Every system has it owns benefits and drawbacks, and although the more coupling China complicated systems are generally superior they have an attached cost that far exceeds the simpler systems.
The downside to the system is it is very complicated and incredibly 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 corner, produced by the artifical level of resistance being exerted by the TVD externally wheel. This allows for higher acceleration out from the corner as the car’s turning abilitty can be 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 exterior wheels clutch, it tricks the machine 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 level of resistance through the part, as the vehicle passes the apex and begins to accelerate out it will continue to override a standard multiway-LSD – which would again interpret the quicker moving outside wheel as slipping and divert torque during acceleration to the inside wheel, which it perceives as having more hold.
However, instead of releasing the resistance upon both tires a TVD continues to activate the clutch externally wheel only – increasing the resistance experienced by that wheel and making the system channel more torque through it. This imbalance of capacity to the outside encourages the vehicle to turn into the part sharper and reducing understeer.
