Every system provides it owns benefits and drawbacks, 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 for its high speed cornering potential.
Differential Gear Torque Vectoring Differential 940x310The yellowish arrow highlights the torque transfer occuring through the corner, produced by the artifical level of resistance becoming exerted by the TVD externally wheel. This enables for higher acceleration out from the corner while the car’s turning abilitty is usually increased.
A Torque Vectoring Differential is capable of channelling 100% of the offered 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 system into diverting more torque through it – increasing the total 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 vehicle passes the apex and starts to accelerate out it’ll 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 inside wheel, which it perceives as having more grasp.
However, instead of releasing the resistance upon both wheels a TVD continues to activate the clutch on the outside wheel just – 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 automobile to turn in to the part sharper and reducing understeer.
