Point is, if the last time you drove touched a lot of efficiency hot buttons, (low speed, ambient temp, stop and go driving, light on the accelerator) then the calculated miles at 100% charge will be higher. I recommend not taking the miles number too seriously, and only focus on the percentage. Once you start a trip, the remaining miles number will continue to adjust based on the efficiency hot buttons that change.
However over a period of time, if the miles number consistently decreases, then you may be experiencing some battery losses.
My Lightning at 63k miles is showing no loss, but my MME at 85k miles might be showing a 5% loss.
But both vehicles have exceeded my expectations. I honestly do not understand why these vehicles aren’t selling better than they are? Ford needs to advertise, advertise, advertise. When was the last time you saw Ford EV advertisement on TV?
Recently charged my 2024 Flash (still the larger ER battery, not the down-sized Flash for '25) to 100% and found the GOM to read 334. This was surprisingly high, but also understandable, as the GOM extrapolated from a lot of local 35-45 mph driving at high efficiency. The 190 mile mixed driving round trip I charged up for, at 35 mph/ 45 mph/ 65 mph for most of it, left me with 140 miles still on the GOM upon returning home. So the GOM, surprisingly, was actually accurate with its prediction.
