Porsche has postponed plans for future hybrid models as top managers express doubts about sales. With Porsche forecasts showing no more the 5 percent market share, the Cayenne Hybrid introduction has been pushed back until 2010. As a result, Porsche sales expectations for the US market are now incorrect. Despite the Cayenne Hybrid Concept being introduced at the Frankfurt Motor Show 2007, Porsche has not given a market debut date for hybrid models.
The hybrid technology is jointly developed with Volkswagen and will be on Audi Q7 hybrid in 2008. The Cayenne, Q7 and VW Touareg are built on the same platform.
Depending on analysis, Porsche will also delay the Panamera Hybrid until 2011 at the earliest and possibly as late as 2013. The base model is coming in 2009.

 

I'd rather see something aimed at the GT.
