Every system offers it owns benefits and disadvantages, and although the more complicated systems are generally superior they have an attached cost that 
far exceeds the simpler systems.
The downside to the machine is it is extremely 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, generated by the artifical level of resistance getting exerted by the TVD externally wheel. This enables for greater acceleration out of the corner as the car’s turning abilitty is certainly increased.
A Torque Vectoring Differential is capable of channelling 100% of the offered torque through an individual wheel when needed in the most extreme of circumstances.
With the TVD exerting more 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 skilled under acceleration out of a corner.
By continuing to use this resistance through the corner, as the vehicle 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 within wheel, which it perceives as having more hold.
However, rather than releasing the resistance upon both tires a TVD continues to activate the clutch on the outside wheel just – increasing the resistance experienced by that wheel and making the machine channel more torque through it. This imbalance of power to the outside coupling China encourages the automobile to turn into the part sharper and reducing understeer.
