- Corporate Average Fuel Economy (CAFE)
Federal standards that stipulate a target average fuel economy rating (typically expressed in miles per gallon, or mpg) to be met by passenger vehicles by a certain date. The most recent version of the CAFE law, pending passage by Congress, requires new cars, SUVs, and light trucks to average 35.5 mpg by 2016.
