China may surpass US as Porsche's largest market this year thanks to Cayenne

China has already surpassed the United States as the world's largest automotive market, so it's no surprise that one day soon it will be the world's largest Porsche market.

In fact, that day may already be here, as the PRC's Porschephiles outbought their American counterparts in September. Porsche's Chinese dealers sold 4,344 cars last month to America's 3,607. Through all of 2014 so far, though, the US is still the larger market for the German brand.

"The U.S. performed very well this year, after a great year in 2013, but China is growing fast, thanks to theCayenne which is our best seller there," Porsche's sales and marketing boss, Bernhard Maier, toldAutomotive News Europe.

"It is still an open head-to-head race," Maier said of the China-America competition. We'll be interested to watch how this one plays out over the next three months.
