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.
But this time, the motivation isn’t revolutionary battery tech. It’s tariffs. And also, Cybertruck’s poor sales mean the program doesn’t consume many batteries.
