Every system provides it owns benefits and drawbacks, and although the more difficult systems are generally superior they have an attached price 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, generated by the artifical level of resistance getting exerted by the TVD externally wheel. This enables for better 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 obtainable torque through a single wheel when needed in the many extreme of circumstances.
With the TVD exerting more resistance onto the exterior wheels clutch, it tricks the system into diverting more torque through it – increasing the total amount power which can be applied and reducing the understeer skilled under acceleration out of a corner.
By continuing to apply 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 within wheel, which it perceives as having more grasp.
However, instead of releasing the resistance upon both wheels a TVD proceeds to activate the clutch on the outside wheel just – increasing the resistance experienced by that wheel and making the system coupling China channel more torque through it. This imbalance of power to the outside encourages the vehicle to turn in to the part sharper and reducing understeer.
