Every system provides it owns benefits and drawbacks, and although the more difficult systems are generally superior 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 for its high speed cornering potential.
Torque Vectoring Differential 940x310The yellow-colored arrow highlights the torque transfer occuring coupling China through the part, generated by the artifical level of resistance being exerted by the TVD on the outside wheel. This enables for better acceleration out from the corner while the car’s turning abilitty can be increased.
A Torque Vectoring Differential is capable of channelling 100% of the obtainable torque through a single wheel when needed in the many extreme of circumstances.
With the TVD exerting more resistance onto the exterior wheels clutch, it tricks the system into diverting more torque through it – increasing the amount power that can be applied and reducing the understeer experienced under acceleration out of a corner.
By continuing to use this level of resistance through the corner, as the automobile passes the apex and starts to accelerate out it’ll 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, rather than releasing the resistance upon both wheels a TVD proceeds to activate the clutch on the outside wheel only – increasing the resistance experienced 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.
