N is the total number (sum) of light trucks produced by a manufacturer;
Ni is the number (sum) of the ith light truck model type produced by a manufacturer; and
Ti is the fuel economy target of the ith light truck model type, which is determined according to the following formula, rounded to the nearest hundredth:
Where:
Parameters a, b, c, and d are defined in Table 5 to this paragraph (a);
e = 2.718; and
x = footprint (in square feet, rounded to the nearest tenth) of the model type.

Where:
CAFErequired is the fleet average fuel economy standard for a given light truck 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 light trucks produced for sale in the United States within eachith designation, i.e., which share the same model type and footprint; and
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 share the same model type and footprint, calculated according to either Figure 3 or 4 to this paragraph (a), as appropriate, 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 6 to this paragraph (a); and
The MIN and MAX functions take the minimum and maximum, respectively, of the included values.
