Thread: terrain response

That's an awesome example Gordon......now if the defender came with the terrain response, 3 litre motor, 17 inch rims, with its manly ruggedness, it would be one hell of a weapon.

I would not have believed this outcome without your video.

Brett.....

I'm aware the defender has TC, I owned a 2004 110 Xtreme before my D4. At the top of that incline the vehicle was crossed up, with the front left & I assume if the driver locked the centre, the rear right spinning. I've been in a similar situation & the TC has assisted.

I also noticed, as I drove a new 110 at the stealership last week, TC is purchased as an option. Did the defender in the video actually have TC installed?

You are confusing "Terrain Response" with "Traction Control". The new Puma Defenders come with traction control as standard. They do not have the option for terrain response (none of the Defenders ever had).

The driver was a qualified trainer and knew how to set up the vehicle. It is simply that the Defender's traction control will not _always_ brake the spinning wheel effectively. In some situations it will, in this instance it couldn't. On the other hand, in the RRS, Terrain Response allows you to "program" the aggressiveness of the traction control (amongst other parameters), and in Rock-Crawl the response is similar to a locked diff.

Cheers,

Ok got it, I was of the belief TC was a average 'all purpose' version of TR, I was considering a new defender 110 but I don't think I will now.. A 90 may be on the cards though..

Rob

Gordon,

You should show them the video of the Defender struggling on the big sand hill when both D4's and the RRS just drove straight up! My D4 weighs 2740 kg plus the three people we had, fuel and extra steel spare on the Kaymar bar and we had no trouble getting up any of the sand hills or the tough bits of the Power Line track.

Does this sound normal? Should the car have stalled? Should i have had DSC off?

I would appreciate any comments as i haven't done much offroading in the D4 and my mates have been laughing at me.......

I realise some decent offroad rubber would help....

Cheers

Lucas,

On Sunday, as I was staying in the Blue Mountains I loaded the D3 with 5 kids and mate, so 7 up and had a play around Mt Walker at the back of Lithgow for a few hours.

I was by myself so did not want to tackle anything to silly. but still had a couple of interesting climbs as it was a bit greasy, I run AT tyres, but as I had not packed the compressor did not let any air out so was just running highway pressure.

I was climbing some steep sections under the power lines, for those that know the area I was in Rock Crawl, DSC (DEFINITELY OFF) and low range 1 or 2.

In the first instance I simply had to back up a bit (not fun with a nervous passenger thinking I am going to kill us all and 5 kids screaming out they are going to die) and get a bit of momentum to climb over a little rock step.

Second was deeper into the power lines and probably a bit more difficult that I recalled from recent trips. Actually need to get our and do a little road building to get up. I managed to stall twice in this section which was new for me but simple enough to restart, check DSC OFF and go again. It took a good 5 mins of mucking around to get up this climb as going back down was not really an option.

Anyway point of the story is;

1. ALWAYS CHECK DSC OFF
2. Momentum is your friend - with in reason.
3. Rock Crawl is best when it get tough.

That Defender did not appear to have any traction control working to me, though I am not a TC expert.
I would have expected the same as the RRS, the unloaded wheel to be braked on and off, and that did not seem to happen at any time.

See Gordon's response re TC earlier in this thread.

On another bit of muddy track on the same drive where the axles were not so badly crossed up you could see the traction control working on the lifted front wheel of the Defender. However, in the video, with two diagonal wheels with zero traction, the TC was not agressive enough to do much, as Gordon said.
