I have spotted a reference on TOB, initially I though, it is some sort of rubbish, but after finding/reading the article, it looks like something to consider – basically GM is testing a battery chemistry, which is going significantly reduce the cost of batteries and bring 400 miles range to the “low end” segment of car segment, and $30k “medium” EV. Considering, that this is not Tesla (ie the provided information is more relevant and quite probable), this may have some implication to the industry as well as to LAC.
