[AI summary unavailable — showing source text] Heavy Duty Hybrid Vehicle Research, Development, and Demonstration Act of 2011 - Directs the Secretary of Energy (DOE) to establish a competitive program to provide between three and seven grants of up to $3 million to each recipient for each of three years to advance research and development and to demonstrate technologies, including plug-in hybrid technology, for advanced heavy duty hybrid vehicles (vehicles with a gross weight between 14,000 and 56,000 pounds that are fueled, in part, by a rechargeable energy storage system, excluding truck tractors). Requires that each grant recipient complete two phases: (1) phase one, research and demonstration of advanced hybrid technology by producing or retrofitting one or more advanced heavy duty hybrid vehicles; and (2) phase two, demonstration of advanced manufacturing processes and technologies by producing or retrofitting a minimum of 50 advanced heavy duty hybrid vehicles. Directs the Secretary to: (1) conduct research into alternative power train designs for use in advanced heavy duty hybrid vehicles; and (2) establish a pilot program through the National Laboratories and Technology Centers of the Department of Energy to research an…
