Old but gold ;)
Благодарен команде за вашу работу 👍🏻 👍🏻 👍🏻 Лично для меня, один из любимых каналов. 👍👍👍👍👍👍👍
Really cool to see how they reacts 👌🏻
Tomorrow I get a 2003 Volvo XC70. It only has 112K miles on it and looks well maintained. I'm a little scared cause I don't know much about cars. Wish me luck.
You don’t need luck with a Volvo , my XC 70 done 266,000 miles , sweet as a nut 🤙
Visco win all, but not the last test... Both are good...
Hier sieht man deutlich das jedes System seine Vor-und Nachteile hat. 👍🏻
Keeping track of the Maxiecu output values has been a great addition to the test, thank you! This goes to show how an essentially identical vehicle with different AWD systems treats different wheel slip situations completely differently (along with the limitations of a viscous coupling to sending torque to the rear axle in this case). I know this is a bit off-topic for this channel, but I really wish you were a sort of independent car review channel like Marek to also hear your personal opinions of the vehicles you test.
Thanks! When it comes to personal opinions of the vehicles we test - we don't get these cars for long tests, they belong to private users. We love to ask them about their experiences but we cannot make any serious winter or offroad test drives and that's why... We don't talk in the videos 🙂
@@4x4.tests.on.rollers This is exactly why I think 4x4 tests on rollers deserves a separate review channel where manufacturers send you vehicles for 2-3 weeks to review under all circumstances you see fit.
@@OnurKennethYumurtaci Manufacturers ain't that brave 😉
@@4x4.tests.on.rollers is it some kind of service that you provide to these private users?
Dzięki!
To get visco out of the last situation you need to pull the parking brake. It will stop thr free wheel giving traction to the one on the hard surface. But other than the last test visco seems to react faster than haldex. Ive got a 2001 XC70 with visco. Im quite impressed what it can do on sandy hills and in the snow
Drivers tried that, it didn't help.
Єрунда.. вся причина не в віско, а в різних системах track/dstc. Модифікація з віско має більш жорсткий режим роботи імітації блокування.. тому машина легше зїзджає при контакті переднього колеса. Але на задню вісь, машина з віско, імітації немає ВЗАГАЛІ.
В машини з dstcімітація більо мяка. Тому зїхати одним переднім колесом їй важче. Але в неї є імітація блокування і на задню ось.. тому вона вмії зїзджати за рахунок заднього колеса.
Віско має, ЗАВЖДИ, паразитний момент на задню вісь .. тому їй легше на ожеледиці і піску, так як халдекс постійно вмикається-вимикається. Проте на важких грунтах віско передає момент з більшим запізненням, від чого машина може закопатись. Халдекс працює швидше.
Халдекс вмикається швидко з ударами, від чого страждає трансмісія. Віско працює мяко - трансмісія страждає менше.
Тому, раджу Вам, більш детально розібратись в повному приводі.
Is the 2001 xc really open diff rear? Kind of wild how the 1165 diff in a 1996 850awd is a locking diff and would get out of this 😉
Fajna prezentacja, i wszystko widac, a co do auta to juz wiem ktore kupic 😉
Które? Mnie się podobają właśnie xc70 :)
Early P2 came with VISCO? i wasn't aware!
Would LOVE to see the astro van old t case (a viscous system) vs the newer ones that had a motor to engage the first axle when slip was detected
Or similarly the awd np149 vs the 4x4 in the gmt800 rigs.
I'm a huge proponent of the viscous systems for snow driving.
It will be extremely hard to find these cars...
You don’t see souch cars in Europe at all.

Would be awesome if you could do roller test with VW Golf Alltrack (Mk8) vs Audi A4 allroad (Ultra). Or any system versus Golf MK8 4motion. By the way, do you know which gen Haldex is in the new Alltrack 2021? Thanks!
Audi A4 Allroad with Quattro Ultra is already on my channel. If we find Golf, we will test it for sure 🙂 It should have haldex 5 with newest modifications.
So which is better? Looks like the haldex

VC on P2s is still haldex (updated from the 98-00 Haldex VC), and it appears to respond faster than H3 on some of these tests.
VC is not haldex, these are different clutch-packs.
@@4x4.tests.on.rollers 98-00 V70/ S70 used a haldex VC, 01-03 used the same VC but with a solenoid controlling the clutch packs. There are a few articles out there talking about it. They can be found on FCP and I believe Swedespeed
@@nilssjoberg2522 Viscous coupling is not haldex. That's completely different unit from different producer.
@@4x4.tests.on.rollers Unless FCP is wrong, which is possible, The article states First Generation Haldex was used in the V70XC and R from 98-00.
@@nilssjoberg2522 I don't know what FCP writes but I know what's under the car - that is viscous coupling: facebook.com/StacjaKontroliTrakcji/posts/1181163429028508
👍
What is causing the difference? I would assume that traction control is the biggest difference between them rather than distrubution front to back? What are your thoughts?
Traction Control is the clue. It looks that visco version doesn't have it on rear axle (or it is very limited) but overall TC operation is faster than in haldex version.
If you step litle on Brake or hand Brake you can go also with 4x2 😉
@@wenzelvwvw Unless there is brake priority over acceleration pedal... Besides 4x2 cars are also equipeed with TC.
@@4x4.tests.on.rollers What about Volvo TRACS/STC system that would working like electronic LSD? Seems it the VISCO car have it broken. In my V70 AWD VISCO+TRACS works perfectly.
@@KECZO2 It's not broken, it works great - otherwise car would fail diagonal or lateral tests.
So your switching between AWD systems? Have you took them out on the trails?
Comparing two awd systems. I didn't take them on trails.
Is it ok to run the engine a long time on rollers. I see for the visco volvo in the last test that the front tires are spinning at different speed. So the front diff is working. I am asking this because i know that we need to match tires on a 4x4 car otherwise you will damage the diff. So is it ok to let it spin like in the last the for the visco volvo?
Wheels are always spinning at different speed until the diff is locked. The question is how big the difference is. It is not recommended to spin it with high difference for a long time but on rollers there's very low load so nothing can happen.
@@4x4.tests.on.rollers ok. Ty!
Looks like perhaps the rear diff is open on the '07 and possibly a viscous coupling on the '01? The '07 doesn't transfer torque side to side as well, but is quicker front to rear.
Both have open rear diffs. Side to side torque transfer is based on brake system.
My xc70 with 3rd haldex works perfectly… cant understand why here is this slipping and no response…
@@chrissbanzai What "no response" are you talking about?
Is this rear viscous a faulty? Pretty old cars now so could it need a service in reality?
Why do you think it may be faulty? It works very well.
Would it be possible to fit a aftermarket locker to these systems
Anything is possible but it won't be simple. It is a rare project. Your sources will be the German brands for parts.
These cars are nit used in motorsport or off road. Yiu will not find any lockers for These cars.
A jakieś nowsze? Wersje po 2015 jeżdżą tak samo?
Z nowszych znajdziesz u nas na kanale np. S60, V60, V90, XC90.
i think they are both haldex (gen2 and gen 3) the vicious was on the v70 p1\v70 xc
Nope, here's photo sent by the owner of 2001 - this car for sure has viscous coupling: facebook.com/StacjaKontroliTrakcji/posts/1181163429028508
What we see here, is that the average driver, is not going to notice any difference in practice. We have an xc70 2005. Has it been great on long drives - absolutely. Has the AWD helped - absolutely. Is it an off road vehicle - no. If you find yourself in a situation where only 1 wheel has traction, then you have already messed up, and should not be there. Is the AWD going to save you - probably not.
Really nice test, just sold my Volvo for a first gen Sorento, immediate comming to this channel to see how that one preform, sadly couldn't find first gen of that car =) maybe in the future ^^,
Sadly first generation of Sorento wasn't tested yet.

So everyone says you need the latest version Haldex, but when i see this...... I don't thing i want to buy a 2006 XC70 anymore
I have a 2006 XC70 and with good snow tires it is unstoppable. Did the Coquihalla Pass in a blizzard. People were turning back. Trucks were putting on chains. My XC70 got me through. It wasn't a cake walk but is wasn't a struggle. Heard the traction control working quite a bit. It just kept going and was easy to control. I encountered every kind of winter treachery on that winter drive from Vancouver to Winnipeg and it was rock solid. Passed lots of cars and trucks in the ditches.
Nice work! Watching this and the Suzuki Ignis test I undertand that visco allways fails giving torque to just a Rear wheel. If you need to add a FWD to the comparison (guess it does not make sense) you can count with mine.
Thanks! When it comes to visco - hard question, I suspect that traction control may work only at front axle.
FWD for comparison would be nice, come for the test 🙂
@@4x4.tests.on.rollers This is exactly the question I was asking myself. Not easy to answer; visco not transmitting enough torque or traction control not active enough on the rear wheels. Maybe a bit of both.
@@Softroader Considering the fact that there are cars with diff lock on the axle powered by visco, I would say that there is no problem with visco torque. I would rather say that TC intervention is limited to allow visco operation or it is completely off on visco axle.
@@4x4.tests.on.rollers I think there is indeed a limitation in the operation of the traction control on the rear axle. This is something that seems to be common, and not only with the viscous couplings. With the P2 platform XC70 , it was announced that "TRACS" traction control was extended to all 4 wheels (it only worked on the front wheels on the P80 platform) to replace the Eaton G80 self-locking differential.
@@4x4.tests.on.rollers but @soft: you mean front or read diff not central one, right? That's the point, rear wheels on a Central Differential with an open rear diff and no traction control slips. A FWD or RWD with visco, torsen or any kind of Limited Slip Diff won't do that thing the same wat it won't happen with a efficent electronic traction control. Another point is that visco is... Let's say unpredictible, and not as efficent as other systems, you can't determine how much torque goes to the rear axle, it is afected by too many external.factors as: if it's the last test done overheating, the maintenance done to the diff... So it would be needed to do more tests to be 100% sure why it happens and even know more data, in example in the case of the Volvo if stc or dstc also has sensors in the rear wheels to ensure a better traction.
Do którego roku było montowane Visco?
wygląda, że lepiej sobiej radzi to volvo, jak np. testowana u ciebie Alfa Romeo Q4 na torsenie
@@hbo7799 Mniej więcej do 2002. Trzeba przyznać, że kontrola trakcji działa tu bardzo dobrze.
Visco got so much shit but it turns out it is bot that bad . Not bad at all!
Is it normal for the 3 wheels rotating while the drivers side rear was not?
Yes, that's how open differentials work.
@@4x4.tests.on.rollers On the hoist, my xc70 spins all wheels, but the drivers rear hesitates and is the last to spin. Was told by my mechanic that I only have 2wd because my DEM was not communicating. Does having the vehicle on the ground change things?
@@jonjackson1901If it's haldex then communication is responsible for powering rear axle, not the wheels. If one wheel doesn't spin then something is resisting, like bearing, brake etc.
@@4x4.tests.on.rollers How would back wheels spin if no communication fromDEM?
@@jonjackson1901 Every clutch-pack has some internal friction.
visco -no service need, haldex , miss a oilchange and yoar haldex is dead at 250 000 , seen viscos going over 450 000 km without problems
I think rear visco would need a service
So mine is a 2007, so Haldex 3?
Correct.
Jakie wnioski?
W wersji z wisko, kontrola trakcji reaguje szybciej, ale układ awd jako całość reaguje wolniej i przekazuje mniej momentu na tył. Możliwe też, że przy wisko, kontrola trakcji działa tylko na osi przedniej.
The visco in the last part would have come out if appling the a bit of handbraking
Some drivers tried and it never worked...
Strange because they’re all Haldex. At least my 2002/3/5/6 were.
2001 is visco.
up to 05/2003 was visco
What was the point of the last test?
The same as any other.
@@4x4.tests.on.rollers I meant since it was just free spinning.
@@Chrissurf It passed all tests except the last one. Car was not able to get out of the situation when only one rear wheel had grip.
@@4x4.tests.on.rollers ok my mistake I thought it was on four rollers ...I have the VC on my 02 ...
@@Chrissurf No problem 🙂
Виско как Калашников, надёжне в разы халдекса.
Haldex lepszy?
W tym przypadku tak, potrafi przenieść na tył więcej momentu niż wisko.
