Average Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 
2027-2032 and Fuel Efficiency Standards for Heavy -Duty Pickup Tr ucks and Vans for 
Model Years 2030 -2035; (263 page(s), in English)  
6. Description of content:  Notice of proposed rulemaking - NHTSA, on behalf of the 
Department of Transportation (DOT), is proposing new fuel economy standards for 
passenger cars and light trucks and fuel efficiency standards for model years (MYs) 2027 –
31 that increase at a rate of 2 percent per year for passenger cars and 4 percent per year 
for light trucks, and new fuel efficiency standards for heavy -duty pickup trucks and vans 
(HDPUVs) fo r MYs 2030–2035 that increase at a rate of 10 percent per year. NHTSA is 
also setting forth proposed augural standards for MY 2032 passenger cars and light trucks, 
that would increase at 2 percent and 4 percent year over year, respectively, as compared 
to the prior year's standards. NHTSA currently projects that the proposed standards would G/TBT/N/USA/2037

  require an industry fleet -wide average for passenger cars and light trucks of roughly 58 
miles per gallon (mpg) in MY 2032 and an industry fleet -wide average for HDPUVs of 
roughly 2.6 gallons per 100 miles in MY 2038. NHTSA further projects that the proposed 
standards would reduce average fuel outlays over the lifetimes of passenger cars and 
light trucks by $1,043 and of HDPUVs by $439. These proposed standards are direct ly 
responsive to the agency's statutory mandate to improve energy conservation and reduce 
the nation's energy dependence on foreign sources.
