Saturday I got home from the grocery store in my wife's MME, and when I turned the car off, it asked me if I wanted to allow an update. At the time the remaining range was 211 miles. Half an hour later, without plugging in, range was updated to 275 miles. Not sure if they found some efficiencies in the system, or just employed a more aggressive algorithm (or both), but seems like an interesting update given all the recent negative press regarding EV range in colder winter weather that has been out lately.

That’s is certainly could be a benefit of over the air updates, I remember Tesla did something similar. Maybe they gave you more of the pack to use in cold weather.. certainly couldn’t get range over the air in an ice truck. If they found more efficiency that would be truly impressive.

I would drain it down and allow the BMS to recalibrate. I don't think they found that much by way of improved efficiencies or unlocked buffers, most likely it is an inaccuracy caused by loading a new software revision (i.e. not all modules and gateways have been cycled and run since restarting).

I totally agree!

I don’t think the change in Estimated range is a tangible real range increase but is due to a change in the algorithm used to estimate range.

This increase could also be partially temperature related as well but glad to hear it either way!
Temp did not go up significantly in the half hour it took to run the update. I have noticed that the car does not stay at 100% for as long as it used to. I used to be able to get about 30 miles on back roads, or 10 on the freeway before it started to show a drop to 99% now is more like 10 and 3 respectively. Am probably getting the same true range, but car is able to somehow quantify that full charge portion, and allocate miles to it.
