After 100k Miles EPA Range will be at
Tesla at 85%
Car buyer need to know this.
Unfortunately, your proposed info will not be right for MANY folks. At 100K miles with the 4/2013+ to model year 2014 pack ("wolf pack" as Leftie calls it) and probably the "lizard" pack for someone in the mild Pacific NW or Portland, OR doing that within say 3-6 years, those folks will probably have 75 to 80%+ (wild guess based upon when I've seen folks in the PNW lose their bars) EPA range.
Someone in Phoenix w/the same number of miles and the same amount of time w/the "wolf pack" will probably have like 45% or less.
And, if it were the typical 12K miles/year, on the "wolf pack" I'd guess the PNW might have 70+% while the Phoenix person would have maybe 20-30%.
It's not the mileage only. It's a combination of calendar losses, climate and cycles.
