I recall reading somewhere, that one of the reasons for the Volt's abysmal range performance is at least in part due to GM's decision to limit battery usage and charging to within the 25% to 85% range, resulting in only using 60% of cell capacity. With such a conservative usage profile, the batteries should provide more cycles of usable lifetime, can be re-charged more quickly, and address "bricking" and combustion concerns by using LiFeP04 battery chemistry.

Looking at miles of a range versus cost .. that makes the Volt more expensive than the Tesla "S". Certainly I want all the commercial production EV's to be successful in the marketplace, but even first adopters are gonna look at price/performance when making the jump to an EV. Telsa, Nissan, and GM are all using different battery chemistrys' .. Let the Games Begin
