I find that very hard to believe, given that drag increases with the third power of velocity. By almost unnoticeable do you mean that you didn't notice it, or did you robustly measure and compare?
- causi 4y agoIt's entirely possible, even likely, the lack of difference is due to age-related efficiency losses at lower speeds rather than not losing efficiency between 70 and 80. There's also the fact I'm running AC on max in very hot weather, which maximizes the loss due to AC and increases the amount I save by shortening the trip and thus reducing the amount of time the AC is running. My overall trip efficiency maxing out at 70 was 31mpg, and 80 was 27.9mpg.
