Subaru, unlike other manufacturers is not developing hybrid or electrics, instead they have chosen a much simpler cheaper and older path to go green! by using Bi-fuel system. After Forester, Legacy and Impreza now the small Justy city car is getting the LPG plant. 27 liter LPG tank with the conversion kit is located in the luggage compartment where you expect to find the spare wheel and it also has LED reserve indicator to cheer up the driver who certainly will be disgusted with terrible performance of the LPG fuel!
