> What is the difference between an 80 and a 90 (type 89) model ?
Trim and equipment level, engine choices (usually 4 cyl for 80 and 5-cyl
for the 90). Actual chassis and most of the running gear is the same
example. 90 quattro 10v and 80 quattro have the same drivetrain.
> When exactly does the Audi Quattro was rechristened Audi quattro ?
I think this was when Audi decided to start producing other models with
that drivetrain. circa 1983-84. Probably a slow gradual change, not an
exact moment in time.

Yes, this is also true for WR cars. My '85 had that system.
