102 STAT. 2449

"(e) FUEL ECONOMY CALCULATION.—The EPA Administrator shall * calculate, subject to the provisions of this section, the manufacturer's average fuel economy under section 503(a)(1) and (2) by including as the denominator of the term for each model type of alcohol powered automobile, dual energy automobile, natural gas powered automobile, or natural gas dual energy automobile, the fuel economv measured pursuant to subsections (a) through (d) of this section. (f) APPLICABILITY.—

"(1) Except as otherwise provided in this subsection, subsections (b) and (d) shall apply only to automobiles manufactured in model year 1993 through model year 2004.

"(B) If the application of subsections (b) and (d) is extended under subsection (fK2), for each category of automobiles the maximum increase in average fuel economy for a manufacturer for each of the model years 2005 through 2008 attributable to dual energy automobiles and natural gas dual energy automobiles shall be 0.9 miles per gallon. "(C) For purposes of applying subparagraph (A) or (B), the EPA Administrator shall compute the increeise in a manufacturer's average fuel economy attributable to dual energy automobiles and natural gas dual energy automobiles by subtracting from the manufacturer's average fuel economy calculated under subsection (e) the number equal to what the manufacturer's
