German magazine AutoBild is reporting that Porsche CEO Wendelin Wiedeking has finally confirmed that a diesel powered Cayenne will indeed appear in 2009. Porsche has long denied that would build a diesel powered vehicle because it would be out of character for the brand. This is of course a bogus argument since the Cayenne itself is out of character. We've previously seen spy photos of Cayennes being fueled at diesel pumps in northern Sweden. The Cayenne diesel get the same 3.0L TDI diesel V6 that's going into the VW Touareg and Audi Q7. The 240 hp V6 is expected to yield 24.5 mpg (US). The hybrid Cayenne will arrive a year later using a lithium ion battery in place of the nickel metal hydride battery that was shown in the prototype at the LA Auto Show last fall.
