At 80 the Grand Prix turns about 22-2300 rpm. Just think if it had a 5th gear in it. One thing that's not so obvious is that the computer in the car is a complete custom tune for that car at my altitude, so it's really not a stock car by any means, it's got custom fuel and air mapping which contributes to that figure. In hilly areas, or not on cruise control I wouldn't be able to hold that high of a mileage, it also helped I went from 7200' elevation to 5200' during that trip- the way back I got about 30 mpg, and that included a lot of slower and varying speed due to the minor blizzard that set in the last 30 miles.
