Every system has it owns benefits and drawbacks, and although the more complicated systems are generally excellent they have an attached price that far exceeds the easier systems.
The downside to the system is it is extremely complicated and incredibly expensive, and typically only used for racing/track applications because of its high speed cornering potential.
Torque Vectoring Differential 940x310The yellow-colored arrow highlights the torque transfer occuring through the part, produced by the artifical level of resistance becoming exerted by the TVD externally wheel. This allows for better acceleration from the corner as the car’s turning abilitty is increased.
A Torque Vectoring Differential is capable of channelling 100% of the obtainable torque through an individual wheel when needed in the the majority of extreme of circumstances.
With the TVD exerting more level of resistance onto the outside wheels clutch, it tricks the machine into diverting more torque through it – increasing the amount power which can be applied and reducing the understeer skilled under acceleration out of a corner.
By continuing to apply this level of resistance through 
the part, as the vehicle passes the apex and starts to accelerate out it’ll continue to override a coupling China standard multiway-LSD – which would again interpret the quicker moving outside wheel as slipping and divert torque during acceleration to the inside wheel, which it perceives as having more grip.
However, rather than releasing the resistance upon both wheels a TVD continues to activate the clutch on the outside wheel only – increasing the resistance skilled simply by that wheel and making the machine channel more torque through it. This imbalance of power to the outside encourages the vehicle to turn into the part sharper and reducing understeer.
