Errrr no! It's permanent although the viscous differential will vary the amount typically it's 5% front, but can reach 40% under extreme conditions.

The front propshaft can be disconnected however ;)

No (unless I am very much mistaken) - but only a very small % goes to the front wheels under normal conditions.

Porsche Stability Management

To be more precise:

PSM (Porsche Stability Management) is a far more comprehensive stability control system. PSM 5.3 was introduced as an option on the 1999 Carrera 4, and PSM 5.7 became an option on all models from MY2000.

"PSM is an active control system for stabilising a vehicle at the limit of its driving dynamics capability. PSM includes functions such as ABS, ABD, ASR (traction-slip control), EBV (Electronic Brake-force Distribution), as well as a longitudinal dynamics control system MSR (engine drag torque control). In addition to this, the vehicle is stabilised at the limit of its driving dynamics capability within the transverse dynamics control system by FDR (driving dynamics control system)."


Lots of nice acronyms for you to get your head around there!
