The Frankfurt Auto Show has seen some interesting cars this year. The Opel
Rak-e is certainly one of those cars. Featuring some very unique design cues and running only on electricity, the Rak-e is turning heads as one of the shows premier automobile concepts. The ultra-light city car concept was designed to open a "new chapter in electric mobility." Weighing in at 838lbs and powered by a 5kWh battery, the electric motor puts out 49hp and pushes the concept up to a top speed of 75mph.
