China's passenger-vehicle market had its strongest start since 2010, indicating auto demand is thriving relative to other industries at a time when broader indicators are slowing in the world's second-largest economy. Wholesale deliveries of cars, multipurpose and sport-utility vehicles rose 20 percent to 2.84 million units in January and February, up from 2.37 million units a year ago, according to the China Association of Automobile Manufacturers. While sales in the world's biggest car market fell last month because of the Lunar New Year holiday, they beat the average estimate of five analysts surveyed by Bloomberg by 11 percent.
