Every system offers it owns benefits and disadvantages, and although the more difficult systems are generally excellent they have an attached price that far exceeds the easier systems.
The downside to the machine is it is extremely complicated and very expensive, and typically only used for racing/track applications for its high speed cornering potential.
Torque Vectoring Differential 940x310The yellowish arrow highlights the torque transfer occuring through the corner, generated by the artifical resistance being exerted by the TVD on the outside wheel. This allows for higher acceleration out of the corner while the car’s turning Differential Gear abilitty is 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 resistance onto the outside 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 apply this 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 quicker 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 proceeds to activate the clutch on the outside wheel only – increasing the resistance skilled simply by that wheel and making the system channel more torque through it. This imbalance of capacity to the outside encourages the vehicle to turn in to the part sharper and reducing understeer.
