The winter was very bad for my range. The change to the snow tires made no difference. (Note: they're mounted on the same wheels, I only have one set of wheels.) The cold made a large difference. The sticky snow on the road clogging up my tread and wheel wells made an *enormous* difference. Torrential downpour with rain-soaked road was really bad too. (I had all of this happen on my trip to Michigan. At the time, I recorded the average *for the trip*, but I seem to have thrown it away. It was just a tad under 600 wh/mi.)

This months stats. Late but here.
 
354 Wh/mi, with last 1500 miles (roughly) on 19" tires instead of the 21s. 20,241 miles total.

But a good chunk of the recent mileage was in wind and rain between superchargers on I5 -- going for speed, not efficiency, in that case.

My theory for why Oregon data seem to be badly outlying has just been reinforced by Josh's input coming from Anchorage. These two states have, in my millions of miles of driving experience throughout all of North America (except Nunavut, NWT and Newfoundland), the worst road surfaces of any US state (YT's are equal, but no Teslas there).

Road surface quality has an immense effect on fuel consumption. I've noticed it for decades with my diesel pickup trucks. Anecdotally now, but two otherwise comparable terrains would give me perhaps 22mpg if a good surface and 11-13mpg if a crappy one.
You have a good point. I hate WA road surfaces as well.
 
Requested update: our car has averaged 337 wh/mile over the past 21,187 miles. (The car has a few more miles than that on it; the odo somehow got reset around 1,310 miles).

We have had 19" Pirelli winter tires on for the whole time. It's an S85. My wife is a fairly sedate driver, but I like to make sure nobody watching a Tesla leave a stoplight thinks electric cars are slow.

IMO, this speaks volumes about the impact of "environmental conditions" (as compared to driver style, 60 vs. 85, etc.).

A sedate driver on 19" tires and I know Chad takes road trips so if you remove his highway travelling, I suspect his numbers would be in the 370+ range.
 
Been away from the forum, however do want to post our car has averaged 321 wh/mile over it's lifetime. Just hit 36,000miles. Now that spring is here I think the car will settle in at 320 wh/miles as I don't do as many "jack rabbit" as I did in the beginning and spring and summer the car consistently gets about 316 wi/miles. Winter and driving style is what eats the watts. 19" Goodyear tires under a standard 85.
