Every system offers it owns benefits and disadvantages, and although the more complicated systems are generally superior they have an attached cost that far exceeds the easier 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 Differential Gear 940x310The yellowish arrow highlights the torque transfer occuring through the part, produced by the artifical level of resistance getting exerted by the TVD on the outside wheel. This allows for higher acceleration from the corner as the car’s turning abilitty is certainly increased.
A Torque Vectoring Differential is capable of channelling 100% of the available torque through an individual wheel when needed in the many 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 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 corner, as the automobile passes the apex and begins to accelerate out it will continue to override a standard 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 hold.
However, instead of releasing the resistance on both wheels a TVD continues to activate the clutch externally wheel only – increasing the resistance experienced simply by that wheel and making the machine channel more torque through it. This imbalance of power to the outside encourages the automobile to turn in to the corner sharper and reducing understeer.
