: Pardon my possible lack of technical knowledge, but what you are describing doesn't any make sense. I don't see how ASC can act as an LSD, distributing a specified percentage of torque to the opposing wheel when the opposite wheel is losing traction. Applying the brakes cannot possibly distribute torque across the wheels like an LSD can

My personal opinion is that you are correct - the ASC+T (now DSC) does not "distribute" the traction forces.

It is BMW that says "the function of limited slip differential has been performed by the ASC+T (since the intro of the E38) therefore it is no longer necessary to install a limited slip differential".

To confuse matters more I heard that they are planning on an LSD on some models of the new M5 - which also has DSC.


The only way you can be 100% sure is to actually talk to the design engineer for traction - and I don't know who that is - but it might be worth sending a letter to Germany directed to that title.

Cheers
