The cost of the intractable semiconductor shortage has ballooned by more than 90%, pushing the total hit to 2021 revenue for the world’s automakers to $210 billion.

That’s the latest dire forecast from AlixPartners, which predicted global automakers will build 7.7 million fewer vehicles due to the chip crisis this year. That’s nearly double the consultant’s previous estimate of 3.9 million in lost production. Despite ongoing efforts to shore up the supply chain, semiconductor availability has worsened as automakers exhaust stockpiles and other industries have no more to spare.

"The barrel is empty, there’s nothing left to scrape,” Dan Hearsch, managing director of AlixPartners automotive and industrial practice, said in an interview. "Going forward, sales will suffer. Sales hadn’t suffered because there was enough inventory to draw from. It’s not there anymore.”
