Every system provides it owns benefits and drawbacks, 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 extremely 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 Differential Gear through the part, generated by the artifical level of resistance getting exerted by the TVD externally wheel. This enables for higher acceleration out of the corner while the car’s turning abilitty is 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 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 automobile passes the apex and starts 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 hold.
However, instead of releasing the resistance upon both wheels a TVD proceeds to activate the clutch externally wheel only – increasing the resistance skilled by that wheel and making the machine channel more torque through it. This imbalance of capacity to the outside encourages the vehicle to turn into the part sharper and reducing understeer.
