The U.S. Department of Energy (DOE) and U.S. Environmental Protection Agency (EPA) have developed the fuel economy website, https://www.fueleconomy.gov/. The website features updated fuel economy data for new and used passenger vehicles dating back to 1984, allows side-by-side vehicle comparisons, and offers fuel-saving tips. The website also contains vehicle-specific air pollution emissions information and safety ratings and provides links to car buying websites.
