    The slip is happening on the diagonal because the chassis and suspension are stiff and the two wheels touching the ground have less load (less articulation). This AWD system is crazy good ( low reaction time, passed all tests), better than most crossovers it seems.

    I think what often goes unmentioned here by reviewers of the GR Corolla's AWD system is that when you "lock in" a drive mode, it doesn't actually mean you are always getting that exact torque split at all times. This is to say, it's still going to favor FWD, but will give you UP TO 50-50 (when in track mode) in certain situations. Or it will give you UP TO 30-70 splits, say in cornering or icy/loose roads, but when the wheels straighten out and you're driving down the roads, it's primarily an FWD vehicle still. I think Engineering Explained breaks it down in some detail. But I think this slip test illustrates that you aren't getting 50-50 or 30-70 even though you put it in "track mode." You actually got MORE front wheel slip in those two modes than 60-40. You should have gotten less.

    I've got a GRC with the LSDs, and I'm happy TFL conducted this test. In track driving, I can affirm that I can feel the torsen diffs aggressively push power to the outside wheels. Not as aggressive as the clutch pack eLSD on my old Veloster N, however. 50/50 Track mode is the fastest and easiest to drive, IMO. Followed by 60/40, and lastly 30/70. It still has the weight distribution of a FWD car, so driving it on the limit in 30/70 means that the car isn't getting the power down effectively since the rear is so light compared to the front. I just drive mine in 50/50 all the time now. The GRC looks to be super effective in the snow and inclement conditions. I'll just put on Michelin CrossClimate 2s and never have to worry about road conditions. I'm impressed at how simple and lightweight Toyota made this AWD system. And even more impressed at how effective it really is in the real world.

    These rollers are tougher than actual near zero friction like say wet ice. You really need a decent amount of torque especially in the 3 wheel test because you have to push the other 3 wheels up and over the roller. Not having the hole between rollers would be closer to real world. This is like 3 tires stuck in potholes made of slick ice, where they are raised.
    Pretty sure even with open diffs this car would smash winter weather, those are really more track focused imho. I had a manual Avant for 15 Canadian winters, Torsen center diff and open front and rear with just traction control helping out and there was nothing it couldn't go through, sure footed even on packed snow roads. This would be even better.

    The opposite wheel test (~10:00) it spins because it's so stiff. If you raised the non roller wheels it would pull right off.. this is the only 'bad side' of a stiff chassis.

  • @PatrickRich
    @PatrickRich Рік тому +13

    I think with the way this AWD system creates this torque splits that you won't see a lot of difference on a slip test. You get a rear bias by means of a rear differential ratio that is slightly overgeared compared to the front, which means you need to slip the clutch all the time but it also means you need to be moving fast enough that the small gearing difference in the rear axle can be a factor in creating a torque imbalance. In other words you don't get a rear bias until the rear can "push" the front. From a stop you aren't going to get enough windup for that to happen and even the minimal clamping load on the rear drive module you have more than you need to get off the rollers without winding up the drivetrain.

    In some of those tests, the weight available to the tires on the ground is what makes this harder. This was much worse case than the normal limited traction conditions that will be faced.
    Also, based on other info on the GR, the torque split is the limit with the system being FWD biased and sending torque back as needed up to the set limit.

  • @wild_lee_coyote
    @wild_lee_coyote Рік тому +1

    The way the AWD works for the Corolla is there is a electronic clutch in the rear diff that controls the torque split from the front to the rear. There is no center diff. This means it is still front biased which you can see in the difference in wheel spin in front to rear split tests. It also means that the rear diff, with the clutch, can be prone to overheating. This will force the car into FWD mode. But overall the AWD is pretty impressive for a car that doesn’t have center diff and is not showing any braking for torque transfer.

  • @chapystick_

    Explanation of how this AWD system works:
    The front differential is the final drive of the transmission. If your transmission is in gear and the clutch is out, the front diff will always spin and has a direct link to the transmission with no slipping in between.
    The driveshaft to the rear wheels is also directly linked to the front differential and is redirected 90° through the transfer case with again, no point of slippage.
    The rear differential is where everything happens. At the input shaft, there is an electronically controlled magnetic wet clutch pack that varies its clamping force to allow the rear wheels to spin only up to however fast the front differential is since the rear driveshaft is physically linked to it.
    The only special difference about this drivetrain that allows a “30F/70R” TORQUE split is that the rear axle is geared to spin 0.7% faster than front axle, even though it’s literally being rotated by the front axle.
    Fun fact of the day: Among likely many other vehicles, one notable car that’s used this system is the 2005-2007 Mazdaspeed6, although the difference in rear axle speed was only 0.09% faster

    Looking at the video of the diagonal slip test makes it seem like the test is actually disfavourable for lowered cars with stiffer suspensions/sway bars. The thickness of the roller platforms combined with the stiff sway bars seem to be lowering the contact pressure of the opposite corners that are supposed to be on the ground reducing traction. It's like when I jack up a corner on my car that has an aftermmarket sway bar, both sides of the same "axle" lift for a bit because the sway bar is supporting both sides. I bet that if you had a static platform, like a slab of concrete, under the wheels that are not on rollers to keep both ends leveled, it might change the result and make the car roll off sooner in some tests like this GR Corolla. Not as big of a deal on crossovers and SUVs with lots of suspension travel though.

    From what I've seen, it's like they said with this AWD system, front wheel bias. That is why the front wheels are always spinning immediately. Only when the system picks up the slip from the front is when it sends the power to the back. That LSD and 30/70 did help it a lot at the end. I am surprised how responsive the AWD is! Additionally, we have to understand the over heating issue with the system which will cause it to go into FWD only.

    I think what may clarify the 60/40, 50/50, 30/70 is that these numbers are assuming a normal dry road, going straight. How the system works is that you have a FWD car, period, it's FWD, but then it has a PTO to the rear diff which has an advanced multi-plate wet clutch. The rear diff is geared such that as you connect the rear through that clutch the rear wheels begin to overdrive compared to the front, unloading the front tires, and thus taking a bigger torque load. You can kinda see this on the rear wheels stuck test, there's a tiiiiny bit of procession on the rear wheels vs the front. Now once you're in snow or trying to drift, unlike a car with a true center diff like older BMWs or Subaru STIs, Evos, this car once that rear diff is locked, there's only a tiny bit of procession. So you can't crank up the wheel speed and get a big huge slide. Where with an STI, if that center diff is open it's rear biased and it'll overdrive the rear tires significantly.

    It’s a car… so the difference we are seeing in the bias I am almost convinced is purely weight based. What’s the weight split? Heavy front end will totally make the test work exaclty like you see it. Perhaps try it in reverse?

    Some basic explanation on awd systems and how diiffs work so you can better understand the gr corollla awd system and its weaknesses it has, for anyone who might be intrested. Im an engineering student so dont take my word for it, this how i undrestand it. (it may contain spelling or grammar mistakes, english is not my native languge and i hadnt had writing practice in a while.)
    torsen diifs and all atb diffs like wavetruck torsen quaife diffs dont lock, they cannot lock on their own. That menas they cannot forse both tyres to rotate with the same speed, they are not speed sensitive, they are torque sensitive. Tha means they wiil force torque to they wheel with most traction by trying to "lock", as long as at least one wheel has traction. They al have small lock percentage, depending on the diff. So if one wheel has no traction, they cannot tranfer torque. In order to get unstuck, torque vectoring via braking must occur so that that the spinning wheel gets some resistance(load). And that the drawback of a torsen type. Then whats the difference from an open diff in that case. The difference is that much less braking must occur for the car to move so less brake wear. Plus the times when one wheel has zero trction are not so often. Wavetruck has a pattern where the diff gets preloaded with springs so it has higher lock percentage and it can operate even if one wheel has close to zero traction, on paper at least. The benefit of these diffs is that there are cheaper to buy and maintain and they dont wear oyt as easily. In contrast, a clutch type diff has much higher lock percentage and ots speed sencitive so it reacts to speed difference not traction difference. That diff willmtry to lock the wheels even more and will almost have them rotate with the same speed. However since it reliess o traction between clutch plates, the diffs need regular maintance and they cannot take s much load. There are two types of clutch type diffs, electronically controlled or torque vectoring diffs(with are different from torque vectroring via braking) and mechanically controlled. Both are mechanical diifs, what changes is the way the engage and the ammount of control you have over their operation. e-clutch diffs are more adaptive and they are predictive, meaning the cars traction control locks them before they need to be locked based on the driving situation where as the other are reactive meaning they react after loss of traction has already occur. Different drivers will prefer either one or the other and most times they will reject any different opinions lol, specially purists. Another drawback of the mechanical clutch type diff is that its noisy and obtrusive in everyday driving as you cannot control its locking function. Thst can be very annoying in tight slow speed manuvers like parking where the diff is locking due to great speed difference thus making manuvers difficult(unless you park by drifting your car haha). An e diff wont lock in that situation since its actuated using eletric motors controlled by the cars ecu. A tosen wouldnt lock either since as we said, its traction sensitive and not speed sensitive. A true locking differential can be any of the diffs above(open , torsen, clutch type) but with the ability to fully locked with a use of a lock ring. For example wrangler rubicons used to have a torsen read diff which could be aslo locked so being the best of both worlds. The gr corollas awd system disadvantage though lies on its center diff. While it says it has three different lock percentages, it doesnt actually lock, it does not stay locked. It uses a clutch type center diff like a haldex unit with the difference beign that the driver can manually choose the torque split, but it splits torque and it does not affect wheel speed difference between axles, much like a haldex would do automatically or much like a quattro systme with a trosen center differential would do. Thats important cause if you are to use the gr corolla for ralling or track use, after a few laps, the clutches on the cenetr diff will overheat and the diff will disengadge rendering the car FWD. Thats because the center diff is not meant to hold the selected split all the time(as i said it doesnt lock) but rather to only engage when needed. So in a case where it would need to stay "locked" all the time like in driving on a track or a dirt road for fun, the diff woud overheat unlike a torsen in an audi which is meant to have awd engaged all the time. However, toyotas decision to use torsen diffs instead of clutch type diffs, was very clever as they are more reliable and cheaper to maintain na deasier t live with in day to day driving(which is what toyota owners want) and even if you were to actually go rallying with your gr, zero traction situations would be almost zero and the torsen diff combined with the traction control system, would do just fine. desides, a rally driver is more concerned about smooth torque tranfer that can be achieved with torsen diffs than unlimited slow speed traction like in a rockcrawling situation(or that what i guess anyways).
    My analysis is not perfect and maybe in complete so if someone has question i will try aswer them. For better visualisation you can visit engineering explained and weber univercity channels vids about diffs.

    You guys should put in a drag strip and make an area with long strips of rollers strategically placed whereby you could do the slip tests on cars with various wheelbases. Or make them in such a way that they can be covered for testing/protection but also facilitate plowing snow and whatnot. Great video though! Interesting to see how that AWD system performed! That car is a total beast!
