General Motors, which in 2013 was outsold by Volkswagen AG in China for the first time in nine years, has been reorganizing brands to give more focus to its global offerings. The Detroit-based carmaker said in December that it will pull the Chevrolet marque out of Europe, where GM is trying to restore profit at Opel and U.K. sister division Vauxhall, and that its Holden unit will stop producing cars in Australia.
