    ``(e) Electric Dual Fueled Automobiles.--
            ``(1) In general.--At the request of the manufacturer, the 
        Administrator may measure the fuel economy for any model of 
        dual fueled automobile manufactured after model year 2015 that 
        is capable of operating on electricity in addition to gasoline 
        or diesel fuel, obtains its electricity from a source external 
        to the vehicle, and meets the minimum driving range 
        requirements established by the Secretary for dual fueled 
        electric automobiles, by dividing 1.0 by the sum of--
                    ``(A) the percentage utilization of the model on 
                gasoline or diesel fuel, as determined by a formula 
                based on the model's alternative fuel range, divided by 
                the fuel economy measured under section 32904(c); and
                    ``(B) the percentage utilization of the model on 
                electricity, as determined by a formula based on the 
                model's alternative fuel range, divided by the fuel 
                economy measured under section 32904(a)(2).
            ``(2) Alternative utilization.--The Administrator may adapt 
        the utility factor established under paragraph (1) for 
        alternative fueled automobiles that do not use a fuel described 
        in subparagraph (A), (B), (C), or (D) of section 32901(a)(1).

        calculate such incentive for such automobiles manufactured by 
        such manufacturer after model year 2015 in accordance with 
        subsection (b).''.
    (e) Conforming Amendment.--Section 32906(b) of title 49, United 
States Code, is amended by striking ``section 32905(e)'' and inserting

SEC. 3. HIGH OCCUPANCY VEHICLE FACILITIES.

    Section 166 of title 23, United States Code, is amended--
            (1) in subparagraph (b)(5), by striking subparagraph (A) 
        and inserting the following:

                agency establishes procedures for enforcing the 
                restrictions on the use of a HOV facility by vehicles 
                listed in clauses (i) and (ii), the State agency may 
                allow the use of the HOV facility by--
                            ``(i) alternative fuel vehicles; and
                            ``(ii) new qualified plug-in electric drive 
                        motor vehicles (as defined in section 30D(d)(1) 
                        of the Internal Revenue Code of 1986).''; and
            (2) in subparagraph (f)(1), by inserting ``solely'' before 
        ``operating''.

SEC. 4. STUDY.

    Not later than 180 days after the date of the enactment of this 
Act, the Secretary of Energy, after consultation with the Secretary of 
Transportation, shall submit a report to Congress that--
            (1) describes options to incentivize the development of 
        public compressed natural gas fueling stations; and
            (2) analyzes a variety of possible financing tools, which 
        could include--
                    (A) Federal grants and credit assistance;
                    (B) public-private partnerships; and
                    (C) membership-based cooperatives.
Output: Alternative Fuel Vehicle Development Act - Creates incentives for the manufacture of dual-fueled automobiles that use alternative fuels other than methanol, denatured ethanol, and other alcohols (non-alcohol, dual-fueled automobiles). Removes the cap on credits under the Corporate Average Fuel Economy (CAFE) program for non-alcohol, dual-fueled automobiles. (The cap on CAFE credits limits the total increase of a manufacturer's average fuel economy attributable to dual-fueled automobiles.) Reduces the minimum driving range for non-alcohol, dual-fueled automobiles. Disallows any petition to lower the driving range below 150 miles for those automobiles.  Revises the formula the Administrator of the Environmental Protection Agency (EPA) uses to calculate fuel economy for dual-fueled automobiles operating with gaseous fuel, such as natural gas or hydrogen. Requires the EPA to apply utility factors based on the driving range for such automobiles. Allows the EPA to use a different methodology to calculate the fuel economy for dual-fueled, electric automobiles.  Makes permanent the state's authority to exempt alternative fuel vehicles from high occupancy vehicle (HOV) lane restrictions. Makes eligible only those alternative fuel vehicles operating solely on alternative fuel, including electric vehicles. Requires the Secretary of Energy (DOE) to report on incentives and financing tools to develop public compressed natural gas fueling stations.
