WASHINGTON (Reuters] – Twelve senior executives of major automakers around the world urged two U.S. senators from California on Friday to block a plan to grant union-made electric vehicles an additional $4500 tax credit.

These automakers also include Toyota Motor (NYSE:) Corp, Volkswagen AG (OTC:), Hyundai Motor Co and BMW AG, which said in 2020 they collectively employed over 9,000 California residents and generated $19.7 billion for the state’s economy, asked Democratic Senators Dianne Feinstein and Alex Padilla in a letter seen by Reuters “to oppose any federally funded EV consumer incentives that do not treat California’s auto workers as equal to every other American auto worker.”
