In the next few years it is expected that fuel economy standards will be imposed on new medium and heavy trucks sold in the U.S. Currently, the estimates of the medium and heavy truck population range from a high of 15 miles per gallon (mpg) for class 2b trucks to a low of 2.5 mpg for class 8a trucks. The chart below shows the range of fuel economy for medium and heavy trucks. Descriptions of the vehicle classes are in the table below.
