Quattro ULTRA or TORSEN? Audi A4 Allroad vs Audi A5 Sportback - 4x4 test on rollers 

A5 2.0 TFSI 2017 is imposible torsen, only quattro ultra.

I like the old torsen.

I like how this channel progresses in understanding and explaining the technology used and tested.

Excellent demonstration. Let's remember the difference. Other is purely mechanical and other is an electronically driven clutch pack. There is no question about it, the mechanical torsen will always be more reliable. Because it is analog. It will never fail.

Great job with the new English comments and explanations ! 🤟

Old Torsen, the best!!

Fantastic channel! Love the narrator with extra info!

Duszaniespokojna 🤔 Super materiał !

Robicie świetną robotę

After watching all your videos, and many off road ones I came to the conclusion that the ''Torsen'' ''Ultra'' ''Haldex'' mean nothing since 2 vehicles can have the same platform and same AWD like ( Q3 vs Tiguan) and one would work well off road and the other would suck, similarly the Ultra system on Q5 seems far better than the one on the A4 Allroad, it all depends on the way traction control/AWD is programmed by the manufacturer some AWD are designed for spirited driving and performance while others for traction and safety.

thanks for creating the video with english explanation =) i just purchased an used 2018 Audi a4 Allroad to replace my 2011 A4 Quattro 6 speed. going to miss the manual transmission and Torsen technology but hello Quattro Ultra =)

Very good lesson.

это шедевр!

Çok güzel bir test olmuş elinize sağlık 🙏🎉

I wonder if it be possible to have little footnote in one of the corners, saying what car & spec is on show? Love the education at the beginning 👍.

Both drive variants work. The real difference can be found on the front axle. The electrical differential lock (EDL) is programmed differently. Adapted to the respective drive or its philosophy. With Ultra Quattro, the control unit actively transfers power backwards first time, the EDL on the front axle remains passive - it only reacts later. The video show this perfectly. With the Torsen Quattro it is known that the torque is distributed with a response time of 0ms between front and rear. Here the EDL on the front axle can react earlier, which is an advantage over the Ultra Quattro when only one wheel has grip there. But this is only a time advantage. I think that in real life it won't have that extreme an impact. What you notice is the difference in the response time between Ultra and Torsen, the Torsen looks calmer overall. I have two current A4: one with Ultra and the other with Torsen.

Good job man Awesome channel keep up good work Torsen on F150 works like lucking def not much wheel spin but on audi its let the wheel spin lot longer

Polska!

Oglądając to porównanie naszła mnie refleksja, że niewątpliwie oba rozwiązania mają swoje plusy i minusy. Miałem kiedyś Torsen-a, inteligentne sprzęgło mam teraz. Podobnie jak inni użytkownicy, którzy jeździli starszymi Subaru, a potem przesiedli się do SAWD na sprzęgle, narzekali głównie, że jak rusza się z miejsca przy skręconych kołach wyraźnie czuć poślizg osi przedniej, nim tył się na dobre zblokuje. Taka sytuacja nie dotyczy napędów, gdzie dołącza się przód. Nie było też tego w centralnym dyferencjale, a tym bardziej w Torsenie. Fajnie było by dołożyć do Twoich testów próbę gdzie przednia oś jest na rolkach, ale na maksymalnie skręconych kołach.

But hey u can't throw a 4 mins of video which covers every aspect. It's not American style! Where is drama, meaningless talking, advertisements.... :) Thank you for video

Witam Panowie, świetna robota na kanale. Poczytałem komentarze o A5 2.0 TFSI. Dla pewności. A5 2.0 TFSI 252 KM S-Tronic rejestrowane po raz pierwszy 01/2017 to Torsen, zgadza się?

Torsen Quattro are only in longitudinal mounted Audis, and they’re always mechanically locked to the rear. Haldex “Quattro” is in transverse mounted Audis and is fwd until the fronts slip. My b5s4 is gen 4 torsen awd (meaning it has torsen center diff) and is always on awd.

Torsen the best 👍👍

Что и требовалось доказать: старый добрый механический Торсен рулит! И как покажет себя надежность системы спустя 200 тысяч километров?

Hi, does the Quattro ultra work as FWD at highhway speeds? Just like Haldex? (If i remember correctly after a certain speed the Haldex 5 is working as FWD)

Hello, I have the Audi A4 B9 Avant 2018 Quattro, but it does not say it is ULTRA (most probably not as it does not mention it on the decription) does it mean it is Torsen ? Thanks!

Ahh, komentarz w lingłydżu! ;-)) Tak czy owak - do Karpacza wolałbym wjeżdżać po śniegu samochodem z Torsenem. Testy na rolkach są... wiecie ;-) Dla wyświetleń :P

let's see it

One thing rollers can explain is the feeling on the road. Because quattro ultra is front bias and torsen is rear bias is a big difference. You can drift more easy and also if you get stuck in an incline fore example the fact that in quattro torsen it has a slip all 4 wheels will help you get move in big snow for example. And with the quattro ultra you wouldn’t move in extreme condition!

Ultra 👌

My b7 s4 avant is a beast in this tahoe snow. Strait up driftn. Naw but it does good im hapoy with the system. Rain or snow im very confident

Which one is better and why?

I have a 2018 A5 (like the black one here) with the torsen system. I wonder what the reasoning is for having the delay before all wheels are engaged at launch? Also I wonder if a rear-wheel bias with the front wheels engaging when needed would be better? Launching off front wheels seems illogical? But when you floor it off the start there is great traction, even in the wet and with the traction control off

👍

a nowa a5 nie ma czasem juz haldexa? poprzednia na 100% miala torsen ale przy tej nie dam sobie reki uciac

Дело даже не в то съедет или нет, а сколько проживет муфта при активном пробуксовывании а торсен это чистая механика ее не перегреть только сломать. И да спойлер интересное в конце.

What are those wheels? stock?

Does a 2009 Audi A4 2.0t prestige have the ultra?

I hope to see soon Quattro with Sport differential :)

Old Quattro's from 1980 had NO center differential. Not even an open one. They had a fixed connection to both axles still. That made the rear axle become bumpy. It was not possible to use the hand brake to take hairpin turns. On the other hand at that time in the turing cars sports they had no ani-lock braking system, but because of that fixed connection between both axles they were able to brake very late and hard into a corner. If you don't believe it just ask Walter Röhrl or Hans-Joachim Stuck. :-)

Torsen!!

Hi! From where I can buy those rollers, I want to try these tests with my friends, we all have Audi and we are curious? Thank you!

Kupiłem nowe audi a5 40tfsi quattro rocznik 2021. Jaki napęd posiadam?

Jesli chodzi o taką A5 2,0 tfsi 252 km, to zawsze byl torsen? Ma znaczenie EU lub US?

hi, 2018 6speed manual a4,can u please tell me is it haldex or torsen?

So the new quattro (ultra) is not 4x4 anymore? Its closer to bmw xDrive just opposite since bmw has constant torque to the rear and when need engages and disengages front wheels

Zaskakujący wynik... Nie spodziewałem się

Не тот автомобиль был назван «все дороги» А5 шикарна просто отработала «вывешивание» трез колес

Both are good but the Torsen wins it for me.

To który jest lepszy bo nie widzę roznicy?

Audi 100 win test :)

I LOVE TORSEN

Is it weak at idle? Or at least at low revs?

I have old Quattro with center and rear diff lock😎

So which performed better in the test then. looked exactly the same, who won?

Co Torsen to Torsen stary ciężki mechaniczny skuteczny układ napędowy 👍

Which of the two has my 3.0 TDI 4F FL?

Hello guys Im south korean, first i apologize to you because my english is shit and i hope you understand my reply i bought a5 40tfsi quattro 2021 7th stronic I wonder the ultra system is based rear? Or front? And ultra's default drive wheel is awd?

Интересно было бы увидить а6 и рс6

Is it possible that you make a test wie a VW T6 4motion vs Mercedes V Class 4matic? It would be very interesting because there is 1 Video on RU-vid on Ice and this Video is not so serious like yours.

Audi a5,2.0 tfsi[f5] Up 2017 ist ultra or Torsen)?? Thank you.

Какой вывод то ? Ничего не понял))

Honestly a bit of a toss whether one is better than the other. I used to believe a mechanical system like Torsen is better than Haldex or quattro Ultra but the difference is so minute it honestly is kind of a toss for standing start. In performance driving that might be a different story however.

Quattro ultra easy dirft when wet put in sport mode, feel strange, i tried few times.

A6 2016 2.0 tdi quatrro have? Ultra or torsen?

все-таки торпеде как-то мягче срабатывает. электроника не всегда корректно и адекватно себя ведет. железо более предсказуемо себя ведет.

Whre csn i buy them rollers ???

Diff lock anyone?

So they’re both good?

Is the new 2021 a5 still Torsen Or it's using the Quattro ultra?

Do the old TT vs new TT

Torsen ist beste aber gibt,s ab 3.0 Motorisierungen denke ich

Что лучше ? Old torsen?

Torsen 👍

Ok but how does the clutch pack work? Is it only for the rear and the front is permanently connected? Also it’s important how the esc works because if the wheel that spins isn’t slowed down by brakes there will be minimum torque available for the other wheel even if the torque available on the axle is good.

С четырех сможет?

End who winn?

Поставьте туда audi 100 44))) Quattro

Quattro ultra is the result of eu regulations. Thumbs up for the good old torsen.

Does the rs models have torsen or ultra?

Therefore this ultra works more or less like BMW Xdrive but it's front biased instead of rear biased system

when did the B9s switch to ultra ? Because I own an A4 B9 Allroad from April 2017, 2.0 TDI manual, I’m from Belgium but I don’t know if I have a Torsen or an ultra (haldex)…

Old torsen is the best

2way mechanical lsd

Why did this car with the torsen center diff work “better” then the other older Audi’s with torsen center diffs? Older cars were not able to get off the rollers when either both front or backs were on the rollers.

Mechanical vs electronics

Жалко что ауди уходит от классического полного привода quattro и взамен ставит дешевую и капризную муфту халдекс(quattro ultra)

Quattro ultra is an excellent System. Just enjoy it😊

I have a Touareg with old Torsen

CH Janki ?

A litlle sugestion... as i watched it, i had to look closer and pay attention what audi is what. For me was better if it was written for every test under the car witch traction was ultra and witch was torsen

Torsen Power

Or as in my case with the SQ5 it has the torsen PLUS rear sport lock diff I'd think would be the best.

Obviously Torsen won the game!

In your opinion is Quattro Ultra worth the extra price over FWD? To me it seems everyone loves to bash Ultra. (Asking to the 4x4 test on rollers :))

Torsen

Only torsen, no electronics

Every 4wd system except Quattro and Subaru’s symmetrical need maintenance, Haldex being the worst with close intervals and costly

CH Janki? ;)

Бред, так нельзя сравнивать! 1. Машины разной массы. 2. На машинах разная резина как по ширине так и по высоте. 3. диаметр самого колеса тоже разный. 4. на какой машине какая коробка передач. А в целом как показывает практика торсен и ультра простые тесты проходят одинаково. Ультра лучше в нестандартных условиях проявляет себя. Но торсен более прогнозируем с точки зрения управления.
