 It's being called a potential watershed moment for Europe's biggest carmaker, and not the good kind. Volkswagen is considering closing an Audi electric vehicle plant in Germany. The company has never closed a car factory in the region, but the pricey site could become the first due to poor demand for an electric SUV produced there. Carmakers have been grappling with waning EV sales, prompting a range of companies from Ford to Mercedes-Benz to rethink plans. On Wall Street, futures are slightly higher.
