Light-Duty Automotive Technology and Fuel Economy Trends: 1975 Through 2007
This report, published in September 2007, provides data on the fuel economy and technology characteristics of new light-duty vehicles (cars, minivans, sport utility vehicles, and pickup trucks) for model years 1975 through 2007. EPA projects average real-world fuel economy for Model Year 2007 to be 20.2 miles per gallon, the same as in 2006. There is some uncertainty, however, as the 2007 estimate is based on pre-model-year sales projections provided by automakers to EPA at a time when gasoline prices were lower than today’s levels. This report was released in September 2007. Scroll down to read the report (below).
This report confirms that average fuel economy rose in both 2005 and 2006, the first consecutive annual increases since the mid-1980s. The 20.2 mpg value for 2006 and 2007 is 0.9 mpg higher than that in 2004, reversing a long-term trend of slightly declining fuel economy since a 1987 peak.
Most of the increase in overall fuel economy since 2004 has been because of higher light-truck fuel economy. This is likely due, in part, to higher truck fuel economy standards, which have risen each year since 2005. The overall increase in fuel economy is also due to a slightly lower light-truck market share, which peaked in 2004 at 52% and is projected to be 49% in 2007.
The real-world fuel economy values in this year’s report are based on the new EPA labeling methodology that is being implemented with Model Year 2008 vehicles. For recent model years, on average, the new methodology yields industry-wide fuel-economy estimates that are about 6% lower than past EPA estimates. Accordingly, these values should not be directly compared with corresponding values from previous EPA reports.
