One big loser in President Donald Trump's escalating trade war is likely to be the U.S. electric vehicle industry. Electric cars are already more expensive to make in the U.S. and more expensive for car buyers than vehicles that run on gasoline. As tariffs drive up all sorts of supply chain and production costs for automakers, they will have to prioritize making the cars that are most profitable. Those won't be electric. Automakers were already pulling back on ambitious electrification plans amid shrinking federal support and are strapped for cash on what is the less lucrative side of their businesses.
