Detroit Free Press. The National Highway Traffic Safety Administration, the owner of the CAFE program, estimates that 2007 model year fuel economy in the US will increase to 26.4 mpg US, surpassing the previous high of 26.2 mpg in 1987.
The increase of 1 mile per gallon, or 3.9%, from the 2006 models follows two years of no change in the fleet average.
The NHTSA says the average fuel economy of cars is expected to rise by 1.2 to 31 mpg, while the light truck average is expected to rise by 0.7 to 22.9. Among cars, domestically built models are expected to increase their fuel economy by 0.4 to 30.5 mpg, while imported cars are expected to post the largest gain of 1.2 mpg to 31.7 mpg.
The numbers exclude the largest models and could be revised once automakers and the NHTSA collect actual sales data of 2007 models.
