I have a new niro - one week old. Today, the "Inst Fuel Economy" bar was pegged all the way to 75mpg, even when i was going 70 miles per hour. The little hybrid "tree" was all blue, and the EV light was on most of the way home, even at 70 mph. So for a 28 mile trip it said i was getting 63.5 mpg. I did reset average mpg but that didn't make a difference. Any ideas as to way may be going on?
