GENERAL MOTORS JUST ROLLED OUT A CAR that's perfect for the moment. It's the 2027 Chevrolet Bolt--a relatively cheap, all-electric subcompact that will let you drive right past gas stations, and dodge those high prices from the war in Iran.

But if you want a Bolt, you'd better act fast, because they won't be on dealer lots for long. GM has already confirmed that production will end next year. The plan is to convert the Bolt's factory in Kansas City back to manufacturing vehicles with internal combustion engines.

GM says it made its decision to limit the Bolt a while ago, and remains committed to producing other EVs. That's almost certainly true. But it's also true that GM has dialed back its overall EV ambitions--by, for example, shelving plans to convert more factories to EV production--and that other companies are doing the same. Just this past week, Honda announced it was scrapping plans for three EVs it had been preparing to manufacture at factories in the United States.

There's no single, simple explanation for the retrenchment. But a big part of the story is Donald Trump. Since taking office, he has launched an all-out assault on EVs--by working with Republicans in Congress to eliminate tax breaks for vehicle production and purchases, and by using his regulatory powers to gut federal and state emissions standards that favored fuel efficiency.

"It wasn't just the subsidies that Trump removed," Corey Cantor, research director at the Zero Emission Transportation Association, told me. "It was the fuel economy standards. It was the California regulations. So it was almost a triple whammy of policy pullback."

Trump has insisted that these old policies--the bulk of which were put in place by former President Joe Biden and the Democrats--were forcing the auto industry to make unprofitable vehicles, while sapping America of its petroleum-powered swagger. But high gas prices are turning that swagger into a stagger: Edmunds, the website for car buyers, says it has in recent weeks seen a rise in customer inquiries about EVs. You can safely assume that's going to continue as long as gas prices stay high, which means that more American consumers are going to be looking for vehicles that U.S. manufacturers are becoming less able to provide.

"We're going back to fossil fuel. I hope not too many of you people are going to be upset, but we have to go back to what works. We can't be foolish."
