At a technical briefing on the new Porsche Panamera this week in Germany, Wolfgang Dürheimer, EVP of Research and Development at Porsche talked about additional powertrains and CO2 reductions. On the question of downsizing engines for its cars, Dürheimer said that there were no current plans for smaller displacement conventional engines in the Panamera than the 4.8-liter V8. In certain markets, such as China, where larger engines are taxed more heavily, Porsche may choose to offer a smaller engine. The company also has not decided whether to install the 3.0-liter V6 diesel that recently launched in the Cayenne into the new four door.
Porsche will, however, introduce its hybrid system in the Panamera after it debuts in the Cayenne next year. Porsche is working on a variety of technologies, some of which have already been implemented, to reduce CO2 emissions. The V8s in the Panamera and the flat-6 in the 911 already have direction injection and those vehicles are also available with dual clutch gearboxes.
Dürheimer promised that Porsche would reduce its CO2 emissions by 25 percent by 2012 in line with the new EU regulations. Moreover, the company would do so without pooling its fleet with Volkswagen or any other brand. It intends to meet the rules on its own and without resorting to tactics like flex fuel capability.
