lol audi claims this system to be superior to other that have to be locked manually. this is like saying their's the worst system of that type, only better than manual locking diffs :D subaru is the king of 4x4
@seasonedtoker how does the Subaru system work?. If I recall arent Subaru Drivetrain Layouts very similar to Audi's? where theres a Fore-Aft Engine in front of the Front axles and then power coming of that, unlike for example, the Evo's who uses a Transverse mount. but whats their primary difference?
@RoarkeRandall It's cheaper to learn how to drive than to buy a car that intervenes and "does some of the driving" for you. I don't see anything wrong with driving more slowly if you know the roads are wet. A Honda Accord is more than sufficient for the purposes of getting to work. If an Audi breaks down, good luck finding a mechanic who knows how to work on one. You're basically at the mercy of the few that do know.
@nobleheight Perhaps you're right. But if some retard who doesn't know how to drive goes sliding in front of me and I need to swerve, I am not able to apply breaks to an individual tire. I feel that there is no doubt that this system is superior for the unlikely cases of losing control. Whether or not it's worth it, that's up to marketing and opinion.
@nobleheight went to work yesterday morning in a blizzard with roads covered in ice and snow, had sooo much fun :D and i drive 1998 Peugeot 406 diesel so imagine replacing my car with this in those conditions, i would miss work by at least 3 hours :D
Another Audi fanboy listen bro I don't give a shut bout ur differential crap I'm just saying sh awd happens to be more advance since it not only transfers power front to back but side to side a worlds first Audi uses a dated technology now and all it does is lock the differntial-simple
@sayeedrehan Right, right. And first man in space was African. Do you have any more fairy tails? SH-AWD doesn't even have a center differential so how can it be better? (This video is mainly about new center differential.) And if you are talking about rear differential, than there is something called Sport Differential and Cross-Axle Torque-Vectoring.
If the front wheels are slipping, a static clutch in the centre differential between the crowngear on the rear axle and the centre differentials bellhousing creates friction between the crowngear and the bellhousing, thus transfering more torgue to the rear axle.
There's a cluch for the front axle's crowngear too, but it's not as beefy as the one to the rear, so it does not create as much friction, and thus less torgue goes to the front.
something I don't understand: when u loose traction on one axle, it seems to me like this dif is just letting it spin faster than the side WITH traction. So if you treat the extreme case, 0 traction in front (for example) then the front will just spin and the rear will have no angular velocity!? Seems to me like this device is just ALLOWING a deferential speed between front and rear. how exactly are you transmitting more torque?? confused!
I like that split differential...pretty cool, but the braking idea...nothing new there. The real improvements will be within the engine itself. The manufacturing processes are very important in the overall product such as the manufacturing process of a crankshaft; for instance the design could be spectacular, yet the end product may need a lot of attention when balancing, due to a bad manufacturing method.
I love engineering! Just can't wait to graduate next year!
This shit is awesome! Logical engineering principles with acceptable manufacturing costs. Brilliant! I don't have to wear a space helmet to understand this stuff; I just wonder how long it sat on a shelf before the suits let it be built and tested for their newest rides?
@CadJack These mechanical principles and methods I can see being put on some drivelines of home-built rides of those that have some automotive know-how and machine shop experience. The braking is just well added fluff for a consumer who wants to have a total seamless affordable traction control system.
@TiaraAlonso That's not the American attitude I am used to. Come on! Stop putting yourselves down. Is there Prozac for a nation? Seems like America needs a good dose of it now.
Omfg stop arguing witch car is faster..... Mclaren F1 is wooden cart compared to this. Mclaren don´t even have Turbo, abs ... absolutely ancient and yet it would out run all of your M3 or M6. This is about using more advanced 4x4" and reach the maximum contact with road. Making car safer and more efficient. This video is just explaining how stuff works. I am glad I found it these ideas are just amazing. Sry for my english.
@timsurftim I have owned a '92 325i, '98 M3, '04 M3, and '04 S4. The S4 just did not even compare in terms of reliability, performance, fun, handling, etc. Hands down, Bimmers are the better car and every person i know that has actually OWNED both a Bimmer and Audi's or Mercedes will always tell you that Mercs and Audis are just Bimmer wannabes.
This told me nothing about how the mecanics worked at all. Yes, it was a nice animation and all that, but I still don´t understand a ... eh ...thing, else than that the brakes engages at turning...
@Torvikholm This new center differential is non-planetary design, but splits asymmetrically (40/60) (look where each side gear connects to the pinion, they are at different heights)
There is no 'self-locking' from the applied torque, but from the spring pre-load on the clutch packs. (which is conveniently omitted)
@Torvikholm Friction always works against you, right?
The spring pre-load on the center differential develops a frictional torque (both in static & dynamic), so when differentiating, that frictional resistance works against the faster spinning axle-reducing its torque (and works 'against' the rear, to 'speed up' the slower rotating axle)
That is how you go from nominal (front/rear) 40/60 to 15/85, and 40/60 to 70/30.
This is the same mechanism the TorSen differential employs.
Personally I'd prefer a locked center differential with a permanent 50/50 power split between the front and rear axles... Something easy to fix, understand, and explain to other people, with the least amount of failure-prone technology as possible.
@SparkDischarge I'm pretty sure pick-up trucks use selectable locking/ 4x4 differentials... if so equipped, otherwise having RWD & a standard limited slip differential... but that's for a different story.
Regardless, what I was talking about would be more like a permanently locked/ welded differential, where each wheel gets an equal split of the power, regardless of how many wheels are on or off the ground, as if the driven wheels were driven by a common shaft, if not so.
@seth570123 Currently there are no pickup trucks for sale in the US that have a center differential.
Most use a traditional selectable transfer case that has: rear axle drive : off-road drive (where the front driveshaft is coupled to the rear driveshaft) : neutral : low-range off-road drive
By the design of the coupling, the axle speeds are made the same. The torque can go anywhere it feels like going. (look at the extreme weight bias of diesel 4x4s pickups. Some in excess of 60% front heavy.)
@killer2600 i agree with you. the modern-day cars are just too much in terms of complexity and cost. I just want basic AWD without the electronic gizmos and tons of plastic, double climate control, electric seats, cupholders etc etc in the interior. Look at the interiors of racing cars..very minimalistic but very practical! And if something breaks it can be fixed in minutes!
First, this audi quattro system has nothing to do anymore with old generation ones: much better and evolved. Here 2 main components: planetary gear center diff and torque vectoring. In comparison, Subaru install such a system + lock ration capability (more sophisticated), but no torque vectoring (based on the ESP principle). Mistubishi installs a active yaw controller to dynamically drive the car from the rear wheels (more sophisticated). The audi system stays a safety system, not a dynamic one
@rozzan007 - this system can be had with the sport differential... which is like yaw control. Overall though... by virtue of it being able to move a greater range of torque through the two axles.. it is safer and more dynamic. Plus it's lighter.... and gives up less frictional losses. All those things make it more dynamic... even without the optional sport differential (which i'm not sure if it's standard on the RS5).
@AdMiRaLeDpIeTt No. In fact the RS5 has device in exhaust system that spray some gasoline and set in on fire to make some flame when you change gears:) Perfect car for fuel crisis... on the other hand, when you can afford such a car you don't need to save fuel unless you want to.
@AdMiRaLeDpIeTt - well it reduces frictional losses and it's lighter... so comparing apples to apples (same vehicle) it would reduce fuel consumption. Audi is focusing on reducing the weight of it's vehicles overall... which is the main disadvantage of AWD. Now look at the new A8 and A6... they weigh the same or less than their RWD 7 and 5 series competition. That says a lot for fuel consumption and dynamics.
@STATEOFTRANCE14 AWD is a marketing term. Have a center differential + a lockup clutch for the center differential + clutch pack to couple/decouple the front axle.
Rear wheel drive :center differential locked, front axle transfer clutch open
Four wheel drive :center differential not fully locked (open-closed as needed), front axle transfer clutch closed
Rear drive+PTO :center differential locked, front axle transfer clutch-variable, this allows for oversteer on demand.
wow this video was so informative. Its exactly what i wanted to know about the new Quattro system. BTW does anyone know if this is the same quattro system as the one the R8 has or does the R8 have a different type?
Yes, it does wear the pads out sooner, plus the car will be using extra fuel to maintain speed going through the twisties, basically the car is riding its brakes. Torque Vectoring via braking sounds great on paper, but in the long run, it has to be an efficiency nightmare. I don't want complexity to increase anymore than the next guy, but if someone could invent a hybrid of the Torsen differential and a Detroit locker, Torque Vectoring could be accomplished mechanically, and efficiently.
@atommajewski Check out the Lancer Evolution with AYC. Uses a hydraulic multiplate clutch on the center and rear differential to control torque without using the brakes.
Also handles better and is rather affordable compared to an RS Audi. I love my Evo IX personally.....
@photoren Well, considering that the Lancer was/is a front wheel drive car, from a standpoint of weight distribution and inclined roll-axis, and that it will lift its inner rear wheel at will.
Mitsubishi needed a speed sensitive system to transfer power from the spinning lifted wheel to the outer one. A simple viscous coupling on the rear differential seems pretty low-tech.
The AWC (and S-AWC) was Mitsu's answer to that, and it works very well
@powerinvader xDrive (the new system of a computer controlled clutch pack instead of a planetary open center differential) works better at the extreme situations of usage, such as lifting a wheel or axle.
A torsen differential will need brake actuated traction control to prevent power from just flowing out of that lifted wheel/axle.
Quattro is four wheel drive (not the Haldex), where xDrive is rear wheel drive with a power take off system.
@boltjet135 lol m3s are cetainly not blown away by these vehicles, well performance wise anyway, but i do believe technology wise to a certain extent.
@TheSheldon038 the m3's are fast and fairly basic but i personaly prefer audi and it's my opinion that they give m3's and m5's a good beating on all parts, maybe not ride quality
@boltjet135 i also prefer audi. But you cannot deny that hte m3 has had superior performance for the past few years often beating merc and audi in comparison tests.Maybe this will dethrone it
@TheSheldon038 cetainly te m3's a beast but the cars are fat in different ways, bmws more vicouse will the audi more sedate and the mercs have to much power but there cool

audi are the masters of 4 wheel drive, started with the quattro and now with the beautiful rs5, m3's are blown away by these beast's, they are icons

@boltjet135 lol m3s are cetainly not blown away by these vehicles, well performance wise anyway, but i do believe technology wise to a certain extent.

@TheSheldon038 the m3's are fast and fairly basic but i personaly prefer audi and it's my opinion that they give m3's and m5's a good beating on all parts, maybe not ride quality
boltjet135 1 year ago
@boltjet135 i also prefer audi. But you cannot deny that hte m3 has had superior performance for the past few years often beating merc and audi in comparison tests.Maybe this will dethrone it
TheSheldon038 1 year ago
@TheSheldon038 cetainly te m3's a beast but the cars are fat in different ways, bmws more vicouse will the audi more sedate and the mercs have to much power but there cool

Those exposed gears are bound to get mud into themselves.
I'm afraid of them.

@seapeddler They're not exposed. They are housed within a special casing.
