Every system has it owns benefits and disadvantages, and although the more difficult 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 for its high speed cornering potential.
Torque Vectoring Differential 940x310The yellow arrow highlights the torque transfer occuring through the corner, produced by the artifical resistance becoming exerted by the TVD externally wheel. This allows for better acceleration out of the coupling China corner while the car’s turning abilitty is definitely increased.
A Torque Vectoring Differential is capable of channelling 100% of the offered 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 total amount power which can be applied and reducing the understeer skilled under acceleration out of a corner.
By continuing to apply this level of resistance through the part, as the vehicle passes the apex and begins 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 grip.
However, rather than releasing the resistance on both tires a TVD proceeds to activate the clutch on the outside wheel just – increasing the resistance skilled simply by that wheel and making the machine 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.
