CAFE mandates a minimum average fuel economy for a manufacturer's fleet of vehicles to be sold in the U.S., and this standard increases over the years.

CAFE mandates a minimum average fuel economy for a manufacturer's fleet of vehicles to be sold in the U.S., and this standard has remained constant since 1975.

CAFE enforces federal emissions standards that increase annually. This standard applies to vehicles of all model years, and older vehicles often have to be modified to meet emissions standards and be legal to drive.

CAFE groups commercial vehicles and light trucks together and sets a minimum average fuel economy for the entire fleet, ensuring that companies manufacturing gas-guzzling commercial trucks also produce fuel-efficient and hybrid vehicles.

CAFE ensures that petroleum-producing companies are producing quality fuels that do not contain lead or sulphur levels above federal standards and contribute to air pollution.

SUVs are often classified as a "light truck" and are exempt from the fuel economy standards put in place for passenger vehicles.

Companies that manufacture fuel-inefficient SUVs also manufacture fuel-efficient subcompact cars, resulting in an average fleet fuel economy that meets CAFE standards.

CAFE standards are not based upon the actual fuel economy of a fleet but rather the progress in fuel economy a manufacturer has made over the years. A fleet with poor fuel economy can be sold in the United States as long as the average fuel economy has improved from fleets of previous years.

Many of these large, fuel-inefficient SUVs were marketed and sold in the United States before CAFE standards were implemented and have thus been "grandfathered" in.

The vast majority of these fuel-inefficient SUVs are equipped with "flex-fuel" technology, which makes them eligible for an exemption from CAFE standards, implemented to encourage consumer purchase of American-produced corn ethanol.
