Requires the Secretary of Energy to provide funding to improve the performance, efficiency, and integration of natural gas powered motor vehicles and heavy-duty on-road vehicles. Authorizes the Secretary to make grants to manufacturers of light and heavy duty natural gas vehicles for the development of engines that reduce emissions, improve performance and efficiency, and lower cost. Expresses the sense of Congress that the Environmental Protection Agency (EPA) should streamline the process for certification of natural gas vehicle retrofit kits to promote energy security and provide incentives to encourage and reward manufacturers who produce natural gas powered vehicles.
