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 will propose this week that the European Union lower its tariff on U.S. car imports to 2.5% from 10%, in line with the current U.S. import tariff, the German automaker's CEO Oliver Zipse said on Tuesday.

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.

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.

The EU imposed anti-subsidy tariffs of 7.8% on Tesla on top of the 10% levy. BMW’s imports were hit with a 20.7% duty. The firm was hit because its electric Mini Cooper and the 100% electric Mini Aceman are made in China, according to car website Autogear.
