Carmakers have already lost out on making hundreds of thousands of vehicles in the opening months of this year, with most large manufacturers announcing stoppages to production that analysts expect to cost the industry billions of dollars over the course of the year. The crisis, which began last year but was exacerbated by the Texas storms and a fire at a Renesas chip factory in Japan, comes just as manufacturers were banking on a recovery in demand after the pandemic. Griffiths, who took on the role last October, said that production at Seat’s Martorell plant outside Barcelona was currently “hand to mouth”, with the brand deciding which cars to build only after it receives chips from suppliers.
