More Gold!!

In order to satisfy that demand on the part of performance-oriented spirited drivers, as of March 2008 the 135i will be fitted with the NEW DSC function program that simulates the action of a mechanical differential lock. The system uses the typical BMW open type differential and is comprised solely of an electronic intervention program inside the DSC.
When the vehicle is in tight bend the DSC applies the brakes the spinning (inside) driving wheel, the torque is then transmitted to the outside wheel which is carrying most of the load, optimizing power and maintaining vehicle speed trough the corner. The new function implemented in the DSC control module is thus, in effect, DTC without modulation of engine output. The DSC and DTC functions are unaffected by it.
BMW High Traction DSC applies brake to the Low Traction wheel that loses traction.

Indisputable proof of new functionality to the DSC!!!

In comparison with a mechanical differential lock, the advantage of the new DSC program function is more than just the fact that it is substantially more cost effective. Whereas a mechanical differential lock is permanently active, this DSC Function only comes into action only when required and if the DSC/DTC is switched off. Nor does it add to the vehicle weight and fuel consumption.
Furthermore, the function does not affect handling stability in DSC or DTC mode and the familiar understeer tendency produced by mechanical differential locks is also avoided.
The feature will also be introduced on BMW 3 Series models with higher performance engines at a later date.

Not in the 3 series cars at all right now...
