Every system offers it owns benefits and drawbacks, and although the more difficult systems are generally superior they have an attached price that far exceeds the easier systems.

The downside to the coupling China machine 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 arrow highlights the torque transfer occuring through the part, produced by the artifical resistance becoming exerted by the TVD externally wheel. This allows for better acceleration out of the corner as the car’s turning abilitty is increased.

A Torque Vectoring Differential is capable of channelling 100% of the available torque through a single 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 machine 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 use 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 faster moving outside wheel as slipping and divert torque during acceleration to the inside wheel, which it perceives as having more hold.

However, instead of releasing the resistance on 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 power to the outside encourages the vehicle to turn in to the corner sharper and reducing understeer.
