While Porsche’s factory backed efforts for a greener tomorrow with the CO2ncept-10% focus on reducing power train loss in order to increase efficiency without the use of a gas/electric hybrid module, the super Porsche tuner from Pfaffenhausen, Alois Ruf has decided to go full tilt, replace the entire driveline and turn the Cayenne into a a bona fide zero emissions sport utility vehicle.

The Ruf Stormster is the world’s first all electric variant of the popular Porsche Cayenne. Not being afraid to push the performance envelope, the Stormster has a lot to live up to, that is why Alois started off by dropping a 367 HP Siemens electric motor powered by a set of longer lasting lithium ion batteries, just like in the 911 derived eRUF sports car. Weighing in at just under 6,000 pounds, the Cayenne is no lightweight, but the BEV Stormster is still able to make a spirited sprint from 0 to 60 MPH in just 10 seconds, reach a top speed of around 93 MPH and run for up to 125 miles on a single charge. Despite being a bit more sluggish than the standard version, you must keep in mind that the Stormster is only the beginning.

Press release

RUF Automobile GmbH, located in the small Bavarian town of Pfaffenhausen, the manufacturer of high performance automobiles, introduced the first electric sports car (eRUF) from Germany in October 2008.

During the Geneva Motor Show, in March 2009, RUF presented an evolution of the first eRUF, widely known as "Greenster". The eRUF family continues to grow with the unveiling of the "Stormster", the very first electrically driven SUV based on the Porsche Cayenne.

The Stormster is driven by a Siemens electric motor, with 270 kW (367 bhp) as in the eRUF sports car. The total weight is 2,670 kg which makes it capable of reaching 100 km/h in only 10 seconds. The top speed is 150 km/h, being able to reach a range of 200 km at one charge.

The lithium ion accumulators are supplied by Li-Tec Battery GmbH. Li-Tec is the first manufacturer of lithium ion battery cells in Europe, designed for the automobile industry using ceramic storage technology.

Hankook developed the winter tires for the all wheel drive Stormster which is fitted to RUF classic 5 spoke lightweight wheels. Tires of size 295/30 R 22 allow the best possible road grip.

The Stormster will have its first public debut during the European Climate Change Conference in Copenhagen, (COP 15), Denmark from December 7th to 18th.

Well all of the cars seems focused on the electric concept cars that they’ve launched this environment friendly car which IMO was in the good lines for a electric car and it’s a SUV so really impressive for Porsche to do such machine.

93 mph is not bad for an SUV hybrid. I mean, if the car is Porsche then it still is a car that can make a statement about the owner. It shows class and luxury, I mean, compare it to driving a hybrid Prius. Which one do you think can get the ladies attention?

lets make it green, good thing that most automotive company like RUF are making their productions more eco friendly, I am amazed that Stormer is a one Hell of a E-CAR imagine Electric power car but it has 367 HP and it can go up 125 Mile on a single charge only.
