Some call it Syncro, some call it Quattro....isn't that a song or something.
 
Speaking of models imported to the USA, there's the Vanagon Syncro that uses
a viscous coupling to attach the transmission to the front pair of wheels.
 The coupling acts like an automattically engaging differential that will
lock when the rear tires begin to loose traction.  Then, there's the Quantum
Syncro.  Since VW choose the name Syncro to market their all-wheel-drive
offerings, they applied the name to the Quantum as well even though the
Quantum used the Quattro system from the Audi 4000.  The Quantum and the 4000
being very similar cars, including their drivetrains, it was simple for VW to
start selling a Quantum Syncro without designing a new drivetrain for it.
