U.S. consumers looking to get a tax credit on an electric vehicle purchase will have fewer models to choose from under new rules that limit the countries where automakers can buy battery parts and minerals. Only 11 of the more than 50 EVs on sale in the U.S. are eligible for the credits so far this year. The credits, which range from $3,750 to $7,500, are aimed at boosting EV sales as the Biden administration tries to cut planet-warming emissions.
