China plans to restrict vehicle sales in eight more cities to curb traffic congestion and pollution, but car manufacturers are not worried, since they expect organic growth in the world's biggest auto market to outweigh any restrictions.
And, environmentalists say, any such measures are unlikely to make much of a dent in air pollution.
New car sales are already restricted in four Chinese cities - Beijing, Shanghai, Guangzhou and Guiyang - by limiting the number of license plates and selling them to consumers through auctions and lotteries.
Last week, the China Association of Automobile Manufacturers said eight more cities, such as Chengdu, Chongqing and Wuhan, might soon join Beijing and Shanghai in restricting new car purchases. Government officials have still not spelled out the policy.
Shi Jianhua, the auto association's deputy secretary general, warned that such restrictions, if implemented, could cut sales by 400,000 vehicles, equivalent to 2 percent of domestic sales in 2012.
Industry insiders and experts say the additional restrictions, also likely to be implemented by limiting license plates, will not depress overall sales in China.
"We expect licensing restrictions to have limited impact on new car sales," Bob Socia, head of China operations for General Motors Co.(GM.N), said in an e-mailed statement to Reuters, referring to such fears.
Experts say any dent the curbs are likely to deal on sales would be more than made up by growth elsewhere in China's vast market, as wealth spreads to smaller, so-called lower-tier cities.
Those cities are smaller compared to Beijing, which has 20 million people, but are still populous by standards in Europe and North America. For example, Wuxi, just west of Shanghai, has a population of around five million people.
In places like Beijing and Shanghai, GM's Socia said new car sales are going to become increasingly less important, as the market begin to mature. More important will likely be replacement sales by consumers buying new cars using existing license plates, he said.
"If all 25 cities with severe traffic situations in China were all to implement restrictions in 2015, we estimate that the impact to GM car sales would only be about 2-3 percent," Socia said.
SMALLER CITIES
According to a report published last week by marketing research firm Nielsen, nearly 70 percent of China's prospective automobile buyers in the next 12 months are likely to come from Tier 3 and Tier 4 cities, which are home to roughly half of China's total number of car buyers today.
