Every system provides it owns benefits and disadvantages, and although the more difficult coupling China systems are generally excellent they have an attached cost that far exceeds the easier systems.
The downside to the system is it is extremely complicated and very expensive, and typically only used for racing/track applications because of its high speed cornering potential.
Torque Vectoring Differential 940x310The yellow arrow highlights the torque transfer occuring through the corner, generated by the artifical resistance being exerted by the TVD on the outside wheel. This enables for greater acceleration out of the corner as the car’s turning abilitty is certainly increased.
A Torque Vectoring Differential is capable of channelling 100% of the obtainable torque through an individual wheel when needed in the the majority of extreme of circumstances.
With the TVD exerting more level of resistance onto the outside wheels clutch, it tricks the system into diverting more torque through it – increasing the total amount power that can be applied and reducing the understeer experienced under acceleration out of a corner.
By continuing to use this 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 inside 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 experienced by that wheel and making the system channel more torque through it. This imbalance of power to the outside encourages the automobile to turn into the part sharper and reducing understeer.
