In our 2013 RAV4-EV, the GOM shows a max of about 70 or less because we drive it short distances. Typically, each bar in our car is worth about 6 miles of range. So 15 bars would = 90 miles. Remember it is called GOM ("Guess-O-Meter") for a reason. The only time our GOM is even close to accurate, is when we regularly drive it down to 10 miles or less. Otherwise, as I drive I add up the current GOM reading and the distance driven in my head and watch it steadily increase (i.e. the GOM reads 68 after I have driven 10 miles = 78; it reads 63 after driving 20 miles = 83) up towards 100. Also if you watch the bars drop out, you will see that you lose 1 bar every 6 miles (on flat terrain) so you can easily see that you will make close to 90 miles (with 15 bars). I used to drive between Northern California and Southern California (500 miles) so I got used to how to read the GOM.
