We already reported about the German Porsche Tuner Ruf introducing a full electric Porsche dubbed eRuf. At the Geneva Motor show Ruf showed the next generation of their electric Porsche called eRuf Greenster.

Today a press-release hit the wire detailing the upcoming plans for the electric Porsche featuring technology now from Siemens and LTC/Gaia for the batteries.

Siemens Corporate Technology has developed an adapted power train for the eRuf Greenster. A preliminary version of the concept for the innovative eDrive from Siemens will already be on display in Geneva. While the vehicle to be presented in Geneva is still equipped with a central motor with a power output of 270 kW and 950 Nm torque, the following version will be produced as a small series with Ruf as a double-motor concept with the innovative integral eDrive.
As such, the eRUF will be the world’s first electric vehicle fitted with a bi-directional network connection, which – without the otherwise necessary additional recharging electronics – is capable to be recharged in less than an hour at a 400-volt power outlet – and can use the same power outlet to feed energy back into the power network if required.

The small series planned on the basis of this concept by RUF Automobile is expected to hit the streets in 2010.
