Across France for 10 Cents
The electrical prototype of the Polyjoule team is the most energy efficient vehicle in the world. During the EducEco Challenge competition (from May 2-4, 2012), on the Nogaro circuit in Gers, France, the all electrical prototype of Polyjoule got the result of 10,017 km with the energy equivalent of 1 liter (a bit less than a third of a gallon) of oil.
The context of this competition is the same as that of Shell* Eco-marathon. The aim is to do a given number of laps, with an average speed of 30km/h (19 mph), and to use a minimum of energy! Our prototype was powered by a battery which allowed the electrical engine to spin the wheel. At
