SEC. 773. STUDY OF FEASIBILITY AND EFFECTS OF REDUCING USE 
OF FUEL FOR AUTOMOBILES. 
(a) IN GENERAL.—Not later than 30 days after the date of 
the enactment of this Act, the Administrator of the National High-
way Traffic Safety Administration shall initiate a study of the 
feasibility and effects of reducing by model year 2014, by a signifi-
cant percentage, the amount of fuel consumed by automobiles. 
(b) SUBJECTS OF STUDY.—The study under this section shall 
include— 
(1) examination of, and recommendation of alternatives 
to, the policy under current Federal law of establishing average 
fuel economy standards for automobiles and requiring each 
automobile manufacturer to comply with average fuel economy 
standards that apply to the automobiles it manufactures; 
(2) examination of how automobile manufacturers could 
contribute toward achieving the reduction referred to in sub-
section (a);
