DETROIT >> Ford Motor Co. plans to build a new $1.6 billion auto assembly plant in Mexico, creating about 2,800 jobs and shifting small-car production from the U.S. at a time when moving jobs south of the border has become a major issue in the U.S. presidential campaign.

The company announced the plant in the San Luis Potosi state Tuesday without saying specifically what cars it will build there. But the United Auto Workers union has said Ford plans to shift production of the Focus compact and C-Max small gas-electric hybrid from suburban Detroit to Mexico, where the cars can be made at lower cost and more profitably.

The UAW's new four-year contract with Ford, signed last year, guarantees new vehicles for the Wayne, Mich., assembly plant and a $700 million investment that preserves the plant's 3,924 jobs. Union members have said they expect the factory to get a new version of the Ranger small pickup and a small SUV called the Bronco.

Ford announced the Mexican plant on the day of the key Wisconsin primary. Republican front-runner Donald Trump has railed about corporate America moving jobs to Mexico to take advantage of what he calls a lopsided trade deal. He has vowed to rewrite the 1994 North American Free Trade Agreement, tax imports and punish U.S. companies including Ford.


In response, the automaker has highlighted its investments in the U.S. At the New York auto show in March, CEO Mark Fields said Ford spends more than 80 percent of its capital in the U.S. and has committed to spending another $8 billion to $9 billion in the next four years.

"Since 2011 we've invested over $10 billion in our facilities. We've hired over 25,000 people" in the U.S., Fields said.

Auto and other manufacturing jobs having been moving south for years. Mexican auto production more than doubled in the past decade, and the consulting firm IHS Automotive expects it to rise another 50 percent to just under 5 million vehicles by 2022. U.S. production is expected to increase only 3 percent, to 12.2 million vehicles, in the next 7 years.

Joe Hinrichs, Ford's president of the Americas, said Ford is a global company that builds cars where it makes the most financial sense. He confirmed new plant would build small cars starting in 2018. "We've talked about improving our small-car profitability and this is an important part of that," he said Tuesday in an interview with The Associated Press.

Under the new UAW contract, Ford factory workers get about $60 per hour in wages and benefits, while auto workers in Mexico average about $8 per hour, according to the Center for Automotive Research, a Michigan industry think tank.

Trump began criticizing Ford last summer after the company said it planned to invest $2.5 billion in engine and transmission plants in Mexico. Hinrichs said the timing of Tuesday's announcement had nothing to do with the presidential race.

Trump hasn't only targeted Ford. He has pledged to give up Oreos after Nabisco's parent, Mondelez International, said it would shift production from Chicago to Mexico.
