Thanks Jim & Karen, great video of the day. I believe plans are already a foot for the next one, hope you have BB running again for that. Always great to see these vehicles make things look easy.
I love these videos. It's amazing to see the differences in traction control between the D4, D3, and Rangey. They certainly have been improving. That poor rover with it's wheel spin. And the difference between the D4 and D3 is noticeable as well. I hope the D4 isn't the last off road capable Discovery that we see.
Great video. I'm about to get rid of my old 4Runner and invest in a Dico4. with the 3.0 L engine. Would you see the big wheels as a big concern (in terms of finding good off-road tyres)?
Unfortunately Black Betty (the RRS you see struggling in the video) had probs with traction control that eventually resulted in shattering the front left CV not long after this. When we pulled it out, there was nothing but shards of metal left of the CV. In some sections the TC was working, and in others it failed to engage at all even though there were clearly traction problems.
Gday Jamie, a great video, hope all is working again on BB, and im really sorry to hear Monty isn't around anymore, cant imagine how you must feel, also it looks like im going to be getting a Disco4 TDV6. Cheers Dennis.
What was the final root cause of the TC problems on BB? I have an 06 Range Rover Sport Supercharged, and sometimes when only three wheels are on the ground, it seems to allow a lot more spin than those discovery 3's and 4's, before locking the wheel in the air sending the power to the wheel on the ground. Could too much rust between the wheel speed sensors and the hub where they mount cause a poor ground? I do not have any faults or lights on the vehicle. Maybe it's normal, I don't know. Do you have any thoughts?
Hi Sean, No reason provided for why this happens but your original theory is on the right path. TC is governed by sensors and if they happen to be adversely affected from either mud/rust/damage/misalignment or even just a sensor malfunction, then you are going to have problems with it. I am not convinced that ours is working 100% without faults and will continue to test it on our of road misadventures. Will keep you posted
The air suspension is better at articulation than straight coils as they are cross linked with a valve opening in low range. Coils won't work as well. The only problem with the air suspension is it takes moe pressure to gain height and you lose compliance as a result.
Have a good day! Great movie. Say for steel wheels 18 are on the Discovery 4? I want to put on my Discovery 4 sdv6 Cales 18, and drives can not find. Sorry for the wrong language, writing through an interpreter. Thank you who responded!
They run a 17" composite rim Yuri so they get a lot more tyre choices. You can only do that on the 2.7ltr model though. You need to run 18's on the 3litre due to the larger brakes.
For the amount of poor articulation these vehicles have, i have to say they handled the terrain quite well and was very surprised with how well they did. Has that got anything to do with the traction control side of things? Could this be the future for ifs? I do know that toyota grabbed 2 200 series recently and put them through there paces, 1 being the normal ifs set up and the other being a fully custom made solid axle set up and they said that because the ifs traction control aids worked so well there wasn't much of a difference between the two so they didn't think it was an expense worth going ahead with making the 200 series solid axle. Love your videos , keep them up mate!
It's definitely all about the traction and suspension systems. I saw the D4 on road tyres tackle muddy rutted tracks that older seriously modified vehicles struggled with. I'd have to say they are the best on-road/off-road combo vehicle on the market. There are limitations, but for most people, they will rarely find those boundaries a limitation to what they want to do with the car.
Hi what a nice adventure. I wish I can join. I have 2013 D4 5L HSE, its 20" rim with the tires 275, 40, 20 is really pain in the sand. Would you suggest me of any tires type I can fit on them. And don't harm the car.
Sorry for the late reply mate. We also have V8 D4. Very limited when it comes to wheel options due to the larger brakes. You didn't hear it from me but some people have been known to switch the brakes over to the TDV6 version and run 18inch rims
It wasn't the turbo. Still not exactly sure what caused it but could have been the traction control system trying to compensate for the damage to the CV.
Wonderful vid!!! Thanks for sharing one more time!! I know BB is a master.... But please don't kill her!! All RRS around the world believe in her!!! Good look, and hope see BB soon! You are our inspiration! m.facebook.com/story.php?story_fbid=10152483749488829&id=542143828 Regards from England!! Pd. try to put the supercharged model transmissions, or a normal v8 petrol transmissions... I think it's stronger... Ask about it! Great day, dramatical scene, thanks!
Thx Marcos. BB is fine. Once I realised there were traction control probs, I should have really sat that run out, but having travelled all the way there, I couldn't resist ;-)
There is hardly any flex on the suspensions of any of these vehicles, is that for a specific reason? If a tire is not touching, you aren't getting traction.
