Corporate Average Fuel Economy (CAFE)

The U.S. DOT Volpe Center's Corporate Average Fuel Economy (CAFE) Program Office develops and executes analyses to assess the costs and benefits of national fuel economy standards—part of the National Highway Traffic Safety Administration’s (NHTSA) safety mandate. CAFE standards consider future-year impacts, including vehicle demand, which have implications for highway infrastructure needs.

We serve as a primary technical resource for the NHTSA CAFE program, partnering with the agency to manage and implement all aspects of NHTSA’s fuel economy program. We also provide key technical support to NHTSA throughout the complex federal rule-making process.
