Just happened today; my results kinda shocked me (in a good way
. My '12 Leaf w/12 bars and nearing 22k mi. Left home with a full charge, returned with LBW and 1 bar/5mi on GOM. Overcast, in the low-80s, no big elevation changes, and traveled a total of 81.4mi. Big majority of the trip was interstate driving at 55-65mph, windows up with A/C on (72 degrees), on surface streets no A/C and windows down. Always in ECO mode, with the dash showing an average of 4.7 mi/kWh. I kept my speed constant on the interstate, and stayed in the right lane behind a work truck (not tailgating). Only used cruise for a few miles (set at 60).
I bought used and have only had her for a few weeks. I am thrilled (and relieved) that I can drive her just like my former ICE cars. Up until today I was getting from full to VLBW (dashes) in around 70-75mi, with little or no A/C. Last night I checked the tire pressure, all 4 were 34-35psi. Bumped them all up to 40psi then came home and charged overnight. I have also noticed that my GOM is mostly accurate, especially on the lower end. When I was 35mi away from home according to the NAV, for example, the GOM read 40mi. That 5mi 'cushion' between my mileage home and the GOM remained fairly constant for the entire trip (within 1mi).
