Fuel Consumption Rate = 100/MPG
Where:
MPG = The value for combined fuel economy from § 600.210-12(c) , rounded to the nearest whole mpg.
Fuel Consumption Rate = 100/MPG
Where:
MPG = The combined fuel economy value from paragraph (a) of this section, in miles per kW-hour.
Fuel Consumption Rate = 100/MPG
Where:
MPG = The combined fuel economy value from paragraph (a) of this section, in miles per kilogram of hydrogen.
Annual Fuel Cost = Fuel Price/MPG * Average Annual Miles
Where:
Fuel Price = The estimated fuel price provided by EPA for the type of fuel required for the vehicle. The units are dollars per gallon for gasoline and diesel fuel, dollars per gasoline gallon equivalent for natural gas, dollars per kW-hr for plug-in electricity, and dollars per kilogram of hydrogen for hydrogen fuel cell vehicles.
MPG = The combined fuel economy value from paragraph (a) of this section. The units are miles per gallon for gasoline and diesel fuel, miles per gasoline gallon equivalent for natural gas, miles per kW-hr for plug-in electricity, and miles per kilogram of hydrogen for hydrogen fuel cell vehicles.
Average Annual Miles = The estimated annual mileage figure provided by EPA, in miles.
$/mile = $/mileCD * UF + $/mileCS * (1-UF)
Annual fuel cost = ($/milecity * 0.55 + $/milehwy * 0.45) * Average Annual Miles
