Summary: Jan. 15 (Bloomberg) -- Detlev von Platen, chief executive officer of Porsche SE's North American unit, says "German manufacturers like Audi have proven that the diesel engine is a very efficient and clean technology," which was a reason for Porsche to put a diesel engine in the Cayenne. Von Platen talked with Bloomberg's Pimm Fox and Vonnie Quinn on Bloomberg Radio's "Taking Stock" on January 14, 2013, broadcasting from the North American International Auto Show in Detroit.
