Every system offers it owns benefits and drawbacks, and although the more complicated systems are generally superior they have an attached cost that far exceeds the easier systems.
The downside to the 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, generated by the artifical resistance getting exerted by the TVD on the outside wheel. This allows for better acceleration out of the corner as the car’s turning abilitty is increased.
A Torque Vectoring Differential is with the capacity of channelling 100% of the obtainable torque through a single wheel when needed in the most extreme of circumstances.
With the TVD exerting more resistance onto the exterior wheels clutch, it tricks the system into diverting more torque through it – increasing the amount power which can be applied and reducing the Differential Gear understeer experienced under acceleration out of a corner.
By continuing to apply this level of resistance through the corner, as the automobile passes the apex and begins to accelerate out it’ll 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 hold.
However, instead of releasing the resistance on both wheels a TVD continues 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 power to the outside encourages the vehicle to turn in to the corner sharper and reducing understeer.
