It happened very quickly — so fast that you might not have noticed it. Over the past few months, America’s Big Three automakers — Ford, General Motors and Stellantis, the oddly named company that owns Dodge, Chrysler and Jeep — landed in big trouble.

I realize this may sound silly. Ford, General Motors and Stellantis made billions in profit last year, even after a lengthy strike by autoworkers, and all three companies are forecasting a big 2024. But recently, the Big Three found themselves outmaneuvered and missing their goals for electric vehicle sales at the same time that a crop of new affordable, electrified foreign cars appeared, ready to flood the global market.

About a decade ago, America bailed out the Big Three and swore it wouldn’t do it again. But the federal government is going to have to help the Big Three — and the rest of the U.S. car market — again very soon. And it has to do it in the right way — now — to avoid the next auto bailout.

The biggest threat to the Big Three comes from a new crop of Chinese automakers, especially BYD, which specialize in producing plug-in hybrid and fully electric vehicles. BYD’s growth is astounding: It sold three million electrified vehicles last year, more than any other company, and it now has enough production capacity in China to manufacture four million cars a year. But that isn’t enough: It’s building new factories in Brazil, Thailand, Hungary and Uzbekistan, which will produce even more cars, and it may soon add Indonesia and Mexico to that list. A deluge of electric vehicles is coming.

BYD’s cars deliver great value at prices that beat anything coming out of the West. Earlier this month, BYD unveiled a plug-in hybrid that gets decent all-electric range and will retail for just over $11,000. How can it do that? Like other Chinese manufacturers, BYD benefits from its home country’s lower labor costs, but this explains only some of its success. The fact is that BYD — and Chinese automakers like Geely, which owns Volvo Cars and Polestar brands — are very good at making cars. They have leveraged China’s dominance of the battery industry and automated production lines to create a juggernaut.

The Chinese automakers, especially BYD, represent something new in the world. They signal that China’s decades-long accretion of economic complexity is almost complete: Whereas the country once made toys and clothes, and then made electronics and batteries, now it makes cars and airplanes. What’s more, BYD and other Chinese automakers are becoming virtually global car companies, capable of manufacturing electric cars that can compete directly with gas-burning cars on cost.
