RE: power distribution on A4 QUATTRO?
It is a permanent AWD system.
It is regulated within the system (no user regulation capability).
Here's Audi's quote:
History:
In 1994 EDL (electronic differential lock) was introduced. That, along with quattro, enhanced the capabilities of the system. The latest generation came in 1997, when ESP (electronic stabilization program) was introduced. All of these systems are master controlled by the ecu and cannot be adjusted (except for turning off the ESP).

Here's Audi's quote:
Under ideal conditions power is split 50/50 front to rear. But in extreme cases up to 67% of the engine's power can be directed to a single wheel. The benefits to the driver are safety, performance, power, and control in copious amounts.
