According to the EPA, the Tesla S is rated for 265 miles range (85Kwh battery).
However, the same EPA sticker info says that Model S consumes 38 KwH/100 miles of driving (average city and highway), which seems high but is obviously based on some testing methodology that must build in AC usage, wind, etc.
At 38 Kwh/100 miles, my 85Kwh battery would give me only 223.7 miles of rated range, so the "EPA Rated 265 mile range" must come from some other consumption data/method. Can anyone shed light on this? I am only interested in how the EPA came up with the 265 mile range number; I realize that the 38 Khw/100 miles number is far above most folks average usage.
I did find this link to a detailed excel file: http://www.fueleconomy.gov/feg/epadata/12data.zip . However, I could not find any energy consumption numbers that match up to the 265 rated range. Further, that data file raises another question: according to the EPA data file, the battery is 350 volts and has a capacity of 237 amp-hours. That would seem to equate to 82.95 Kwh of capacity. Not to be nitpicky, but 82.95 Kwh is less than the advertised 85Kwh (and charging an extra 2 Kwh at an RV park at 30 amps takes 20-30 minutes so not inconsequential). It could be that there is a 2Kwh reserve, but that would seem inconsistent with the conclusion reached in other threads that the rated mileage/consumption includes the reserve. Or is it just that "P85" sounded better than "P83"?
Also, does anyone have a link to the actual report where the testing of the Model S specifically is detailed? I am interested in how the EPA measured the consumption and range (e..g, did they run it on a dynometer until the battery was bricked? rely on the Model S onboard energy reporting app? use some other direct measurement of battery consumption?)
