Mueller said the sports car maker's German assembly plants in Zuffenhausen and Leipzig were too small for the brand to reach its ambitious sales goals. "We will consider this year whether to start production in Asia or North America," Mueller told the German magazine Focus in an interview.

Smaller than the Cayenne, the Cajun would be Porsche's entry-level model. The four-door Cajun crossover is supposed to enter production in 2013, followed by a two-door version in 2014.

Porsche could build the Cajun in China in a Volkswagen factory that produces the Audi Q5, which shares components with the Cajun, the magazine said.

Porsche also plans to open a customer center and test track in Shanghai near a Formula One race track, Mueller told WirtschaftsWoche. The brand will also expand its Chinese dealer network from 35 dealers to 85, then probably to 100, he said.

Porsche is being integrated into Volkswagen as the German automaker's 10th brand.
