The federal government imposes a fuel economy standard, known as Corporate Average Fuel Economy (CAFE), on vehicles with high horsepower motors in order to encourage automakers to produce more fuel-efficient vehicles. The CAFE standards establish requirements for the average fuel economy of a manufacturer's fleet of vehicles, which includes vehicles with high horsepower motors.

To find out more about the specific CAFE standards and regulations imposed by the federal government, you can visit the official website of the U.S. Environmental Protection Agency (EPA) or the National Highway Traffic Safety Administration (NHTSA). These agencies are responsible for implementing and enforcing the fuel economy standards and can provide you with detailed information on how the regulations are applied to vehicles with high horsepower motors.
