That means when
wheel slip occurs and traction is compromised, the many Mercedes - Benz active safety and driver assistance features work in cooperation with the all - wheel drive system.
One example of PTM in action is when rear
wheel slip occurs.
The moment
wheel slip occurs, this feature can send up to half of the CLA's power to the rear wheels for improved traction.
Not exact matches
My guess is this
occurs because manufacturers worry about driveline lash / wear, about uncontrollable
wheel slip, or they think we're totally inept and are messing up the whole process.
By locking a differential at a front or rear axle, you are inhibiting any
slip from
occurring at the axle, forcing each
wheel at said axle to turn at the same rate.
When sensors detect that
wheel slip is occurring or even just likely to occur, the All - Wheel - Drive (AWD) system can react within as little as 50 milliseconds to distribute up to 100 percent of the available torque to the rear w

Wheel - Drive (AWD) system can react within as little as 50 milliseconds to distribute up to 100 percent of the available torque to the rear
wheels
The system then determines the optimal amount of front and rear torque for the given conditions to not only reduce
wheel slip but to prevent the
slip from
occurring in the first place
As a result, all -
wheel - drive performance is on hand even before
slip can
occur — not only on snow and loose gravel, but also through dynamically taken corners — and the engine's full power is transmitted to the road.
When
slip occurs at one of the axles, the clutch redirects the majority of the torque input to the
wheels with the better grip.
If a
wheel at the inside of a curve begins to lose its grip when cornering at speed, it is braked slightly before any
slip occurs — this keeps the RS 5 Cabriolet neutral for an exceptionally long time in extreme driving conditions.
A limited
slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping
wheel, while still allowing some
wheel spin to
occur.
Self - locking differentials (a.k.a. Limited
Slip Differentials) address this problem by adding to the classic, free or open differential, described above the ability to lock (drive both
wheels at the same speed i.e. simulate the differential's absence) under certain conditions such as when
wheel spin
occurs.
That helps you, as the driver, to be aware of where
wheel slip is
occurring and when traction is low so you can alter your drive accordingly.

Wheel Drive with active twin clutch automatically adjusts torque to each wheel to optimize traction and respond before slip oc

The 4MOTION all -
wheel drive of the Golf R, which has been perfected with such features as a Haldex - 5 coupling, is activated even before
slip occurs.
If the load on the inside
wheel is reduced too much while the car is being driven dynamically, the torque vectoring system brakes it slightly before unintended
slip can
occur.
It reduces the
slip that
occurs on the
wheel with less grip by transferring more drive power to the other
wheels using a blocking effect.
The system uses a TORSEN ® limited -
slip locking center differential to distribute power 40:60 front - to - rear, directing more power to the
wheels with the best grip should slippage
occur.
