My first 38 mile trip to work after the update this morning - about 1/2 of it highway and 1/2 county/city roads. was going 70+ mph on battery for a couple of miles and got an overall 48.4 mpg (without hard trying) - the best for me so far for this trip. I guess the only difference I could tell was the over 62 mph on battery and the better gas milleage at the end. I guess time will tell....
