pawoSD. You have a good point. My 500 has good torque at 2000 but better at 3000. Now 75 mph is 2500 so I will probably leave it that way. This car will get 20 mpg on the highway so I guess I should just leave it alone. The best mileage I ever got was 23 and that was on a tank of fuel going from NC to Fla. I was running along with a group of truckers. Not drafting or anything, but I know they knew where the smokeys were and was running at 90 to 100 for quite a few miles. I know that a lot of the people here will say that is impossible to get batter mileage at that kind of speed, but think about this. In Germany these cars were designed to run 140+ mph all day long. At that rate, they wouldn't get but 25 or 30 miles per tank if you believe that higher the speed, lower the mpg. I say that a car can be designed to run very high speed and get good mileage doing it. but low speed mpg suffers. Using state highways, I am lucky to get 15 mpg. 10 mpg in stop and go traffic. If I run into a good buy on a 722.5 I may try it anyway.
