Every system offers it owns benefits and drawbacks, and although the more difficult systems are generally superior they have an attached cost that far exceeds the simpler systems.
The downside to the system is it is very complicated and incredibly expensive, and typically only used for racing/track applications for its high speed cornering 
potential.
Torque Vectoring Differential 940x310The yellowish arrow highlights the torque transfer occuring through the part, produced by the artifical level of resistance getting exerted by the TVD externally wheel. This enables for better acceleration out of the corner as the car’s turning abilitty can be increased.
A Torque Vectoring Differential is with the capacity of coupling China channelling 100% of the offered torque through an individual wheel when needed in the many extreme of circumstances.
With the TVD exerting more level of resistance onto the exterior wheels clutch, it tricks the machine into diverting more torque through it – increasing the total amount power that can be applied and reducing the understeer experienced under acceleration out of a corner.
By continuing to apply this resistance through the part, as the automobile passes the apex and starts to accelerate out it will continue to override a 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 hold.
However, instead of releasing the resistance on both wheels a TVD proceeds to activate the clutch externally wheel just – 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 in to the part sharper and reducing understeer.
