Every system provides it owns benefits and disadvantages, 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 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 corner, generated by the artifical resistance becoming exerted by the TVD on the outside wheel. This enables for greater acceleration from the coupling China corner while the car’s turning abilitty is certainly increased.
A Torque Vectoring Differential is capable of channelling 100% of the available torque through a single wheel when needed in the most extreme of circumstances.
With the TVD exerting more level of resistance onto the outside wheels clutch, it tricks the system into diverting more torque through it – increasing the amount power which 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 automobile passes the apex and starts to accelerate out it will 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 hold.
However, rather than releasing the resistance on both wheels a TVD continues to activate the clutch externally wheel only – increasing the resistance experienced by that wheel and making the machine channel more torque through it. This imbalance of capacity to the outside encourages the automobile to turn into the corner sharper and reducing understeer.
