Medium- and heavy-duty vehicles serve as the backbone of America s economy, playing a vital role in moving freight and passengers. These trucks also perform essential duties in other parts of society, such as maintaining our electric power infrastructure, collecting refuse, and maintaining the highway system. Improving the vehicle efficiency of freight transportation is vital to helping the country decrease its petroleum use as the economy grows. Leading the way, the 21st Century Truck Partnership (21CTP) addresses these important national challenges related to medium-duty and heavy-duty truck efficiency, safety, and emissions by pursuing collaborative research and development among government and industry partners. The overall vision of 21CTP is for the nation's trucks and buses to safely and cost-effectively move larger volumes of freight and greater numbers of passengers while emitting little or no pollution and dramatically reducing the dependency on foreign oil. |
