Every system offers it owns benefits and drawbacks, and although the more complicated systems are generally excellent they have an attached cost that far exceeds the easier systems.
The downside to the machine is it is very complicated and very expensive, and typically only used for coupling China racing/track applications for its high speed cornering potential.
Torque Vectoring Differential 940x310The yellow arrow highlights the torque transfer occuring through the corner, produced by the artifical level of resistance getting exerted by the TVD externally wheel. This enables for better acceleration out from the corner while the car’s turning abilitty is definitely increased.
A Torque Vectoring Differential is capable of channelling 100% of the available torque through a single wheel when needed in the the majority of extreme of circumstances.
With the TVD exerting more level of resistance onto the exterior 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 experienced under acceleration out of a corner.
By continuing to apply this level of resistance through the part, as the vehicle passes the apex and begins to accelerate out it will continue to override a standard 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 wheels a TVD continues to activate the clutch on the outside 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 in to the part sharper and reducing understeer.
