Hi, Al - - -
Your note sounds like an interest in a new car, but if not . . .
We have one of each, a 98 V70XC with the viscous coupling and an 02
S60AWD, with the Haldex electronic system. Neither has failed to
provide less than what we felt was needed. You have no idea that the
car is so equipped until it *doesn't* make a noise you were expecting,
or etc.
The current (Haldex) is the more flexible, in that the vehicle can be
towed with one set of wheels not turning, where the viscous coupling
required all four wheels to be off the ground if going for an unexpected
run to the Dealer. Since this has never been necessary with either
vehicle, that info is of philosophic interest only, but adds a measure
of reassurance in these days of no "fall-back" from anything that has
upset the onboard computer.Good luck,
