Diesel Cayenne in 2009

Porsche decided diesel is the future, thereby the company will introduce a diesel-powered car by the middle of 2009, and probably this first car will be the Cayenne SUV. Decision came to save substantial development costs.

Porsche CEO Wendelin Wiedeking has said repeatedly that the company constantly evaluates the commercial feasibility of putting a diesel engine in one or more of its models.

A Porsche spokesman said Friday that the issue remains under discussion internally. Porsche sources said no decision has been made.

Porsche, which currently uses only gasoline engines, has decided to introduce a hybrid version of the Cayenne in 2010, AID said. Whether hybrids will power other Porsche models depends on whether new technology will make it possible to substantially reduce battery size.
