IITRI Scott McBroom Southwest Research Institute ABSTRACT The U.S. Army's National Automotive Center has contracted with Illinois Institute of Technology Research institute (IITRI), Southwest Research Institute (SwRI), and Advanced Propulsion, LLC, to evaluate the effects on fuel consumption and logistics that would result from hybridizing the powertrains of the Army's tactical wheeled vehicle fleet. This paper will outline the approach taken to perform that evaluation and present a synopsis of results achieved to date. INTRODUCTION The National 21st Century Truck Partnership seeks to develop advanced, commercially viable technologies for a new generation of trucking through partnership between government and industry. The Partnership is a consortium of Federal government agencies (Department of Defense, Department of Energy, Department of Transportation, and the Environmental Protection Agency), major trucking manufacturers, their suppliers and associations, and academic institutions. The U.S. Army represents the Defense Department in the National Partnership because, as the largest governmental owner/operator of medium and heavy truck fleets, it shares many of the challenges facing the commercial truck market, such as achieving greater fuel efficiency, reducing emissions, improving safety, and enhancing performance. The Army's initiative under the national program is known as Future Truck Systems (FTS). FTS is designed to address uniquely military needs, but also to work with industry to develop technologies that have application in the commercial sector, as well as the military. The focal point of FTS is the Army's National Automotive Center (MAC) located within the Tank-automotive Research, Development and Engineering Center (TARDEC). TARDEC is an element of the U.S. Army Tank-automotive and Armaments Command (TACOM) in Warren, Michigan. NAC has contracted with Illinois Institute of Technology Research Institute (IITRI), Southwest Research Institute (SwRI), and Advanced Propulsion, LLC, to evaluate the effects on fuel consumption and logistics that would result from hybridizing the powertrains of the Armys tactical wheeled vehicle fleet. APPROACH The Army approaches the FTS Program utilizing a disciplined systems engineering/systems
