I’ve had the privilege of owning and using these Land Rovers professionally and personally. I find that most people (as witnessed in many videos) do not make use of Terrain Response and so many Land Rovers are specified with no low range, no eDiff and standard all season tyres with big rims. In my experience, the current models respond best to steady constant throttle for assents and each terrain response setting feels different as it alters a range of parameters including initial locking of differentials, starting gear selection, gear change points in auto and the amount of permitted wheel spin before brake traction control kicks in. Info is on the display screens. Hill descent control and low traction launch tend to be underutilised too. Some settings can be useful on road too of course. Auto Terrain Response also invariably makes a good job of working out what settings to apply and will default to first low with Diffs locked when challenged. I do think the D5 and L663 Defender are great ‘out of the box’ and the D5 is typically underrated as it is practical with only a more limited departure angle than the L663. Then there’s the 900mm wading depth without wet feet! I’m loving your tests, thank you!
I’m 200,000 miles and 10 years into my diesel Discovery 4 and it’s been bulletproof. Love it.
Love watching comparisons like this where you see just how well the cars systems do respond. I never felt wanting in my d3 without rear locker but would have had one if it were available in the used cars I looked at.
The D4 was the pinnacle of modern LR's for an offroad vehicle IMO. The new 'Defender' doesn't really improve anything - and arguably the lack of aftermarket support means the D4 is still the vehicle of choice between the two if you want offroad capability with comfort and practical touring design. The fact that now 13 years after it was released (even longer if you consider the D3/LR3 was essentially same platform) it is still keeping up with brand new vehicles is testament to the quality of design and innovation at the time (even if build quality and reliability isn't always to the same standard).
I agree, the D3 was light years ahead of the market. Just cannot bear that ticking time bomb which is the TDV6.
@@nnoddy8161 Or the other issues,although ours was a D4.A great touring vehicle,shame they went to the D5,a revamped D4 would have been a much better seller.
D4 was an awesome tourer, but the new Defender is much more polished in every way. Plus the new defender has a ton of aftermarket gear nowadays so it’s another great tourer if the budget can extend
@@Dorko85less practical rear opening and space though. The tailgate bench is sorely missed.
@@offroadingfoz actually 100% correct - loved the split tail gate!
Great side by side comparisons and smart to add a variety of vehicles to benchmark the Discos. Thank you!
Very interesting! The Land Rovers did amazingly well.
That's because they weren't against Real off-roaders like a Jeep Wrangler Rubicon or a Ford Bronco Badlands. Even the new Defender with a rear Locker can't do the Rubicon Trail but the Jeep and the Ford can not the Jeep and the Ford in this video but real off-road ones
Very good. Disco 4/5 traction is excellent. I grudgingly had to admit that my D5 trumped my Defender in low grip scenarios and that TR2 could do a better job than me finding marginal traction... Also worth pointing out how capable Disco is on road and towing - a very broad range of dynamic capabilities. My issue with Disco is ultimate lack of axle travel, substantial R overhang and the lower suspension arms hanging up early in ruts/soft conditions. Oh and complexity, unreliability, difficulty of maintenance (D4 especially), tyre choice etc etc etc...
Thanks again great video, love my D4!
Such a great idea to chuck in the Jeep for comparison
That Jeep looks like quadra track 2 only. I do not see off road badge on front fender. Quadra drive 2 should show off road badge. But regardless that reactive traction BLD system is way slower compared to Range and Land Rover. That's the reason I gave 2021 Grand Cherokee QT2 to my kid. 😂 I jumped straight to Rubicon "with both differentials open, it is 3 times faster traction response time of BLD electronics compared to grand Cherokee. Sway bar disconnect. Now, there is something that despite I work in sales for Jeep Dodge over 2 decades' I had no idea that models newer than 2020 come with "fussion" of crawl electronic mode with rear and front locking differentials. When You engage 4wd low, disconnect sway bar, lock front and rear diffs, press off road plus button, at steep loose surface you hear same "land cruiser" crawl brake sound "trrrr trrr trrr". Literally is trying to regulate any unnecessary wheel spin, despite diffs are looked.
Better yet let's get a new Defender and take it against a new Jeep Wrangler Rubicon and a new Ford Bronco Badlands and the defender not make it
Many people ask, "Why would you ever drive such an unreliable vehicle". Because of this video. You can't add capability to a lot of vehicles on the market. But most Rovers come with all the capability you need from the factory. Saves you from having to "build" an offroader.
It's impressive isn't it...I threw the others in as I realised people wouldn't know how tough that hill is.
Or unless you buy a factory Jeep Rubicon or a factory Bronco Badlands then you can have something way more capable then all of these Rovers with lots of articulation and comes with better tires and larger tires smaller Wheels. I drive a Land Rover BTW so I'm not knocking them but over here in America you can't believe what a factory full-size Bronco and a factory Jeep Wrangler Rubicon can do on the Rubicon Trail that no stock Land Rover can even complete. Nor would you believe the test ground that she puts Wranglers through crawling Boulders and rocks and really dangerous things instead of a tailor-made course going through mud it's hard underneath and really steep cement descent to look cool and grass that they know they're not going to get stuck in
@ronaldrrootiii6040 I've recovered a number of Broncos and 100s of Wranglers. I've recovered 1 land rover in 13 years. I've wheeled with both Jeeps and Broncos and the New Defender at the same event. It's hard to say they are head and shoulders more capable. It really boils down to the wheel size. 35s are better than 33s. Each tire size increases your capability tremendously (until things break).
Nice breakdown 👍🏼
Had a 2013 LR4 went to Diso 5, I only hope they bring back a square body Discovery. Great work
Square body? No way that’s gonna happen. Much less aerodynamic.
@@jerrymyahzcat it's hip to be square
Loving these short comparison videos. Thx for posting. Watching the different makes, it appears to me that the speed the BTC reacts to the terrain and traction goes a fair way to determine how far the vehicle gets up. As a 150 Series Prado owner would love to see how this vehicle goes in one of these comparison.
Cheers
I have a 150 Prado video too on that hill...
Had a D4 with E diff, for almost 10yrs.I found even in soft sand,once forward motion stopped,rock crawl would on occasions get it out.Looking at the GAP tool,which is a scan tool for late model LRs,it is interesting that the E diff does operate at low % at times on the bitumen .It would have been interesting to compare the LRs to an LC200 or 300,which are probably the only other vehicles that are just as capable,and in the same class,particularly the 300.
See my other video for LC300 vs Defender....
Great comparison!
Thanks!
Awesome videos. Some other aspects of TRS are how it manages Stability control. In Mud & Ruts for example, if you are on road tyres on wet slippery mud, you’ll find it will kill the power and make the throttle pedal feel dead. Not an issue so much on dry terrain, but very evident in typical British muddy tracks.
There is also a comfort thing around the throttle too. Was with a friend driving over a ploughed field. He had it in Mud & Ruts (L320 RRS) and found the throttle was too sharp making it an unpleasant bobbing and pulsing progress. I advised him to try the Snow & Ice mode as it desensitised the throttle pedal. Which made for much smoother and comfortable progress. But I guess not an aspect that is as evident on camera, but makes a big difference to the occupants.
Rock Crawl mode is supposed to give the softest or longest pedal travel for that reason.
Thank you very helpful
Glad it helped please share!
Nice video always wanted that someone will create that , hope we will see more content about disco 5
You will
love to see a L322 Range Rover in the mix as well
For all of 'JLR's other faults, which are considerable, they do make a good BTC system.
Great video, thanks for putting this test together. Both the D4 and D5 are very impressive… Do you happen to know what tire size the white D4 at 8:10 is running? Looks like they’re still running the 19s and doing reasonsbly well with them. I’m trying to see what the largest/most off-road suitbale 19” tire is that i can run on mine.
You are aware that the eLocker on these vehicles isn’t an on/off type. It’s a variable progressive one like the centre diff.
I really enjoy my Discovery Sport which has no cross-axle lockers and only the centre variable “diff”. It doesn’t have air suspension but has great wheel travel for a fully independent suspension vehicle. It’s cherry capable and the TR is excellent. It would likely do the steepness of this hill but not the terrain of it due to clearance (so if the surface was flatter or graded I reckon it would go up as can ascend up to 45° with enough traction).
I am aware yes
Hi Robert, in my L319 D4 with an e-diff I can see on the 4x4 centre screen display that the diff locking varies depending on the grip available.
So when 4 wheel driving the rear differential dash display indicates first in green then changes to orange when the terrain is more slippery, so partially locked, and then to red when fully locked. Sorry, I can’t explain this in any greater depth but I’m sure there are others out there who know and understand more about this.
The extent of locking is determined by the cars software I believe. Cheers, David
Correct. I said in a post just now that the eLockers aren’t on/off but are variable progressive same as the centre diff.
On this topic a point of confusion is when people say "turn the traction control off" when really it's the DSC (Dynamic Stability Control) that must be turned off as it will de-power the drive to the wheels. The instruction to turn off DSC is clearly given when you do the Land Rover Experience driver training day, but on the day I attended there was no clarification of the various modes. All I can determine is that the further clockwise you go on the dial the quicker the clamping response is.
Absolutely DSC (ESC) is different to brake traction control, and in LRs you can only reduce not eliminate it!
Robert, Great video comparison. Would love to see a similar comparison of the Toyota 5th Gen 4Runner and Tacoma modes.
We don't have those in Australia
Hi Robert, thanks again for a very informative video. You show the (older) Everest struggling on this hill, does the Next Gen Ranger/Everest have Brake Traction Control?
Yes all do
I’ve got a 2017 Range Rover Sport without e lock. Pretty sure has the same terrain response system as the vehicles in your comparison. Very capable off road.
It has, yes
Great! Land Cruiser 150, 200 and 300 next time please 😇
Looking forward to the Defender version of this
Yes and a real Jeep like a Rubicon Wrangler or a Bronco Badlands it will spank the new Defender which can't even do the Rubicon Trail here in America but the Ford and the Jeep can in Factory form
A SXS would spank the Jeep rubicon and Bronco
@@LetsGo-wf1dy yeah of course LOL🤣 but we are talking about SUVs that carry people and toe things and have solid doors and windows and air conditioning and room for cargo LOL and you know even some sxs kind of suck on certain rock crawling terrain that a solid axle Jeep would do better on. I live in a state with some of the best ones in the entire country I see it all the time every weekend
With the launch of defender, I don’t see any reason for anyone to buy disco over def, unless they have a narrow gate or they want a cheaper option.
Yes that’s what I’m getting at, but what is the hydraulic pressure of the system and is it the same all the time? What I mean is sometimes the system and doesn’t matter what manufacturer, has less clamping ability on the rotors.
I think this is a great video but the only problem I have with it is those bald tires they have because I feel as though they don't let modes that are being investigated really show a difference when the tire just wants to slide pretty much no matter what because it's just so bald and not made to be doing what is doing in the video. Being an avid off-roader every single weekend doing really tough things and running mud terrain tires 365 days a year in the desert with the air pressure down to 20 I notice differences in things much better because the tires aren't a limiting factor.
Hello, I have recently bought a LR Discovery 5 and am curious about capabilities and I wonder if you drive parallel to a hill how many degrees of side angle it can tolerate and do not roll over.. Thanks, by the way the video is great..
About 45 in ideal circumstances but try to limit to 30 for most offroad situations
I"m trying to know if the D5 had All-Terrain Tires ? also what was the PSI ? I those make a huge difference. Great video comparison.
All at road pressures and there is enough traction to ascend so the limitation isn't tyres.
Hi Robert, this is a great comparison and an excellent testimony how well the D4 is running up this hill. Do you have any comparison between the D4 and the Grenadier at this specific hill?
Sorry no
@@L2SFBCI do stiil have my 2016 D4 and this car is so capable off-road but also one of the best touring vehicles with lots of space. Now, since two months owning the Grenadier, these two car are quite so different, I really can't compare it - loving both of them! The Grenadier is more rough but great for long distance touring, way better as the D4 on B road, dirt roads and gravel. D4 is winning on tarmac and as a daily driver. So, would be interesting to see a comparison for a few offroad tasks. I guess it's hard to beet the TC of the D4, but the Grenadier with its three lockers and the more robust design will be a keeper for me!
Sorry prefer the D5 here over any other vehicles depicted.
I suspect in different modes there is higher or lower line pressure going to each brake, I’d love to have pressure gauges on each line to prove it but not easy.
It doesn't work that way, it varies the braking (line) pressure until the wheel sensors show that the wheel had stopped spinning. Wheel spin feedback is the control outcome in the closed loop.
thanks! the same with a Ckerokee KL ???
8: 30 in the wild. 🤗
Would be interested to see how my 2009 Defender 110 with TC but no locker goes on the same hill.
Very well, probably beat the Grenadier!
Hello. How to lock the rear differential on a Discovery 5? Can’t seem to find this option on my car.
Cannot be manually locked. Computer controlled only.
Awesome video, again! How would a Toyota 150 / 200 / 250 / 300 perform on this hill? I’m guessing far worse than the land rovers.
No check out my other Hill of Truth videos
Your know if a wheel doesn't have any traction it's going to spin whether the differential is locked or not.
Maybe when the rear Locker was on the right rear wasn't spinning Because the actual Center lock wasn't even locked in the transfer case
Wouldn't make a difference
which is the best 4x4?
Jeep Wrangler Rubicon and Bronco Badlands hahaha by far
Much better performance with a rear-locking diff, well worth it for the new Defender. Dreadful performance from that Jeep & Ford.
Definitely the ediff is worth it in LRs!
But you need to get a Defender and then use a real Jeep which is a Rubicon Wrangler and a real Ford which is a bronco Badlands and watch the defender get spanked which is proven because it can't even do the Rubicon Trail in Factory the Ford and the Jeep can
The modes are all a scam. Worst 4X4 by far
Best 4x4xFar 💪🏻
🤣@@pauldejager2476
@@pauldejager2476if they're the best why can't any of them do the Rubicon Trail in Factory form the way a Jeep Rubicon Wrangler can and a Bronco Badlands can? Maybe because they don't have the articulation the small wheels the big tires and the front and rear lockers needed so in that case they're not the best when there really is better things all you have to do is look it up and watch
The only thing they are good at honestly is they have pretty high towing capability for how luxurious and comfortable they are and when you put some all-terrain tires even though they are 20s or 18s they can do some pretty good off-roading as long as you don't get them on a really cross axle situation that they don't have as much in the UK compared to the United States or australia. But otherwise considering all the other things they do in such comfort and luxury yeah they are the best in that category there's no other fancy SUVs that can tow a lot that can crawl up things really slow like that except for a G wagon but that's way better and way more expensive LOL
