My '91 200q (Lehmann chipped) gets fuel mileage pretty much in line 
with what Taka reported--high twenties and sometimes even a bit 
better on the highway at a steady 75-80 mph. Of course that's "Audi 
mph", which is really closer to 70. I've never driven at a steady 65, 
so I can't say what that would be. ;-) My computer's MPG output was 
adjusted years ago to be within about 5% of actual fill-up 
calculations, and I verify the "calibration" from time to time. While 
I routinely get 27-29 MPG on the highway, I can get as high as 30-31 
over long, flat stretches (125 miles) when I really concentrate on 
using a steady right foot, avoid "aggressive" passing and stay below 
80. There are many times that I seem to get better economy using of 
my own right foot rather than the cruise control.

The same car--around town--gets no more than about 18 MPG.
