SAIC General Motors Co Ltd, a joint venture between China's SAIC and General Motors, plans to unveil a new production line for its fuel-efficient SUVs in the first half of 2017, company sources said on Sunday. The facility, constructed in China's central industrial city of Wuhan, will be able to produce 360,000 vehicles a year, bringing the combined capacity to 600,000 for SGM's Wuhan plant, one of the company's four major manufacturing bases in China. SGM said it has invested 7.5 billion yuan ($1.1 billion) in the new production line, which has been under construction since January 2015 and dedicated to producing a new generation of GM Chevrolet Equinox SUVs.
