The State of Michigan, along with other states, is required under the Energy Policy Act (EPACT) of 1992 to acquire alternative fuel vehicles (AFVs) as an increasing percentage of new fleet vehicle purchases each year. AFVs run on electricity, ethanol (E-85), methanol (M-85), natural gas, or propane. Most of the AFVs purchased are E-85 flexible fuel vehicles (FFVs), since they are offered at the same price as their gasoline counterparts. FFVs are designed to run on various blends of gasoline and ethanol from 100% gasoline to 85% ethanol (E-85). Automakers are manufacturing new models of FFVs each year. The State of Michigan now owns or leases more than 2,128 FFVs and 34 CNG vehicles and 18 hybrid vehicles.
