Cool video, thanks for sharing. I assume the new Defender wasn't fitted with a locking rear differential? Rear lockers, even the electronically controlled ones of modern Land Rovers, would probably make a positive difference in a couple of those instances where TC appears to take some time and quite a bit of rear tire spinning aimlessly up in the air before figuring it out... But yeah, the trick with this TC system is to keep a slow and steady input and let the car figure it out, which it usually does. I look forward to testing the configurable TR system, to see how much difference it makes in the real world. For that trail, I would have probably locked both center and rear diff, and allowed more wheel spin to minimize the nanny effect of TR/TC. 20" ATs would not have fared much better (as long as we are talking stock sized ATs), since the overall diameter is the same as the stock 18s or 19s, so no ground clearance gained... As a matter of fact they may have done worse, as people usually don't air down lower profile tires (such as the stock 20s) very much, too risky. |

If the South African new Defenders are similar to the Australian and New Zealand market deliveries, Goodyear AT Adventures are the standard tyres supplied from the factory, All season are an option in the ANZ market, could be the same in SA Cheers yet another pommie bar steward down under MY20 110 P400 SE Defender MY10 3.0 RR Sport |

No idea, but I’ve been told to expect a build date of October. |

Yes, it comes standard in ZA with the Goodyear AT or you can option the Duratracs. My mate just prefers BFGs. Also, what was interesting to note is that the ZA spec doesn't have AdBlue, which is great for us when touring in Africa  --

likely to go Duratracs, although there is a lower speed rating than the AT's the regulations
in Australia seem to suggest on 4x4's you can put a lower specified off road tyre on as long as it is not rated to less than 140KPH  My prospective insurance company said they were
fine as long as i am was not speeding or exceeding the tyres speed rating (which is 160KPH) yet another pommie bar steward down under MY20 110 P400 SE Defender MY10 3.0 RR Sport |

Naks that was an awesome video, great to see all the different landies together .. thanks for posting
edited: to add, it seems with the e-diff, there is less wheel slip from what i observed in many of the other videos that are out there.. The vehicle seemed far more composed in a number of cases rather than purely scrabbling.. yet another pommie bar steward down under

not sure if this has been posted here, but the brake failure at the 50min mark is scary!!!

I lost it with the d5 on a very steep iced up road we were waiting for the stuck cars in front. foot firm on the brake, we could hear creaking then it just started going backwards serious brown trouser time my brother said he could see immediately the wheels rotating and stopping repeatedly trying to get some grab. Wonder if this was similar or indeed a fault. 110 MY23.5 X Dynamic HSE

I saw exactly the same thing with a Disco3 on Sunday, wheels spinning in forwards motion but the car sliding backwards and sideways uncontrolled. The general conclusion was that the mud the driver had just driven through in his AT shod car had completely clogged the treads and the wet mud then wet grass he was trying to drive on was like driving on ice, no grip and the mud in threads not getting cleared out. Fortunately no damage or injuries in either case but in both cases rather scared drivers. Those of us with MT shod wheels didn’t have as much clogging of the treads and were able to get clear enough with some difficulty that we could rig up enough cars with winches and to act as ground anchors to recovery a D2, G4 Defender 110, another 110 and the D3 from the location that they were not ever going to get out of without help that wet afternoon.

If the vehicle is sliding down a hill it is possible (or even likely) that the wheel which is spinning forwards is actually being driven forwards by the wheel at the opposite end of the axle rotating backwards by virtue of having some grip.
I have had a similar effect in my 80" in snow on an steep descent, when I realised that I was travelling faster than the engine speed should have allowed. It wasn't a panic moment (single track lane between snowbanks, so plenty of opportunity to stop by heading for a snowbank) so I stuck my head out of the window to see what was happening. The front wheen was rotating at road speed, the back wheel was rotating backwards. On the other side I presume that the front was rotating backwards and the rear forwards. An inevitable situation under certain conditions of loss of grip. I have no idea how a modern TC system copes with this situation, since it must be quite difficult to reconcile the conflicting inputs. I would like to think that the hoof on the brake pedal would be a strong clue, but if the system concludes that the wheels are locking up on a vehicle that is supposed to be moving it could be problematic. Just one reason why I am happier without ABS and without TC. At least the vehicle does exactly what I tell it to. |

Wasn't the sub £50k one at a main dealers in uk a base spec? |

My dealer has a base spec sitting in their compound, in fact I think it’s their 3rd, I had a look around it, it has everything most people need and more.

When mine was doing it my foot was firm on the brake but it was clear from observers some wheels were receiving intermittent forward drive. So I wonder if this is Electronic trickery trying to fight physics on behalf of the driver. The car knows with the brake being pressed the intention is to slow or stop but senses the slide and the fact traction is lost so invokes drive to try and counter the physics at play as best it can. To most drivers I guess this is the best endeavour but would be nice to be told what’s happening or turn it off for those who feel more comfortable with their skill. I could be overthinking it and it was a total glitch

I suppose if you are really lucky you'll receive an update via SOTA quickly enough to be saved before you reach the bottom!
