DETROIT — Porsche AG is considering whether to offer a hybrid-powered version of its Cayenne sport/utility vehicle and plans to decide whether to pursue the option later this year, its chief executive said Jan. 10, according to the Associated Press. Wendelin Wiedeking told reporters at the North American International Auto Show that a hybrid drive would only make sense in its Cayenne, since space and weight considerations would stand in the way of a hybrid 911 or Boxster. "Since we at Porsche are convinced that environmental compatibility will be the most significant success factor for the future of the automotive industry," Wiedeking said, "our engineers have been looking closely at this alternative technology for a long time." Wiedeking said Porsche also may decide later this year whether to add another model series to its current lineup.
