U.S. Department of Energy's Vehicle Technologies Office

What We Do The U.S. Department of Energy's Vehicle Technologies Office supports research, development (RD), and deployment of efficient and sustainable transportation technologies that will improve energy efficiency, fuel economy, and enable America to use less petroleum. These technologies, which include advanced batteries and electric drive systems, lightweight materials, advanced combustion engines, alternative fuels, as well as energy efficient mobility systems, will increase America’s energy security, economic vitality, and quality of life. We collaborate with industry leaders through partnerships like U.S. DRIVE and 21st Century Truck to accelerate the development of advanced technologies, including highly efficient combustion engines and fuels, lightweight materials, and advanced batteries and electric drive systems, as well as to understand opportunities to maximize mobility and minimize energy impact. Our research and development is guided by technology roadmaps and with clear goals and technical targets. Visit our success stories page to explore VTO funded research that led to commercialization.
