I haven’t looked closer to the AYC before because it looks so complicated to understand. I found some pages which clarified (not completely though) how it’s working. The link below is from a Russian page with nice pics with the route of the torque. https://www.drive2.ru/l/3188140/

The next one shows the difference between AYC and Super AYC (S-AYC). As I understand the AYC “steals” the torque from the other drive shaft and transfers it via the clutch plates and gears back to input. The S-AYC “steals” the torque from the other drive shaft and transfers it directly to the other drive shaft.

A couple of pics of the S-AYC where you can see more clearly what is connected to what.

“MMC introduced AYC, the first component system of its type in a production car, in August 1996 (EVO IV). Switching from a bevel gear to a planetary gear differential in January 2003 (EVO VIII) doubled the amount of torque AYC was able to transfer.”
What I don’t know if it is possible with a planetary differential to have a torque split of 50/50. Usually planetary differentials have been used with unequal torque split to have a more rear wheel drive feeling.

Front / Rear torque split 45 / 55.
Nice pics where can been seen which gears are connected to which clutch pack.

Re 2017 aero packages... VW are saying the Polo's was kept conservative to be tougher and stay in place over a whole stage, rather than just a few km then be damaged by cutting etc.
Have the other teams homologated too much aero which wont last the distance on the rallies ?

The big crash was in Shakedown with full aero attached.
There's just a clip of him later sliding with no rear wing ... but still on the road.
With the 2017 cars having big aero at both ends surely they could be very unstable if front or rear parts get knocked off...
If the Polo was conservative in its aero to avoid this I assume Ogier will want MSport to make sure the Fiesta is built stronger. Its aero looks the most developed but also the most fragile of the new cars.

And Solberg's moment in Mökkiperä. Off at 2:55 and jump at 4:10
I bet a 17' car would be twice as bad as this.

It looks to me that the rear diffuser on the fiesta has been designed so that if it does break off there is also one designed into the rear bumper that will have an effect with the lower part missing.
I read that Citroen tested a fair bit to see what effect broken bodywork would have on their car. Interesting to see that the bodywork on the c3 changed from more boxy design on front wing similar to other cars, to a simpler flare more similar to their own WTCC car.

Great that Kopecky finally has some competition in the Czech Championship, Barum should be mega!
