Is the Porsche 924 really an Audi?

Hi All,

I would like your help to have a rumor confirmed or debunked.  I seem to
remember hearing sometime ago that the engine in the Porsche 924 was derived
from an Audi truck engine.  Now I have no idea if Audi even makes trucks,
but I would be interested in knowing if the engine rumor is true.  Also, I
may be bordering on herecy here, but did Audi and/or VW share any engine
designs with Chrysler?  I ask because some time ago I was assisting a friend
to repair his 85 LeBaron GTS, and I noticed his engine looked like an
oversized VW 1.8L 8V.  Any thoughts?
