He and I probably have similar driving behavior. At 100% the other day mine showed 360 miles. Of course, I don't believe it. A trip meter I reset in early April shows I'm averaging 2.5m/kwh. But that included a few highway trips. Take those out and around town I'm getting closer to 2.7 which accounts for it. I suspect the GOM uses more recent driving history 30 days maybe? This pic after charging last night to 85%. the 296 shown comes from 130kw X .85 X 2.7 /I'm impressed by your range estimate. We apparently have 2 very different driving styles / environment's. ( I'm assuming past driving habits factor into future estimates ) any time I charge to 100% , the highest range I've ever gotten was 320.
