Every system offers it owns benefits and drawbacks, and although the more difficult systems are generally excellent 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 yellow arrow highlights the torque transfer occuring through the part, produced by the artifical level of resistance becoming exerted by the TVD on the outside wheel. This enables for better acceleration out of the corner as the car's turning abilitty is increased.
A Torque Vectoring Differential is capable of channelling 100% of the available torque through a single wheel when needed in the many 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 experienced under acceleration out of a corner.
By continuing to use 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 faster coupling China moving outside wheel as slipping and divert torque during acceleration to the inside wheel, which it perceives as having more grasp.
However, instead of releasing the resistance on both tires 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 part sharper and reducing understeer.
