Every system has it owns benefits and disadvantages, and although the more difficult systems are generally superior they have an attached price that far exceeds the easier systems.
The downside to the machine is it is extremely complicated and incredibly expensive, and typically only used for racing/track applications because of its high speed cornering potential.
Torque Vectoring Differential 940x310The yellowish arrow Differential Gear highlights the torque transfer occuring through the corner, generated by the artifical resistance being exerted by the TVD on the outside wheel. This allows for greater acceleration from the corner while the car’s turning abilitty can be increased.
A Torque Vectoring Differential is with the capacity 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 exterior wheels clutch, it tricks the machine into diverting more torque through it – increasing the 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 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 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 automobile to turn in to the corner sharper and reducing understeer.
