To encourage the availability and use of motor vehicles that have improved fuel efficiency, in order to reduce the need to import oil into the United States.

SECTION 1. FINDINGS.

    The Congress makes the following findings:
            (1) Ensuring secure access to energy is in the highest 
        national security interests of the United States.
            (2) Without secure access to oil supplies, the United 
        States economy, which depends heavily on oil for 
        transportation, could be severely affected. Two-thirds of the 
        oil used in the United States is consumed by the transportation 
        sector.
            (3) In 1973 OPEC placed an embargo on sales of oil to the 
        United States, creating severe oil shortages and driving up oil 
        prices in the United States. OPEC's action was a major factor 
        in the recession which followed shortly thereafter.
            (4) Under the ``Carter Doctrine'', announced by President 
        Carter in 1980, ``An attempt by any outside forces to gain 
        control of the Persian Gulf region will be regarded as an 
        assault on the vital interests of the United States of America, 
        and such an assault will be repelled by any means necessary, 
        including military force.''.
            (5) Following the Iraqi invasion of Kuwait in 1990, the 
        United States sent more than 500,000 troops to the Persian Gulf 
        to expel the Iraqi troops, liberate Kuwait, protect Saudi 
        Arabia, and ensure access to Persian Gulf oil.
            (6) Many major oil producing nations do not share United 
        States values of democracy, freedom of expression, thought, and 
        religion, and equality for women.
            (7) During the Afghanistan conflict and the war on 
        terrorism, many oil producing nations did not openly support 
        the United States campaign to end the terror, and many of the 
        terrorists of September 11 came from major OPEC nations.
            (8) It is in the highest national security interests of the 
        United States to substantially reduce our dependence on oil as 
        soon as possible, to secure our access to oil supplies, and to 
        reduce our dependence on nations which do not share our 
        interests and values.
            (9) Because most oil is consumed by the transportation 
        sector, reduction of our dependence on oil can only come from 
        major increases in fuel efficiency in cars, sport utility 
        vehicles, light trucks, and other vehicles.

        law, that directly or indirectly alters the estimated cost of 
        outstanding loan guarantees (or loan guarantee commitments)

adding at the end the following:

under paragraph (1), the Administrator shall not consider any 
automobile manufactured by the manufacturer for which a credit is 
allowed under section 38(a)(16) of the Internal Revenue Code of 
1986.''.

Summary: Amends the Internal Revenue Code to: (1) allow a tax credit for 25 percent of the cost of certain automobiles, trucks, or vans with fuel efficiency ratings of not less than 40 miles per gallon (35 percent for ratings of not less than 50 miles per gallon); (2) allow a business tax credit for the manufacture or production in the United States of qualified fuel-efficient automobiles for first retail sale; (3) make permanent the tax credit for increasing research activities; and (4) increase the rates of the alternative incremental tax credit for research activities.

Authorizes the Secretary of Energy to provide loan guarantees up to $100 million per loan (up to $1 billion aggregate) to automobile manufacturers for the cost of converting to automobiles with a fuel efficiency rating of more than 40 miles per gallon.

Prohibits the Administrator of the Environmental Protection Agency (EPA) from considering any automobile allowed a fuel-efficiency tax credit under this Act in calculating the average fuel economy of a manufacturer.
