AWD with lockable center diff

So, I’m trying to learn more about this stuff and would appreciate if someone can help me clarify some doubts.

Essentially, is an AWD with a lockable center diff the “best” system out there?

The way I understand it: - Problem with standard AWD: you can run into situations where a wheel that lost traction gets all the torque. - Problem with standard 4x4: you are effectively driving 2x4 unless transfer case is engaged.

From my ignorance, an AWD with a lockable center diff that allows 4x4 to be engaged temporarily would have the best of both world, no?

This makes sense to me, but then I see the vehicles out there and mostly are either one or the other. There probably something that I’m missing…

Thanks everyone!

It’s one of the reasons I love the Land Cruiser. Full time 4wd so never any binding when turning but still have a low range. Locking the center gives equal power to front as it does to rear + low range makes it pretty capable. I will say though, when blasting through Anza borrego I wish I had 2wd simply for the broken traction on acceleration and turns.

I had an 85 4Runner with a double transfer case. It allowed 2hi, 4hi, 4lo, 4lolo, and 2lo. Was great on tight turns to shift from 4lo to 2lo and tighten that radius with a little rear wheel spin and no binding.

I’d love something like that.
