EPA fuel economy report finds weight and power leveling off, footprint stable

Green Car Congress

EPA recently released the latest edition of its annual report Light-Duty Automotive Technology, Carbon Dioxide Emissions and Fuel Economy Trends. The report is the authoritative reference for real-world fuel economy, technology trends and tailpipe carbon dioxide emissions, for new personal vehicles sold in the US every year since 1975.

mpg increase over the previous year and an increase of nearly 5 mpg since 2004. Fuel economy has now increased in eight of the last nine years; average carbon dioxide emissions are also at a record low of 369 g/mile in model year 2013. Since 1975, half of car production has consistently been within several mpg of each other.
