The head of Ssangyong Motor Co., South Korea's fourth largest carmaker, said Tuesday that the mass production of its XLV sport utility vehicle (SUV) will start late next year. Lee You-il said the seven-seat concept version of SUV shown for the first time at the Geneva International Motor Show is scheduled to reach consumers after Ssangyong releases its X100 compact crossover utility vehicle (CUV) in early 2015.
