Chapter 329 - AUTOMOBILE FUEL ECONOMY (§§ 32901 - 32919)
Section 32905 - Manufacturing incentives for alternative fuel automobiles

(a) Dedicated Automobiles.—Except as provided in subsection (c) of this section or section 32904(a)(2) of this title, for any model of dedicated automobile manufactured by a manufacturer after model year 1992, the fuel economy measured for that model shall be based on the fuel content of the alternative fuel used to operate the automobile. A gallon of a liquid alternative fuel used to operate a dedicated automobile is deemed to contain .15 gallon of fuel.

(b) Dual Fueled Automobiles.—Except as provided in subsection (d) of this section or section 32904(a)(2) of this title, for any model of dual fueled automobile manufactured by a manufacturer in model years 1993 through 2019, the Administrator of the Environmental Protection Agency shall measure the fuel economy for that model by dividing 1.0 by the sum of—

(1) .5 divided by the fuel economy measured under section 32904(c) of this title when operating the model on gasoline or diesel fuel; and

(2) .5 divided by the fuel economy—

(A) measured under subsection (a) when operating the model on alternative fuel; or

(B) measured based on the fuel content of B20 when operating the model on B20, which is deemed to contain 0.15 gallon of fuel.

(c) Gaseous Fuel Dedicated Automobiles.—For any model of gaseous fuel dedicated automobile manufactured by a manufacturer after model year 1992, the Administrator shall measure the fuel economy for that model based on the fuel content of the gaseous fuel used to operate the automobile. One hundred cubic feet of natural gas is deemed to contain .823 gallon equivalent of natural gas. The Secretary of Transportation shall determine the appropriate gallon equivalent of other gaseous fuels. A gallon equivalent of gaseous fuel is deemed to have a fuel content of .15 gallon of fuel.

(d) Gaseous Fuel Dual Fueled Automobiles.—For any model of gaseous fuel dual fueled automobile manufactured by a manufacturer in model years 1993 through 2019, the Administrator shall measure the fuel economy for that model by dividing 1.0 by the sum of—

(1) .5 divided by the fuel economy measured under section 32904(c) of this title when operating the model on gasoline or diesel fuel; and

(2) .5 divided by the fuel economy measured under subsection (c) of this section when operating the model on gaseous fuel.

(e) Fuel Economy Calculations.—The Administrator shall calculate the manufacturer's average fuel economy under section 32904(a)(1) of this title for each model described under subsections (a)–(d) of this section by using as the denominator the fuel economy measured for each model under subsections (a)–(d).

(f) Fuel Economy Incentive Requirements.—In order for any model of dual fueled automobile to be eligible to receive the fuel economy incentives included in section 32906(a) and (b), a label shall be attached to the fuel compartment of each dual fueled automobile of that model, notifying that the vehicle can be operated on an alternative fuel and on gasoline or diesel, with the form of alternative fuel stated on the notice. This requirement applies to dual fueled automobiles manufactured on or after September 1, 2006.

In subsections (a) and (c), the words “after model year 1992” are substituted for “Subsections (a) and (c) shall apply only to automobiles manufactured after model year 1992” because of the restatement.

In subsections (b) and (d), before each clause (1), the words “in model years 1993–2004” are substituted for “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” to eliminate unnecessary words and because of the restatement.

In subsection (c), the words “For purposes of this section” and “than natural gas” are omitted as unnecessary because of the restatement. The words “a gallon equivalent of natural gas” are omitted as being included in “A gallon equivalent of any gaseous fuel”.

In subsection (e), the words “subject to the provisions of this section” are omitted as unnecessary because of the restatement. The words “for each model described under subsections (a)–(d) of this section” are substituted for “for each model type of dedicated automobile or dual fueled automobile” to eliminate unnecessary words. The words “by using as the denominator” are substituted for “by including as the denominator of the term” for clarity.
