The new Defender has infinitely-variable, clutched differentials in the center and rear (on the rear if you purchase the electronic eDiff option). The differentials are not ON/OFF only (like the Eaton one -- and other old school differentials).
The clutched differentials are activated electronically, relying on sensors feeding the terrain response system (1 or 2). The best way to picture the differentials is to view that each has two variable clutches (Left and Right in the rear diff and Front and Rear in the center diff) to determine how much of the available torque each wheel receives. The driver has no direct input as to the use of the variable clutches.
The vehicle also has independent, variable, electronic, fast braking on each wheel to react very quickly to any minute change in available traction at each wheel; as well as electronic throttle control to moment by moment match the torque being created to what can be consumed by the four wheels without losing traction.
In Terrain Response 2, the driver can create different sensitivity profiles regarding the aggressiveness of the system for: steering sensitivity, auto throttle aggressiveness, fast braking aggressiveness and differential torque aggressiveness to match the system to their unique environment in which they are operating. Terrain Response 1 is not adjustable (nor does it need to be for most persons in most situations). TR2 is not something to master "out of the box".
Terrain Response 2 also has an AUTO mode, which does a good job for most drivers of setting an accurate set of aggressiveness settings based on the vehicle's sensor readings.
The result of all this is that the new Defender finds and uses minute amounts of available traction to a degree and in a manner unlike anything in earlier generations of 4WD. It took 20 years of steady development to achieve it.
There are trade offs involved -- the biggest being that the driver needs to learn how to drive the computer, instead of the vehicle directly. But it does work.
Enjoy !

I wanted to share a Brochure that was found discussing all the parts manufacturers. Some that stand out Brembo-Brakes; Tremec-Transfer case and EIBACH-coil springs and stabilizer bar.

Yesterday the digital brochure popped up with all the goodies for the new Grenadier. The configurator will go live on 5/19. warrenty 5year unlimted mile on Grenadier but you have to get it checked out every 12 months. Also, it has the ability to have a front and rear winchhttps://d28lcup14p4e72.cloudfront.net/268352/7666684/INEOS%20Grenadier_Digi%20Brochure_English%20UK_FIN AL_v2.pdf

Cool! I built a tray-mounted winch that plugs into the 2” receiver in the rear for my Jeep (and also have used it with the Defender.) I used a 4500# winch (I have 12,000# on the front of the Defender, 10,000# on the Jeep). It’s been very useful over the last 8 years. Sometimes going forward just gets you stuck deeper. So I’m glad the G-Wagon (as opposed to G-Wagen 
) has that option. They seem to really be thinking through all the problems people have hacking into new 4x4s to add lights and winches and rock sliders etc. (Yeah, I’m lookin at you, Land Rover.)

It looks wonderful and the brochure is so well put together! Only one thing looks out of place to me and that's the BMW gear shift....
Wonderful to see an idea come together like this. Can't wait to see one on the road

Or at least a match for the t-case shifter right next to it, instead of what looks like a Logitech mouse turned up on end. As soon as mine comes in Ima start looking for aftermarket retrofits.
