Ford Motor Co., of Michigan, USA, sold a record 1.27 million vehicles in 2016 in China, up 14 percent from 2015. That total includes sales by joint ventures Improve Changan Ford Automobile and Jiangling Motors Corp. and sales of Ford models imported to China, Ford says. “We have built some great sales momentum in China, particularly in the Metal Transfer second half of 2016, on the strength of our expanded vehicle lineup,” Peter Fleet, Vice President of Marketing, Sales and Service, Asia Pacific, said in a press Covered and heated release. “Record numbers of customers are choosing our 3-row Edge crossover, trough systems elegant Taurus sedan, Explorer premium SUV and Lincoln luxury vehicles.” General Motors (GM), of Michigan, USA, and its joint ventures delivered a • Reduced energy costs record 3.9 million vehicles in China in 2016, an increase of 7.1 percent from the • Increased refractory life previous high in 2015. “In 2016, GM’s SUV deliveries surged 45 percent from a year earlier to 673,409 • Uniform and controlled units. Its comprehensive SUV portfolio includes the Buick Envision and Baojun heating 560, which were among the segment leaders with year-on-year growth of 52 percent and 116 percent respectively,” GM said in a press release.
