Interesting design and concept. I also understand you can keep in AWD too, (button selection). Over time, I this will help in owners fuel costs. Time will tell if there are any issues regarding as Quattro itself is bulletproof.
If i am not mistaken audi has retained the center diff that splits power from front to rear this is just added clutches that make it fwd by uncoupling the rear driveshaft when not "needed". When the car is in sport or the esc off the awd stays on always as usual with constantly varying torque being shifted front and rear as needed. Audi changed the center diff many years ago but it still acts like a torsen.
There is no centre diff when you have a system with clutches. It's not needed, this system puts power from the transmission to the front wheels, with the clutches engaging to tap power to the rear wheels when needed.
@@ralex3531 it shows you the clutch pack engaging and disengaging the rear axle. There is no centre diff in that video. It's not required when clutch packs are used. You can't send power just to the rear wheels as the front always have power the transfer case can just vary the power to the rear.
This system sholud not be called "Quattro Ultra", thats deceptive. It provides less AWD performance than classic quattro, only a bit higher efficiency.
Shame on you Audi! You gave up the best thing you had - permanent Quattro AWD. Quattro ultra is better than most common classical AWD with Haldex clutch, but it can't compete with permanent AWD system lika old Quattro. I'm disappointed...
Too complicated system. Clutch disks must be durable due to hight engine (diesel) torque and small diameter . Good for every day driving and for snowed roads but in mud terrain or offroad a lot of things may be falling apart
Audi lost patent rights to use Torsen, patent expired so Audi had to come with their own drive system. As you can see, it is really extremely complicated. Audi did not invent Torsen, they bought rights to use it and in 2008,. (I belive) they lost rights.
All these fancy AWD tech that could fail and yet subaru can match it with just a simple open diff and braking the other wheel effectively to provide traction to the other wheel.
Después de ver como VW, BMW en un documental sobre la trampa que hacían para encubrir las emisiones con los motores TDI , ahora le tengo mis reservas a los autos de Lujo, ahora mi opinión es que te venden marca nada mas y solo te enseñan lo que siempre han tenido los autos normales como el toyota, nissan , mazda, kia etc etc , y a menor precio al único que que si creo que hace bien su trabajo y por eso es caro es el VOLVO, de los autos de Lujo. los demás ahora los miro diferente, y según miro en este vídeo eso ta lo tienen todos los autos incorporado si el auto es tracción en las 4 ruedas.
I don't trust Audi's Quattro tech. They just over advertising for people and they are reusing old mechanism. They should develop electric+program logic on Quattro.
so hang on, it looks to me like when the dog clutch engages at the back, the rear diff is effectively locked, the left and right cannot spin at different rates. so does that mean, AWD is disconnected during any turning? If so that sucks, and if not, that also sucks. that simply cant work? when someone turns the rear wheels will be cancelling each other out, rubbing up tyres, and wasting fuel. but if my suspicion is right tht it only kicks in if the wheels are straight, then this is a completely useless AWD system, because AWD is meant to help in turning.
cosync just the right drive shaft. Not even a locking diff. It’s essentially a cheaped out version of the S4 sport differential with a prop shaft decoupler in the gearbox with left side permanently connected to the diff and dog clutch on the right. So no thrust vectoring or limited slip
@@danielwaughn5835 yep i worked it out eventually lol. I like the other parts of the system, especially the worm gear clutch cam. Much better than hydraulic whose pump motors overheat. ANd better than BMWs system which jsut gears down using standard gearing to move the camplate.
Audi-developed "Crown Gear" differential. With the new "Crown Gear" center differential, up to 70% of the torque can be applied to the front wheels while up to 85% can be applied to the rear wheels if necessary. This means when its on front wheel drive mod only, 70% power to front wheel. lost 30% for nothing, totally wasted...
when you need 100%, you get 100%... Just not all on the front axis only, which you shouldn't want anyway unless you enjoy an unrefined cookie cutter overpowered fwd.... So, no... not wasted at all

Driving Quattros for 25 years I can tell you this new one is really awesome no matter off or on road. Try it to see yourself.

@@Dandle01Ultra literally has a center differential. The front and rear wheels move independently.

So basically FWD with AWD option.

A torsen based quattro with mechanical lockers should be reffered to "Quattro Ultra" ;)
nice! :) it comes closer and closer to torque vectoring like in electric cars :) well done AUDI!
車子結構越複雜越花錢，我不認為效能不一定會更好。而且車輛壽命不見得更長。
Yes
how about having fixed torque, distribution so semi lock for the centre ?
Lo que deberían corregir son sus cajas automáticas
wow!!! it was Adrive
The 2021 q5 is one of the waste product on the market with the rear dif deficit which needs to be recall by audi....
To much moving parts making

The AWD is not he problem it is very solid but body kit is not prepared to heavy offroad.

bought from who?
@@თენგიზქოპილაშვილი JTEKT Torsen North America Inc owns the patent. Torsen diff was invented by Vernon Gleasman.
권리를 잃다니 지금도 기계식을 계속 사용하고 있는데 고성능 버전 혹은 고급 라인업에는
Good vodieo
So no Torsen anymore.
Goste, mais a ''Subaru'' ta 1 ano luz à frente da ''Audio'', e esse controle de trança eletrônico e da ''Subaru''

Looks cool n' stuff, but i really dont want to know how effecient that is or the price for that matter >.
The original Quatro = torsen diff. system
This is the haldex-quatro
Nándor Fekete it doesn't have haldex clutch you idiot that know nothing about cars.
this is not haldex it is better to be informed.magna powertrain helped audi to study this system
"New Torsen AWD" too bad this thing doesn't have torsen diff. It's just a haldex coupling with maxium 50:50 torque split.

Ein RICHTIGER Allrad hat 4 E-Motoren - Einen pro Rad - that's it - Viel Besser und Viel billiger
Complete mess audi has made. with the rear dif turning on and off causes it to fail and break in no time. The rear dif does not last up 50,000 miles.

AUDI just trying copy Xdrive....
TSI TFSI FSI - NEVER......
Roman Klisiewicz
Nice Audi, copied xDrive...
tesla king car
I don't trust Audi's Quattro tech. They just over advertising for people and they are reusing old mechanism. They should develop electric+program logic on Quattro.
this is xdrive but fwd...
So this Audi's new system is FWD most of the time, now I can say xDrive is better!
As stightliner and poor condition as snow xdrive of course is beter because of 100%torque on rear and suplientary 40% in front.
I have seen BMWs in ditch on snowy roads while my Quattro with all season tires powered thru! 😎🤙🏽

or is it just disconnecting the right driveshaft from the gear inside the diff carrier? perhasp its that.
