Performers unveil the new Ford Taurus flagship model at a media event ahead of the Auto Shanghai show in Shanghai, Saturday, April 18, 2015. Chinese auto brands, pressed by foreign competition, are enjoying a rebound as they head into next week's Shanghai auto show, their biggest marketing showcase of the year. This revived momentum in turn adds to pressure on General Motors Co., Volkswagen AG and other global brands that see China's crowded market as their future at a time when sales growth is slow in the United States and stalled in Europe.Ng Han Guan/The Associated Press
