As China is poised this year to surpass the U.S. as the world’s largest economy based on purchasing power, recent Porsche AG sales figures suggest that China could be on its way to becoming the German luxury automaker’s biggest market.

The Stuggart-based maker of the 911 Carrera attributed the success in China to its best-selling Cayenne crossover, which this year received minor refreshments to its exterior design and new powertrain options.

“China is growing fast,” Bernhard Maier, Porsche’s head of global sales, told Automotive News Europe from the Paris Auto Show. “It is still an open head-to-head race [if China will beat the U.S. in 2014 Porsche deliveries]."

“The new [2015] Cayenne will provide further stimulus for growth during the next few months and support our qualitative growth strategy,” Maier said in the report published Thursday, when last month’s global sales figures were released.
