Good point, MyDesign. I can see that hybrids will continue to improve and continue to come down in price. They will come down in price partly because of increased volume over the next decade and because of competition. I can't see this path for EVs.
Engineers from both Ford and GM have told me they expect the cost of lithium-ion battery packs to dip to $250/kWh some time after 2020. If that's so, it would probably cut about $8,000 out of the price of a Volt battery. That would be a huge boost for the Volt and for every plug-in hybrid, especially those with larger batteries.
Cost is a major factor, ChasChas. Automakers are expecting a lot out of their customers. They're expecting customers to buy a car with limited performance and high costs. And as Chuck mentioned, these cars may have low resale value if they need a new battery.
