This allows the system to prevent a wheel from spinning in extreme conditions on slippery road surfaces or when the two rear wheels are experiencing significant differences
in friction coefficient.
So where there are significant differences
in friction coefficients between the right and left rear wheel, for example, optimum traction and maximum propulsion power are ensured.

Coulomb's equation states that
in order to slide one hand against the other the shear stress — akin to the force applied to slide your hands — divided by the surrounding pressure — squeezing the sand together — must equal something called the
friction coefficient.
The clutch plates
in the four - wheel drive system now have a higher
friction coefficient, which ensures even faster and more precise torque distribution to the front axle, while the rear axle still features a torque vectoring differential.
The degree of lock — which may be anywhere between 0 and 100 percent — is adjusted as required within a fraction of a second, enabling wheel spin to be prevented on slippery surfaces,
in instances where the right and left rear wheel have widely differing
friction coefficients,
in tight bends and when changing direction with particular vigor.
Further improvements have been made
in various areas, including the car's directional stability, the
friction coefficient of the wheel bearings, tire noise and weight, which has been reduced by 4.4 pounds on the front suspension alone.
Depending on driving style and the
coefficient of
friction, it can send between 50 and 100 percent of the available torque to the rear axle, and when Audi drive select is
in dynamic mode and the ESC Electronic Stabilisation Control system is
in its sport setting, power is transferred to the rear sooner and
in greater amounts for even greater agility and more direct turn -

It is an active all - wheel - drive system that helps to ensure the optimal distribution of drive power for optimum traction
in most road scenarios, whether on long straights, through tight corners, or on surfaces with different
friction coefficients.

in the Audi drive select dynamic handling system enables adaptation of the most important ride dynamics parameters to the
friction coefficient of the road.
They are far lighter and have much higher
friction coefficient and needs a total reworking of the servo system
in order to avoid the horrible lurching stops the first gen systems were known for.
The degree of lock — which may be anywhere between 0 and 100 per cent — is adjusted as required within a fraction of a second, enabling wheel spin to be prevented on slippery surfaces,
in instances where the right and left rear wheel have widely differing
friction coefficients,
in tight bends and when changing direction with particular vigour.
Through an oil - temperature sensor, the SH - AWD ® Control Unit monitors the rear differential's clutch - plate
coefficient of
friction (that changes with temperature)
in each clutch pack and then adjusts the voltage to each electromagnetic coil to compensate.
It's more rugged, to accommodate higher torque, and its
friction coefficient increases to adjust front / rear torque flow
in quicker, more precise increments.
With reactive activation, which rarely occurs
in practice, the system reacts to sudden changes
in the
coefficient of
friction.
In dynamic mode, power is sent to the rear axle sooner and to a larger degree, improving the driving dynamics particularly at low
coefficients of
friction.
quattro all - wheel drive is more frequently active
in winter than
in summer because the
coefficients of
friction are lower then.
Lowering
friction coefficients in video game physics is a move that says now we are having fun!
Note that
in these two papers we not only derived wind velocities, but also theoretically determined turbulent
friction coefficient — something
in principle unachievable
in conventional simulations (where this
