Different bets
What were these carmakers betting on?
Tesla bet on charging and built a network. Rivian and Volkswagen shared platform engineering. CATL offered an integrated chassis. Established US carmakers built software teams. These companies acted on different views of what would constrain electric vehicles.
What this covers. Tesla, Rivian, Volkswagen, CATL, selected US carmakers and Chinese regulators. Evidence depth differs by case and rests on roughly one detailed account per company. No measured comparison ranks the strategies, and none establishes that any bet was correct.
Follow this pathway on the map →-
Tesla built its own charging network to improve long-distance use for Tesla customers.
Owning the network and standardising the connector were separate decisions.
-
Tesla released the connector specification while retaining ownership and operation of the charging network.
Other companies shared larger integrated systems while preserving an owner for the platform.
-
Rivian and Volkswagen announced a shared platform through a joint venture. CATL offered a supplier-owned chassis. Neither created an open module market.
Sharing a platform bought capability, while some carmakers chose to build critical software capability internally.
-
US carmakers created internal software and automated-driving teams because they retained responsibility for vehicle behaviour.
Those organisational choices were voluntary. Chinese supplier rules narrowed the choices available to carmakers.
-
Chinese market-access rules influenced which battery suppliers a carmaker could use.
Regulation can also make a technically available feature unattractive by changing who carries legal responsibility.
-
Some carmakers declined Level 3 automated-driving features that would have increased manufacturer responsibility, even while offering more capable driver assistance.
Across these different choices, the carmaker remained responsible for the finished vehicle.
-
None of the strategies transferred complete vehicle specification, integration and finished-product responsibility away from the carmaker.
Compare each company by what it decided to own, what it depends on and what it answers for. Then hold the awkward fact beside it: over the same years, the serious producers moved their boundaries in the same direction. Whether the bets caused the outcomes, or whether one common pressure produced both, is not settled by anything here.
