Not sure if you were replying to me but that doesn't really go into technical details. I was looking for a mechanical explanation how more force could go out one pinion gear rather than the other when the spider gear should put equal force on both when rotating together with the ring gear.

Planetary gears arrangement give torque split options other than 50:50. Normal spider gears give exactly 50:50

itix, below are couple of simple images I sketched, to give you an idea how an asymmetrical diff can physically look. Most asymmetric diffs actually do not use this arrangement, but this is a simple way of representing an asymmetric diff and should you decide to use such simple design in your vehicle, it will still perform such function.
So here it is starting with an image of symmetric diff for reference:
And the asymmetric one:
You can see how in the asymmetric diff, one of the side gears is smaller than the other which would result in smaller torque being applied to the shaft connected to that side gear.Last edited by NickRally; 4th July 2017 at 23:35.

Nick, that’s a solution I’ve never seen before. Does such differential actually exist?
Audi has a nice looking solution for torque split. This crown gear differential has a torque split front/rear = 40/60. The rear axle is rotated with a bigger diameter/radius than the front axle and therefore get more torque.

A video of how it works.

The figure on page 311 explains the torque split of a planetary differential (Old Ford with a front/rear torque split 34/66).

Prepare to 2018? How? Let same engineers come to same drawing-desk with same philosophy? For what reason it should be something rather than C3 again?
I think that they must found a problem of C3 and a solution. Test at 2017 rallies and if it works - it's make a car a way faster, even to 2018 year.
They are "prepare" with same approach with same stuff and we see what kind of results they have
