Drift Mode?
Anyone figure out how to enable this? GLC63/S. With the addition of 4matic+ I thought someone might have figured a software update as it is available on other variants with the 4matic+
Just a pipe dream maybe :-) figured I'd ask.

There is definitely no drift mode on 2020 GLC63.

Not sure if this is an automated item but from Mercede's GLC63 Coupe website:
"Power to the pavement, precision in the moment
- AMG Performance 4MATIC turns torque into traction and agility. The GLC 43's 31:69 rear bias quickens takeoffs and clings to corners. Variable-torque 4MATIC+ in the GLC 63 and GLC 63 S can send up to 100% of the engine's torque to the rear axle . "

Your post is both accurate and sucinct. Being an old gear head, I'm still wondering about the 0:100 torque split of the 4MATIC+ installed in the GLC 63. A while back I saw a video which included a MB test driver who said that the system could switch from 100% rear torque to 100% front torque in micro seconds. It seems to me that for this to happen the front drive system (drive shaft, ring and pinion gears, and front half shafts) need to be constantly engaged--even iff it is only at the 1 or 2 percent torque level. I was curious as to perhaps the torque split start point might be different depending on which mode is selected--ie S or S+ but it seems AMG is reluctant to release any information on this other to say it is controlled by a complex matrix. Any thoughts?
PS: I'm pleased with the performance of my 31:69 torque split AMG C43, but I'm considering an AMG GLC 63 before the V8's go away!

Now the clutch that transfers power/torque to the front wheels can be engaged in milliseconds. These are multi-plate clutches that are operated hydraulically with very high pressures, so they can go from fully open to fully engaged in milliseconds. The same technology is used in the electronic locking differential, which can adjust the locking ratio multiple times a second based on traction needs etc. However, there's again marketing speak with being able to send 100% to the front with 4MATIC+. That also needs to be explained more to understand. At maximum the clutch can fully close and effectively lock the rear axle to the front axle. That's equivalent to a center diff lock. In that case you have a 50:50 torque split. So a full clutch lockup can only send 50% to the front, The remaining 50% can only be achieved based on traction again as described in my post above. Once the clutch is fully engaged (50:50 split) and the rear wheels have zero traction, only then will the front wheels receive 100% of the torque/power. That is different from the 100% it can send to the rear, because it can decouple the front axle, so true 100% is forced to the rear regardless of traction.

Confirmed ideas and thoughts.
I have a 2018 GLC43 and put it into Dyno mode using the process with the steering wheel buttons and ignition in pre-accessory. I was able to drive it on the streets and still had power steering.
I can confirm it makes the car behave in a “RWD only” mode. For anybody wants to do donuts or have more fun in the snow, this is the way to do it. Of course all your baby sitters are turned off and you better know what you’re doing, but it’s RWD only. And if the fronts doing anything, I didn’t notice.
