As others have commented, warmer weather = better range.
Happy to report with the recent stretch of a week with over 40F (much in the 50/60 range), have passed 200 miles on a charge (with hilltop mode charging).
Here in WV, I am starting to see 250 exp., 290 max. Yea, warm, dry weather. Of course, that is based on how I drove yesterday. On a long trip, NOT driving 40-45 mph, I won’t see that! However, I drove to work & back today @ 5.2 mi./kWh.
Here's what a bit of warm weather in Montana looks like... Mostly in town driving, 25-45/40-70 mph/kph with a bit of highway driving. No Interstate driving. Temps in the 50s and 60s, the warmest so far this year. That's about to come to a close as we're headed back into the 40s for a bit.
