbarri spinning only the front wheels
