Sec.  533.6  Measurement and calculation procedures.

    (a) Any reference to a class of light trucks manufactured by a 
manufacturer shall be deemed--
    (1) To include all light trucks in that class manufactured by 
persons who control, are controlled by, or are under common control 
with, such manufacturer; and
    (2) To exclude all light trucks in that class manufactured (within 
the meaning of paragraph (a)(1) of this section) during a model year by 
such manufacturer which are exported prior to the expiration of 30 days 
following the end of such model year.
    (b) The average fuel economy of all nonpassenger automobiles that 
are manufactured by a manufacturer and are subject to Sec.  533.5(b) or 
to Sec.  533.5(c) shall be determined in accordance with procedures 
established by the Administrator of the Environmental Protection Agency 
under section 503(a)(2) of the Act.

    Appendix A--Example of Calculating Compliance Under Sec.  533.5 
                              Paragraph (g)

    Assume a hypothetical manufacturer (Manufacturer X) produces a fleet 
of light trucks in MY 2008 as follows:

------------------------------------------------------------------------
                                            Fuel               Footprint
                 Model                    economy     Volume     (ft\2\)
------------------------------------------------------------------------
A......................................       27.0      1,000       42.0
B......................................       25.6      1,500       44.0
C......................................       25.4      1,000       46.0
D......................................       22.1      2,000       50.0
E......................................       22.4      3,000       55.0
F......................................       20.2      1,000       66.0
------------------------------------------------------------------------

    Note to Appendix A Table 1. Manufacturer X's required corporate 
average fuel economy level under Sec.  533.5(g) would be calculated by 
first determining the fuel economy target applicable to each vehicle as 
illustrated in ``Appendix A Figure 1:''

                         ``Appendix A Figure 1''

------------------------------------------------------------------------
                                                           MY 2008 fuel
                  Model                      Footprint        economy
                                              (ft\2\)      target (mpg)
------------------------------------------------------------------------
A.......................................            42.0           26.20
B.......................................            44.0           25.50
C.......................................            46.0           24.80
D.......................................            50.0           23.30
E.......................................            55.0           21.70
F.......................................            66.0           20.30
------------------------------------------------------------------------

    Note to Appendix A Figure 1. Accordingly, vehicle models A, B, C, D, 
E, and F would be compared to fuel economy values of 26.20, 25.50, 
24.80, 23.30, 21.70, and 20.30 mpg, respectively. With the appropriate 
fuel economy targets calculated, Manufacturer X's required fuel economy 
would be calculated as illustrated in ``Appendix A Figure 2.''

    Note to Appendix A Figure 3. Since the actual average fuel economy 
of Manufacturer X's fleet is 23.2 mpg, as compared to its required fuel 
economy level of 23.1 mpg, Manufacturer X complies with the Reformed 
CAFE standard for MY 2008 as set forth in Sec.  533.7(g).
