Rumors are trickling in that Lamborghini has revealed its new highly-exclusive Lamborghini Reventon Roadster to some select clients. The Roadster is expected to make its official appearance at the Frankfurt Motor Show 2009.

This is a bit interesting. We know Porsche is no stranger to the world of electric and hybrid automotive power. Now a photographer has clicked some photos of a car which he believes is an electric or hybrid Porsche 911 convertible sports car.
