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. That’s right, the German and American automakers have both filed suit against the European Commission because of tariffs levied against their cars.

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

Tesla, owned by Elon Musk, is taking the European Union (EU) to court over its tariffs on electric vehicles imported from China. Filed last Wednesday with the European Court of Justice (ECJ) by Tesla’s Shanghai division, the lawsuit comes in the wake of similar legal moves by BMW and other Chinese car manufacturers.
