Search 49 U.S.C. § 32906 : US Code - Section 32906: Maximum fuel economy increase for alternative fuel automobiles

(a) Maximum Increases. - (1)(A) For each of model years 1993-2010
for each category of automobile (except an electric automobile),
the maximum increase in average fuel economy for a manufacturer
attributable to dual fueled automobiles is 1.2 miles a gallon.
(B) If the application of section 32905(b) and (d) of this title
is extended under section 32905(f) of this title, for each category
of automobile (except an electric automobile) the maximum increase
in average fuel economy for a manufacturer for each of model years
2011-2014 attributable to dual fueled automobiles is .9 mile a
gallon.
(2) In applying paragraph (1) of this subsection, the
Administrator of the Environmental Protection Agency shall
determine the increase in a manufacturer's average fuel economy
attributable to dual fueled automobiles by subtracting from the
manufacturer's average fuel economy calculated under section
32905(e) of this title the number equal to what the manufacturer's
average fuel economy would be if it were calculated by the formula
in section 32904(a)(1) of this title by including as the
denominator for each model of dual fueled automobile the fuel
economy when the automobiles are operated on gasoline or diesel
fuel. If the increase attributable to dual fueled automobiles for
any model year described -
(A) in paragraph (1)(A) of this subsection is more than 1.2
miles a gallon, the limitation in paragraph (1)(A) applies; and
(B) in paragraph (1)(B) of this subsection is more than .9 mile
a gallon, the limitation in paragraph (1)(B) applies.
(b) Offsets. - Notwithstanding this section and sections 32901(c)
and 32905 of this title, if the Secretary of Transportation reduces
the average fuel economy standard for passenger automobiles for any
model year below 27.5 miles a gallon, an increase in average fuel
economy for passenger automobiles of more than .7 mile a gallon to
which a manufacturer of dual fueled automobiles would otherwise be
entitled is reduced by an amount equal to the amount of the
reduction in the standard. However, the increase may not be reduced
to less than .7 mile a gallon.
