SC03

The SC03 is a driving cycle used to measure vehicle emissions associated with air conditioning usage. It is used by the US Environmental Protection Agency (EPA) to measure tailpipe emissions and fuel economy of passenger cars on a vehicle dynamometer.

The SC03 is part of the "Supplemental Federal Test Procedure" (SFTP), which was developed to test driving conditions beyond those encountered in the standard highway (HWFET) and city (FTP-75) driving cycles. In 2008, the EPA added the US06 and SC03 supplemental tests, as well as a cold FTP-75, to the original city and highway tests for determination of vehicle fuel economy.
