so it s a limited slip rather than locking. Limited slip would allow movement between the two wheels, locking does not. If thats what it is, why not say limited slip?
I am liking the look more now that I see it, even with a soft top
They use the word locking, because it supposedly is a locking differential... Its just an electronic and variable locking capability perhaps?
So it sounds to me, they have some sort of control over the locking or slipping capability between the rear wheels. If they have done what I think they might, this could be the best of both worlds in terms of traction control and handling. Think about the intelligence they apply to the rear brake pad eLSD, but in the form of actual locking or slipping control. The term locking is probably used loosely, because these features aren't official for a couple more days. I bet this thing handles really well in low traction scenarios.
With a traditional LSD, both wheels will spin equally, nothing intelligent. In this scenario, they would be able to reduce torque to any wheel which is spinning and apply it to the wheel with most grip, and it would be perfectly balanced so that both tires are accepting the maximum torque before traction is lost.
This is really promising for people who want to disable DSC but still have traction intelligence enabled to some degree, or even a form of stability control but via torque vectoring instead of electronic brake interventions.
I think the quattro does individual wheel torque vectoring, and of course Mitsubishi paved the way many years ago with AYC.
BMW has Dynamic Performance Control, but it has been limited to xDrive only as far as I can tell.
The DPC differential features clutch packs on both output sides that are actuated by an electric motor. The clutch pack activates a planetary gearset which causes one wheel to be overdriven.
