That is correct. Most car manufacturers currently pay way more than $100 per kWh battery capacity. Also, the electrical vehicles are made in much smaller numbers than combustion engined ones, raising production costs considerably. But for a long-term calculation, you cannot ignore the cost savings of leaving off all the combustion-related technologies. And that there are significant cost savings should be obvious.
