The EPA posted its fuel economy figures for the 2009 Ford F-150 and the 2009 Dodge Ram 1500 and both trucks show slight improvements.
The two-wheel drive F-150 jumps from 14/19 mpg city/highway in the 2008 to 15/20 thanks to the upgrade from a two-valve 4.6-liter V-8 with a four-speed automatic to a six-speed automatic and three-valve 4.6-liter V-8. The four-wheel drive version jumps from 13/17 mpg to 14/19. Ford is also pairing its six-speed transmission with the flex-fuel 5.4-liter V-8 further improving fuel economy from 13/18 mpg to 14/20 in 4x2s, and from 13/17 mpg to 14/18 in 4x4 trucks.
The 2009 Dodge Ram still has the same five- speed transmission, and most of its fuel economy gains are garnered from improved aerodynamics and a revised 5.7-liter Hemi V-8 engine. In two-wheel drive models, the 390-horsepower Hemi is rated the same 14/20 mpg as Dodge's 3.7-liter V-6, giving the new 2009s an 8 percent improvement in fuel economy.
