PHYSIX OBSERVATION

By swapping CATL for its in-house system while still relying on Sunwoda for cell manufacturing, Li Auto is clearly aiming to seize control of the battery pack and BMS. For users, the short-term focus is delivery pace and consistency; the long-term question is whether in-house development can deliver cost and iteration advantages. This is another signal of new EV makers moving from integration to vertical in-house development.
