There is no mystery here - the charge/discharge/lifespan characteristics of LiIon batteries are pretty well known at this point. GM is doing this to try to preserve the life of the battery over time rather than go for range. The testers were unable to do so during their brief testing but I would be almost certain that the algorithm for battery usage would shift as the battery ages in order to shield the consumer from being aware of battery capacity decrease.

Perhaps after experience is gained, a software update could allow wider use of battery capacity for longer EV range and better hybrid performance.

Seems like the need to only use the 'middle, of the battery is a real issue. You carry around 375lbs and only 'need' 1/2 of it? Like an extra passenger in the car all the time. What can be done to improve battery characteristics?
