You do, and you can....
No the system is 100/0 75% of the time the remaining its 95/5 now if the system detects slip it goes to 50/50.

The system uses real-time input data on steering angle, yaw rate, lateral G force and engine status to determine road surface and driving conditions. The active torque coupling mounted in front of the rear differential is electronically controlled accordingly, adjusting front/rear wheel torque distribution between 100:0 and 50:50 to deliver optimum drive power to each wheel. The result is powerful acceleration and positive handling regardless of constantly changing road conditions, as well as the ability to fully balance the car in a turn by deft use of the accelerator pedal.
The Mazdaspeed6's onboard computer automatically determines driving and road conditions so the driver can relax and enjoy the pleasure of the drive. Three different modes of front/rear torque distribution are selected by the system: Normal, Sports, and Snow, (for slippery surfaces). The Power Take Off (PTO) system that that aggressively distributes torque to the rear axle is fitted with its own water-cooled cooling system.
A new rear differential with greater torque capacity is employed by the system to deliver a high level of reliability. Increased torsional rigidity of the propeller shaft and rear differential mount improves the response of torque transfer to the rear wheels and delivers a more rigid feel to the ride under acceleration. And a limited slip differential is used in the rear differential optimizes transfer of torque to the left and right rear wheels, realizing solid traction and linear vehicle control that delivers a stable feeling ride when cornering.

the mazda awd system is on all the time, the solenoids are constantly working during all driving time and increase and decrease directly as the drive changes (bumps in the road, a slight curve, braking, etc). the awd system is NEVER "stuck" on one percentage EXCEPT for snow mode which is 95/5% front to rear, and this only happens when you see the blinking traction button going off. otherwise the awd system is fluctuating power constantly between all 4 wheels. even with cruise control on with no boost on a straight road, all 4 wheels get power. the front wheels just get most it during calm cruising.

You are correct, but the 'snow' mode typically defaults to 50/50 distribution.
Watch this video... http://www.youtube.com/watch?v=uOWGq1B8C84
You have power to all the wheels... AWD... all the time.

sport mode would be defaulted to 50/50 if there even IS a default, and i'm pretty sure that DSC cuts all but a tiny bit of power to the rear wheels when you are "stuck" in the snow or on ice or a slippery hill incline, because even though in the snow you can rip it hard, thats really SPORT Mode, and when the blinking traction light comes on thats mazdas snow/ice mode for safety. DSC-on is the only time you will get snow mode (unless you are driving slowly in DSC-off, i have had the light blink on a rough industrial road and also over train tracks). but the good snow driving that we see on youtube is really SPORT mode with DSC off and the center diff in constant fluctuation, this car really has no defaults since it decides itself when to turn on and off (even though it is NEVER off), its never sitting on a percentage and sticking to it, its regulating percentages nonstop from 100% fwd all the way to 50/50% awd and even from side to side with every change in the road and driving style.

Yeah, the DSC off changes everything, you're not running with a 'safety net' of power cut. Try driving in the snow with it on, then switch it off and do the same thing...big difference. The yaw, steering angle, and throttle position sensors still control power, but aren't held back by the ECU.
When the DSC is ON, you have full time AWD, but the amount of F/R torque bias is adjusted by the AWD module via the duty cycle on the pilot clutch solenoid. When you turn DSC OFF and going forward above a walking pace, you have full time 50/50 AWD controlled by the amount of grip in the coupling clutch. The ramp/pivot in the diff coupling applies more clamping force if there is any speed difference between F/R. The more torque applied, the tighter the coupling grips to maintain the 50/50 drive. You can set it to FWD ONLY by installing a manual switch in the wires to the pilot clutch. If you open the circuit, the rear coupling is completely disabled and you are FWD only.
If you have DSC OFF and launch the car hard, the front tires will turn just a bit more than the rears at the initial movement until the coupling builds enough clamping force to bring the rears into full lock with the fronts. Then you get AWD tire smoke. Been there, done that and that's how it works...
