Chevy Bolt that has a 60kWh battery is going to be sale soon. The price is quite cheap: $38,000 before any tax credits. I believe this price is doable because the battery price will be in half. Presumably, the same story is for Model 3. Given such cheaper battery price projection, I'm wondering whether the prices of Model S and Model X could be also reduced. What is the current price of the battery pack of Model S and Model X?
