[urq] Info on old school Quattro Rallye car?

[Max Wellhouse]

Listees:  I remember as a young man reading a foreign car mag article 
on an Audi rallye car that had an engine in the back and an engine in 
the front and separate shifters for each transmission.  It apparently 
kicked butt in whatever events it competed in.  I guess back 
then(70's?) it was somewhat of an engineering marvel to get both 
throttles to be in sync.

Does anyone else recall this vehicle and have any further info on it?

Thanks,
