Electricity and high-performance cars may or may not mix, depending on your frame of reference, but whether you're a Tesla fan or a Formula 1 devotee, it's easy to agree that an all-electric Porsche 911 would be a welcome creation. Porsche's Wolfgang Durheimer recently discussed the issue, but despite his hints, revealed no plans for production.

Even if Porsche does build an all-electric 911, it's too late to be the first to do so - RUF has completed and is preparing for production of the Greenster (pictured below), a pure EV built from a production 911 Cabrio.

But don't let your mouth start watering with dreams of unlimited torque, instant response, four-wheel motors and continuous traction control - all marshaled with Porsche finesse and handling - just yet.

Durheimer says that while RUF's creation is a masterpiece, it doesn't have to deal with the production-vehicle realities of ample cargo room and light weight that a Porsche-built 911 EV would require.

He has a strong point - though impressive, the RUF Greenster weighs in at a hefty 3,750lb (1695kg) and produces 362hp (270kW) - enough to shuffle to 62mph (100km/h) in just five seconds, but hardly Porsche 911-territory.

Nevertheless, the fact that Durheimer has paid so much attention to the RUF project and is willing to discuss it hints at the possibility of an electric future at Porsche.
