Every system offers it owns benefits and disadvantages, and although the more difficult systems are generally excellent they have an attached cost that far exceeds the easier 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, produced by the artifical level of resistance getting exerted by the TVD externally wheel. This enables for greater Differential Gear acceleration out from the corner while the car’s turning abilitty is 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 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 resistance through the part, as the automobile passes the apex and begins 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 inside wheel, which it perceives as having more grasp.
However, instead of releasing the resistance on both wheels a TVD proceeds to activate the clutch on the outside wheel just – increasing the resistance experienced simply by that wheel and making the machine channel more torque through it. This imbalance of capacity to the outside encourages the automobile to turn into the corner sharper and reducing understeer.
