There’s been considerable talk lately of a tariff war brewing, but some shots have already been fired by the European Union with both Tesla and BMW in turn suing.

BMW said in a statement that EU duties on battery electric vehicles “harm business models of globally active companies.”

Tesla and Germany’s BMW are suing the European Commission, joining a growing band of Chinese automakers to oppose the European Union on its punitive tariffs on electric vehicles.
