Ruf revealed its first eRuf electric car based on the Porsche 911, back in October 2008, but cramming in enough batteries to give the car a decent range was a tough ask. Using the Cayenne as a base gives Ruf's engineers a bit more room to manoeuvre.
Enter the Stormster, or Stormster Grun, should you choose to get your batteries fitted into Ruf's widebody version of the Cayenne (pictured above).
In fact, at 2670kg, the Stormster is 315kg (or about three-and-a-half fat people) heavier than the heaviest standard Porsche Cayenne - the 493bhp Turbo. That translates to a 0-62mph sprint of around 10 seconds and 94mph top speed, while the Lithium ion batteries give a 125-mile (maximum) range.
Appropriately, the Ruf Stormster is making its public debut not at a glamorous motor show, but at the European Climate Change Conference in Copenhagen. It just gets more and more exciting, doesn't it?
