After researching your charger's specs I read about something called esp and braking control... on these of vehicles the brakes act as I described above...lightly slowing one spinning tire to transfer power to the other. It's also used on High end suvs and is designed to improve traction on less than ideal surfaces.

I am aware that the 2009 Challengers didn't have lsds...a major fax paus on Dodges' end.
