Ruf Stormster concept: the electric Porsche Cayenne

Published: 10 December 2009

Ruf might be a tiny German tuner, but it’s just unveiled the first ever electric Cayenne. Called the Stormster it's Ruf's second battery-powered Porsche, uses the same motor as the company's electric 911, weighs close to 2.7 tonnes and hits 62mph in ten seconds.

Is Ruf turning its attention away from massively powerful Porsche 911s?

No at all – in fact, earlier this week Ruf took its 676bhp GT2 to 229mph at the Nardo test track in southern Italy. But Ruf is also experimenting with electric cars, and now the Stormster joins the Greenster as part of its eRuf range of concepts.

Out goes the Cayenne's engine and in comes a Siemens electric motor, with the same 270kW (362bhp) as the Greenster, while the lithium-ion battery back comes Li-Tec Battery GmbH, claimed to be the first manufacturer of li-ion cells in Europe.

The result of the switch from gas-guzzling to zero emissions is an increase from the Turbo’s 2355kg to 2670kg. The 0-62mph sprint is now despatched in ten seconds rather than 5.1, and the top speed is down from 171mph to 94mph, but the upside is a 125-mile range and nothing nasty coming out of the tailpipe.

Of course, a Cayenne still needs to be slightly offensive so while it was unveiled at the European Climate Change Conference in Copenhagen, the Stormster is white and rides on 22-inch wheels.
