Alois Ruf has been in automotive business for a while and many people have heard about his creations. He worked for Porsche since 1974 and became known with 211-mph Ruf CTR Yellowbird, the fastest production car in the world in 1987. Many of Ruf’s creations have been based on Porsche cars: among them are Ruf Rt 12 and Ruf CTR 3.

But Alois Ruf does not only deal with high-powered vehicles. He works on environmentally friendly cars as well. His company has designed 2010 Ruf eRuf Model A, a battery-operated Porsche. Now the designers work on 2011 Ruf Greenster which is about a year away from production.

The green sports car is based on Porsche 911. It runs on a 270kW motor that provides 362 horsepower and around 700 pound-feet of torque. Driving at about 140 mph an owner might expect the batteries to last for 70 miles, but the designers are working hard on new technologies which are supposed to expand the range. At this point the battery pack becomes fully charged within 6 hours, but it should be reduced significantly soon.

The new 2011 Ruf Greenster is going to be sold worldwide at about $300,000. Ruf says if Porsche agrees to sell 911 body shells without an engine, the green sports car will be even cheaper.
