Here we have the Stormster based off the Porsche Cayenne, and it is the first electric SUV brought to us by eRUF Automobile. eRUF has revealed their latest work on the SUV after unveiling the first electric sports car back in October 2008. This will be their third installment of an electric vehicle that is powered by a Siemens Technology electric unit. The numbers are remarkable for being completely electric, showing 367 bhp, which is the same as the previous Greenster Porsche model. Debuting at the European Climate Change Conference in Copenhagen, the Porsche Cayenne SUV will be displayed from December 7th to the 18th of this month.
