Without going too far down a rabbit hole, I have to say I am extremely impressed with the traction control / Terrain Response system in the Defender. For a few weeks a year, I help as an instructor/guide for Land Rover events and spent over a month recently in the 90, 110, and 130 on and off road at the Trek, Trophy, and Destination events. I was amazed with the limited articulation how capable the vehicle is - even on stock, pavement focused Goodyear tires.
At Destination Defender, the challenging course was a complete mud fest from 3 days of non stop rain, but the Terrain Response 2 (we also had the auto rear locking diff on the Trophy vehicles) made it possible, if not easy, for people with little experience to go through the course. What surprised me the most about the system was how seamless and quickly it responded with no noise - a welcome change from the chatter of the Toyota systems I'm used to. Lifting a wheel shows how well balanced the vehicle is, and the 4 wheel independent air suspension reminded me of the Rivian in some ways. The Rivian has more adjustability and clearance, but it also weighs ~1,500 pounds more which you can feel going down steep slippery stuff or when you lift a tire high off the ground.
As you can see here, the ground was extremely muddy and soft, but even with stock street biased tires and a wheel off the ground, it just finds traction and moves right through!
