On the Tesla Founders blog, I asked, "Is the range of your car then higher than the currently stated range of 244 miles? Or is the range the same but total battery capacity higher in order to have shallower discharges? Do you know when the switch to 2400 mAh done?Sorry if the barrage of questions is rude…" And.... "Martin sez: As far as I know, every production Tesla was made with 2400 mAh cells. These are the current “jelly bean” cells, and where the majority of the world’s production is. I am also pretty sure that the final range numbers as reported by Tesla were achieved with a pack that used 2400 mAh cells." So I guess the mAh of the battery pack is unrelated to whether it is powertrain 1.5 or powertrain 1.0. And I guess the range has been finalized too.
