Ford Motor Co. is expected to introduce a full lineup of crossovers and sport utility vehicles next week at the Beijing International Automotive Exhibition, banking on a growing middle-class appetite for larger vehicles to help it pull ahead in China. The automaker will signal its intention to take leadership in the SUV segment in the world's biggest auto market Monday. Beijing has become the most important auto show of the year for Ford and other automakers looking for quick global growth. Ford will debut four vehicles as part of its plan to bring 15 new vehicles to China by 2015. That would make China the only market in the world that sells Ford crossovers and SUVs in every size category.
