&gt; Guess where we are now? I&#x27;ll calculate this for you. Tesla announced that their replacement batteries cost $12000 for the 85kWh version. That is $140&#x2F;kWh. Right now, in 2015, we are to the left of this entire diagram already.<p>Does the Tesla do 240 Wh&#x2F;mile? I searched quickly and saw 480 from someone, is there an official figure for this?
