With demand for its new Fusion surging, Ford has started additional production of the popular midsize car.
1,400 workers and a second shift at the automaker's Flat Rock assembly plant just outside of Detroit are enabling Ford to ramp up supply of a car that has helped the company post its strongest U.S. sales since 2006.
This year, Ford sales in the U.S. have climbed 12.9 percent, outpacing the industry as a whole, which is up 8.5 percent, according to AutoData.

Meanwhile, Ford's market share is up 0.6 percent to 16.2 percent, placing the automaker within 2 percent of General Motors, which has been the top selling automaker in the U.S. for decades.
Fusion gaining on Asian models
With Fusion sales up 13 percent this year, Ford finds itself wrestling with tight supply of a car it re-designed for this model year. In fact, in some parts of Florida and California, Ford is down to 12-16 days' supply of certain Fusion models.
