So then could I assume the diff locks are variable so that you don't end up with the rear end swinging around on you when you're on ice? In other words, does the computer apply enough diff lock to keep traction but not so much that you lose control/stability? If that's how the software works (Terrain Response tied into the DSC) then that's quite a technical advantage over an manual system where you only have two choices - lock or unlock. I can see why they don't call it a limited-slip rear diff lock now, because "limited" implies a "limitation", when in reality the variability is it's advantage. Interesting.

Thats it exactly, the amount of slip or lock is continuously variable, dependent upon the amount of pre-load applied by each TR mode and feedback from wheel speed sensors. In extreme circumstances, the temperature sensors within the differentials will limit the amount of activity to preserve the friction surfaces, in this case TC will take over to maintain forward progress - although you'd have to be on a prolonged drive acoss difficult surfaces at extremely high ambient temperatures for this to be invoked

I guess I should have just looked at the Land Rover website under the tech specs section:
Quote:Two-speed electronic transfer gearbox, shift-on-the-move capability, electronically controlled infinitely variable locking center differential, optional electronically controlled infinitely variable locking rear differential
Would it be safe to connect-the-dots and assume that it's highly unlikely you will ever break a CV while off road in a D3?

Highly unlikely - although the risk is increased in 'extended +' height... just basic physics really 
With a bit of luck, if it ever happens there'll be a friendly RRS nearby to drag you to safety
