What is a viscous Limited slip Differential?
Do both rear wheels spin when lose of traction happens?

vdc is only offered on the Track model, and Performance.

And all but the base has Traction control.
Which one of these is most important in winter driving?

Here you go.

Compared with current AWD+ABS+TCS systems, this new system enables the
vehicle to be handled at the limits of adhesion during cornering,
acceleration and braking with greatly improved control, providing safer,
smoother driving under all conditions. For example, you may enter a corner
at what you think is the correct speed, but then realize halfway round that
your speed is excessive for the road surface. This forces you to
overcompensate and lose traction. Excessive speed on slippery road surfaces
can also lead to the car spinning out or even overshooting a corner. VDC
reduces the possibility of such overreactions, assisting the driver to
maintain control and avoid accidents. The major difference between VDC and
the AWD+ABS+TCS systems is the motion element being controlled. VDC offers
2-dimensional control as opposed to the 1-dimensional control provided by
AWD+ABS+TCS. The AWD+ABS+TCS system senses the vehicles speed and
acceleration in a straight line only, and uses these data to control braking
and driving forces in order to prevent loss of traction. By contrast, the
new VDC system provides 2-dimensional control by also sensing the
transversal movement of the vehicle and its yaw (rotation around the
perpendicular axis). It uses these data to predict the vehicle's direction
in 2 dimensions and to control it within safe limits. The VDC system
recognizes the course a driver wishes to take from the steering wheel angle
and vehicle speed. It detects the current driving conditions from the wheel
speed sensors, longitudinal and transversal G sensors and the yaw velocity
sensor, and simultaneously estimates the coefficient of friction (potential
loss of traction) of the road surface. It uses this information to predict
the actual direction of the vehicle, and minimizes the difference between
the desired and predicted course by controlling the driving and braking
forces. When a potentially unstable situation is predicted because the
desired course and the cars actual course differ, the braking and driving
forces are controlled to regain stability. Vehicle speed is also limited if
necessary by reducing engine output and torque.


Hope this answers your questions.
