Center Overview

The Center for Efficient Vehicles and Sustainable Transportation Systems (EV-STS) conducts and disseminates applied research on technologies, methodologies, and tools that facilitate the design, manufacture, deployment, and operation of energy efficient, environmentally sustainable ground vehicles. Its mission is to dramatically improve the energy efficiency and environmental sustainability of ground vehicles through collaborative research among corporate, utility, government, and academic stakeholders in the automotive and ground transportation industries. These vehicles include passenger cars, light- and heavy-duty trucks, and motorized off-road equipment. The mission encompasses both vehicle-level technologies and transportation systems and reflects the inherent complexity and global nature of the automotive and ground transportation industries.
