Nie znam drugiego takiego kanału, który by tak dokładnie testował te systemy
You know they are more than capable when the wheel not on rollers spins on dry asphalt.
Yeah and that would be better to put all wheels on roller but to lock those who should provide grip. The problem is that it just leaves marginal load on the wheel touching the ground, preventing it from moving the car alone. With all wheels on rollers, at least the wheel loads are the same and you really see if one wheel alone can move the car forward.
@@Jehco14 Wheels on rollers are 30-35 mm above the payment.
@@4x4.tests.on.rollers So for a 40 N/mm (front wheel rate for the focus), assuming the car would be fully horizontal at the roller level (which it isn't obviously), that's about 1400 N load deficit on the tyre, which is a significant part of the corner load. I think with the normal wheel load when the car is on a flat ground, any wheel should be able to drive the car forward (assuming the differential is sending sufficient torque).
@@Jehco14 I'm not familiar with these numbers but the problem that we see in this video (unloaded wheels slipping) is rather rare in these tests. It usually concerns sport cars with stiff chasis/suspension or cars with bald tyres. All in all - any wheel should be able to drive the car forward, assuming the differential is sending sufficient torque - and that is the point, not every diff/awd system does that.
@@4x4.tests.on.rollers maybe lower the tire pressures a bit
These vids are always getting better. Nice work
Good clip as always ! The 4WD on the Ford worked as expected. When I bought my RS for XMAS in 2017 and I went up a road covered in ice and snow, I saw what the car was capable of. I had people spin out in front of me while the RS was planted and worked overtime.
PS. The front nose of the vehicle also acted as a plough 😂.
Thanks 🙂
Where did you take money fór it? I want RS too 🥺
Both cars did well, perhaps better than some suv
Very interesting test! Excellent video!
Thank you! More tests coming soon!
You can try applying the brake and throttle together when you were stucked on the roller, like the GR Yaris in the video. Because that would give the LSD a "preload" force to enable it to send more torque to the better gripped tyre. But this trick is only useful on mechanically torque-sensitive differential, like Torsen or Clutch-based LSD. For cars with open differential that may not work.
That's not the point of the test, we are checking if system is able to do that by itself. We tried the trick a few times, including the car with torsen differential, it didn't help.
Jak zwykle good job
A jak tam rozbita rzeczywistość? 😉 Akurat GR Yaris wygląda na jednego z tych, gdzie ESP OFF = TC OFF.
@@4x4.tests.on.rollers nie wiem czy to gadka na publiczną rozmowę. 😜
Dziś jeździłem autem gdzie przyciskiem wyłącza się kontrolę trakcji. Hyundaie chyba wszystkie tak mają. Z jednej strony nadal bym polemizował, z drugiej nie jestem osobą tak zawziętą, że pomijam to co widzę i czytam bo mi nie pasuje. Więc.... no temat na dłuższą dyskusję. Może kiedyś się spotkamy 😉
@@marcinobodzinski52 Nie miałem okazji testować, ale wg instrukcji - dokładnie tak mają Hyundaie 🙂

looking forward for a test with the Corolla GR that is in the works as we speak!
won't happen. GR Corolla will bypass Europe
@@f00lxpl that is sooo sad!
@@midnighthoon788 it is...
It's the same AWD system anyways, it will most likely be very similar in performance
The GR Corolla sucks dude...
Great video! Kinda surprised the Yaris had so much trouble with the 1 front 2 rear on roller test. I thought that torsen diff in the front would've worked better. Somehow the focus' open diff with brake modulation was better, lol.
Well, almost zero torque at the spinning wheel multiplied by some factor is still pretty much zero.
@@cmdrratzass7305 Two torsens are enough to move the car forward. One is not enough but that's not the point 🙂
@@cmdrratzass7305 The torsen don't work on the principle of having more torque on one side. It works on the basis of preventing one wheel to spin to fast in relation of the other wheel.
ruclips.net/video/JEiSTzK-A2A/видео.html
@@DengMam It is working on the principle of having more torque on side. There's a mistake in the video you linked, explained in the most popular comment - torsen never locks: ruclips.net/video/UlnGG4frZ68/видео.html
torsen diff dont work when one tire has absolute zero traction, for example, when one of the tire is lifted off the ground
Awesome videos! Hope you could do 2015+ WRX Vs WRX STI!
Thanks! I also hope for WRXs 🙂
+1. The WRX STI has a very trick AWD system unlike anything in Subaru's lineup. It would be interesting to see.
I'd like to see the new golf R vs A45s both with drift mode
Great video. As the Yaris was advertised as a rally inspired car and having 2 front and rear diff, I'm suprised to see it struggle with the front having no grip and the rear having grip on 1 wheel. The front of the RS is only an open diff but it seems ok when only one front wheel has grip.
And also you guys did the explanation of Yaris AWD, can you do one for the RS AWD as well?
Thanks. We'll try to do the video about RS to.
Great Video! And some weight on the Focus' back would've helped it 😂 like sitting in it??
Btw what's '2' in Torsen B (2,3:1) ??
Some weight, better tyre or no paint under rear wheel (white line) would be helpful 😉
TBR - Torque Bias Ratio - 2.3:1
thank you like always
and I can't wait for my gr but it was a bit disappointing how he handled your test
There's nothing to be disappointed - considering the fact that GR Yaris has performance awd system, it performed very very well.
@@4x4.tests.on.rollers hmmm
okay if you say that then I'm happy.
Hehe I'm coming from the off-road section and when I lock everything locks and there is no spin at all.
But I thought the fords system was a bit better programmed.
Anyway I'm still very happy with the gr should here soon. The test drive last Winter here in switzerland was awesome
@@51KTM51Hurricane Fords system is very well programmed, it was just missing grip 🙂
You don't buy an AWD performance car for offroad capabilities.
Remember though, that showed a situation with 3 wheels with zero grip, thats almost impossible in real life, plus you get a 261hp manual yaris which is pretty damn sick :D
Greetings from Ecuador.

More grip on the front axle which is what is needed since the cars have more weight on the front
Please do the Golf 8 R with performance pack! Would be interesting to see that new AWD system on test!
If I only find it... :)
I've been wondering this since the last video with the focus, is this focus RS stock? The rake is far higher than stock, seems to me that the front end sits way lower than stock, or the back end sits higher, which may explain why the rear wheel was getting almost no grip when the other side is raised.
The wheels and tires are also a big part and those are definitely not stock, seems to be winter tires, in winter as you can see from the snow piles in the background. The yaris was tested in either spring or summer as you can tell from the plants in the background, with most likely summer tires.
I'd be curious to see how a stock focus would perform, since this one was struggling with grip issues and that doesn't mean it's unable to send enough power to that rear wheel to break itself free.
This Focus is stock, still under warranty. It had winter tyres during the test, rather worn out. And it was standing at the white paint (line).
@@4x4.tests.on.rollers interesting, that would explain why it was not getting enough traction. The suspension still looks kinda off though, maybe it's just the lighting condition, but if not then the owner might want to have it checked out.
@@marcoling2173 Focus height looks 100% stock to me
Not sure if it was mentioned but it would have been a better outcome for the RS if you used one with a lsd. I think you mentioned this one didn’t. My 2018 LE came with one from the factory.
So much want for the yaris
Still looks like they performed better than alot of SUV’s.
because they are much lighter than any other huldex coupling type SUVs....
@@user-yq1pw6ew4o nope, because the ford has clutch packs on each individual rear wheel and because the yaris can over drive the rear axle, effectively they can act as either rear biased or front biased cars based on the situation, while most Csuvs are front biased predominantly, thus will struggle with a rear wheel on thee ground
Po torsenach w Yarisie spodziewałem się trochę więcej...poza tym napędy zdawały się gorzej radzić sobie z brakiem przyczepności im bardziej zaawansowany był program (na Track Expert bardzo późno załączały)
Track Expert (jak i ESP off) to całkowite odłączenie elektroniki hamującej koła (dotyczy tylko Yarisa), zatem wtedy właśnie możemy zobaczyć pracę torsenów. Dwa razem dają radę, natomiast jeden to za mało.
Torseny działają tu dokładnie tak, jak powinny. Dwa bez elektroniki dają radę tylko dlatego, że rolki dają jakiś minimalny opór. Gdyby dwa koła były całkiem w powietrzu, Yaris by nie ruszył bez lekkiej ingerencji ESP. Do jazdy wyczynowej, gdzie całkowity brak trakcji dwóch kół raczej nie występuje, to rozwiązanie super się sprawdza, wyciskając cenne sekundy na krętym torze. Dodatkowo, przy otwartych dyfrach, hamulce muszą dość mocno dohamowywać koła, zaś przy torsenie wystarczy lżejsza ingerencja.
Still....they are doing better than my e53 X5...
I think using track mode would be more interesting than drift mode. Because drift mode is designed to lose grip 😅🤔
These small cars are very obscure and not very popular in the United States. Makes for interesting viewing!
They are designed for tough fun 😉
These kind of videos are made for countries that do have them, although there were a little over 10k focus RS’s made for North American. Love my 2017 RS in nitrous blue.
Great video! I was also surprised to see the strugle of the Yaris with 1 wheel traction only. I am very curious how will the drivetrain of the 2007-2020 STIs compare to these two? What do you think @4x4 tests on rollers - duszaniespokojna channel?
Thanks! STI has very different awd system - there is center differential. I hope some day I'll find one for the test 🙂
STI awd is way better. Simple because is a true permanet awd. And not a fake one.
@@octaviangeorge5455 What is fake in GR Yaris and Focus RS?
@@4x4.tests.on.rollers gr have a clutch based awd, similar with the haldex. So it will not have a natural/instinctive/mechanical/predictable/etc feel and it will worn out in time. It will hit good numbers on track, dont get me wrong. But it will never feel fun and durable like an STI.
@@octaviangeorge5455 In such case majority of Subaru cars (non-sport) should be considered as fake awd to, right? And Nissan GTR to. But times changed, clutch based awd systems are amazing nowadays, especially when gearing trickery is used so car can be set to fwd, neutral or rwd characteristic.
18 RS has a limited slip front diff. But of course we have to use data from a 16-17 car.
Still nothing to beat my STI. 😕 I was really rooting for the Yaris but it's just not quite there. I drive it with WinterContacts in the winter and PS4Ss in the rest of the year. Have passed Audis reversing back down a snow covered hill 😁
You passed an Audi? 👏👏👏
I guess passed for both.
the guy in wrx sti : err peasant
You need to use a 2018 RS it has a mech front LSD.
not every one, only the editions.
@@f00lxplthere Is a special version? Could you tell me please ?
@@TANKSINATRA289 towards the end of RS production cycle there were blue edition, red edition and heritage. They were all equipped with front LSD unlike normal RS that only had clutch pack on the rear.
You also have to disconnect the sway bars so that the full weight of each corner can reach the ground.
I doubt thats an useful test, you won't be doing that to unstuck yourself in the middle of somewhere.
@@mantasv6208 It's a common non-real world, worse case test of the car's AWD system.
With off road tires Focus would've made the try with 1 free rear wheel ))
New street tyres would be enough. Or no white line under rear wheel.
No STI on the channel??
We need to see it!
Still no volunteers with STI...
@@4x4.tests.on.rollers Dang! One day :)
I am confused. If there is no electronic assistance in expert mode or esc off mode, how can gr Yaris pass the test with one front wheel and one rear wheel on the roller under these two modes? Shouldn’t the Torsen only act like an open diff since there is 0 resistance force for the wheels on the rollers?
There is never zero resistance. Even a wheel in the air needs quite a lot of Nm to spin. In this case two torsen diffs working together gives enough torque to the wheels with grip. Here's how torsen works in comparison with an open diff: ruclips.net/video/UlnGG4frZ68/видео.html
@@4x4.tests.on.rollers so theoretically speaking, if there is only one front wheel on the ground and the Yaris is in expert mode, increasing the other front wheel’s weight can increase the odds of passing the test? and using a torsen with higher tbr will also increase the odds of passing the test?
@@ralphw19 There must be an increase of weight on the slipping wheel, not on the other side. Higher TBR would help a lot but then handling/cornering would be much worse.
@@4x4.tests.on.rollers Yeah, by “the other front wheel” I mean the slipping front wheel. Thanks a lot!

0:18 Doesn't the Yaris use GT-FOUR, which has twin diffs on front axle, one acting as the central, the other as axle? It's been like that on the Celicas and a Corolla, and it was briliant, a full-time AWD in a transverse-engined car, did they change it? I was obsessing over it, if its not full time, this ruins the car for me :(
Nope, no center diff, here's detailed explanation of GR Yaris awd system: ruclips.net/video/PvXuryayDn4/видео.html
@@4x4.tests.on.rollers THE OLD GT-FOURS HAD ONE WHY CHANGE IT TOYOTA WHYYYY
@@kotelypiesely1268 Why not? It is full time awd which you can switch from fwd characteristic through neutral characteristic to rwd characteristic.
Gr all day!
I don't understand why toyota with 3 wheels on rollers is stucking without ESP when it have torsens rear and front?
Torsen ain't a locker. When three wheels are on rollers - one torsen is not enough to send enough torque to the wheel with grip. Here's simple explanation how torsen works: ruclips.net/video/UlnGG4frZ68/видео.html
@@4x4.tests.on.rollers Word, best way for people to think about it is that torsens are street diffs. If one wheel looses grip it won't spin the other, like if a tire is in the air or on a patch of ice, (or on rollers) which doesn't happen often on pavement. If a 4x4 or off road vehicle has an LSD it will be either a clutch/plate diff or manually lockable diff because those diffs do lock together. When driving off road you'll be in many situations where one tire might be off the ground, or stuck spinning in sand or mud, there you really need something that locks.
BTW, love what you do here on this channel. It would be cool to see you do a torsen vs plate diff test, might be hard to find two cars to compare though.
@@zachbrandt1236 Thanks. I will think about some compilation showing torsen vs plate diff, maybe some Audi vs Subaru. The problem will be TC/EDL which usually cannot be totally disengaged. And when it comes to torsen - two torsen diffs (TBR 2.3:1) in GR Yaris are able to move the car forward in side and diagonal tests.
@@4x4.tests.on.rollers Yes, it's a very tough test to find the optimal conditions for. You would almost need to find someone with a 2WD that was replacing their torsen for a plate diff. The EVO X vs Ralliart test you did showed the benefit of a plate, but that was over the computer controlled EVO diff.
@@zachbrandt1236 Speaking bout the Evo - the one from the test is equipped with rear plate diff now instead of original overspeeding one, soon we will compare the performance 🙂
is the Yaris GR the Track pack one that comes with the LSD diffs?
Front and rear torsen diffs.
What is the name of the roller device?
A roller 🙂
@@4x4.tests.on.rollers lol, what term can I websearch on? Or what company sells them?
When I search on Automotive and roller it comes up with items to help you slide a car around a shop or building. Not something that sits flat on a parking lot and has rollers that point upward 🤷
@@gteturbosupramk3 Unfortunately I don't know who sells them, I made mine by myself. A few years ago I saw them as free spinning roller, about 700 Euro for one pcs.
szkoda ze przy ostatnim tescie z tylnym kolem Focus stal na polbruku z biala linia a nie na asfalcie tak jak Yaris. Ciekawe czy by ruszyl?
Szkoda, nie zauważyliśmy tego podczas testu. Na pewno by ruszył 👍
Chciałbym zauważyć, ze asfalt jest bardziej przyczepny od kostki brukowej. Jeśli już robicie takie testy to warto by było zrobić w tym samym miejscu. Często się widzi w sieci filmy porównujące napędy 4wd np na śniegu i nikt nie zadaje pytania czy auta maja takie same zimówki. Zdarza się czesto, ze jeden wskazany faworyt jest na zimowkach, a reszta nie.
Testy robione są w różnych miastach, nie ma możliwości testowania w tym samym miejscu. Nie ma to wielkiego znaczenia, bo jeśli samochód kręci kołem z przyczepnością, to układ awd spełnia swoje zadanie.
@@4x4.tests.on.rollers W przypadku gdy trzy koła są na rolce a czwarte szuka przyczepności to chyba raczej ma znaczenie.
@@piotrmarciniak Mówiąc o kole z przyczepnością miałem na myśli koło, które nie jest na rolce.
very well but you're comparing tarmac road on the yaris with concrete paver blocks on the focus...
It makes difference only at 6:35 and 12:25, mainly due to paint.
Why use the drift mode ?? Use the sport mode it will be even better. My 2018 rs have a front torsen diff best of both world 😁

Why did the GR Yaris only struggle with one wheel when it was in expert or all of mode?
No help from electronics then.
@@4x4.tests.on.rollers strange that it would need it ?! Must be something about the torsen diffs?
@@MT-eb2dx It would be strange if it wouldn't need it. Torsen diff itself is not able to overcome such situation, it needs help from braking system.
@@4x4.tests.on.rollers Hi. My understanding, from numerous reviewers around the world, is that the GR Yaris' esc is very competent but, arguably, a little intrusive with regards to the 2 torsen lsd's in the circuit pack.
It's only when esc is in expert mode or fully off that the reactive torsen lsd's activate, and when they do, you can hear an initial wheelslip first, likely due to their 2,3:1 tbr.
That explains why esc intervenes first unless it's disabled!
@@James-RJM I'm not sure what you mean. Torsens work all the time, accelerating, decelerating, cornering. On throttle, ESC intervention increases torsen operation.
Ford for the win 🤟🏼

The Focus looks well programmed but I am amazed by the composure and elegance of the Yaris GR.
I just wish Toyota had made its own Supra rather than handing the task to BMW.
I kinda wished that Supra was like Yaris+3 more cyl
Focus has a very stiff chassis, which is why it failed the last test.
It didn't fail, it was just missing grip.
@@4x4.tests.on.rollers do you mean it's weight distribution is to the front, so the rear couldn't get big enough normal force on the tire that is on the ground?
@@isleofauto Main problem were tyres and white paint (line) under rear wheel. But more normal force (like passenger at the back) would also help.
@@4x4.tests.on.rollers Yeah true it couldn't put enough weight on the tyre because the chassis wasn't flexing.

Both cars 4wd system has enough capability to clear this kind of trial, but Focus has much better coupling system.
But in the situation of threee wheels lost traction like that, the weight is much more important, that's why Yaris showed bit better performance at that test....
So the Ford was best ? Still buying a gr ? I don’t know , needed commentary . Somebody say something! I understand but , that was hard work.
Hear me out have you tried not doing a full send instead of just slowly engaging food for thought lol
