I live in cali too I believe its from the 10% Ethanol, I have a 98 m6 even when i baby it, still get about the same city mileage as you. I have new tires, plugs wires and filter are good. New fuel filter tire pressures good, shocks and struts are bad and the cats might be 02 sensors are fine. Any other ideas?

M6 in 2nd OD = 1.71 final drive ratio (3.42 x .5). A4 in OD = 1.83 (w/2.73's x .67) or 2.17 (w/3.23's x .67) final drive ratio.
I find myself at just about 2k rpm in 6th going about 80mph in the 98 and about 2800rpm at 75 in the 02 (has 3.73 gears x .67 = 2.50).
