1. That's kilowatt HOURS, not kilowatts, you ignorant, pitiful excuse for a journalist. (This is directed at the article's writer, not an you, Bruce.) 2. According to plugincars.com, the 2014 Spark has a battery capacity of over 20 kWh from 336 cells. So the cell count is down 43%, reducing assembly labor if not material cost. But so is the actual capacity. My guess is that GM are counting on the slight weight reduction to keep the range similar, but that they'll probably tweak the BMS to allow deeper discharges. This, if true, could marginally reduce battery life. They COULD have increased the battery capacity and extended the EV's range, and thus its appeal. However, it appears that they chose to take the extra profit on each vehicle instead. I wonder what Tesla would have done in a similar situation.
