SLIP TEST - HALDEX 4 vs HALDEX 5 - Volvo XC60 D4 D5 AWD -

[@leetshots]

It seems the biggest difference between various on demand AWD systems seems to be the software controlling them. Which seems to change not only with each manufacturer but also on each model and generation.

[@jpch8814]

Awesome AWD system and very underrated ! It is used by Volvo,Volkswagen,Skoda,Seat and some Audi.

[@swine_tech8014]

The performance of the AWD system is practically the same, the newer X60 performs probably slightly "softer" than the previous model. I think the most differences are in the SW of the ESP module and not the Haldex, which possibly got only minor improvements.

Very cool haldex 5 simplified the pump so there’s no longer a filter great how they got away with more hardware by improving the electronics

[@TsLeng]

Still need to clean the internal mesh otherwise high risk of failure. All things equal, it is almost certainly going to fail earlier if not cleaned vs cleaned

[@jerryl6634]

No big difference. Actually I don't see any.

[@4x4.tests.on.rollers]

Final result is the same. The only difference I see is that gen 5 is more open in off-throttle position.

[@saiiiiiii1]

According to Haldex version 5 is lighter and easier to integrate.

[@RTI_MD]

@@saiiiiiii1 Means cheaper and less reliable, also has no filter there...

[@jed2i]

​@@RTI_MD it requiers that you change the oil more often. Then there is no difference in reliability

Great job, thank you for this video! I saw no difference between the two gen.... but I understood that I must turn off ESP in case I'm stuck somewhere, lolololol

[@4x4.tests.on.rollers]

Gen 4th seems to engaded right from the start, gen 5th seems to be engaged on-throttle.

[@myslecinaczej8674]

The software can do magic. Search this channel and see that Gen 5 as implemented on different Volvos behaved differently. The V60 CC (gen 1) was just better. And the V60 CC recent gen. id really excellent (that one I seen somewhere else). On the other hand the eAWD from Volvo, installed on most expensive T8 versions, plug-in hybrid, is a week system.

Pretty interesting that it works better with ESP off while other AWD systems work better with ESP on.

[@connorPiper0]

Volvo cars have "spin control" toggle, the DSTC system cannot be disabled in any P3 car. But you can allow the car to disable the low-speed traction control and prevent the throttle from cutting out wheel the wheels are slipping.

[@4x4.tests.on.rollers]

@@connorPiper0 You can disable DSTC (ESP) but traction control (brake intervention on slipping wheels) remains active, only engine torque ain't cut like with DSTC on.

[@connorPiper0]

​@@4x4.tests.on.rollers In Volvo's own words, "The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is accelerating" "[Traction Control] is designed to help reduce wheel spin by transferring power from a drive wheel that begins to lose traction to the wheel on the opposite side of the vehicle. This is one of DSTC's permanent functions and cannot be switched off" So what most automakers call traction control, Volvo calls it spin control. Traction control is a function of the AWD system. The high speed traction control is called AYC. You absolutely cannot disable DSTC in any P3 Volvo car without the help of VIDA DiCE and even then it's not easy. The gauge cluster even makes sure to tell you DSTC is on still. I own several P3 cars currently.

[@4x4.tests.on.rollers]

@@connorPiper0 The definition of Traction Control which you quoted is actually the most popular. Spin Control used to be called ASR by many manufacturers. When it comes to DSTC - screen in the car says it is off. For sure it is not entirely off, just backed up a little, that's standard behaviour in many cars nowadays. DSTC includes SC, TC and AYC. The last one in Volvo is actually a ESP system (braking wheels to correct lateral slides).

[@connorPiper0]

@@4x4.tests.on.rollers At least in the NA market traction control and stability control were separate options on many vehicles, stability control would prevent over-correction leading to rollover which was a popular option on many SUVs and trucks. Basically there are two ways to control the vehicle, with brakes or throttle. Spin control is throttle related, and the only system you can disable. Every other function of DSTC uses the brakes, and cannot be disabled. Volvo calls most of these systems part of traction control, same with Toyota and A-Trac. German automakers might call all this ESP. To correct understeer the Volvo system and a majority of American cars use the throttle, or the traction control system. While to correct oversteer they would use the brakes, or the stability control/ABS system.

[@the_dovla]

I swiped my OEM speedometer on my 2010 XC60 for newer TFT and after that I haven't option do disable DSTC. Am I fucked up on the ice and snow now?

[@jovandjukic5923]

I think H5 has little bit more spining then H4? Are we see same? What do you think?

[@4x4.tests.on.rollers]

I see H5 is open in off-throttle position, H4 is at least partly locked.

[@Vamanos46]

@@4x4.tests.on.rollers ...Can you think of any small advantage / disadvantage in any specific scenario in which the partial locking at off throttle would make a difference ? Nothing?

[@4x4.tests.on.rollers]

@@Vamanos46 It is all about response time. I don't know the numbers but imagine that during start computer sends request for 60/40 split. Haldex 4 needs for example 300 miliseconds to switch from open to 60/40, Haldex 5 needs for example 100 miliseconds to switch from open to 60/40. However, if you keep initial (off throttle) split on for example 80/20 level then Haldex 4 may also reach 60/40 in 100 miliseconds.

[@lakshmandalpadado9066]

Actually the H4 is better than H5. The H5 lacks the oil filter, and as a result , oil residue gums up the oil pump.

[@godgirlsguitars]

Honestly I feel the reason why they made it off the three rollers wasn't because the rear wheel got enough torque but because the front wheels went forward just enough to catch the front lip of the roller and launched it off. What do you think it felt like when you were driving these cars and what does it look like in the video to you?

[@4x4.tests.on.rollers]

If front wheels went forward - it means that car was moving forward. Furthermore - wheel can touch front lip of the roller only when car is already going down. Up to that point car must climb up only on rolling cylinders (to be precise - on one cylinder per wheel).

[@Castelele]

Nice and interesting! And hopefully both cars have the 5 cylindre!

Excellent improvement, only name changed Haldex 4 to 5. Torsen is the best!!!

Torsen ain't doing better in such cases. When it comes to improvments - that's 2700 Nm vs 3500 Nm, less weight, more precise control.

[@4x4.tests.on.rollers]

​@@RealAutoReviews It won't be better cause it doesn't have the ability to lock the axles together. Haldex can do it but only temporarily so in long offroading it would overheat but in single situation it's effective.
