re comparing saabs bmw s in article lth oninn r exodus eng sun com tut cairo eng sun com bill bill tuthill writes for a reasonable sum you can get a bmw with traction control a torque sensing limited slip rear differential traction control as far as the optional feature that one buys with cars is not the same thing at all as a torque sensing differential a torque sensing differential is a type of lsd but not all lsd s are torque sensing viscous coupled differentials as opposed to viscous couplings are rotational sensing not torque sensing for that matter so are traction control systems that use abs sensors and pulse braking then there are the older posi tracs and whatever which i am not familiar with the workings eliot
