GM's new soft-pack battery is supposed to be cheaper than Tesla, with a longer range.
2.5% more range, it does not say how much cheaper, just that traditionally polymer shells were more expensive, but up to 40% lighter. Wikipedia says a Tesla battery pack is 1,200 pounds.
480 pounds is a lot of weight savings, only 12% of the weight of a Model 3, but 12% weight savings in a vehicle is awesome. https://www.popularmechanics.com/sci...hicle-battery/
