For much of last year, established automakers like General Motors and Ford Motor operated in a different reality from Tesla, the electric car company.
G.M. and Ford closed one factory after another — sometimes for months on end — because of a shortage of computer chips, leaving dealer lots bare and sending car prices zooming. Yet Tesla racked up record sales quarter after quarter and ended the year having sold nearly twice as many vehicles as it did in 2020 unhindered by an industrywide crisis.
Tesla’s ability to conjure up critical components has a greater significance than one year’s car sales. It suggests that the company, and possibly other young electric car businesses, could threaten the dominance of giants like Volkswagen and G.M. sooner and more forcefully than most industry executives and policymakers realize. That would help the effort to reduce the emissions that are causing climate change by displacing more gasoline-powered cars sooner. But it could hurt the millions of workers, thousands of suppliers and numerous local and national governments that rely on traditional auto production for jobs, business and tax revenue.
Tesla and its enigmatic chief executive, Elon Musk, have said little about how the carmaker ran circles around the rest of the auto industry. Now it’s becoming clear that the company simply had a superior command of technology and its own supply chain. Tesla appeared to better forecast demand than businesses that produce many more cars than it does. Other automakers were surprised by how quickly the car market recovered from a steep drop early in the pandemic and had simply not ordered enough chips and parts fast enough.
G.M. and Stellantis, the company formed from the merger of Fiat Chrysler and Peugeot, all sold fewer cars in 2021 than they did in 2020.
Tesla’s production and supply problems made it an industry laughingstock. Many of the manufacturing snafus stemmed from Mr. Musk’s insistence that the company make many parts itself.
Other car companies have realized that they need to do some of what Mr. Musk and Tesla have been doing all along and are in the process of taking control of their onboard computer systems.
Mercedes, for example, plans to use fewer specialized chips in coming models and more standardized semiconductors, and to write its own software, said Markus Schäfer, a member of the German carmaker’s management board who oversees procurement.
