Every system has it owns benefits and disadvantages, and although the more complicated systems are generally excellent they have an attached price that far exceeds the easier 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 yellow-colored arrow highlights the torque transfer occuring through the part, produced by the artifical level of resistance being exerted by the TVD on the outside wheel. This enables 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 available torque through a single wheel when needed in the most extreme of circumstances.
With the TVD exerting more resistance onto the outside 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 level of resistance through the part, as the vehicle passes the apex and starts to accelerate out 
it’ll continue to override a normal multiway-LSD – which would again interpret the quicker moving outside wheel as slipping and divert torque during acceleration to the inside wheel, which it coupling China perceives as having more hold.
However, instead of releasing the resistance upon both wheels a TVD continues to activate the clutch externally wheel just – increasing the resistance skilled 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 corner sharper and reducing understeer.
