Every system provides 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 machine 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 becoming exerted by the TVD on the outside wheel. This allows for higher acceleration out of the corner while the car’s turning abilitty is definitely increased.
A Torque Vectoring Differential is with the capacity of Differential Gear channelling 100% of the available torque through a single wheel when needed in the most extreme of circumstances.
With the TVD exerting more level of resistance onto the outside wheels clutch, it tricks the system into diverting more torque through it – increasing the amount power which can be applied and reducing the understeer experienced under acceleration out of a corner.
By continuing to use this level of resistance through the part, as the vehicle passes the apex and begins 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, rather than releasing the resistance upon both wheels a TVD continues to activate the clutch externally wheel only – increasing the resistance experienced by that wheel and making the system channel more torque through it. This imbalance of capacity to the outside encourages the vehicle to turn into the corner sharper and reducing understeer.
