When you say Porsche you think about six-cylinder engines. But now the company is considering a four-cylinder engine for the Cayman and Boxster models. The decision has been made in order to reduce fuel consumption and carbon dioxide emissions.
The announcement has been made by Klaus Berning who said that more economical versions of the Boxster and Cayman were on the way: "Clearly there is a trend to downsizing. We have to do everything possible within the brand limits to lower CO2 (carbon dioxide) emissions. [A four-cylinder] brings a lot of efficiency, so I will not exclude that, but if you ask me did we already decide one, no."
The same rule will not be applied to the 911 line-up because "911 is the core of the brand and follows different rules to the rest."
