Syncro is VW's tradename for all-wheel drive, regardless of the technology
employed.  In the case of the Golf, Jetta and Vanagon/Eurovan, it is a
viscous coupling system.  In the case of Quantum and the new B5 generation
Passat, it will be an Audi based system (aka quattro).

Of course it gets more complicated.  Audi has traditionally used the three
differential system which we have been acustomed to calling quattro.
 However, in the A3 and TT (which are based on VW's next-generation Golf
platform -- perversely called the A4 platform internally!) will use a
VW-style viscous coupling all-wheel drive system.

So what it is coming down to is that neither "quattro" or "Syncro" define a
particular system architecture.  They simply indicate which manufacturer has
its name on the car.
