Average Fuel Economy Standards for Light Trucks; Model Years 2008-2011

This notice proposes to reform the structure of the corporate average fuel economy (CAFE) program for light trucks and proposes to establish higher CAFE standards for model year (MY) 2008-2011 light trucks. Reforming the CAFE program would enable it to achieve larger fuel savings while enhancing safety and preventing adverse economic consequences. During a transition period of MYs 2008-2010, manufacturers may comply with CAFE standards established under the reformed structure (Reformed CAFE) or with standards established in the traditional way (Unreformed CAFE). This will permit manufacturers to gain experience with the Reformed CAFE standards. In MY 2011, all manufacturers would be required to comply with a Reformed CAFE standard. The reform is based on vehicle size. Under Reformed CAFE, fuel economy standards are restructured so that they are based on a measure of vehicle size called "footprint," the product of multiplying a vehicle's wheelbase by its track width. Vehicles would be divided into footprint categories, each representing a different range of footprint. A target level of average fuel economy is proposed for each footprint category, with smaller footprint light trucks
