I would also like to see proper metrics such and KWH/KG. However, I believe there is an optimum ratio for battery size to vehicle size. To gain more range, you will need more volume of batteries. at a certain point, you will need to sacrifice passenger space, vehicle size, weight, or aerodynamics. the more batteries, the more weight. currently that ratio seems to be optimum for a 200+ to 300 mile range. yes the title of the article has been dumbed down and vague, but it gets the point across to the general masses that a more energy dense newer technology is on the horizon. what else to you expect for Click-Bait.
