Porsche officials are exploring the possibility of adding diesel variants to the company's North American lineup to help meet the growing demand for fuel-efficient cars. On sale in Europe since early 2009, the Cayenne diesel could be one contender for the job and may be followed by the Panamera with a diesel engine and a gasoline-electric hybrid powertrain.

“We are discussing internally if we should introduce the Cayenne diesel in the U.S. this year. Also a Panamera diesel is an option”, said the brand's sales and marketing chief, Bernhard Maier.
