Where:
CAFErequired is the required level for a given fleet,
Subscript i is a designation of multiple groups of light trucks, where each group's designation, i.e., i = 1, 2, 3, etc., represents light trucks that share a unique model type and footprint within the applicable fleet.
Productioni is the number of units of light trucks produced for sale in the United States within each ith designation, i.e., which share the same model type and footprint.
TARGETi is the fuel economy target in miles per gallon (mpg) applicable to the footprint of light trucks within each ith designation, i.e., which shares the same model type and footprint, calculated according to Figure 3 and rounded to the nearest hundredth of a mpg, i.e., 35.455 = 35.46 mpg, and the summations in the numerator and denominator are both performed over all models in the fleet in question.
Where:
TARGET is the fuel economy target (in mpg) applicable to vehicles of a given footprint (FOOTPRINT, in square feet),
Parameters a, b, c, and d are defined in Table VI, and
The MIN and MAX functions take the minimum and maximum, respectively of the included values.
