you have to get out and engage the locking hubs....simple
this gives you the opportunity to inspect the terrain that the all round cameras and sensors have already assessed.
So the Land Rover specs contain the following small print:
"1 Permanent All-Wheel Drive is standard on Land Rover Defender except for those fitted with new D200, D250 and D300 6-cylinder Diesel engines"
Can anyone here explain what that means and why it applies only to the diesel-engined variety?
Land Rover doesn't give any explanation as far as I can tell.

The D MHEV programmes can determine and disconnect the front wheels from the drive train if not required as far as i can remember,
uses some clutch pack, idea is to save you a minuscule amount of Diesel when on tarmac..and no doubt ensures Gerry Mc can
state he has green credentials

"Intelligent all wheel drive" is the phrase
More complications with very little up side.

Yep. This is one of the reasons why when I suddenly found myself with the opportunity to change vehicles late last year I bought a 20MY vehicle in the wrong colour and with an unwanted sunroof from dealer stock rather than ordering a new build. The new driveline on the 6-cyl diesels is apparently a tiny smidge more fuel efficient but really seems like a step backwards in terms of driving four wheels with optimum traction.
Where the electronic centre diff has for a couple decades given us permanent AWD with automatic centre diff locking as needed, the new system is basically an automatic clutch version of the old 2H/4H and locking hubs arrangement. The only reason for doing it is to reduce spinning mass and friction losses in situations where RWD will suffice. Doesn't seem right for a Defender, especially a diesel one.
Ok does that mean all current model
Defender diesels are now intelligent (part time) FWD, and only the petrols non hybrid are full time FWD?

Ex 300Tdi Disco:
Depends what you mean by "FWD".
If your "F" means "Front", then no. The transfer case doesn't have a differential component any more, and the rear drive shaft is a permanent connection from the TC to the rear diff. The rear wheels are always driven. The centre clutch controls whether any drive is also given to the front, but remember there's no diff so it's a 1:1 ratio just like old-school 4WD mechanisms.
If your "F" means "Four" then yes.
I think what we are witnessing are the dying throws of the diesel engine given the emission control regulations being introduced particularly in Europe. Canada and the USA don't import the diesel-engined versions.
These are marginal gains from major engineering efforts. We are working beyond the Pareto principle.
