The No. 2 U.S. automaker, however, did not reveal where it plans to build a new, low-cost manufacturing facility. A leaked Ford document had suggested that the automaker is looking to build the plant in Mexico.

Ford's intent to build the facility was announced in January as part of the company's restructuring plan dubbed Way Forward.

"We remain committed to a new low-cost manufacturing facility. But we have made no decisions on where it will be located," Mark Fields, the executive vice president in charge of Ford's North American restructuring effort, said in a statement.

"The key to success will be high quality and low cost and that certainly can be in the U.S., Canada or Mexico," he added.

A leaked copy of a confidential Ford document, obtained by a Michigan newspaper this week, showed that Ford is preparing to invest up to $9.2 billion over the next six years in Mexico to leverage its low operating costs there.

Ford did not reveal the investment involved in upgrading the plants. The automaker has called the leaked report "speculation."

"The dollar amounts are incorrect," Ford spokesman Said Deep said, declining to comment further on it.

Under Ford's restructuring plan, the automaker plans to close 14 plants and cut up to 30,000 hourly workers in North America.

Ford, which is struggling with rising costs and declining U.S. market share, said it will upgrade assembly plants in Cuautitlan and Hermosillo, as well as its engine plant in Chihuahua.
