The electric car bandwagon is sure filling up these days with automakers from Chevrolet all the way to Porsche, and many in between, coming up with plans to produce or further market their electric vehicles. Now even tuning firms are following in the automakers' footsteps as RUF, a German tuner, is preparing no less than ten electric sports car based on the Porsche 911->ke282. These 10 models will be manufactured in cooperation with Siemens AG and will be presented in the first half of 2011.

The first of the 10 electric models is called the Single Motor Concept and is based on a 997 Carrera->ke574. It is powered by a 180 KW electric motor that takes its power from lithium-ion batteries with an energy capacity of 29 kWh. The electric motor has a driving range of approximately 150 km (93 miles) and a maximum speed of about 136 mph. The sprint from 0-62mph takes about 7 seconds.

The second electric RUF vehicle is the Twin Motor Concept with 2-speed Gearbox. It features two transversely mounted Siemens synchronous electric motors producing 250 kW (335hp) with double inverters and an automatic 2 speed gearbox with limited slip differential. This model has an autonomy of 200 kilometers (124 miles) and can hit a top speed of 136 mph.

The third concept we have details on is the Twin Motor Concept with Torque Vectoring. This concept features the same two transversely mounted Siemens synchronous electric motors with double inverters as before, but gets two separate angular bevel gearboxes for independent rear wheel drive as well. It can sprint from 0 to 60 mph in about 5 seconds, while top speed is 111 mph.
