Interesting...
    
The Forester is supposedly FWD biased even though it's an AWD car. Yet when accelerating on snow and ice, the '09 swings its tail out rather than understeer severely (as my former FWD cars would do on bad roads).
 
Perhaps for '09, Subaru changed the balance of the AWD system to be more rear end biased?

It might just be that the rear end is lighter (44% vs 56% up front). My old Pathfinder used to slide around in 2WD. 300lbs of sand in the back took care of it.

Do you have the 4AT? My understanding is that the VDC will send more power to the rear on acceleration -- and more to the front (engine braking) on deceleration.

From what i've been reading, for automatic foresters, the AWD system sends 90% of the power to the front and 10% to the rear in D in normal conditions. Switch it down to manual mode in gears 1 and 2 and you'll have 50/50 front and rear. For manual transmissions you get 50/50 in all gears. Once the AWD system detects slipping it will send more power to the wheels that have traction.
 
I've bought a set of dedicated wheels and winter tires for my 09' Forester 2.5X Premium. I ordered them from tirerack.com. I got 16" alloy wheels with 215/65-16 General Altimax Artic tires. I wasn't even going to bother with the oem Geolanders during the winter months. My previous SUV with its all-seasons was a nightmare in the winter. If it wasn't in 4wd it wasn't moving! If you want maximum traction in winter weather, a dedicated winter tire is the only way to go.
 
This was my first set of winter tires and so far they have been great, i've gone through heavy rain in 40°F weather to wet roads at freezing temps and the forester drove like the pavement was dry. I tried taking some quick turns and fast take offs on wet pavement, but i haven't been able to break them loose. I still haven't tried them out in the snow, but were going to get a good amount of snowfall here in New England on Friday, so i'll get to test them out!

The '09 XT only comes with an automatic (4 speed).
Perhaps the '10 will re-introduce the 5 speed manual (it was dropped after '08).

yup, only the 2.5X comes in a manual. It would be nice to see a 5 or even a 6 speed manual in the XT. A faster shifting 5 speed auto wouldn't be much to ask for either!

I would agree. I've got an 04 XT manual, Love it! I couldn't believe Subaru dropped the manual.

Have you driven many other AWD vehicles in similar situations? It is actually a common trait and something I use as part of my test drives. I get on gravel or snow and turn the wheel then hit the gas. The on-demand AWD from FWD default like the Toyota or Honda will slip the front wheels and then power up the rear which feels like a kick in the pants and can snap the back end around too. The Subie version feels more smooth in the power transition, but gas will still spin out the tail as it will for on any vehicle putting power to the rear wheels. You have to be more gentle with the throttle than you would with a FWD vehicle; full time AWD vehicles need to be driven differently. Get into a parking lot and play with it - often. After a while you'll see what makes the car oversteer and what can make it understeer and how to correct both simply by turning the wheel and varying the throttle.
Now I found the Subie VDC to be the least intrusive, but that also means the least active. I feel very comfortable with the level of traction and stability control it offers. I hated the Toyo at the other end of the spectrum it still slid, but the VDC set off an annoying audible alarm and you could feel power being cut and coming back on and there was even kickback at the wheel. What I disliked about that was the fact I couldn't tell what it was doing to make my own adjustments and actually felt like I was fighting the vehicle. That being said, the Toyo was the hardest to slide. I've been driving RWD, 4WD and AWD vehicles without VDC for over 25 winters so I much prefer the Subie, but for my Nanny driving the kids in icy conditions, I'd prefer the Toyota. I'd put the Honda in between the other two.
For most situations, I'll bet that folks coming from FWD vehicles just need to be more gentle with the throttle. The FWD doesn't punish too much acceleration, but AWD vehicles will. With all 4 wheels gripping, you can be more conservative with the throttle and still get moving. Just wait until most of the turn is completed before getting on the gas heavily.

'09 XT snow report by redherring1

Finally had a chance to drive the '09 XT Ltd. in significant snow--got 5" the other day in Chicago with about 8 more to come today. Gotta tell you, this thing is magic in the snow--pulls like a tractor. I actually liked it better before they plowed, because once they did more of the underlying ice was exposed and then it didn't do as well. I noticed the 4 wheel drift tendency when accelerating through a corner also, but it's very predictable and therefore controllable, unlike my old CRV--in that, which was front wheel drive only until slippage was detected, usually the rear wheels would engage halfway through a corner which had the tendency to push you straight ahead. You could anticipate it somewhat, but since slippage is erratic it was much harder to control than the Forester. My daughter banged it into a curb and bent the front suspension as a result of this.
 
I haven't notice the wheel well buildup like some others have, but it was only about 15 degrees when the snow fell which makes it a lot less sticky.

Can anyone confirm this, or point me toward a reference -- I find it interesting.
 
Thanks,
