U.S. President Barack Obama on July 29 announced an agreement with 13 major automakers to increase corporate average fuel economy (CAFE) to 54.5 mpg and 163 g/mi of CO2 by MY2025. The agreement covers the model years 2017 to 2025. Already in effect is a CAFE regime requiring a combined car and light-truck fleet-wide fuel economy to reach 35.5 mpg in MY2016. The increases between MY2017 and 2025 will average 5% annually for passenger cars; for light trucks (e.g., pickup trucks and SUVs), the annual increase will average 3.5% for the first five years and 5% annually for the last four. A midterm review of the 2017-2025 CAFE program is planned. The proposal will be fully and formally introduced in a Federal Register notice of proposed rulemaking by the end of September 2011.
