Tesla puts 4680 battery cells back in Model Y; Here’s why
Tesla has started building Model Y battery packs with its in-house 4680 cells again, more than two years after pulling the plug on the original 4680-equipped Model Y to prioritize Cybertruck production.

The announcement came on January 22, just days before a major ice storm hit Austin and, conveniently, less than a week before Tesla’s Q4 2025 earnings report today.
The service has started back since then, but no one is getting the “unsupervised” rides.
