SLIP TEST - Nissan Qashqai All Mode 4x4 vs Hyundai Tucson 4WD -

[@Softroader]

There's a lot of interesting stuff on this video. You can see that the ITM3 mounted on the Tucson works quite well, but there is a bigger difference between the "auto" and "lock" mode. You can also see that the traction control on the Tucson is quite functional and more progressive, although it is totally dependent on the ESP. We can also see that its power seems to be fixed and distributed between the 2 axles because with only 1 wheel, even at the front, it is not enough. On the other hand, we can see that the Quashqai's clutch deactivates quite well when a rear wheel is alone to drive.

Interesting thing is that rear axle is spinning even when no current is applied. Of course the axle is already speeded up before but the clutch-pack itself is able to keep some low torque.

[@Softroader]

@@4x4.tests.on.rollers Yes, but if the solenoid is not under tension, there is a minimum amount of torque that passes. Internal friction? Mechanical system that creates minimum pressure on the multi-plate clutch? But that doesn't surprise me more than that. In this kind of system, it's never mechanically 100% locked or 100% free. Another thing, from the moment when the solenoid activity is zero, the vehicle does not move anymore. It seems that the traction control is totally inactive (which makes sense). Whereas on the Tucson, it always feels like the whole system is trying.

@@Softroader From my observations - if no current is applied to the electromagnetic coupling than it is almost entirely open - torque is minimal, rear wheels barely spin: kzbin.info/www/bejne/gmnOiaWFqKeSh8k But - as we see on Qashqai - when wheels are already at some speed, it is tight enough to keep them spinning. Traction control - yeap, very different setup for these cars.

[@Softroader]

@@4x4.tests.on.rollers Hence my question about whether there is a mechanical system (or internal adjustment) that maintains a slight pressure on the clutch. I would need to find the internal schematics of the Nissan system.

@@Softroader That's EMCD by GKN Driveline.

Fiat freemont test?

Странно что у ниссана в неудачных попытках на соленоиде А ( подключения полного привода?) ток ноль, а задние колеса вертятся.

[@4x4.tests.on.rollers]

That's probably due to some internal friction. They are spinning but with barely no torque I believe.

Why is there no MAXIECU live data on the Hyundai?

[@4x4.tests.on.rollers]

There's no data from 4WD controller.

[@BledaTurk]

who beat it?

[@Rich_123]

Does the Tucson have a mismatched tire size in the rear?

[@4x4.tests.on.rollers]

Why do you think so?

[@Rich_123]

@@4x4.tests.on.rollers rear tire looks taller. Might just be dirtier?

[@4x4.tests.on.rollers]

@@Rich_123 Yea, probably. They are the same for sure.

Widać, że w Tusconie ESP jak jest wyłączone to razem z EDS

[@4x4.tests.on.rollers]

Dokładnie tak.
