There are nine car categories, six truck categories, and a вЂњspecial purpose vehicleвЂќ category. This text indicates the category of the vehicle (e.g., Small SUV, Station Wagon, Pickup Truck, etc.) and the best and worst fuel economy within that category for the given model year. Some form of the miles per gallon metric has been on vehicle labels since 1977. Combined fuel economy is a weighted average of City and Highway MPG values that is calculated by weighting the City value by 55% and the Highway value by 45%. This is described in miles per gallon (MPG).Д«oth of these values represent the combined city and highway value. The right-hand fuel economy box displays the fuel economy when the battery is emptied and the vehicle is using gasoline. Think of this as being similar to MPG, but instead of presenting miles per gallon of the vehicleвЂ™s fuel type, it represents the number of miles the vehicle can go using a quantity of fuel with the same energy content as a gallon of gasoline. This is described in miles per gallon of gasoline-equivalent (MPGe). The left-hand fuel economy box on the label displays the fuel economy when operating on electricity. The label for plug-in hybrid electric vehicles displays fuel economy for both modes of operation. Note that hybrid gasoline-electric vehicles that do not have plug-in capability are identified as gasoline vehicles since they only use gasoline. Flexible-Fuel Vehicle: Gasoline-Ethanol (E85).You will see different text and icons on the labels for other vehicles: The upper right corner of the label displays text and a related icon to identify it as a vehicle that can be powered by both gasoline and electricity. A quick guide to the different kinds of hybrids and electric vehicles.
