AWD godmode fail

It rained and Pandasaurus isn't used to driving in slippery stuff.

Rescue #2 for the Tacoma. 😛
 
After thinking about it for a couple days, I figured out what happened.

Passenger front wheel was conveniently (or stupidly, take your pick) parked right on top of a previously-filled hole that was dug in the yard for plumbing work. Rain = Return of The Hole: Episode II.

I also <3 bugeye wagons. Even when it's stuck in the mud in my own front yard. 😀
 
Did you try to back it out? I've seen Subaru's manage worse than that.... granted with snow or all terrain tires.

Dunno about that. It looks like he bottomed out when he got into that soft spot. Actually, he probably coulda cleared it if he was going faster. Putting gravel behind the front wheels may have given enough traction to pull out of it, but not necessary if you have a friendly trucker near by.

I assumed it was parked there and they were backing out.
 
If he lifted a wheel off the ground, he wasn't going anywhere regardless of the terrain. Subaru AWD works great until a wheel lifts, then the car is basically disabled until you can get it on the ground again. :/

All four wheels were on the ground.

I'm sure I've seen several videos showing that Subies need only 1 wheel to have grip to move.

I'm not sure how the auto transmission setups work, but my Forester had a fixed 50/50 front/rear split and I believe a rear limited slip diff. Maybe if there was a wheel off the ground up front and another wheel off the ground in the back, you'd spin..but chances of that happening anywhere you're driving a Subaru is unlikely.

I believe most subie auto's use a viscous coupling that adjust grip between front/rear.

But depending on the trim, the diff's might be open
 
Their demo video has 3 wheels on rollers, so they have no grip at all, and one wheel on the ground, and they are able to drive off the rollers.

Having one wheel on a roller, with no grip, should not be a problem.

Anyway, here's Jeep's Quadra-Drive 2. 😀

The picture of the car looks like a stock imperza 2.5, wont make a difference if its automatic or stick. It also has open diff's. IE one wheel on an axle slips, that axle has no power.

most cars are like this. any 2wd car is really 1wd, and any 4wd is really 2wd corner to corner. positraction can help, if its working well... but it also gives you less traction on cornering...

No, both wheels in a 2WD system with an open differential get power, not just one. Just the max that can be applied is equal to the least amount required to spin one wheel. So if one wheel spins (on ice for example), the other wheel only gets the same amount, which isn't enough to move the vehicle so it doesn't go anywhere. Same idea with 4WD on a per-axle basis if both front and rear have open differentials.
