I thought that too, and I also think he was still in high range until the final drop
Even so it does show the capabilities Rob Smith

I initially tried to go through the course slowly, but got stuck and had to be winched out (much to the enjoyment of the Jeep crew). You see those elephant footprints are in LOOSE sand so you have to give gas and STAY on the gas to keep momentum otherwise you just bog down. On my 4th try I got through the entire course without a hitch. No other unmodified vehicle was able to do that.
The standard Jeeps were all only able to get through the "baby course" next door. There were 2 very modified Commanders there with lift kits, ARB bars etc. They were very impressive through the course, but a 5,7l hemi sucks gas at a frightening rate!

Discovery 3 at the Jeep Halloween day.
The Jeep dealership at Century City very kindly allowed me to use their course yesterday during their marketing open day for Halloween. There were 2 courses; a simple course and a harder more extreme course. The simple course was very easy, but the other course was tough. I initially tried to go through the course slowly, but got stuck and had to be winched out (much to the enjoyment of the Jeep crew).

Nope, Low Range sand in the elephant prints, Mud and Ruts in some of the other stuff.
Command shift 1st gear, Low Range, HDC on for the steep descents (with feet off the pedals of course).

I think you mean a lockable rear diff? This is what all SA Disco 3's have.
Excellent explanation stolen from member Saremlight:
Any 4-wheel drive vehicle has to have differentials to allow the wheels to turn independently when going around corners. Without some means of locking the differentials, all the engine's torque will go to the wheel with the least resistance, so if one wheel is in the air or on a slippery surface it will just spin with no traction.
All D3s have an electronically controlled centre differential which senses when the wheels are slipping alot (also guided by your selection on the terrain response dial) and locks the front and rear axles together. That stops one wheel from spinning away, but there are situations where that alone won't help (for example where the vehicle is "cross-axled" with one front and one rear wheel in the air, both would just spin).
Fortunately, all D3s also have traction control - the computer can sense which wheels are spinning from the wheel speed sensors (originally intended for ABS) and can apply the brake to each spinning wheel. On soft ground you can see this happening and it gives enough traction for a standard D3 to get through some amazingly challenging terrain.
There is also an optional "active rear differential" - I think this is what you mean by the e-diff. Depending on the terrain resplonse setting, this uses a clutch to "pre-load" the differential or lock it completely, linking the two rear wheels directly together so they can't spin independently. The "rock crawl" setting does this.
Do you need it? Probably not, but if you're going to drive on rocks or sand I can see it being a good thing. And it'll save brake wear. I wouldn't make a decision between two D3s solely on one of them having it though.
The HSE gives you a nice 4x4 info display that show when each diff is working, but it won't get anywhere that an SE wouldnt. Makes you feel good knowing it's there and working though
