Drop in efficiency last month

Cold.
1. Battery pack has to be heated to its operating temperature, which is far less energy efficient than cooling when it is hot out. Since day 1 (Broder) this has been an issue. Less so in Model 3 than in its older brethren, and less so in warm environments (Miami?) then colder locales, but still an issue.
2. In addition, the are other things more efficient when warm out - like your tire pressure is likely higher - so rolling resistance should be much lower - in the warmer months.
3. How much wet weather driving now vs then? How about wind - does it vary in Miami? Lastly, does your driving pattern vary now vs then?
Measure again in May.

Shorter trips. Average November trip is 28% less than average August trip. Shorter trips are less efficient as a rule.
Heating costs a LOT more power than cooling, and its likely "cooler" than it was when you were getting better efficiency numbers. Note, I didnt say "cold" I said "cooler". If you are driving the same, its "weather" (cooler so using heating and may not realize it, more wind, wet streets, etc).
Im not touching the "battery degradation" or lack thereof. Plenty of reading in the master thread above, which is likely where this thread should be moved to if you want to have that discussion.
