AFP/Getty Images Porsches and other European-made cars could be hit with higher tariffs unless trade barriers come down, President Trump has threatened.President Donald Trump is continuing to threaten Europe with stiff tariffs on auto imports if they don’t drop unspecified trade barriers, but the risk might not be worth the reward. Relatively few European-made cars are actually sold in the United States, for one thing. And even if Trump were to get his way, Europe wants something in return: Easier access to the highly protected and lucrative market for SUVs and pickup trucks that generate the bulk of profits for American auto makers FordF, -0.99% and General Motors GM, -1.34% . Trump on Sunday said he sees his threat to impose global auto tariffs as his biggest weapon to extract concessions from trading partners, adding the European Union “is possibly as bad as China” in hindering U.S. trade. “They send a Mercedes in; we can’t send our cars in,” he said.via
