Every system has it owns benefits and drawbacks, and although the more complicated systems are generally excellent 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 because of its high speed cornering potential.
Torque Vectoring Differential 940x310The yellow arrow highlights the torque transfer occuring through the part, generated by the artifical resistance becoming exerted by the TVD externally wheel. This allows for better acceleration out from the corner while the car’s turning abilitty is increased.
A Torque Vectoring Differential is capable of channelling 100% of the obtainable 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 total amount power which can be applied and reducing the understeer skilled under acceleration out of a corner.
By continuing to use this level of resistance through the part, as the automobile 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 inside wheel, which it perceives as having more grip.
However, instead of releasing the resistance upon both tires a TVD continues to activate the clutch on the outside wheel only – increasing the resistance coupling China experienced simply 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 corner sharper and reducing understeer.
