I used to think that Subaru used only one basic AWD system that
delivered 90% front and 10% rear power under normal condidtions. Those
specs are out of the owner's manual for my wife's '97 OB Sport 2.2l.
There is no mention in the manual of my '00 OBW-LTD but I assume it's
the same. (Both vehicles have automatics)

I'm trying to figure out the "Symmetric AWD" advertising. Doesn't this
somewhat imply a 50/50 front/rear power split? Is this a newer system?
I've also thought I've seen something about WRX and STI models having
more than one system.

I'm not jealous of something different, it's just that old nagging
curiosity.

The 90/10 system has done exceedingly well on my wife's car. I've only
driven it twice in conditions where it was heavily needed and was very
impressed. She3's been thru some wild stuff.

I only recently purchased my OBW and am waiting for "interesting"
conditions to evaluate it. (the hell with that.. I wanna go play in the
snow!)This will be my first vehicle in 40 years of driving with a
limited slip diff in the rear.. add AWD and it's gonna be fun !

Current systems are Liquid Viscuous Center Diffs and are 50/50 split. The
system for the automatic is different than the system on the standard.

The STI system is different. It is mechanical and biased slightly to the
rear. There is also a DCCD contol that allows the lock-up of the center diff
to be manually controlled.

under Why Subaru, select Symmetrical AWD. There are 5 systems (though
really, 3 basic systems as said in the other post) The wet clutch-pack
in the auto, the DCCD Torsen in the STI, and the Viscous Locking like in
my WRX. The Symetrical refers to the layout of the drivetrain to set it
apart from transverse transaxles I guess.
