Have driven the Spark just over a thousand miles (so, fairly new to the 'experience').
Like a lot of the people on here, I have been playing the game. That one where you watch to see how well you are driving based on the MPGe scores. (Since I have not paid for the electricity, it shouldn't matter, but somehow I still have to get a better score).
The question I have is; Has anybody else noticed that the Lifetime MPGe (based on the OnStar app) somewhat depends on the SOC (battery level) point that you have decided to "fill the tank" again is? Meaning; when I charge (always L2) the car when the battery has been more depleted the Lifetime average goes up more, when I charge when the battery is mostly full then the Lifetime avg will drop slightly.
It seems like it may have something to do with how the batteries charge slower (less efficient) the closer they are to 100% and the app seemingly adjusting the MPGe based on the charge efficiency.
I'm guessing/hoping that Mr.DRMorgan (and perhaps others) have data that can validate charge efficiency changes based on the battery state of charge.
