So, what you're saying is that when I drove in to work today at ~70 miles per hour (I was running late) and actually increased my MPG for the straight, flat land that you can't drive fast and still maintain good FE? If that's true then one of the following must also be true: a. my car is different from yours b. my computer is malfunctioning c. I'm a liar
I'm just telling you what I see, obviously the car doesn't maintain a steady 70 MPG at 73 miles per hour, for long stretches, that wasn't my point I've seen it for minutes at a time, it's not just a momentary thing. At 68 the car will on straight, flat land the car will get me over 50 MPG it will dip into the 40's occasionally, but it goes right back up and maintains it for miles at a time. I wish I could prove it to you, but short of video nothing would do so. I do notice though that when I get that mileage that the electric motor is very frequently pitching in, never dipping below the third bar, and also mind you that this is with cruise control on and I never get traffic.
