This means Tesla will have 4680 at reasonable scale and car ready in 2021. This is not the 12-18 month timeframe from the last earnings call. This means not 11-17 months from today but less than 7 months. This is also confirming Texas production later this year.
Texas will also have front and rear gigacasting.
The 4680 cells means the Model Y from Austin will have the structural battery. The front and rear casting will massively reduce cost and weight. There will also be weight reduction from the structural battery. These all combine for a lighter, lower cost and longer range vehicle.
Having large-scale 4680 cells will mean Tesla will have the battery supply for Cybertruck and Semi products at scale in 2022.
