Different 4x4 Systems.

This may be old hat to many, and over the last 7 or 8 years I have already read much of the
information myself but for those interested, this site seems to give good descriptions of
different systems even with the odd language issue.

Interesting to see that our buses share a 4x4 system with Lamborghini's Diablo VT and a
couple of Porsche's yummy products.

It fails to mention that the viscous coupling was also use in Fiat Pandas!!!
