i think Tesla is really breaking ground with those new cells with a capacity of 245wh/kg. Others use 140wh/kg. Thats a huge increase. So why doesnt use Audi,GM or whoever use those cells, say go in partnersip with Panasonic to build new factories. I think this is really the event horizon for e-cars. 200kilos for 49kwh is really big and with a car that weighs only 1300kg(golf) you could go really far(400km). I mean you could certainly build now a e-car weighing only 1300 kilo. the whole propulsion system in a ICE car weighs around 300-400kg. Why isnt this happening?
