Its sister organization, OAAT, focuses on the development of advanced automotive technologies, while OHVT focuses, for the most part, on technologies for trucks. The mission of OHVT is "to conduct in collaboration with our heavy vehicle industry partners and their suppliers, a customer-focused national program to research and develop technologies that will enable trucks and other heavy vehicles to be more energy efficient and capable of using alternative fuels while simultaneously reducing emissions." Fuel use for all classes of trucks is increasing faster than for automobiles.

In addition, OHVT should implement a Go/No Go decision-making framework to keep OHVT programs focused on program goals, to establish or modify priorities and to change directions, as necessary. The diesel engine is the most efficient, economical power plant available today for trucks.

However, if the diesel engine cannot meet emission standards, it will not be a viable alternative for this 3 market segment. Although OHVT's program is focused on addressing the technical barriers to meeting emission standards with diesel engines, OHVT should also keep abreast of progress on other engine types that could meet emission standards more easily, although with poorer fuel economy (e.g., the gasoline engine)

should focus more on factors other than engine efficiency that affect on-road fuel economy, especially improving aerodynamics, reducing the use of accessory power, decreasing rolling resistance, and decreasing unloaded vehicle weight by innovative design incorporating high-strength, weight-reduction materials (in keeping with safety considerations, as well as highway wear and tear)

Finding 8. The Office of Heavy Vehicle Technologies has no systematic process for prioritizing high-strength, weightreduction, materials-related research or for monitoring other relevant, federally funded materials R&D.
