This can SO get out of hand.....

(I think) Torsens are never locked.  Locked means 50/50 split, no matter
what.  Both axles (or wheels) turn always in sync.  With A Torsen this only
occurs when driving straight and level, and it's still not "locked,"  Does
that make sense?

... an *open differential* has a constant 50:50 torque split.  A locked
differential can go anywhere from 0:100 to 100:0 depending on the traction
on both ends ... as you note, both ends are forced to rotate at the same
rate ...
