| 49 CFR Parts 523, 531, 534, 536, 537 | Average Fuel Economy Standards, Passenger Cars and Light Trucks, Model Years 2011-2015 Proposes substantial increases in the Corporate Average Fuel Economy (CAFE) standards for passenger cars and light trucks that would enhance energy security by improving fuel economy. Since the carbon dioxide (CO2) emitted from the tailpipes of new motor vehicles is the natural by-product of the combustion of fuel, the increased standards would also address climate change by reducing tailpipe emissions of CO2. Those emissions represent 97 percent of the total greenhouse gas emissions from motor vehicles. Implementation of the new standards would dramatically add to the billions of barrels of fuel already saved since the beginning of the CAFE program in 1975. |

| Rear Visibility NCAP Request for Comment This document requests public comment on the agency’s planned update to the U.S. New Car Assessment Program (NCAP). This update would enhance the program’s ability to recommend to motor vehicle consumers various vehicle models that contain rearview video systems that would substantially enhance the driver’s ability to avoid backover crashes. |
