Every system offers it owns benefits and disadvantages, and although the more complicated systems are generally excellent they have an attached cost that far exceeds the simpler systems.
The downside to the system is it is very complicated and very 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 corner, produced by the artifical level of resistance being exerted by the TVD on the outside wheel. This allows for better acceleration out of the corner while the car’s turning abilitty is certainly increased.
A Torque Vectoring Differential is capable of channelling 100% of the available torque through an individual wheel when needed in the the majority of extreme of circumstances.
With the TVD exerting more 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 vehicle passes the apex and starts to accelerate out it will continue to override a standard 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 grasp.
However, instead of releasing the resistance upon both tires a TVD continues to Differential Gear activate the clutch externally wheel just – increasing the resistance experienced simply by that wheel and making the system channel more torque through it. This imbalance of capacity to the outside encourages the automobile to turn into the part sharper and reducing understeer.
