The US Government announced new vehicle fuel efficiency standards that pull together the national plan and that California and other states were proposing. All vehicle classes will need to improve, preventing manufacturers from producing just a few very efficient vehicles to balance out not improving the efficiency of SUVs and trucks. The minimum overall standard will be 35.5 mpg by 2016. Cars will need an average of 39 mpg and trucks will need to get 30 mpg. This represents about a 30% increase from current standards.
