Does anyone know if the EPA rating of 265 miles range for the 85 kWh reflects range mode or normal mode?

I understand that charging in standard mode stops at 90% SOC of range mode, equaling 76,5kWh. Driving it to empty should give near 90% of 265 = 238 miles. So I'd say well beyond 200 miles in most everyday driving situations.
You are correct. Standard holds back both the top and bottom 10%. But if you're in a situation and you need that bottom 10% it's still there, just hidden from you.Question: But, doesn't the discharge stop at about 10% SOC? Or did I misunderstand those battery basics? If it stops around 10% SOC, then range would practically speaking be about 212.

Yes, this is a recently revealed difference between the Roadster and the Model S.No. The Model S does NOT stop at 10%. You can drive to 0% without worry. "Range Mode" for the Model S only refers to charging the top 10% of the battery.
.......So I don't understand all this talk of less than 240 miles. If you are driving around 60mph through mild climate conditions (i.e. not cranking the AC), shouldn't you get around 300, if not north of that?
In this thread, Rod and Barbara post their real-world experience so far with range. Very interesting, but they still have a bunch of things left to try.

Interesting; thanks!
So, assuming we'd usually want to charge in Standard mode (to 90%) to be relatively gentle on the battery, at 338 Wh per mile,
85 kWh pack => 226 miles (85 x 1000 x 0.9 / 338) as Rod and Barbara said.
60 kWh pack => 159 miles
40 kWh pack => 106 miles
And, Rod/Barbara said that it was with moderate acceleration bursts while they test their car out so, with consistently aggressive driving, these could be a tad lower.
Good to have some real, real world numbers!
Although it is interesting to know how much average driving you could do in standard mode if you wanted to, I don't think these are the most relevant numbers. (Except perhaps for the 40 kWh pack.) (EDIT: However, for the 40 kWH pack the weight is probably smaller by a degree that decreases energy consumption, and improves range.)
I'd expect that on the large packs (maybe the 60 KWh pack is somewhere in between), you are limited by the capacity only when driving on the highway. (As long as you can charge each night, how would you otherwise get up to such a mileage?).
And on the highway, it seems more important to know what energy consumption is at various (more or less) constant speeds. Of course, once one knows the energy consumption at various constant speeds, one can find out in how much this expectation is correct. For example, it might different if there are lots of hills in the area, or if for some reason one is often changing speeds.
In any case, I don't think that average driving is very relevant for calculating range. The exception being if you can't charge each night, and actually want to do a lot of average driving.
