Such plans would risk diluting the brand and alienate traditional customers, according to Mueller.

"We would do no good to the brand if we were to lose traditional Porsche customers" by pursuing a smaller Boxster model, the CEO was quoted as saying in an interview.

Mueller said Porsche also has no immediate plans to develop a smaller version of its four-door Panamera sedan, though he indicated that such a model could become an option in five or six years.

Porsche is aiming to increase annual deliveries to about 200,000 sports cars and SUVs by taking advantage of resources at Volkswagen. Europe's largest auto manufacturer owns 49.9 percent of Porsche's core business and is currently examining ways to purchase the remainder.
