How does an AWD get stuck like this with one wheel spinning?

Broken transfer case and differential… The typical power output is to all four wheels, with 41/59% torque distribution being most common… But if things aren’t working correctly, it only takes a small bump to get the car stuck as shown; the driveshafts which are not spinning are not receiving any power…

Noteworthy is Toyota Rav-4’s and Honda CR-V’s electronic differentials which sometimes only engage partially at the rear, because the engineers “didn’t expect the rear differential to be used.”

Basically, they only made the rear differential strong enough to survive ~90 HP at the rear wheels… So, if the front wheels spin, the TCS will disable the front wheels and send ~90 hp to the rear wheels… But, it’s a heavy SUV; guess who suddenly doesn’t have the power to get up the hill?

Then, in the same test, it was proven impossible to stop the Forester (Subaru) from arriving at the top…

All-wheel-drive is the only way to go, and it must function correctly. If you’re the one who gets an AWD car stuck, you’re the most embarrassed…

Non-locking diffs maybe ?
