The Vehicle Systems research and development (R&D) subprogram within the DOE Vehicle Technologies Office (VTO) provides support and guidance for many cutting-edge automotive technologies under development. Research focuses on addressing critical barriers to advancing light-, medium-, and heavy-duty vehicle systems to help maximize the number of electric miles driven and increase the energy efficiency of transportation vehicles. The work of this program is described on the BenchmarkingModeling and SimulationIntegration, Validation, and Testing Tools and Procedures; and Parasitic Loss Reduction pages.

This report describes the progress made on the research and development projects funded by the Vehicle Systems subprogram.  Past years' reports are listed on the Annual Progress Reports page.
