While GM will still sell cars like the Cruze sedan in parts of Southeast Asia, an emerging markets battleground for global automakers, it is shifting focus to push the ‘American heritage’ of its SUVs and pickups such as the Trailblazer and Colorado. The restructuring – under Executive Vice President Stefan Jacoby, who oversees markets beyond the Americas, Europe and China – marks a retrenchment in Asia by the U.S. automaker. While business grows in China, the world’s biggest autos market, GM has struggled in other parts of its international operations unit, which doesn’t include China.
