Piano_Tuner, not that I would assume I can teach you how to hypermile, and by all means, your results are very good at 52mpg (not many car in the US can do that today...) but I think you can achieve better mpgs by keeping a constant speed. Acceleration does not need to be like a snail (my opinion... and depend what is considered "like a snail"...) and I'm not sure coasting in neutral is the best way (I could be wrong...)
With my commute route, my ideal speed for mpg is between 65 and 60mph. I try to remain in this range, bringing the car to 65mph and "accepting" a deceleration to 60, and I figured the best I could get, with this commute, if I don’t mess up with any mpg killing stuff, is a max of MID 62mpg with the I2. At 50mph max, as you describe for your commute, I'm quite convinced you can cross the MID 70mpg mark on a tank average, by keeping a constant speed. The I2 seems to be maxed out in mpg capabilities around 48mph. By keeping a 50-45mph range, it seems quite easy to coast very long distances with MID showing 90mpg. Depending how would be your total commute (many stop & go), I believe the average could cross the 70 mark.
My recommendation would be : once you get to speed, lift your foot until you find the "balance" where the mpgs are maxed out and the speed remain constant. The assist/charge to be neutral (no assist, no charge). At a constant speed, it seems to me you can either keep you foot in place to keep your speed constant, or lift it up a little and still keep your speed constant, but get a 10 to 15mpg more on the live mpg screen (the bars showing the mpg). I don't know why, since the I2 does not have lean burn, and this looks like a lean burn behavior (I1 drivers, please confirm...I've personally never seen the lean burn in action, just read about it).
In a recent post, jraynor was describing part of his driving style, using the roller-coaster style.
Cooler temps, less mileage
(hope you are ok if I refer to you J…
). This is what I do also, though I think my average speed is just a tiny little higher than him. So far, we get about the same mpg him and me (if I refer to fuelly.com), second behind Greendriver, who I suspect has a commute using 50mph roads. J and I both live in northern country (Massachusetts, Michigan) and commute seems quite similar. Both of us were showing 56-58mpg per tank before the cold (MID 58-60). The winter weather will impact us more than it will do for you in California.
By all means, I’m not pretending to be the hypermiling expert, but this is what I learned with the I2. I hope it can give you some idea how to go beyond your 52mpg mark.
I'm up to 52.7
Pretty good!
