Every system provides it owns benefits and disadvantages, and although the more difficult systems are generally superior they have an attached price that far exceeds the simpler systems.
The downside to the machine is it is extremely complicated and very expensive, and typically only used for racing/track applications because of its high speed cornering potential.
Torque Vectoring Differential 940x310The yellowish arrow highlights the torque transfer occuring through the part, generated by the artifical resistance becoming exerted by the TVD on the outside wheel. This allows for higher acceleration out from the corner while the car’s turning abilitty is definitely increased.
A Torque Vectoring Differential is with the capacity of channelling 100% of the offered torque through a single wheel when needed in the the majority of extreme of circumstances.
With the TVD coupling China exerting more level of resistance onto the exterior wheels clutch, it tricks the system into diverting more torque through it – increasing the amount power that can be applied and reducing the understeer experienced under acceleration out of a corner.
By continuing to apply this level of resistance through the corner, as the automobile passes the apex and begins to accelerate out it’ll continue to override a normal 
multiway-LSD – which would again interpret the faster moving outside wheel as slipping and divert torque during acceleration to the inside wheel, which it perceives as having more grip.
However, instead of releasing the resistance on both wheels a TVD continues to activate the clutch externally wheel only – increasing the resistance experienced simply by that wheel and making the machine channel more torque through it. This imbalance of capacity to the outside encourages the vehicle to turn in to the part sharper and reducing understeer.
