Vehicle Technologies Office

The U.S. Department of Energy's Vehicle Technologies Office supports research, development (R&D), and deployment of efficient and sustainable highway transportation technologies to improve vehicles’ fuel economy and minimize petroleum use. These technologies, which include plug-in electric vehicles (also known as EVs or electric cars), batteries, electric drive technologies, advanced combustion engines, lightweight materials, and alternative fuels, will increase Americans’ energy security, lower costs, and reduce environmental impacts.
