SPRING HILL, Tenn. -- General Motors is revving up its Spring Hill plant, starting with a recall of hundreds of idled workers to build four-cylinder engines.
The automaker announced Friday that about 400 workers will be recalled to build the engines for mid-size crossover vehicles.
GM plans to invest $483 million to build the next generation of the company's Ecotec four-cylinder engine. The factory already builds three four-cylinder engines.
