Porsche could introduce four-cylinder engines to cut CO2 emissions

Article by Christian A., on October 18, 2010

As you may know already, Porsche is counting on hybrid drive cars in order to reduce its fleet CO2 emissions and it plans to introduce e hybrid version on each of its models (you can read all about this here).

Earlier this year, Porsche launched its first hybrid vehicle, the Cayenne S Hybrid. The next hybrid vehicle will be the Panamera S Hybrid, which will use the same technology found on the Cayenne.

The production version of the 918 Spyder a.k.a. Porsche’s first hybrid supercar will be introduced within the next four years. Porsche is also planning hybrid versions of the 911, Boxster and Cayman.

According to European Union, Porsche needs to reduce its CO2 emissions to 216 grams per kilometer by 2015 (current limit is 255 g/km). Now here is the big surprise: the German manufacturer could introduce smaller engines in order to cut CO2 emission.

"If the CO2 guidelines require it, then our engines will become smaller and may have just four cylinders," development chief Wolfgang Duerheimer said. “The important thing is that the performance has to be right. The 911 must always be on the cutting edge.”

This means that with using turbocharging and direct injection, Porsche could transform a modest four-cylinder powerplant into a sports car engine.

Furthermore, the weight of Porsche’s upcoming sports cars will drop significantly, as the manufacturer is developing carbon car bodies for road vehicles. [via autonews - sub. required]
