I was in Greensboro NC the other evening and needed to get to my sister's house (39 mi) and then home (38 mi). I had 70 miles showing as my range and the temp outside was upper 30's so I stopped at a supercharger before leaving GSO and charged to 120 miles. I figured that should get me the 77 miles needed to complete the trip.
Got to my sister's house with 70 miles showing as range. When I left her house the consumption graph showed I will have 3% charge remaining when I get home. After just a few miles the graph showed "--" as charge remaining at destination. I figured that meant I wasn't going to make it. So I turned off climate control. Within a few minutes it was showing 3% again and by the time I was 5 miles from home it had climbed to 9%. When I got home it was at 8% and range was showing 19 miles. (And I was quite cold!) Both legs of the trip was roughly equal parts interstate and rural roads.
So, the first leg of the trip (39 mi) used 50 miles of range. The 2nd leg (38 mi) used 51 miles. Which is confusing, since the consumption graph clearly showed I was doing better with the heat off (2nd leg). Confusing or not, this was a lesson in how much I can expect to (not) get when it's cold. I'm going to use 75% of displayed range as the actual range I can expect to get when cold.
I'm planning a trip soon to Cherokee NC, passing through Asheville where I'll stop and charge to 100%. Cherokee is about 50 mi from Asheville and there are no chargers in Cherokee (to speak of). Curvy mountain roads all the way. I figure 50 miles to Cherokee, 50 miles driving around, then 50 miles back to Asheville. 150 miles. Think I'll make it? (M3 SR+)
