I remember my dad's Chrysler Intrepid having a flat MPG curve to it too.

I took the Intrepid out on the TC highway going west From Regina to Moose Jaw (very flat road) and this is the FE laydown:

Temperature 16*C, winds SE @ 20km/h
Each FE reading was done after 2 miles of driving at the stated speed

40 mph = 32.3 mpg
45 mph = 34.9 mpg
50 mph = 35.7 mpg
55 mph = 32.7 mpg
60 mph = 29.9 mpg
65 mph = 29.4 mpg
70 mph = 29.2 mpg

I find it interesting that a): the mileage gets worse below 50mph (maybe due to the torque converter not locking?) and b): the mileage seems to plateau with speeds over 60mph. Evidence of good aerodynamics? It's pretty sad that the V6, 3600 pound Intrepid gets just a few less mpg's less than the Geo @ 70 mph .
