What is a Gas Guzzler under Federal Regulations?

The Gas Guzzler Tax is only imposed on new passenger cars that fail to achieve minimum fuel economy requirements as per federal standards. The tax is calculated based on the combined fuel economy ratings, which are established in a standardized testing procedure.

It is also worth mentioning that this tax is not imposed on trucks, SUVs, and vans, since they do not belong to the passenger automobile category in this case.

This tax is not imposed on end consumers, but it is imposed on manufacturers and importers. The cost is, however, usually incorporated in the ultimate purchase value of the car.
