China sales top 20 million

New-vehicle sales in China passed a milestone in 2013: 20 million units.

Including buses and trucks, the market climbed 14 percent to 21,984,100. Sales of light vehicles, including sedans, SUVs, pickups and microvans, rose 16 percent to 17,928,900.

LMC Automotive forecasts a 13 percent increase in light-vehicle sales in 2014 -- which would put the category over 20 million -- and a 9 percent increase in 2015. But IHS Automotive recently cut its light-vehicles forecast for 2014 from a 10.7 percent increase to 9 percent.

That's because one city after another is slapping limits on new-vehicle registrations to reverse worsening traffic congestion and air pollution. In December, the port city of Dalian in northeast China approved a plan to curb sales of new cars. It is the fifth city in China -- along with Beijing, Shanghai, Guiyang and Guangzhou -- to restrict vehicle sales, and others are expected to join them.
