CalCars boasts its plug-in hybrid vehicle can get more than 100 miles per gallon.  The prototype car uses a lithium-ion battery.  It was converted from a Toyota Prius by EnergyCS/EDrive, a Monrovia, California-based company.  There is also a Canadian company that does the conversions.  Conversions will soon be commercially available, but the cost may run from $10-12,000.
