I can't belive you never dissamble or hold in hand torsen diff? I refuse to belive in that.
Yes in condition where one wheel have zero or little above zero traction, (pure ice or wheel in air) you will have all torqure on that wheel.
But on road when car is move that is close to imposible scenario. Washers in torsen diff will never let torque to go in front or rear wheel 100%. Bias is alwasy around 70:30%
Broken driveshaft have nothing comon how torsen work. Beacuse as I sad, when all wheels are spining there is load on tosren washers and that change game a lot.
It has everything in common. If there is zero traction at one wheel, the one wheel will spin, and others will stand still. It's simple mathematics. The torsen differential is not capable of locking up like a LSD.
Jack up one corner of the car and turn the EDL off, the car can't move off the jack.
Washers in torsen diff will never let torque to go in front or rear wheel 100%. Bias is alwasy around 70:30%
This is complete horseshit. Any situation where one wheel is lifted or driveshaft broken the car isn't going anywhere.
But I feel dump that I need to explain that to you.
If all teory you guy say now is true, that will mean that quattro in all B4, C4,D2 is pure bull shit, that quattro without EDL/ESP is nonsense. But we all know that is not true.
C4 and D2 already had EDL... And yes, the Audi Torsen based 4WD is completely useless offroad. That is why the Q7 did not use it, and instead a fully locking transfer case was developed.
Explain to me how old quattro have 1.7 sec 60 ft at 1/4 mile?
If you have right, that will mean at start one wheel will spin like car is FWD or RWD, try it you will see that is imposible!!!
Because there is some traction to that wheel. As soon as it spins, the total power transmitted to the ground becomes less due to that wheel spinning and it regains traction, because basically the system balancing itself. The wheel can not stay lifted. But the car accelerates much faster with EDL braking that wheel or a front LSD. All the fast drag cars used welded center diffs exactly for this reason back in the day. The 60ft time was 0.3-0.4s better with a welded diff.
The acceleration is
much better with EDL. I even did some tests a long time ago with 2 wheels on ice and 2 wheels on tarmac. The difference in acceleration with EDL on was more than 2x.
I drive quattro for more than 10 years, 3 different cars without ABS, EDL, ESP or rear diff lock.
From drag to snow, back again to track and normal road. And I feel dump to even discuse about this on this audi/WV forum
You drive it for 10 years and you lack elementary knowledge about how the system works.
I guess it just goes to show time and time again, that you can take something apart and put it back together without having any clue how it works. Very true of engines as well - bolting it together does not make you a tuner or understand how any of the processes work inside.
But hey, keep digging an even bigger hole for yourself.
You really never broke a driveshaft on a quattro car? You haven't done shit in your life then lol. I probably broke a driveshaft before you had a license.
Btw the really old Audi cars did not use Torsen based 4wd. They had a manually locking diff in the center. Torsen was introduced in the late 80s.
And EDL was found on all D2 and also on A6/S6 C4. On all the non-EDL cars to get them unstuck in deep snow, so one wheel isn't just free spinning on front, it was needed to apply the brake and gas at same time, then you'd get some traction to the other wheels. Was still needed on the late C4 cars if you got really stuck because the EDL was pretty anemic on them.
