Thus the fuel savings opportunities in the table state to state effectively restricts the use of HPVs across state are not valid for the entire truck population. There are many lines, the DOE and DOT should consider assigning high other fuel-saving opportunities not shown in Table 9-2, priority to further research and analysis on the potential such as improved engine and driveline efficiency, reduced for fuel savings from uniform, nation-wide size and weight aerodynamic drag of the tractor, and others.
