| 摘要： | This report summarizes key trends in fuel economy and technology usage related to model year (MY) 1975 through 2007 light-duty vehicles sold in the United States. Light-duty vehicles are those vehicles that EPA classifies as cars or light-duty trucks (sport utility vehicles, vans, and pickup trucks with less than 8500 pounds gross vehicle weight ratings). Since 1975, overall new light-duty vehicle fuel economy has moved through four phases: (1) a rapid increase from 1975 through the early 1980s, (2) a slower increase until reaching its peak in 1987, (3) a gradual decline until 2004, and (4) an increase in 2005 and 2006, with 2007 levels projected to be similar to 2006. |
