I'm aware of promises of improvements related to the 2170 cells, which were delivered first in model 3 allowing lower prices and range of 300+ miles. Then a rev to the model S/X allowed for range and performance increases. Before the 3 the competition claimed sure the model S is an amazing car, but can Tesla actually produce an under $50k car to reach the wider luxury market. There's a pending 4680 improvements widely expect to ship in the Texas gigafactory model Y this quarter, time will tell. I believe this is generally on the announced schedule. Am I missing something? Tesla batteries seem to be delivering on promises and experts in the area seem impressed with the Tesla battery reliability, performance, longevity, and kwh/$. Some to the point of calling Tesla a hugely successful battery company that includes various packaging for their batteries in the form of power walls, and model 3/y/x/s.
