"The Toyota Land Cruiser/Lexus GX-LX, Land Rover LR4/Range Rovers, Jeep Grand Cherokee with QuadraDrive/QuadraTrac (and others too) all have permanent 4WD (or AWD if you prefer). All wheels are driven all the time, and there is no 2WD mode available."
Those are all AWD, not 4WD.
I think you are defining AWD as permanent 4WD.

All four wheels are permanently engaged all the time, they all have a low range gear in the transfer box, and are all excellent in off-road situations. Sounds like 4WD to me, but call it what you want.
You can also include the Mercedes G-wagon in that group as well; all premier off-roaders with permanent 4WD (or AWD if you prefer).
Again, I say this AWD/4WD debate is all about marketing. They're all four-wheel drive vehicles. It just depends on how the brand wants to present itself; AWD or 4WD. The RAV4, Highlander, Pilot, CRV and Grand Cherokee (maybe others too?) all have clutch pack center difs, yet those brands specifically call their systems "4WD." Other models with similar clutch-pack units market their drive system as AWD.
Now some differ in that they're reactive "on-demand" units, engaging either the front or rear axles only when tire slippage occurs (none of the ones I mentioned are that way); while others are proactive "permanent" units, in which some power is always sent to both the front and rear axles.
