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.
Mam powody do świętowania 👍 Obie generacje poradziły sobie bardzo dobrze jednak gen5 trochę lepiej. Dzięki za porównanie i idę po kolejnego szampana😂 Pozdro dla Ciebie i innych użytkowników XC60
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.
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
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.
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
Have you had the chance to do a test of the Saab 93 xwd? It's got the same Haldex 4 system but with an eLSD on the rear and I was wondering if that fixes the problem that these Volvos have with the one rear wheel refusing to recieve power.
Thank you for the great chanel! I was wondering if it would be possible to see how a Skoda Kodiaq fares against the rivals like Kia Sorento, Huynday Santa Fe, Nissan Xtrail?
@@trainslife5638 This D4 is a detuned version of the d5. Same engine, different software. The fwd D4 is a 4 cylinder of the new generation called VEA. But awd diesel have remained with the previous generation 5 cylinder until model year 2017 (included).
I didn´t see actually no any difference? Is there? Maybe in snow in real condicions? What about if there is a software "offroad" option as nowadays in many Volvo AWD systems?
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.
@@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.
@@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.
@@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).
@@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.
@@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?
@@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.
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?
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).
The filer is internal on the pump itself. It gets clogged eventually so cleaning is recommended. Only problem is, that isn't part of the official maintenance scope if done by dealers Pretty shameful really like you said, for most it will be more unreliable
@@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.
Silloin kun kolme pyörää on rullilla ja takana ainoa vetävä pyörä niin haldex tarvii kaasua reippaasti niin lähtee kyllä irti. Tässä videossa kierrokset jäi liian alas joten auto ei lähtenyt liikkeelle kun vasta lopussa.
During slippage throttle is controlled by the system. Here's another Volvo, no problems at low throttle in offroad mode: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jld57N9Ramw.html
Hey duszaniespokojna! I had a thought - if you can help me build rollers, I would happily send you video footage as closely modeled after yours for my cars! I have an Acura TLX SH-AWD, and Mercedes ML430, free to use if you are interested!
@@4x4.tests.on.rollers Makes sense, that is too bad! If anything changes please mention in your videos and I will comment again :) Thanks for the awesome channel!
Обрати внимание, что по звуку мотора на 2014 года муфте нужно было больше газа. Так же можно сделать вывод, что если не можешь куда то забраться в гору, то надо ехать задним ходом, так на передние колеса "мощнее".
It is always funny in wintertime to launch from traffic lights like it was summer. Since Haldex is front biased, and the nose is slightly heavier I always win against four wheel drive mercs and bmws.
