The Vehicle Technologies Office has released "Adoption of New Fuel-Efficient Technologies from SuperTruck," a report on the industry's adoption rates of new fuel efficient technologies from the SuperTruck program into its manufacturing lines. For a summary of the report, see the accompanying fact sheet.
The information presented in this report is derived from a variety of sources but is primarily based on discussions with the four industry-led teams participating in the DOE SuperTruck initiative about their general findings and future plans for technologies within the initiative. This information was supplemented with perspectives from technical experts within the DOE Vehicle Technologies Office and public information.
To date, the SuperTruck teams have been very successful at meeting or exceeding the goals set forth by the SuperTruck initiative with suites of technologies that have the potential for achieving market success. A number of SuperTruck technologies are already making market inroads, particularly in the areas of aerodynamics and engine/drivetrain integration. These appeal to current fleet buyers because they are cost effective and are proving to be reliable in service. Other SuperTruck technologies offer the promise of additional fuel savings within the next five or ten years when they are expected to be commercially available, particularly in the areas of more advanced aerodynamics packages and further increases in engine thermal efficiency. SuperTruck teams are having success in commercializing some technologies for fuel efficiency and noted that continued progress in reducing cost and improving reliability is needed for other technology suites to show a positive business case for customers. There are considerations beyond the technical arena, as well, having to do with market sector complexity and Federal regulations (such as the existing U.S. Environmental Protection Agency/Department of Transportation Phase 1 greenhouse gas and fuel efficiency standards and recently proposed Phase 2 standards), that will also drive the ultimate fleet adoption of some of these technologies.
