It would not be the first time that automakers brought production of key components in-house. Many even have dedicated supplier subsidiaries which make metal fabrications, exhaust systems and assemble internal combustion engines. Ford, for example, has engine plants across the globe to support local manufacturing operations.

As with any case where confidential supply agreements are in place, it can be challenging to understand exactly what kind of deals around e-motors are being made. However, a
