General Motors is close to approving a massive investment at its Oshawa, Ontario plant, where the automaker is expected to build its Zeta platform vehicles, such as the Chevrolet Camaro and Impala, reports the Globe and Mail. Currently, the plant No. 2 is scheduled to close in 2008, but the investment could save 2,500 jobs and turn the plant into a 505,000-car-a-year powerhouse. “I don’t think there’s any question that Zeta will happen there,” an industry source who is familiar with GM’s product plans said. Sources say the new retro-styled Chevrolet Impala will be first out of the chute in June, 2009. Next comes Camaro in September, 2009, with annual sales projected at 100,000 a year, including a convertible version of the muscle car. The two Chevrolet models will be followed by the Cadillac DTS sedan in June, 2010, and the Buick Lucerne in October, 2010. Previous reports suggested the Buick model would be called “Statesman.” GM’s Bob Lutz also recently said a new Pontiac GTO and a Chevy Monte Carlo will be build on the Zeta architecture.
