Last fall, Porsche high performance tuning specialist Ruf announced it had built a prototype electric sports car called the eRuf, which was essentially a lithium ion battery-powered 911. That was just the beginning of the story, as the company has brought the Greenster here to the Geneva Motor Show. The Greenster is a targa top 911 in the old style with a chopped speedster-type windshield. In the back sits a 270kW Siemens electric motor with 695 lb-ft of torque. The battery pack system has been improved and is now 30% smaller in volume, restoring the front trunk space that was lost on the original. The battery pack also has greater power capacity allowing it to release and absorb power faster, enabling more regenerative braking capacity. The battery can apparently be charged in only one hour from a 400V outlet. The next iteration will switch to a twin motor setup and the company is planning a small series production run in 2010.
