INDUSTRY NEWS & ANALYSIS
Starting in 2014, on-highway trucks and vocational vehicles such as this Mack Granite
dump truck, will need to meet greenhouse gas and fuel economy standards thanks
to groundbreaking new rules recently finalized by the U.S. EPA and the U.S. Dept. of
Transportation’s National Highway Traffic Safety Administration.
and 2010 heavy-duty on-highway
engine standards. But even that is
mitigated by the fact that at the begin-
ning at least, no new technology will
be required. To meet the initial levels
of the new regulations will require
refinements more than reinventions,
such as adding more aerodynamic
features to trucks, incorporating drag-
reducing fairings and guards, etc.
2014 to 2018, they divide trucks into
three categories — combination tractors (semi-trucks), heavy-duty pickup trucks and vans, and vocational
vehicles. The joint standards cover
complete vehicles, allowing the agencies to achieve the greatest possible
reductions in fuel consumption and
GHG emissions, while avoiding unintended consequences.
Two types of standard metrics have
been adopted: payload-dependent
gram per mile (and gallon per 100-
mile) standards for pickups and vans;
and gram per ton-mile (and gallon per
1000 ton-mile) standards for vocational vehicles and combination tractors.
Focusing on the specific categories, heavy-duty combination tractors,
the agencies adopted differentiated
standards for nine sub-categories of
combination tractors based on three
attributes: weight class, cab type and
roof height. The standards will phase
in to the 2017 levels as shown in
