Why Donald Trump is picking on GM and Ford

Donald Trump could have picked a better car to bash.

The incoming president lashed General Motors (GM) on Twitter recently for making its Chevrolet Cruze subcompact in Mexico. Whoops. The Cruze sedan—which accounts for 97.6% of all US Cruze sales—is actually built in Lordstown, Ohio. The slow-selling Cruze hatchback is built in Mexico, but annual sales of just 4,400 units are virtually negligible.

Trump went after GM just as cross-town rival Ford announced it was canceling plans to build a $1.6 billion factory in Mexico, as Trump has been urging the company to do since campaigning last year. Ford will still move production of its Focus subcompact from Michigan to Mexico, by ramping up production at another plant instead of building a new one. But it will also invest a fresh $700 million in Michigan, helping create 700 new jobs. Trump tweeted his approval.

The Ford news overshadowed Trump’s blunder regarding the Chevy Cruze, but Trump’s confusion on that is understandable. Automobiles are complex products that typically include components from all over the world. And most automakers sell their cars in dozens of countries, which means they have to base production decisions on a multitude of factors including consumer tastes, labor and material costs, exchange rates, transportation efficiency and where a given model is likely to sell the most. Hatchbacks aren’t popular in the United States, for example, but European drivers love them, which is part of the reason GM builds the Cruze hatch in Mexico—it can export from there to Europe with no tariffs, while the same car shipped from the United States would face a 10% levy.

Trump’s crusade to protect American manufacturing jobs has nonetheless put GM and Ford (F) in the crosshairs, and other automakers might be next. Trump targeted Ford during last year’s campaign because of news the company was opening a new factory in Mexico, to build the Focus subcompact. On another matter, Trump took credit for persuading Ford’s Lincoln division to keep producing its MKC crossover at a plant in Kentucky instead of moving it to Mexico, although Ford had merely been planning to adjust production, not move work permanently out of the country.

The most ‘American’ cars

Trump has now extended his campaign against the automakers to GM, though he could just as easily have targeted Fiat Chrysler, Honda, Toyota or Volkswagen. Virtually every global automaker assembles cars in Mexico, as this map from the Center for Automotive Research shows:
